Sejanus21 # OUTDOOR 2026 | Week 1 — Seedling Stage **Day count:** 11 days since germination (May 6) **Date:** May 17, 2026 **Environment:** Basement under SanLight EVO 3-80, 18h photoperiod · 22°C avg · 62% RH · gentle fan running continuously --- ## ENVIRONMENT & CARE The seedlings spent the entire week in the basement. Outdoor temperatures dropped to 8–9°C mid-week — far too cold for this stage — so the plan to transition them to the greenhouse was postponed. No regrets: the controlled basement environment delivered consistent warmth and light, and the results speak for themselves. Watering: approximately every three days, 100–200ml per pot depending on plant size. No fertilizer additions beyond the Multicote 6M slow-release depot already incorporated into the substrate. Occasional Fulvital Plus Liquid remains the only option at this stage if a gentle push is needed. --- ## PLANT-BY-PLANT ASSESSMENT (Day 13) **Mendocino Skunk** — *Group leader* The standout of the week. Second true leaf pair well developed, broad five-fingered leaves, strong stem. Clearly ahead of the pack and showing exactly the vigorous, compact growth the Skunk × White Widow × Critical 2 lineage promises. The Tommy Chong Edition appears to be more than marketing. **CBDRelax** — *Close second* Second true leaf pair unfolding, rich dark green colour. Keeping pace with Mendocino Skunk and confirming the solid performance already known from the indoor winter grow 2025/26. The indica-dominant structure is showing in the broad leaf shape. **Mellowz** (Compound Genetics, Spritzer × Grape Gas) — *On track* First true leaf pair fully developed, second emerging. Solid, healthy-looking growth for a first-time outdoor Compound Genetics plant at 51°N. The Spritzer lineage tends toward vigorous veg — so far confirmed. **Runtz Carlton** (Compound Genetics, White Runtz × Eye Candy) — *Pleasantly surprised* Was the most compact at transplant; has caught up well. First true leaf pair fully developed, symmetric and clean. A good sign for a strain that will need all the veg time it can get before the season turns. **Tropical Fruit Cake** — *Resilient* Smaller than the others but stable, green, and clearly developing its first true leaf pair. Considering this seedling lost its seed shell and part of its taproot during transfer to the Jiffy, the recovery is impressive. Strong genetics from a brand-new Paradise Seeds variety. **CBDelight** — *Recovering as expected* Smallest of the group, with a structural handicap from the Jiffy detaching at transplant. However: first true leaf pair now visible, stem stabilising. This strain delivered nearly 200g outdoor last season — the slow start is circumstantial, not genetic. No concern at this point. --- ## WEEK HIGHLIGHT Six seeds. Six plants. Zero casualties — including one with a broken taproot and one with a detached Jiffy. The germination rate and early seedling resilience confirm why Paradise Seeds is a premium genetics supplier. The two Compound Genetics strains (Mellowz, Runtz Carlton) also showed clean, problem-free germination on their first outing. --- ## WHAT'S NEXT Outdoor temperatures are forecast to improve next week. The plan is to begin gradual hardening — short daytime sessions in the greenhouse — once nights stay reliably above 12°C. Final container transplant (12.5L and 20L Airpots, Mendocino Skunk into the garden bed under the quince tree) follows once the plants have filled the 1L Airpots sufficiently. *Next update: Week 2*

Sejanus21 # OUTDOOR 2026 | Week 2 — Early Veg & Hardening Begins **Day count:** 18 days since germination (May 6) **Date:** May 24, 2026 **Environment (week avg):** Basement · 22°C · 66% RH · SanLight EVO 3-80 · gentle fan **Since May 23:** Daytime hardening sessions in greenhouse (30°C outdoor temps) --- ## ENVIRONMENT & CARE The seedlings spent most of the week in the basement under the SanLight EVO 3-80. Yesterday the hardening phase began: plants move to the greenhouse during the day and return to the basement at night. With outdoor temperatures hitting 30°C, no complaints on that front. Watering: every three days until May 23, then daily as the greenhouse heat demands it. No fertilizer beyond occasional Fulvital Plus liquid. The Multicote 6M slow-release depot in the substrate continues to provide background nutrition. --- ## PLANT-BY-PLANT (Day 18) **Mendocino Skunk** — Dominant. Seven-fingered leaves, strong main stem, clearly the largest plant in the group. Ready for the final container as soon as conditions allow. **CBDRelax** — Excellent. Third true leaf pair fully open, broad and dark green. Running close behind Mendocino Skunk and exactly on form for a strain that already proved itself in the indoor winter grow. **Tropical Fruit Cake** — Surprise of the week. Has caught up significantly; narrow sativa-type fingers, second/third leaf pair visible. Elegant growth habit for a new Paradise Seeds variety. **Runtz Carlton** — Solid. Compact and symmetric, second leaf pair well developed. **Mellowz** — Characteristically wide and flat growth pattern, consistent with the Spritzer lineage. First leaf pair broad, second developing. **CBDelight** — Has almost fully closed the gap left by the Jiffy incident at transplant. First and second leaf pair now present, stem stable. No further concern — this strain delivered close to 200g outdoor last season and the genetics know what they're doing. --- ## WEEK HIGHLIGHT The jump in growth between Day 11 and Day 18 was striking across the board. The combination of consistent basement conditions and — crucially — no overwatering or premature fertilization seems to be paying off. The Multicote depot does its job quietly in the background. First impressions of the Compound Genetics strains outdoors at 51°N: both Mellowz and Runtz Carlton are developing cleanly. The real test comes in late summer. --- ## WHAT'S NEXT Final container transplant approaching — Mendocino Skunk first, directly into the garden bed under the quince tree. The remaining five follow into their Airpots (20L for the CBD strains, 12.5L for the THC strains) once the 1L pots are sufficiently rooted. Active fertilization begins with the final transplant. *Next update: Week 3*

Sejanus21 # OUTDOOR 2026 | Week 3 — Veg in Full Swing **Day count:** 25 days since germination (May 6) **Date:** May 31, 2026 **Environment:** Greenhouse full-time all week · 22°C avg · 12°C min (night) / 31°C max (day) · 63% RH **Watering:** ~100ml ground water per plant per day · Fulvital Plus liquid added regularly --- ## ENVIRONMENT & CARE First full week in the greenhouse. The temperature swings are significant — 12°C at night, up to 31°C during the day — but the plants handled it without complaint. No fertilizer beyond Fulvital Plus; the Multicote 6M slow-release depot and the pre-fertilized substrate continue to do the heavy lifting. --- ## PLANT-BY-PLANT (Day 25) **Mendocino Skunk — 39cm** · Dominant. Strong stem, broad multi-fingered leaves, clearly a class above the rest in size. Ready for the garden bed. Topping above the 4th node planned imminently. **CBDRelax — 25cm** · Upright, healthy stretch, good colour. Running second and developing exactly as expected from a strain already proven in the indoor winter grow. **Mellowz — 24cm** · Wide and flat growth pattern, consistent with the Spritzer lineage. Dense canopy developing. **Tropical Fruit Cake — 18cm** · Narrow sativa-type fingers, elegant structure. Still one of the most visually interesting plants in the group for a new variety. **Runtz Carlton — 16cm** · Compact, symmetric, clean. Taking its time but building a solid structure. **CBDelight — 13cm** · Smallest of the group, still carrying the deficit from the Jiffy incident at transplant. Developing cleanly and closing the gap gradually. No concern — this strain knows what it's doing. --- ## WHAT'S NEXT Topping Mendocino Skunk above the 4th node this week, then transplanting all remaining plants into their final containers on Thursday: 20L Airpots for CBDelight and CBDRelax, 12.5L Airpots for Mellowz, Runtz Carlton and Tropical Fruit Cake. Mendocino Skunk goes directly into the garden bed under the quince tree. Active fertilization begins with the final transplant. *Next update: Week 4*

Sejanus21 # OUTDOOR 2026 | Week 4 — Final Transplant & First Month Complete **Day count:** 32 days since germination (May 6) **Date:** June 7, 2026 **Environment (week avg):** Greenhouse · 17°C avg · 10°C min / 28°C max · 84% RH **CBDRelax:** outdoors under canopy since June 6 --- ## ENVIRONMENT & CARE A week of transitions. All plants spent most of the week in the greenhouse, with CBDRelax moving permanently outdoors under a covered canopy on June 6 — the first plant to leave the protected environment for good. Watering: tap water with Fulvital Plus Liquid throughout. Dynomyco Spark applied at transplant. No active fertilizer program yet — the Multicote 6M slow-release depot in the final substrate handles background nutrition for now. Full fertilization starts next week. --- ## FINAL TRANSPLANT COMPLETE The last transplants happened June 5–6. All plants are now in their final containers: - **CBDelight + CBDRelax** → 20L Airpots - **Mellowz + Runtz Carlton + TFC** → 12.5L Airpots - **Mendocino Skunk** → 12.5L Airpot (intermediate; garden bed under quince tree to follow once slug protection is in place) Roots were well air-pruned in the 1L Airpots — exactly what the system is designed for. --- ## PLANT-BY-PLANT (Day 32) **Mendocino Skunk — 37cm** · Topped above node 4 on June 1. The slug that attacked the fresh cut damaged one of the two shoots at the topping site — it remains uncertain whether it will fully develop. The two shoots from the node below are growing well, so a minimum of three strong colas is the realistic expectation. A fourth is possible if the compromised top shoot recovers. **Mellowz — 35cm** · Wide, lush, characteristic Spritzer growth pattern. The largest untopped plant in the group. **CBDRelax — 31cm** · Strong multi-node development, healthy and vigorous. First plant permanently outdoors. **TFC — 30cm** · Slim, upright, narrow sativa-type leaves. Developing elegantly for a new variety. **Runtz Carlton — 25cm** · Compact with good node structure. Taking its time but building a solid base. **CBDelight — 19cm** · Still the smallest, still carrying the deficit from the Jiffy detachment at transplant. Developing steadily — no concern. The 20L container gives it plenty of room to close the gap. --- ## WEEK HIGHLIGHT Month one complete. 6/6 germination, 6/6 plants in final containers, first outdoor placement. The only unplanned event was the slug attack on Mendocino Skunk post-topping — manageable and partially resolved. --- ## WHAT'S NEXT Topping CBDRelax, Mellowz, TFC and Runtz Carlton on Tuesday or Wednesday. CBDelight depending on status. Active fertilization begins: Plagron Alga Grow as base, Calcinit and Fulvital Plus as supplements. Mendocino Skunk into the garden bed once slug protection (Ferramol) is secured around the planting area.

Sejanus21 OUTDOOR 2026 | Week 5 — Topping Recovery & First Fertilization Day count: 39 days since germination (May 6) Date: June 14, 2026 Environment (week avg): Greenhouse · 17°C avg · 9°C min / 26°C max · 80.5% RH All plants: Greenhouse throughout — post-topping recovery period before moving outdoors ENVIRONMENT & CARE A cool week across the board, with nights dropping to 9°C. All plants stayed in the greenhouse to recover from topping before being moved to their outdoor positions. Watering every three days at approximately 1L per plant. First active fertilization this week: Plagron Alga Grow at 1.5ml/L, combined with Fulvital Plus Liquid. The Multicote 6M slow-release depot has been carrying background nutrition since transplant; liquid feeding now supplements it as the plants enter active vegetative growth post-topping. PLANT-BY-PLANT (Day 39) Mendocino Skunk — 52cm · The standout of the week. 15cm of growth despite consistently cool temperatures — the genetics clearly want to move. Multiple side shoots developing well after the June 1 topping. The slug incident is no longer visible in the plant's structure. Mellowz — 38cm · Wide canopy developing as expected for the Spritzer lineage. Topping recovery clearly underway with new lateral growth. CBDRelax — 32cm · Back in the greenhouse this week after topping on June 11. Topping recovery progressing well. Will return to the outdoor canopy position once the new shoots are established. TFC — 30cm · Compact and elegant. Topping recovery on track; the narrow sativa-type leaf structure remains the most visually distinctive in the group. Runtz Carlton — 27cm · Deep green, broad leaves, solid node structure. Topping recovery proceeding cleanly. CBDelight — 21cm · Smallest of the group, still. Topping recovery underway with lateral shoots becoming visible. The 20L container gives it room to compensate over the coming weeks. WEEK HIGHLIGHT All six plants now topped. The transition from nursery phase to structured vegetative growth is complete. Mendocino Skunk's 52cm despite a cool week is a strong indicator of what this strain will do once summer temperatures arrive consistently. WHAT'S NEXT Move plants progressively outdoors as topping recovery consolidates. Mendocino Skunk into the garden bed under the quince tree once slug protection is secured. Fertilization continues with Plagron Alga Grow; Calcinit to be added as calcium-nitrogen supplement. Warm weather forecast from this weekend should trigger a visible growth push across the group.

Sejanus21 # OUTDOOR 2026 | Week 6 — Heat Arrives, Growth Explodes **Day count:** 46 days since germination (May 6) **Date:** June 21, 2026 **Environment (week avg):** 22.8°C avg · 12°C min / 35°C max · 75% RH **Mendocino Skunk + CBDRelax:** outdoors under canopy · remaining four still in greenhouse --- ## ENVIRONMENT & CARE The heat finally arrived, and the plants responded immediately. After weeks of cool, sluggish conditions, temperatures swinging up to 35°C triggered a visible growth spurt across the entire group. Watering daily through the heat, tap water plus Fulvital Plus, supplemented with collected rainwater in the last few days. No active fertilizer this week; the heat stress alone is enough of a variable without adding nutrient on top. --- ## PLANT-BY-PLANT (Day 46) **Mendocino Skunk — 72cm** · The clear leader, with a 20cm jump in a single week. Strong apical dominance is pushing the plant upward hard. A second topping at the new double-top is planned before the move to the garden bed — partly to manage height, partly to push the plant toward a bushier, four-cola structure better suited to full sun in the bed. **Mellowz — 52cm** · Largest plant still in the greenhouse, wide canopy continuing to fill out. **TFC — 46cm** · Strong, well-structured growth following its topping. **CBDRelax — 41cm** · Good recovery and vigorous growth since the topping, now well established outdoors. **Runtz Carlton — 41cm** · Solid growth, deep green color throughout. **CBDelight — 31cm** · Clear growth acceleration since the heat arrived, still the smallest plant. --- ## WEEK HIGHLIGHT The temperature swing from a cool, sluggish few weeks to genuine summer heat made the difference the whole group needed. Every plant logged its strongest week of growth so far. --- ## WHAT'S NEXT Second topping for Mendocino Skunk before its move to the garden bed under the quince tree; done in the next days, with the photoperiod shift still weeks away, to keep stress events separated rather than stacked. Slug protection (Ferramol) to be set around the bed location before transplant. Active fertilization resumes once the heat stabilizes. *Next update: Week 7*

Sejanus21 # OUTDOOR 2026 | Week 7 — Extreme Heat, Explosive Growth **Day count:** 53 days since germination (May 6) **Date:** June 28, 2026 **Environment:** 20–39°C · nights not below 20°C · 72% RH avg **Mendocino Skunk + CBDRelax:** outdoors under canopy · remaining four in greenhouse --- ## ENVIRONMENT & CARE An exceptional week by any standard — temperatures hit 39°C during the day, with nights staying above 24°C. Watering daily at approximately 1L per plant, tap water with Fulvital Plus and occasional Plagron Alga Grow at 1.5ml/L. The heat pushed the plants hard, and they responded accordingly. --- ## PLANT-BY-PLANT (Day 53) **Mendocino Skunk — 85cm** · Second topping carried out on June 25, targeting both new main shoots from the first topping. Despite this intervention three days ago, the plant is already at 85cm and building a multi-branch structure suited for the garden bed. Move to the bed is the immediate next step. **Mellowz — 85cm** · Matched Mendocino Skunk for height — a 33cm jump in one week. The broadest canopy in the group, dense lateral branching throughout. **TFC — 67cm** · +21cm this week. Strong lateral structure developing well — a convincing performance from this new Paradise Seeds variety in its first outdoor season. **Runtz Carlton — 65cm** · +24cm, deep green throughout. The compact node spacing from earlier weeks is now filling out into a well-proportioned plant. **CBDRelax — 64cm** · +23cm outdoors under the canopy. Vigorous multi-branch structure; proving well-suited to full outdoor conditions. **CBDelight — 50cm** · +19cm — the most significant week relative to starting point. The deficit from the Jiffy incident at transplant is now fully erased. At 50cm with multiple lateral branches, it is firmly in the group. --- ## OVERALL ASSESSMENT — END OF MONTH 2 Seven weeks in: six plants, all healthy, no disease, no deficiencies, training complete. The Multicote 6M slow-release depot carried the nutrition through the post-transplant settling period without issue. Topping was executed in two rounds with appropriate recovery time between stress events. The one unplanned incident — slug damage to Mendocino Skunk after its first topping — was resolved the same evening and left no lasting structural impact. The Compound Genetics strains (Mellowz, Runtz Carlton) have adapted well to the NRW outdoor season. TFC as the Ambassador test variety is on a strong trajectory. The CBD strains (CBDelight, CBDRelax) are on course for the volume needed for this season's tincture production. --- ## WHAT'S NEXT Mendocino Skunk into the garden bed; Ferramol to be laid around the planting area first. Active fertilization continues; Calcinit to be added as calcium supplement as plants build toward pre-flower. The remaining five move progressively to full outdoor positions as the greenhouse starts getting crowded.

Sejanus21 # OUTDOOR 2026 | Week 8 — Pest Watch, Growth Continues **Day count:** 60 days since germination (May 6) **Date:** July 5, 2026 **Environment:** 12–37°C · avg 23°C · 70% RH avg **Mendocino Skunk + CBDRelax:** outdoors under canopy · remaining four in greenhouse --- ## ENVIRONMENT & CARE A calmer week after the extreme heat of Week 7 — sunny and dry, but topping out at 37°C rather than 39°C, with a lower average of 23°C. All six plants spent a full day outdoors in the garden under wind and direct sun. The wind emptied the 12.5L Airpots quickly, requiring repeated top-ups with tap water through the day. The first pest signs of the season appeared this week: leaf spotting, small holes, and tiny insects on the undersides of leaves. All plants were treated with neem oil as a precaution. Lower leaves on Tropical Fruit Cake and Mellowz had also started yellowing, so nitrogen was bumped up with 1ml/L Purital E20 on both; the rest of the feeding schedule stayed unchanged from last week. --- ## PLANT-BY-PLANT (Day 60) **Mendocino Skunk — 101cm** · +16cm this week. Still under the canopy, still waiting on its move to the garden bed under the quince tree. Growth hasn't slowed despite two toppings behind it. **Mellowz — 101cm** · +16cm, matching Mendocino Skunk again for tallest in the group. Lower-leaf yellowing prompted the nitrogen bump this week; worth watching whether the new feeding resolves it or something else is at play. **Runtz Carlton — 87cm** · +22cm — the biggest jump of the week. Deep green throughout, no deficiency signs. **CBDRelax — 84cm** · +20cm outdoors under the canopy. Holding its usual self-supporting, low-maintenance habit. **Tropical Fruit Cake — 82cm** · +15cm. Same yellowing lower leaves as Mellowz, same nitrogen response. Otherwise a strong showing for the Ambassador test variety. **CBDelight — 67cm** · +17cm — proportionally the strongest week yet for the plant that started behind after its Jiffy setback. --- ## PEST WATCH Spotting and small holes on the leaves, plus tiny insects on the leaf undersides — classic early signs of spider mites or a similar sap-sucking pest, likely encouraged by the recent heat and dry spell. A full neem oil application went out across all six plants as a first response. Next steps: check the undersides again in a few days to confirm the treatment is holding, and keep an eye out for the fine webbing that would point specifically to spider mites if the population isn't knocked back. --- ## OVERALL ASSESSMENT — WEEK 8 Growth hasn't slowed at all — every plant added 15 to 22cm this week, right in line with the pace since the heat wave started. The two issues that surfaced (pests, mild nitrogen deficiency on two plants) are both minor and were addressed the same day they were spotted. Nothing here changes the season's trajectory; the CBD strains and the THC strains are all tracking well toward flower. --- ## WHAT'S NEXT Mendocino Skunk's move into the garden remains the next major step. Watch the neem oil treatment's effect on the pest population, and confirm whether the nitrogen bump clears up the yellowing on TFC and Mellowz. Calcinit and the Haifa Vitaphos K / SOP phases are still queued up as the plants move toward pre-flower.

Sejanus21 # OUTDOOR 2026 | Week 9 — Moving Outdoors, Strong Gains **Day count:** 67 days since germination (May 6) **Date:** July 12, 2026 **Environment:** 14–34°C · avg 23°C · 73% RH avg **Runtz Carlton + Tropical Fruit Cake:** greenhouse · remaining four outdoors under canopy --- ## ENVIRONMENT & CARE A warm-to-hot week, though without the extremes of late June. Feeding alternated between plain groundwater and groundwater with either Plagron Alga Grow (1.5ml/L) or Fulvital Plus, at least 1L per plant per day. The pest issue from last week appears resolved — no fresh spotting or insects turned up on inspection after the neem oil treatment. The bigger change this week: CBDelight and Mellowz moved out of the greenhouse to join Mendocino Skunk and CBDRelax under the canopy. Only Runtz Carlton and Tropical Fruit Cake remain under glass now. --- ## PLANT-BY-PLANT (Day 67) **Mellowz — 114cm** · +13cm, tallest in the group now that it's outdoors. Lower leaves are still showing some yellowing despite last week's nitrogen bump — worth watching over the next week to see if it clears or needs a further adjustment. **Mendocino Skunk — 108cm** · +7cm, a quieter week for this one. Still under the canopy, still awaiting its move to the garden bed. **Tropical Fruit Cake — 103cm** · +21cm — the standout of the week. A strong response from the Ambassador test variety, still in the greenhouse. **Runtz Carlton — 102cm** · +15cm, also a big jump, deep green and no deficiency signs. **CBDRelax — 92cm** · +8cm outdoors under the canopy, steady as usual. **CBDelight — 74cm** · +7cm, and just moved outdoors this week alongside Mellowz. --- ## OVERALL ASSESSMENT — WEEK 9 Six healthy plants, no new pest activity, and the earlier neem oil treatment seems to have done its job. Growth this week was uneven but all positive — TFC and Runtz Carlton had standout weeks while the others added a more modest 7–8cm, which is well within normal variation given the mix of genetics and positions. The move of CBDelight and Mellowz outdoors marks a shift toward the full-outdoor setup for the rest of the season, with only the two greenhouse plants left to transition. --- ## WHAT'S NEXT Mendocino Skunk's move into the garden bed remains outstanding. Keep an eye on Mellowz's lower-leaf yellowing to confirm the nitrogen adjustment is taking effect. Runtz Carlton and TFC will likely follow CBDelight and Mellowz outdoors in the coming weeks as the greenhouse empties out ahead of the flowering phase.

Sejanus21 # OUTDOOR 2026 | Week 10 — Steady Climb, Decision Points **Day count:** 74 days since germination (May 6) **Date:** July 19, 2026 **Environment:** 18–30°C · avg 24°C · 67% RH avg **Runtz Carlton + Tropical Fruit Cake:** greenhouse · remaining four outdoors under canopy --- ## ENVIRONMENT & CARE A milder week after the heat of late June/early July — a comfortable 24°C average with a top of 30°C, and humidity settling at 67%. No pest activity to report; the neem oil treatment from two weeks back is holding. Feeding continued as before. --- ## PLANT-BY-PLANT (Day 74) **Mellowz — 121cm** · +7cm, the tallest plant in the group. **Mendocino Skunk — 117cm** · +9cm. This one is at a decision point: the plan was always to move it into the garden bed under the quince tree, but with the overall harvest already shaping up generously this season, staying in its Airpot — with the flexibility that comes with it — is now on the table too. **Runtz Carlton — 117cm** · +15cm, the biggest jump of the week. **Tropical Fruit Cake — 116cm** · +13cm, still in the greenhouse and putting on strong growth. **CBDRelax — 102cm** · +10cm, steady as always. **CBDelight — 83cm** · +9cm, proportionally a solid week for the smallest plant in the group. --- ## OVERALL ASSESSMENT — WEEK 10 Six healthy plants, no pest or nutrient issues this week, and growth across the board in the 7–15cm range. With four of six plants now past the 100cm mark, the group is heading toward a size where training decisions — whether to top again to manage the coming stretch, or rely on low-stress training instead — are coming into focus for the weeks ahead. --- ## WHAT'S NEXT Final call on Mendocino Skunk's garden bed transplant. A decision on whether to do one more round of topping (or switch to LST) to keep the stretch phase manageable. Continued monitoring as the plants approach the natural photoperiod shift toward flower.

Sejanus21 # OUTDOOR 2026 | Week 11 — Approaching the Height Ceiling **Day count:** 81 days since germination (May 6) **Date:** July 26, 2026 **Environment:** 11–31°C · avg 19.3°C · 74% RH avg **Runtz Carlton + Tropical Fruit Cake:** greenhouse · remaining four outdoors under canopy --- ## ENVIRONMENT & CARE A normal, dry summer week, though noticeably cooler on average than the last few — 19.3°C average against the low-to-mid 20s of recent weeks. Wind kept drying out the Airpots fast, with watering running to at least 1L a day and sometimes twice. Feeding has switched over to vacation mode ahead of an upcoming two-week absence: alternating plain groundwater with groundwater plus 2ml/L Wuxal Universal, and a separate weekly dose of 4ml/L Wuxal Calcium — a schedule simple enough for a neighbor to follow, and one that suits the tomatoes growing alongside just as well. --- ## PLANT-BY-PLANT (Day 81) **Runtz Carlton — 134cm** · +17cm — the biggest jump of the week and now the tallest plant in the group. **Mellowz — 130cm** · +9cm, tied for second tallest. **Tropical Fruit Cake — 130cm** · +14cm, also tied for second, still in the greenhouse. **Mendocino Skunk — 123cm** · +6cm, the quietest week of the four outdoor plants. **CBDRelax — 115cm** · +13cm, a strong week. **CBDelight — 91cm** · +8cm, steady progress for the smallest plant in the group. --- ## OVERALL ASSESSMENT — WEEK 11 Growth held up well despite the cooler week, with three plants now clustered at 130–134cm. That puts Runtz Carlton, Mellowz, and TFC within striking distance of the 160cm ceiling that keeps the indoor backup option (SanLight EVO 3-80) available if needed — worth addressing before the coming two-week absence, since there won't be anyone around to react if growth accelerates further once the plants tip into the natural photoperiod shift expected in the next few weeks. --- ## WHAT'S NEXT Height management (LST/tying) on the tallest three plants before departure. Continued monitoring of the vacation feeding schedule via the neighbor. Watch for the first signs of the natural flowering trigger over the coming weeks. *Next update: Week 12*

Sejanus21 # OUTDOOR 2026 | Week 14 — Back From Three Weeks Away, Heavy Defoliation Before Flower **Day count:** 102 days since germination (May 6) **Date:** August 16, 2026 **Environment (last week):** 12–34°C · avg 23°C · 65% RH avg (range 28–86%) **All six plants:** outdoors under canopy, moved into open garden during the day --- ## ENVIRONMENT & CARE Three weeks without an update — I was away, and my neighbour and my son took over. The period was hot and dry throughout, with the first two weeks hotter still than the week just gone. The care protocol was deliberately simplified before I left so it could be executed without judgement calls: watering twice daily, Wuxal Universal at one cap per 10L every second day, and one cap of Wuxal Calcium once a week. Bottles were pre-labelled, and the same regime suited the tomatoes growing alongside. It held. All six plants came through without a single loss, no deficiency symptoms, no pest activity, and no heat damage worth reporting. Three weeks of unattended growth in 12.5L and 20L Airpots through a dry spell is a real test of both the substrate mix and the person doing the watering — both passed. --- ## PLANT-BY-PLANT (Day 102, gains over three weeks) **Runtz Carlton — 170cm** · +36cm, by some margin the strongest grower of the group and now the tallest plant in the garden. The mass now sits in the upper third, the lower stem having been lollipopped before I left. This one will need staking before the stretch, not after. **Tropical Fruit Cake — 156cm** · +26cm. The Ambassador test variety continues to impress. Strong apical dominance despite having been topped, a very symmetrical frame, and a deep saturated green. A convincing first season for this variety here. **Mellowz — 154cm** · +24cm, holding the broad, spreading Spritzer habit with several tops of roughly equal strength. No trace left of the nitrogen yellowing from Week 8. **CBDRelax — 144cm** · +29cm — the biggest proportional jump of the CBD pair. Open, elongated frame, still leaning on its support stake. **Mendocino Skunk — 144cm** · +21cm. The double topping has paid off in structure: wide, even, four well-developed main shoots, no single dominant cola. Vital and completely unbothered by the heat. **CBDelight — 115cm** · +24cm. The smallest of the six, but compact and densely branched rather than behind. It has been the late developer all season and is still tracking upward. --- ## LOLLIPOPPING, DEFOLIATION AND POSITIONING All six plants were lollipopped before I left — the lower third stripped out to push energy into the upper bud sites and open up the understory. Today they got a heavy round of defoliation on top of that, targeting the large fan leaves. Two reasons: airflow and light penetration through what had become very dense canopies, and mould prevention ahead of the flowering phase. Humidity peaked at 86% during the reporting period, and from here the nights get longer, cooler and damper — the conditions that decide whether a dense bud finishes clean or not are being set now, not in October. The plants also came out from under the canopy and into the open garden for the day, so light reaches them from all sides rather than one. They go back under the canopy tonight and will keep doing so — overhead protection at night is the single most useful piece of infrastructure in a German outdoor season. --- ## A LABELLING QUESTION Worth recording honestly: I suspect I swapped the labels on the two CBD plants back at the seedling stage. The plant running as CBDRelax has the open, stretched, support-dependent habit of last year's CBDelight, while the one labelled CBDelight is compact and self-supporting — which is CBDRelax's described character, not CBDelight's. Flowering time (roughly 8 weeks versus 8–9), bud structure and trichome density should settle it by harvest. Since both go into the same tincture production, the practical consequence is nil; the documentation consequence is not, so it goes in the log as an open question rather than a quiet correction. --- ## OVERALL ASSESSMENT — WEEK 14 Six healthy plants at day 102, four of them between 144 and 170cm, all through a three-week heat period on a simplified feeding regime and third-party care. That is the outcome I was hoping for and slightly better than I expected. The one number that matters strategically: Runtz Carlton at 170cm has crossed the 160cm ceiling that kept the cellar available as a fallback finishing space. With the stretch still ahead, the four tallest plants are now committed to finishing outdoors under the canopy. That was always the likely outcome, but it is now settled rather than optional, and it puts more weight on support structures and mould management for the rest of the season. Daylength here is down to roughly 14.5 hours. Flowering induction is imminent — first pistils within the next one to two weeks would be entirely on schedule. --- ## WHAT'S NEXT Support structures go in this week, Runtz Carlton first. Feeding shifts off the vacation regime and back onto a proper bloom schedule as the stretch begins — reduced nitrogen, phosphorus and potassium up. No further defoliation for the next two to three weeks; today's round was substantial and the plants need their remaining leaf area to build flower sites. Then a second selective pass around day 21 of flower. Watching for: first pistils, stretch magnitude on the tall four, and any sign of the heavily defoliated canopies bleaching now that they are getting full sun after weeks in partial shade.

Sejanus21 # OUTDOOR 2026 | Week 15 — Flower Has Started **Day count:** 109 days since germination (May 6) · **Flower Day 1** **Date:** August 23, 2026 **Environment (last week):** 9.9–26.9°C · avg 17.7°C · **avg 86.8% RH** **All six plants:** outdoors under canopy, Düsseldorf --- ## FIRST PISTILS ON ALL SIX White hairs on every plant this week. Photoperiod did its job right on schedule — I called it last week for one to two weeks out, and it landed at the early end of that. The weather flipped at the same time. Average temperature fell from 23°C to 17.7°C, minimum down to 9.9°C, and humidity climbed to an average of 86.8%. That is the number that now runs this grow. --- ## HEIGHTS AT DAY 109 (gain over one week) | Plant | Height | +/- | |---|---|---| | Runtz Carlton | 178cm | +8 | | Mellowz | 162cm | +8 | | Tropical Fruit Cake | 162cm | +6 | | CBDelight | 151cm | +7 | | Mendocino Skunk | 149cm | +5 | | CBDRelax | 118cm | +3 | Growth has slowed sharply — 3 to 8cm this week against 7 to 12cm per week during the heat. The cool spell plus last week's heavy defoliation has flattened the curve. For height management that is welcome news: I was bracing for a 30 to 60% stretch on the tall four, and at these temperatures it is not materialising. Runtz Carlton at 178cm is the most critical. Stretch runs for another two to four weeks, so this is not settled. But the trajectory looks manageable. --- ## THE LABELS: RESOLVED I have swapped them. The plant that ran as CBDRelax all season is CBDelight, and vice versa. The habit made it unambiguous — the tall, open, stake-dependent one is a match for my CBDelight from 2025, while the compact self-supporting one is CBDRelax's described character. Anyone reading the earlier entries in this diary: everything up to and including Week 14 uses the old, swapped names. Final confirmation comes at harvest via flowering time and bud structure. --- ## FEEDING — SWITCHED TO BLOOM Wuxal Blütenpracht at 20ml per 10L daily, alternating rain and groundwater. From today I have added Hakaphos Rot at 6g per 10L. Measured EC 1825 µS, pH 6.2. One thing I got wrong: groundwater temperature is 15.5°C. That is too cold going into the root zone, and it throttles uptake — phosphorus especially, which is exactly what the plants need now. Water will be standing to temper before it goes on from here. --- ## LST ON RUNTZ CARLTON — AND A SPLIT STEM Tied the main shoots down today using jute cord anchored to cable-tie loops on the Airpot rim. The pot-rim approach works well and keeps the plants mobile, which matters here since they move between the open garden and the canopy. It did not go entirely cleanly. The stem split lengthwise at a branch fork under the pull. I bound it with jute tape and it does not look serious — cannabis heals this kind of injury readily and usually comes back stronger at the site. In hindsight the fault was mine: I anchored at the fork itself and pulled straight down, which is the one combination that levers a fork apart. Anchoring above the fork on individual branches and pulling out and away would have avoided it. Runtz Carlton has now had lollipopping, heavy defoliation and LST inside three weeks. It is visibly the sparsest of the six. No further intervention on that plant this season. --- ## THE REAL STORY: 86.8% HUMIDITY Flowering onset and near-saturated air arriving in the same week is the worst timing this grow could have handed me. Botrytis needs high humidity, moderate temperature and still air, and I currently have all three. What is in place: the canopy overhead keeps rain and dew off, last week's defoliation opened the canopies up, and lollipopping cleared the understory. Mendocino Skunk has genuine mould resistance in its favour. What worries me is Tropical Fruit Cake, which has the densest, most tightly-packed structure of the six, and the dense CBD flowers. From here it is daily inspection of the bud sites, no overhead watering, morning watering only so nothing sits wet overnight, and enough spacing between plants for air to actually move. If the split stem on Runtz Carlton stays damp under that jute wrap, it is an open wound in perfect fungal conditions — that gets checked too. --- ## OVERALL — WEEK 15 Six plants into flower on day 109, all healthy, height under better control than I expected a week ago, and the labelling question closed. The season is where I wanted it. Everything now depends on the next eight weeks of weather. A dry September and this is a good harvest; a wet one and mould management becomes the whole job.
