1/25 Week 11 Ripley : Flushing begins with a five gallon flush to move the runoff to under 200ppm and defoliated by pulling almost every leaf on a stem, and god what a bunch there were. This opens the plant and removes those sources of nuets. Going to doing this as quickly as we may so will be monitoring runoff as we go. Tara: Slight Defoliation just trying to keep these leafy SOBs open. Back on Heavy dose of CocoTek and placed in best light I can we just watching the bud growth for how to help this big girl. Will not pick up Peak again until ready to withdraw the CT. Better pics when I can 1/26 Ripley : Second day of flush just keep running water through it till runoff gets low no longer PHing the water, nothing much left in there anyway. Fading really showing now Tara -Zilla : She likes the nuet and light change buds really building now Not getting any taller 1/27 New pics of Ripley she is getting so damn frosty in flush Tara building buds very quickly 1/28 Continuing flush on Ripley, she will be harvested in two days, its fast but we need the space. Tara no changes except more buds 1/30 Ripley removed from tent for harvest. Opened up Tara's binds. Tara now the Queen of all she surveys... All hail Queen Tara The Beast ! 😜 *****RIPLEY HARVEST DAY !!!!! ***** Pics up top Wet weight - 1,140 grams 40.7 Ounces Just looking at it we be lucky to only lose 75% in dry but still not bad! Not a pleasant job trimming - LOTS of leaves UPDATE 261 grams dry, yeah took a beating on the dry but expected it.

Now Milky Dreams is starting to fade as well even though it looks like a deficiency might play into it as well imo but I'm not quite sure. At this point I can only repeat myself when saying that they look amazing

Day 42 - Kinda crazy how fast it's gotten to be day 42 (the meaning of life - *) in the grow. Haven't watered yet. Plan on doing that with the above nutrient schedule tomorrow or the day after. And I think that might be the last time I give any nutrients to the plant. Pistils are beginning to curl, and I've seen (just a few) amber tirchomes on one bud. I want to harvest on the earlier side because I don't want this harvest to have a big couch-lock effect. Prefer a more cerebral high, although some bodily relaxation is nice too. So I think I will be harvesting at the latest by April 10th (Day 56). Of course I will continue to watch how the plant develops and if no further trichomes are turning yellow/brown in a week, I'll wait longer. The trichomes on the sugar leaves have a wonderful lemon citrus smell by the way. Not what I was expecting, but that's fine 😛 Day 45 - Made a video of the trichomes. They definitely look cloudy enough to me. No more nutes for sure, harvest in 10 days max I think.

Trying to dial their veg in. Nutes may be too old or too high. Changed with 4ml CaMg per gallon of RO water. The rest is MaxiGrow. Ever since adding rockwool to the grow, I have struggled. I don't have the dry back timed right yet. I moved my fan to dry the top of the pot surface instead of in the root zone or at the canopy height. After about 10 days I dumped out the rockwool and have replaced with hydroton. My initial though on using rockwool was to give the roots more space during late life stages. My experience has been with hydroton and I notice that the roots eventually get bound because the hydroton is a durable material and will not crush or compact. Rockwool on the other hand will compress when squeezed so I was hoping that in the late life stages the roots would compress the rockwool and make more room in the pots. The issue was dryback. If I used chunks instead of croutons, this may help but the other reason I used them was because I had them here already. If anyone is trying to slow their dryback down, they should consider adding 10% volume of croutons to hold moisture in the medium a bit longer. Notice anything different? They are starting to adapt to their new media. Hopefully by next week I can get them to perk up. One plant has looked better than the other three. I have no idea what these plants need to “perk up”. Possibly a different grower. If a grape terpine wasn’t in the end results I would have culled these long ago. Hopefully they perk up when we get to flower. 3 look ,,,, meh, the fourth is descent. Trimmed all four back down to 12” tall. Flower next week.

Very good week. The new plants are 24 days old. That’s how they are supposed to look at that age! They will be much bigger plants than the others because all was dialed in for this new batch. With autos there can’t be anything off or they won’t really get to big (typically). The older plants 6-8 weeks old - will be excellent smoke still just not as big as they can get. Start of week 9. The smaller plants are 31 days old. All looking very very good. I upped the cal/mag The TD and LS will harvest in around 3weeks. I always run them close to 1-2 weeks past recommended. They really frost up and gain weight the last 2 weeks. Excited about the new plants. When they are dialed in I’ve gotten 3-7 Zips from each plant. Pretty amazing for soil grow. Hydro is faster in the beginning and sometimes the entire grow but soil when all on point can keep up with hydro (after a few weeks) and lots of time surpass hydro. Definitely in taste and terpenoids. Happy growing! Any comments appreciated. I love learning about this wonderful plant!

🌸 White Widow — Week 7 Flower (Week 11 from seed) Status: Full flower, bulking rapidly. Vibe: Dark foliage, compact form, heavy frost, 90s aroma profile. Feeding: Aptus + Plagron lineup (Power Buds, Sugar Royal, Green Sensation, Regulator, CalMag, All-in-One) Photos: Sony a6000 — loyal workhorse for studio shots. 📷 ⸻ 🧠 Deep dive — Why 12/12-from-seed makes a plant “go hard” Plants evolved to reproduce. Their primary biological drive is to make seeds. Photoperiod (day length) is one of the most reliable seasonal cues plants use to decide: is it time to flower? Mechanisms at play (simple → nerdy): • Photoperiod sensing: Leaves detect day length via phytochrome systems (Pr Pfr). Short days (or the 11/13 rhythm) flip the hormonal cascade toward flowering. • Florigen & flowering hormones: When the plant senses “short days,” it produces mobile signals (florigen) that travel to the shoot apex and shift gene expression from vegetative growth to reproductive development. • Carbohydrate reallocation: Energy stops making more leaves/branches and is directed into calyxes, resin synthesis, terpene pathways, and seed/flower tissues. • Result: A plant that thinks “the season’s ending — reproduce now!” goes all-in: denser flowers, rapid calyx swelling, intense trichome production. Important point: they don’t know about pollination. The plant can’t tell you whether pollinators exist or whether pollen will land — it simply invests in attractive, resinous flowers to maximize reproductive success. As growers, we exploit that drive to produce potent sensimilla (unpollinated) flowers. ⸻ 🔬 Why your White Widow is exploding in quality right now • Immediate reproductive programming: Starting floral signals early (12/12 from seed) forces the plant to prioritize flower formation rather than vegetative mass. That yields compact, dense colas. • High PPFD + short day = strong DLI in less time: With fewer hours of light, your lamp intensity is higher in those hours → powerful photosynthesis during the window the plant has chosen. • Nutrition tuned to flower: the Aptus + Plagron stack feeds the metabolic surge — PK + biostimulators for bulking, sugar stimulators for terpene pathways, Ca/Mg for structural health. • Genetics: White Widow is resin-happy; give it the right cues and it will frost up like a sugar cookie. ⸻ 🌈 Why her colors are going dark (and why that’s beautiful) Leaf & bud color comes from a balance of chlorophyll + accessory pigments (anthocyanins, carotenoids) and is influenced by: • Genetic propensity (some phenos are naturally darker) • Temperature swings (cooler nights often increase anthocyanin expression) • pH / nutrient balance (some deficits/ratios nudge color pathways) • Light spectrum intensity (strong red/far-red influence can shift pigment expression) Dark phenos often correlate with high terpene and anthocyanin expression — visually stunning and often highly aromatic. ⸻ 🔁 Quick timeline recap (for newcomers) • Germination & early mistakes: initial heat-mat loss → restarted, one strong survivor. • Veg: compact, short internodes under the 11/13/12-12 shuttle → stacked nodes. • Early flower: slow to show, but once she flipped she committed. • Now – Week 7 flower (Week 11 from seed): heavy bulking, thick trichomes, deepening color, classic White Widow aroma emerging. ⸻ 🔭 What to expect next (this week → next week) Expect: • Continued bulking of calyxes and cola weight. • Explosion of trichome coverage — white, cloudy glands multiply. • Stronger terpene smell (earthy, spicy, resinous 90s profile). • Possible color intensification — deeper greens, potential purples depending on phenotype & nights. Do not expect: • Major new stretch — she’s committed to flower and will remain compact. • Immediate harvest — typical White Widow still wants its weeks; plan for patience (mid-late flower bulking happens over several more weeks). ⸻ ⚖️ Should you run all seeds 12/12 next cycle? (pros & cons) You asked if you might run every seed 12/12 — here’s the honest rabbit-hole: Pros • Much faster cycle → less time to harvest. • Compact plants → ideal for small spaces or stealth grows. • Often denser single-plant yields; less training needed. • Great for experimentation, multi-strain rapid rotation. Cons • Generally lower total biomass per plant vs. long veg runs. • Some genetics need veg time to express full canopy & branching; yields may be lower for those strains. • Root systems can remain smaller → may stress under high PPFD if not supported. • Less flexible for heavy-topping/lst/manipulation strategies. Bottom line: for strains with good genetics for flowers (like White Widow), 12/12-from-seed can be very rewarding. For sativa-dominant, tall strains you might lose yield without long veg. ⸻ 📷 Gear love — Sony a6000 shoutout I’ve got to echo it: that camera is a workhorse for growers. Compact, responsive, great color fidelity, and perfect for low-light studio shots when paired with proper exposure. The a6000 captures the leaf texture, color depth, and bud gloss in a way phones struggle to match. Long live the loyal shooter. 📸✨ ⸻ 🙏 Gratitude — the usual and the real Thank you to: • Zamnesia — for the genetics & the nostalgia. • Aptus & Plagron — the chemical & biological push that lets the plant sing. • ThinkGrow / Future of Grow / TrolMaster — lighting, control, and environment orchestration. • You — the makers, lovers, critics, curious readers — your energy fuels this diary. And to our White Widow — for showing up, forgiving mistakes, and giving back in beauty. 💚 ⸻ Week 7 flower — Week 11 from seed. Darker colors, heavy frost, the classic 90s scent, and a compact structure that proves 12/12-from-seed can produce absolute fire. We went full-in on Aptus + Plagron, kept the Emerson red-lead sunrise/sunset, and trusted the genetics. Watching her build is pure joy.

Be a giver, and the universe will give back in ways you could never imagine. 💚 Growers love to all P.S. — Deep dive on DLI (Daily Light Integral) — short, clear, and a little nerdy (in the best way). 🌞🌿 1) What is DLI, simply? DLI = the total amount of photosynthetic light (photons) a plant receives over one day. It’s expressed in moles of photons per square metre per day (mol·m⁻²·day⁻¹). While PPFD (μmol·m⁻²·s⁻¹) tells you instantaneous light intensity, DLI tells you how much light the plant actually used that day. ⸻ 2) The formula (how to calculate it) Use this exact formula: text{DLI (mol·m}^{-2}text{·day}^{-1}) = frac{text{PPFD (μmol·m}^{-2}text{·s}^{-1}) times text{seconds of light per day}}{1{,}000{,}000} Where seconds of light per day = hours of light × 3600. I’ll show worked examples so it’s easy to follow. ⸻ 3) Worked examples (digit-by-digit so it’s crystal clear) Example A — your reported PPFD ≈ 766 μmol·m⁻²·s⁻¹ and 11 hours light • seconds of light = 11 × 3600 = 39,600 s • photons per day = 766 × 39,600 = 30,333,600 μmol·m⁻²·day⁻¹ • convert to moles: 30,333,600 ÷ 1,000,000 = 30.3336 mol·m⁻²·day⁻¹ So: 766 μmol·m⁻²·s⁻¹ × 11 h → DLI ≈ 30.3 mol·m⁻²·day⁻¹ Example B — same PPFD but 12 hours • seconds = 12 × 3600 = 43,200 • photons = 766 × 43,200 = 33,091,200 • DLI = 33,091,200 ÷ 1,000,000 = 33.0912 mol·m⁻²·day⁻¹ Example C — other quick refs • 700 μmol × 11 h → DLI ≈ 27.72 • 800 μmol × 11 h → DLI ≈ 31.68 • 400 μmol × 11 h → DLI ≈ 15.84 • 1000 μmol × 12 h → DLI ≈ 43.2 (You can plug any PPFD and hours into the formula — those are ready-made reference points.) ⸻ 4) What DLI targets are useful for cannabis? • Vegetative (gentle): ~12–25 mol·m⁻²·day⁻¹ • Flower (typical good range): ~25–40 mol·m⁻²·day⁻¹ — most home/pro growers aim here • High-intensity/CO₂-enriched commercial: 40–60+ mol·m⁻²·day⁻¹ (needs CO₂, stronger conditioning) So your example (≈30 mol·m⁻²·day⁻¹ at ~766 PPFD × 11h) sits very nicely in the flower range. That explains the dense bulking + heavy resin you’re seeing — our DLI is right where White Widow loves to convert energy into flowers. ⸻ 5) Practical implications — what DLI affects and what to watch • Higher DLI → higher photosynthesis → more carbohydrate to drive bud bulking and terpene/trichome production. • Higher DLI requires more water and nutrients. Plants transpire more and pull more minerals; be ready to feed and irrigate appropriately. • Leaf temperature / heat stress: pushing PPFD up increases canopy energy/heat — keep airflow, VPD, and room temps under control. • CO₂ matters: if aiming beyond ~40 mol/day, elevated CO₂ (e.g., 800–1200 ppm) becomes productive; otherwise additional light won’t be used efficiently. • Distribution matters: DLI is an average over the canopy. Hotspots or shaded pockets mean some flowers get too much or too little — even light spread (and PAR mapping) matters. ⸻ 6) Actionable tips for your run (based on your 11/13 / 12/12 experiment) • We’re hitting excellent flower DLI (≈30 mol/day at 766 μmol × 11 h). That’s why buds are dense/frosty — keep the rhythm. • If you shorten hours (e.g., 11 h) keep PPFD high to maintain target DLI. If you lengthen hours (12 h) you can reduce peak PPFD slightly and still hit the same DLI. • If you raise PPFD to chase more DLI, ramp slowly (a few μmol/sec per day) to let stomata and roots acclimate — avoid sudden bleaching. • Watch watering & EC — higher DLI → faster uptake → more frequent but measured feeding. • If you ever push DLI 40 mol/day consider CO₂ enrichment and perfect VPD control to have that extra light used efficiently. ⸻ 7) Quick rules of thumb • Want to hit ~30 mol/day with 11 hours on the clock → aim for roughly 700–800 μmol·m⁻²·s⁻¹. • Want ~33 mol/day at 12 hours → ~766 μmol·m⁻²·s⁻¹ matches that nicely. • If you see leaf cupping/bleaching, you’ve likely exceeded safe PPFD for that canopy or temps are too high — back off, check VPD.

So Woche 6is angelaufen und ich entschuldige mich schon mal in Woche 5 nichts an Bildern hochgeladen zu haben. Hab jetzt die 2 hinteren Sapphire scout zum 2ten mal getoppt die vordere davon nur 1x bei den rqs zz is bis jetzt nur die hintere 1x getoppt und die beiden vorderen noch garnicht hoffe die beiden kann ich wenigstens einmal toppen die machen mir echt Sorgen vorallem die am Anfang stehende zz is recht krüppelig ich denke mal das die wurzeln nicht richtig durch die jiffies kommen (netzt nicht AUFGELÖST) würde in Zukunft die scheiss Dinger weg lassen und mir kleine durchsichtige getränkeflaschen zerschneiden um daraus anzuchtopfe zu machen dann fällt das netz weg und es gibt wohl weniger Sorgen nächste Woche lass ich mein scrog netzt drauf um das ganze zu begrenzen und hoffe das dann die rqs samen noch aufholen können

Apollo F1 had to come down due to bud rot. These videos were taken n June 10 and at that time no bud rot was visible. We've had so much rain this spring season with limited fully sunny days. I harvested June 14. The main cola was full of bud rot. That's how fast it can spread.

Note : Jegliches Equipment aufgelistet welches ich nutze findet Ihr in der Germinations Woche !!! Day 15 : ich weiss noch nicht ob der mineralische dünger wirklich sofort etwas gebracht hat . schauen wir was die zeitraffer so vermitteln. ist es seit gestern schneller am wachsen ? Day 16 : PPFD 275 * 20h = DLI 19.8 Day 17: + 0.5L Flaschenwasser (EC 0.26) + + Canna Rizothonic + + Canna Terrar Vega + = Total EC 0.68 (PH 7.2) + Final PH 6.15 Day 18: es wächst Day 19: es wächst immer noch ventilation übern blätterdach angemacht. ich glaub daher kommt das ruckeln im video Day 20: + 0.5L Flaschenwasser (EC 0.26) + + Canna Rizothonic + + Canna Terrar Vega + = Total EC 0.68 (PH 7.2) + Final PH 6.15 + 0.5L Leitungswasser (PH 8.0) Der Stamm hat sich in den letzten 3 Tagen verdreifacht vom Volumen. Jetzt hat er so Bleistift dicke erreicht. Day 21: die temps und relative luftfeuchte sind hier zwischen 58%-68% und 23.5°-25.5°C . reguliert sich aber immer zu den höheren werten . ist hier halt so :))

British Delight - Wizard Trees Day 77 - Watered with 3L of RO tap water with nutrients, mixed individually, in order and then pH'd to 6.3! Week 6 of flower and she's growing good, she's very bushy so I had to remove a lot of foliage from her, especially at her canopy level, as it was blocking the whole plant from receiving sufficient light 😅 as a result, she's the shortest plant in the tent, so she'll have to be raised up to meet the rest of the canopy - let's hope she starts bulking fast now 🙏🏻

This week didn‘t started really well. There were big rainfalls all over germany but especially in my region. I had the plants in the greenhouse so they were safe but after days of rain the water started to drip into the greenhouse. I tried to keep the plants in dry spots but just saw that one of my plants had mold in her flowers. I immediately cut the piece with mold off to keep the rest of the plant safe. As I removed the leaves from the buds I carefully looked all over the buds and cut the mold and the area around it off. I also cut all the buds off the stem and will dry them seperated from each other and not hanging on the stem like last time. This way the risk of another mold infection after the harvest is lower. The next bad news is that the Painkiller looked really sad. Lower leaves were turning yellow or white and the leaves were hanging down. I decided to remove some big fan leaves and to cut off the yellow and white small leaves. Then I watered her good and gave her some self made nutrients out of nettles. In the evening the plant already stood straight again and looked good!

This plant was very easy to grow and had a Fantastic Yield.. The aroma smells just like paint thinner, The flavor on inhale is sour/fuel and cathedral incense on exhale..It's all head buzz w/o paranoia .. I also pulled 9 grams of hash & 3.7 grams shatter/wax(not counted in weight) from trim & leaves-no buds.💪🙏👊😍😘

Day 5 since time change to 12/12. Hey everyone ☺️. Finally the time has come :-) The lady moved into the flower tent on January 6th, 2021 😁. The day before, of course, a cutting was taken 👍. In the flowering tent, the distance between the plant and the lamp is 40 cm so that she can get used to the strength of the lamp. After 3-5 days I go down to 30 cm. This week it was watered twice with 1 l per plant. GHSC enhancers were added to one wash :-). Flower fertilizer will only be added in 12-16 days as soon as the first blossoms are there :-). Otherwise the tent was completely cleaned and the humidifier refilled. For the next few days I have filled fresh osmosis water in canisters again :-). Next week I will remove the bottom shoots so that the energy doesn't end up going into small popcorn buds 😉. There is nothing more to report this week and I wish you all a lot of fun with the update 😀. Stay healthy and let it grow 🙏🏻🍀 You can buy this Strain at : https://sweetseeds.es/de/red-mandarine-f1-fast-version/ Type: Red Mandarine F1 Fast Version ☝️🏼 Genetics: Red Poison Auto®️ (SWS39) X Tangie (California Orange x Hybrid Skunk) 👍 Vega lamp: 2 x Todogrow Led Quantum Board 100 W 💡 Bloom Lamp : 2 x Todogrow Led Cxb 3590 COB 3500 K 205W 💡💡☝️🏼 Soil : Canna Coco Professional + ☝️🏼 Fertilizer: Green House Powder Feeding ☝️🏼🌱 Water: Osmosis water mixed with normal water (24 hours stale that the chlorine evaporates) to 0.2 EC.
