Hola 🐎 I never promised you a rose garden....... Day 31 and still only have LST couple times and watered at beginning. Canopy looks flat and nice at the moment. Rose looks beautiful and healthy. Soil NPK was 1-1-1 and looks like there's enough nitrogen still so first watering going to be with bloom nutrients. Spotted first pistils yesterday. With High Medical Hopes 🍀 Running strain: Swiss dream rose auto cbd from KANNABIA https://www.kannabia.com/en/cannabinoids-cannabis-seeds/swiss-dream-rose-auto-cbd

8/15 Yesterday the girls finally got some sun. They're flowering. Like crazy. I do need to do an application of BT once this rain stops. It just started up again. Went back over and things were dry. I decided to hold off watering until tomorrow when I feed. 8/16 Watered the 50 2 gallons, 10 1 gallon, and the rest about 1.5 gallons. I fed a pint to the ten, 2.5 pints to the 30 and 2.5 pints to the FIMMed bluecheese that looked hungry. This way I can tell if they can handle larger doses. I'd like to keep it as small and simple as possible. Gave me a fright this morning when a sheriff pulled in while I was feeding. He was on his way to a neighbors but it looked like he was just admiring things lol. I'm all legals there's no problem there. I put off spraying BT last night because dad had a couple ppl drinking and I didnt want to interact with them. Plus it was to early. The sun hadn't crested the barn yet. At least now u know what time to go spray. I'm finding some lady bugs and I killed my FIRST aphid of the season. I still have caterpillar holes in some leaves though so I might as well hit them with the BT (even though I actively hunt them). No one ever said growing cannabis is easy. Oh and my soil must be BANGING because I found some mushrooms growing in it and like a mycelium web which is awesome. 8/17 This was a quick morning due to an upcoming doctor's appointment. Removed some grass that had grown on the tar from spilt soil as it had diseases on it. I don't want that spreading to my plants. I have one blueberry cheese that I FIMed with four cola's that doesn't have as many leaves and has dropped a few leaves but looking at ot from the other side it doesnt look as open. I know that these girls are transitioning and this is the time I lose leaves. However some plants still seem totally green with no problems despite flowering. I'm wondering if it's a specific phenome thing. I also noticed that the caterpillars are still there and this morning would've been a great time to apply BT but I didn't have time and since I upped the feed I didnt want to do two things at once and have a problem and not know what it is. 8/18 Rained overnight. Plants were soaked. It's not raining now. Plants are definitely overwatered. I'm losing a few more leaves that are yellowing on the bottom interior of a couple plants. Some of it could be from the transition to flower ir the large amount of rain we've been getting. At least my drainage is really good. I need to pull the fence out and co soder cutting a pallet I. Half to better utilize space. I know I say this stuff all the time and I'm not sure it NEEDS to be done. What DOES need to be done sooner rather than later is to apply BT. I can see the damage from them. It's not bad but I want to avoid botrytis as much as possible so those pillars have got to go. Otherwise I've never had plants this healthy and it's been a real ahotty season. Boy those 10th planet's are all mice and green and healthy looking. I'm really looking forward to flowering these strains and see what they can do. I'm already greatly impressed with what I've experienced so far. UPDATE: Wasn't raining earlier then it Rained off and on but just a light steady rain that plants love but it's 3:30 now and it's pouring. Guess I won't be applying BT tonight. We need some sunshine but unfortunately I can't control the weather. Just sitting here thinking I was wondering about using Plant Doctor preventatively just due to the steady rain but I noticed mushrooms growing in my soil and since I haven't not9ced any type of fungal problem I'll revisit that idea another time. Polycarbonate roof or even some form clear plastic and a rough frame of pvc or extra lumber. Theoretically I believe I could move them all indoors for a little bit if need be but that would he a huge pain in the ass. Honestly I've got great drainage and my watering seems pretty good so I might be alright doing nothing. We shall see knock on wood. 8/19 Plants were soaked this A.M. I took a video and uploaded it (which takes forever). It's sunny though today and after the sun comes out after a period of rain the plants grow like crazy. Everything is flowering nicely. I think I can go to the end of October. I talked to a lady today that said she'd already harvested some of her peanut butter breath clones. It's my buddies mom and if you look back at one of my diaries NY mendo breath was done in September. These girls have a ways to go but the are explosively flowering which is good. It's easy to tell which strain is which. Pheno's vary but the flowers on the plants are easy to distinguish from one another. I've also never had plants stay this healthy green this long! Previously I'd have multiple pests, wpm and maybe septoria at this point. I think I've upped my game. Knock on wood. My worst problem now is worrying when to spray BT for the miner caterpillar problem. I have wasps, lady bugs and a shit ton of birds from the 3 bird feeders. I see them dart in and out of my cage. Chances are I'll spray BT tonight and take some pictures if it's nice out. 8/20 The sun is finally out. Bags are still heavy. Looks like it Rained again. I found caterpillar shit so I REALLY need to get that BT applied. I also saw minor damage to a budsite on a low hanging branch. Looks like those fucking earwigs bur I'm probably being paranoid. I also had to remove the rope that I was using to support "the big cheese" because with all this wind and rain it "rubbed" against the stem and caused an injury. I don't need that now anyway with the trellis up. Bids are developing rapidly and stacking up nicely. I have a couple plants that aren't as green as the others bit it may be do to all the rain we've been getting. I think I need to increase the volume of liquid i give my plants when I feed. Next feed I'll be doing at LEAST a quart. Due to my w8fes illness I haven't been able to spend as much time there as I should. No fungal stuff "YET". I have seen some leaves that show the plants have been over watered. Drainage is good though. I forgot to upload the video from this morning and it's uploading super slow so I'm gonna have to upload it tomorrow 8/21 Awesome. Went to town and left without going to my doctors appointment. Good job man. 👏 ANYWAY....My phone was dead when I went to town so I coukd only upload one video. I'll have to do the others later. I mixed up a batch of bt 1 tablespoon with half gallon of water (as that's what this hand mister holds. I went around the cage and sprayed every angle. Then I went to each individual plant and sprayed while spreaking the branches to make sure I got the interior. I used almost the entire half gallon so I'm hoping this will help. Bags were heavy but doesn't take them long to dry out. I'm wondering if the yellowing that is moving up (on the small purple punch and the one in the tote) is because they need more nutes, they're transitioning to flower and really stacking up or because they've been over watered with all this rain. Opinions are more than welcome. I'll check the girls tonight and if the are wet enough I'll feed and at a higher volume. If they aren't ill wait till they get their full water. MY WIFE WAS HAVING AN "MEDICAL PROBLEM AND SO ON THE WAY TO THE DOCTORS I CHECKED THE PLANTS. THE 10TH PKAMETS WRRE DROOPING. I QUICKLY MIXED UP ENOUGH TO FEED EVERYTHING AT LEAST A GALLON AND THEN GAVE THE ONES THAT WERE THE WORST LIKE AN EXTRA HALF GALLON. JUST ENOUGH TILL WE GET OUT OF THE ER THEN I'LL GIVE THEM THE OTHER HALF OF WATER AND ILL FEED THEM. AT LEAST MY WIFE IS OK. UPDATE: Took my wife to the hospital. They did a shit ton of nothing which is par for the course. However, luckily for me (yeah right) I got back early enough to give the plants another half gallon of water each and then I fed increasing the volume to 2.5 pints (upping the big bloom to 3 tsps per gallon) but I ran out of feed on the last plant. I only mixed up two gallons and it was super dark so thar one container plant will need to be fed tomorrow I guess. This is masterofsmeagal signing off to fucking FINALLY get stoned!

The first week of 12/12 light schedule is over and the stretch is on. Most of these plants are getting huge. I gave each plant a 10 gallon flush and fresh nutrients. Upped the maxibloom a little and increased the reservoir volume to 25 gallons since I won't be around to check on them this coming week. I am thinking we should have some pistils popping on the next update. Nutrients are pumping 24 hours a day. Excited to see how these start to frost over the next few weeks.

Think they ain't gonna stretch much now looks ok had to flush soil as she definitely dosent like alot of food light feeds for this strain maybe up It later on using very cheap led grow lights this setup is very cheap but it's for me to see the difference between a perfect setup to a budget setup still has most things she needs good airflow humidity is good can get hot as I didnt invest in ac but nothing over 28c most days they sit at 25c humidity 55% they growing quick even with no feed for 7 days this grow isn't at my home so only see these girls every 48 hours maybe 24 hours I'm feeling to check them day 35 and they stretched like crazy

Ladies and gentlemen week 12 has started day 25 of flower and 83 total as of the 3rd of August.. I just want to say so far she has been an effortless grow and she has handled the heavy feeding I've been giving her as well as the extreme heat that I've been trying to control but I have on an attic apartment with only two air conditioners so it gets to eighty five plus so sometimes I open the tent and I have an oscillating fan pushing air into both hands as I do not have an inline fan with carbon filter due to financial reasons.. anyhow thank you seedsman this has been awesome and I can't wait for my very first CBD one to one especially one with the numbers of potentially 22% THC and 18% CBD that's 40% + TAC .. hopefully I time her chopping perfectly and I get close to that. I hope and pray everyone is healthy and so are their ladies.. good luck to everyone with their plans and happy growing ! I will update if any major changes this week, until then ✌️

Week 1 Report: The White OG - Solo Survivor’s Journey Survivor Status: One Seedling Standing Strong 🌱 Our girl The White OG is standing tall and doing her thing! While some seeds may take their time or not make the cut, this resilient little seedling is already setting the tone. With close to 100% relative humidity (RH) under the dome, she’s got the ideal environment to kickstart her roots and early growth. Environment: Humidity Dome Life • RH: Close to 100%, creating that tropical atmosphere where seedlings thrive. Humidity at this level helps keep her cells hydrated, and with a dome, moisture is consistently recirculated. This prevents her from drying out and promotes steady root and leaf development. • Lighting: For now, we’re keeping the intensity low. At this young stage, seedlings benefit from indirect, gentle light, just enough to encourage photosynthesis without causing stress. Future of Grow LED on a dim setting (200 PPFD) does the job, providing the perfect balance for early growth. Water & Nutrition: Keeping It Simple No heavy nutrients this week; she’s working off the stored energy in her seed. The aim is to keep the soil or Root Riot cube slightly moist but not soaked. Overwatering can drown young roots, so light misting is all she needs to stay comfortable and growing strong. Growth Observations: Slow but Steady Wins the Race Our solo survivor might be growing at her own pace, but that’s exactly what we want! At this early stage, less is more, and slow growth often indicates a strong foundation. We’re looking for stable, healthy roots and tight early nodes as she finds her rhythm. Grower’s Tips for Week 1 1. Humidity Control: Keep RH high but watch for condensation build-up. Too much moisture can invite mold, so allow some airflow if needed. 2. Stay Light on Water: Just enough misting to keep the medium damp. 3. Patience Is Key: Each plant has its own pace; giving her time to establish now sets her up for a strong journey. Next Steps As we move into Week 2, I’ll be keeping an eye out for early leaves (cotyledons) opening up, as well as steady, even growth. Soon we’ll gradually adjust light intensity and start thinking about nutrients. Shoutouts to the Community! Big thanks to Seedsman for the genetics , to Future of Grow for top-notch lighting, Aptus Holland for the reliable nutrients, Trolmaster for total control and everyone in the growers’ community cheering on this solo survivor. 🌱💪 Growers Love! 🌞 and here’s to a strong start for the future of this grow! 🌱 DISCOUNT CODE - SeedsmanSeeds - DOGDOCTOR 10% off As always thank you all for stopping by, for the love and for it all , this journey of mine wold just not be the same without you guys, the love and support is very much appreciated and i fell honored and so joyful with you all in my life 🙏

🌸 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.
