Another good week!! I defoliated the smaller of the 2 plants mid-week... I think she is doing very fine. A small hiccup with the feed that same night. Only a few leaves are showing any sign on nutrient burn. I went ahead and fed them again today. I plan on watering them in a day or two... they were very thirsty this afternoon!! So, I definitely need to up the watering. I've still been feeding 3 quarts twice a week. Otherwise, all seems to be going well!! They are frosting up very nicely!! So exciting!! Peace!! Update for grow question: @The8thChevron thanks!!! I pulled them and will hope for the best for now. So close to the finish line. If I see more trouble brewing I will pull the plant. I don't know how to answer directly to you on the grow question.... Thanks again!!

6/15. Glad I listened to my intuition and held off watering. IT Rained andctheb again last night. Plants seem to be doingvreal well. Slight burn on lower leaves where it was before from being in the garage and I found on spot that LOOKED like it could've been caused by a pillar but it's right on a burn. I sefoliated one leaf. This is minor stuff. Next watering I'll be adding silica. I'm not giving nutes until the plants tell the need them. The 3 gallon ones may receive nutes first as they'll run out. I'll update as I progress. Went back over at 8:30. It's just overcast with showers. Plants seemed to like it. They all look good. Noticed a chunk out of a leaf and a POSSIBLE pillar spot. I'm going to have to get the BT out and and give the girls an application. I'm waiting until they settle in a bit more though. I need to start LST as well AND the light dep. Unfortunately "life" has made things difficult. I'll get back over there today though and I'll start the light dep. Kinda makes me wonder though. The 1pth planet I wanted to light deo is tge same size as the others in the much bigger containers. The thought came that maybe I should just hold on to them as extras in case something happens. I also am going to start silica next watering but it will be a few weeks before any nutes are given. UPDATE: WENT BACK OVER AT FIVE AND TOOK ACSHOT TON OF PICTURES. IM TRYING TO UOLOAD NOW. THINGS ARE POPPING OFF AND IM GETTING A NICE SWEET SKUNKY ODOR. WHILE I WASCTHERE WE GOT A QUICK SHOWER. DIDNT LAST MORE THAN TEN MINUTES BUT IT RAINED HARD. I FOUND A TEMPORARY SPOT TO LIGHT DEP THE TWO PURPLE PUNCH AND THE ONE TENTH PLANET. I DONT SEE ANY LIGHT LEALS AND ITS SURE AS HELL DARKER THAN IT IS AT NIGHT. I'LL SEE HOW IT GOES LEQVING THE COVER ON ALL NIGHT. IF IT DOESNT WORK I MAY JEED TO ADD A FAN OR CHANCECTHE SPACE. I ALMOST DIDNT WANT TO DO THIS AS THE 10TH PLANET IS KEEPING PACE WITH ITS SISTERS, DESPITE THE SMALLER POT. OH WELL I WANT TO GIVE IT A SHOT AND I DONT WANT MY CAGE OVER CROWDED. I'M LOOKONG TO DO A 6:30 TO 6:30 SCHEDULE. 6/16 First night of light dep for the three little ones. I won't be able to call them that soon. I'm currently trying to upload a video. My grow buddy mentioned the droopiness of a couple of my plants in this video and how I hadn't been watering. This kinda scared me so I ran over and checked the too few inches on the two that had a little droop and came out dry. I had some water already phed ready to go (I'm hoping that the ph doesn't change if it's stored a day or two) and used the gallon to moisten the dry topsoil. Looking back over my diary we have had nothing but rain. I then tried the "lift the pot method" and came to the conclusion that these bags were indeed still holding moisture. I assumed they would be considering the thunderstorms we've had. I held off on fullt watering because the weather said the next dry day is going to be Monday. Today is Friday so thats two solid days of rain. Three if you count today through the night. I concentrated my watering of the one gallon on the couple plants that appeared to droop. If it doesn't rain like they say it will I will need to water. I need to set up a decent watering schedule but I need it to hold off raining long enough to do so. UPDATE: I WENT BACK OVER AND PUT THE 3 GALS IN FOR BED AND CHECKED OUT THE REST OF THE GARDEN. I WATERED THE 3 GAL GIRLS A LITTLE MORE SINCE THEY WONT BE OUTSIDE. THE BIT OF WATER I GAVE SEEMED TO HELP LIFT SOME OF THE GIRLS. AT LEAST I THINK IT DID. THE RAIN SHOULDVE COME ALREADY. I WOULDVE WATERED MORE HAD THE BAGS NOT BEEN SO HEAVY. 6/17 Rained all night which is good. Brought the three transplants out but left them under the overhang so they. Dont get soaked. So far light depoing is going good. Well its only been two nights but we'll see. I'll update as I go. Not feeling well today. Went back over and checked on the plants and did a video. Probably won't get uploaded until tomorrow. I'm giving it a shot. It's raining in good shape. Plants looked fine when I was there. I need to get my supports and my trellis in place. Video won't upload. No suprise. I'll get it tomorrow. 6/18 Uploaded videos if they fuck up from me editing I'm gonna be pissed. Anyway it's still pouring with high winds. I added a couple supports where it looked like it needed it. I need to put my trellis up. I've been able to keep up with the light dep and those plants haven't been used and abused. They stay in the building facing the sun when the weather is this bad. I think they're looking great. I may start a new diary just for them. Sun came out around four. Trying to upload a couple videos but doesn't look like it's going to happen. Tucked the three little ones in at six. It had stopped raining and the wind died down some. If adverse conditions create good plants then I'm on the way to a great harvest. Minor bleaching and burns on a few lower fan leaves and some wrinkling on some from wind burn other than that plants seem to be acclimated. Did a video but will have to wait until tomorrow to upload 6/19 It's not raining! We got four inches this past storm lol. Having the bags raised on pollens I believe has greatly helped. As did the high winds that help dry the soil in the bag. Had to add a few temporary supports. Light dep is going good. Adjusted amd found a better spot. I'm considering getting "pool noodles" or some other thing like a Hulu hoops or pvc pipe and making either a frame on the roof for the entire cage or on top of each individual plants posts so I could roll clear plastic over it when it rains. I'm thinking about later on in the fall when this could really help. I found a roll of plastic. Also thought about putting that up on the back wall but I didn't. What I'm doing right now is working. I just need to keep up with it. I also need a solid watering schedule to stick too. It's hard when each plants needs are different. Oh well. I'm just happy to be growing again. I pray to the cannabis gods and the Lord above himself that I'm not plagued with the problems of last year. 6/20. I'm sick as fuck but I got the little girls out in the sun. Light dep is going good. Plants look great. I'll update when I feel better and if I do anything. Still feel like shit. Luckily I looked up just in time to get to the grow and put the little ones to bed. They were thirsty (especially the bushy 10th planet so I gave them about 3/4 of a gallon of water. Got lots of run off from 10th planet. Didn't notice as much from the others but I was hurrying. I'll upload later. Still sick. 6/21 Plants seem to be doing great. I removed some lower growth on a few just to see how they respond. I'm going to do some defoliation down low and I want to see how the plants respond. I'm planning my first full watering Thursday as we have a real good stretch of weather after that. Grow bags are still heavy as hell so they have sufficient water. I'll be adding silica nextcl watering. Not time for nutes but I think it would be okay to start the silica and in another week I might start small doses of nutes. The light dep on the little girls is go8ng great! It's cool I'll get to sample some of these strains before fall. I'll update after I do something. Tucked the girls in at 6. I might need to think about transplanting that 10th planet in the 3 gallon. I watered until runoff yesterday and it's light as hell today. Plus I fimked it and it's bushy as hell. I've Bern turning it si it gets all angles of the sun. I have a bag of 707 left and a 5 gallon bucket with holes drilled all over it like an air pot and a ten gallon grow bag. This will take some thought. Hot af today. I wad able to lift the grow bags so I decided tomorrow will be the girls first real watering. I think I'll be adding silica and possibly kelp me kelp you due to the heat stress I've been noticing. Nothing bad just a few tacoed leaves. I've had several people that have seen my grow in person tell me that this is by far the healthiest (not biggest I've had bigger) but by farcthe healthies5 crop I've grown. They believe I'll have my best year ever this year. I hope they are right. Vid won't be uploaded until tomorrow. 6/22 WATERED TODAY. I'm still a little gun shy with watering. That fusarium last year pretty much traumatized me. I left the container plants alone. I gave them a little water but not enough to do much. I used a pump sprayer on a mist setting and went one by one and back around gently watering the entire medium. This took forever and I'll be finding a different way to water. I hope this was enough water. I'll check later on and if they look like they want more I give it to them. I started LST on the light dep 10th planet and tucked some branches of a another under the tomato cage. I had missed that earlier. I also went around and cleaned up the bottoms on most. Getting rid of things that will amount to nothing. I noticed what looked like thrip damage on ONE leaf on ONE plant. I also saw a chunk missing from a grasshopper bite and a finger of a fan leaf petiol was broken so I'm going to need to get my ipm up and running. I'm unsure whether I'll be using chemicals or predators. Probably BT and spinosad. That's what I've had the best luck with. I also noticed bottom leaves dying off on the bottom of a couple plants. It was where the burns were though so I'm almost 100% its just related to the light burns they got when i first put them up. I'll be updating the diary as I do more stuff.

2 weeks into the growing season. Things are going well, starting to apply LST to some plants. I have also started to remove little by little those leaves that interfere with light penetration. Bruce Banner unfortunately turned out to be retarded in development, but I won't remove him, in my experience, retarded people often turn out to be very strong ^_^

Vamos familia, actualizamos la sexta semana de crecimiento de estas Terp & Tonic de Seedstockers. La temperatura que estuvo entre los 24-26 grados y humedad dentro de los rangos correctos. Esta semana ya cambiamos a 12 horas luz,12 horas de oscuridad, estiraron bien y ensancharon bastante también, el color es verde sano. Se nota que los nutrientes de la marca Agrobeta hacen sus funciones. También realicé una poda de bajos que yo si las veo necesarias para explotar después la flor. - os dejo por aquí un CÓDIGO: Eldruida ,descuento para la tienda de MARS HYDRO. https://www.mars-hydro.com Hasta aquí todo, Buenos humos 💨💨💨

🌱 Week 3, Day 7 Update: Buds Are Blooming! 🌿 Hey Grow Fam, We're cruising through Week 3, and my girl is really coming on—buds are starting to form, and it's a sight to behold! The girl is growing so fast now, drinking 4.5L a day. She could even do with in-between waterings, in my opinion. She's aiming for the stars and shooting for the moon, getting bigger every day and stinking out my room. I had to tie my light higher up with some rope as it wouldn't go any higher, and shoots were getting way too close! I did SCROG when flipping, and I should've been a bit more strict on it (did it longer), but now I realize why SCROG is used. Imagine if I never used it—she would be way too tall. Overall, I'm so happy with how she is growing and can't wait to see the final product. :) But, as with any journey, we've hit a little bump in the road. Despite keeping our feeding consistent at 850ppm, the runoff readings have been creeping up. Last check-in showed a runoff of 1400ppm. It's got me thinking we might be dealing with a salt buildup in the root zone. To address this, I'm sticking with our feeding routine at 800-850ppm. If the runoff ppm keeps climbing or if our plants start showing signs of nutrient burn, I will adjust accordingly, but as of right now, I'm sticking to the same feed as she looks great! ( If I do begin to notice signs of nutrient burn (excess), I will try to water with a lower EC/PPM, like 700ppms, to bring it down. But if I don't get the results I'm hoping for, I will just flush the plant with 3x the media size of water (just plain pH water) to wash out any old salts and reset the medium. You don't really want to do this with coco depending on what stage your at in flower, veg on the other hand flush.? Sure!, if you really need to reset that medium go for it, (i do see tiny signs of burn but thats fine if it gets worse then i have a problem) Let's stay focused and keep our eyes on the prize—beautiful healthy buds. We've got this! #GrowUpdate #Week3 #BudsBlooming #KeepGrowing 🌱🌿

Everything is good without any problems for now. One plant seems like the leafs are sightly burned 😰 but it did'n get worse in past few days and it grows healthy so i think it will look better next week 💪 Today is day 7 of the plants, yesterday i transplanted them into the main 15 liters pot with organic soil mix 👌 Today i also added some Voodoo Juice from AN to help the roots involve. They say it is good for organic gardens and i got it from one of my past grow. Stay Blessed with sacred plants 🙏 May start some new diary with different seeds, but same growroom soon 👋 I almost forgot, my photoperiod is 12-1 thats why my plants have only 13 hours of light every 24 hours. For me it worked perfect in the past, if you want to read more about this photoperiod https://theweedbusiness.com/12-1-method/ here is some short explanation. Less energy waste 🙌 and organic product is a different level for me 😁

Correct Math - 185w * 56 days of veg (18h) - 390w * 70 days of flower (12h) - 46g dry material - Total space around 37.5% of the tent Veg cycle: 185w / 1000 = 0.185 kW/h 0.185 kWh x 18 hours per day = 3.33 kW per day 3.3 kW per day x 56 day veg cycle = 186.48 kW per veg cycle for the whole tent 186.48 * 0.375 = 69.93kW for the area covered by the plant Flower cycle: 390w / 1000 = 0.39 kW/h 0.39 kWh x 12 hours per day = 4.68 kW per day 4.68 kW per day x 70 day flower cycle = 327.6 kW per flower cycle for the whole tent 327.6 * 0.25 = 122.85kW for the area covered by the plant Total: 69.93 kW (veg) + 122.85 kW (flower) = 192.78 kW per entire cycle for the area covered by the plant 46 grams dried / 192.78 kWh = 0.23 grams per kW --- Total Harvest Total Harvest = 11g Choco + 66g KDA + 46g BC = 123g Total kW = 186.48 + 327.6 = 514.08 123g / 514.08 = 0.23 grams per kw

Alright, these ladies are mid way through week 7 day 52 of bud. Just 3 days ago i started the flush stage for these plants even tho I’ve heard 1000x that it’s not necessary for organic gardens. I still do it just because. So these ladies got fed 2gal each of plain PH corrected water. With no sugars of any kind added. They all seem to be flushing out very well with most of their leafs turning yellow with purple on the tips. If you see any crumpled leafs it’s from last week when I noticed my soil PH had drifted to high. So I’ve been trying to correct it but these ladies are just about done so I’m not to worried. It looks like we got 1 week left on the Train Wreck and maybe 2 weeks on the OG and the Melato. The Train Wreck actually looks ready to chop down now but when I got up close with a jewel scope I saw that her trichome development is only at 50% cloudy and 47% clear with maybe around 3% amber. So I’m sure she will be ready by the day 58 mark but the OG and the Melato will probably go to around day 65. Anyways thanks for checking out the garden. be sure to check in on next weeks update when I harvest the Train Wreck🤙

She is flowering more and more each day and getting bigger than I expected haha. I have had to construct a makeshift "scaffold" around the tent so I can hang the light higher. The leaves are now slightly to big for the tent, so I hope she dosent get much bushier. Lots more pistels, and lots more growth, quite happy. # new tent coming 😁

🌸 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.

Queste Fast Flowering sono super vigorose e crescono senza paura e senza timore alcuno, sono sorpreso di vedere come in così poco tempo sono già pronte per andare in fioritura perché sennò 5 piante in questo box ( 80x80 ) avranno spazio appena sufficiente…Ah e ho aggiunto circa 18/19g di Top Dress di Dogma Organics attorno alle piante e ho mischiato i primi centimetri…domani diamo solo acqua! 💦
