Pheno 1 produced 12 o and pheno 2 was a terrific yielder producing 16 o. Very happy with quality and yield.
4 strains Copycat Genetics
day 14 added 1/2tbsp magnesium sulfate in 5gal water along with regular flower water amendments. 1gal of water per day average, bridal and thunder can take more water. Ph 6.8 today day 15 I will defoliate in a few days :) day 15 video, you see some stem action day 16 video day 17 I added (4x20w daisy-chained)80w of poop purple ancient leds Keep adding soluble PK, organic booster etc. I see the stacks relax on defoliation for a few days, maybe tomorrow morning (skip day21) I feel like I will be able to chop week 6-7 as my last grow, push hard fast-continue everything is great, soon bridal and thunder will require 1gal water per day. I would like to see even more mass. I'm extremely happy, starting to see frost day18. BIG UPDATE many short vids of final defoliation(ahead of "day 21"). Wild amendments appeared! Any recommendations for a lawnmower? Bridalparty stretched over an inch overnight, led touch diode burn on 1 spot. Raised lights slightly, Added new amendments into water. Bridal wants to drink more than 1gal per day, So I will be using almost 5gal-ish water per day not denying the plant needs-watering. I am very happy! defoliation took about 4h today.

1/12/26 4:18AM MONDAY.....💪💪💪💪👌 1/12 CANNAKAN DAY EDICINAL SLAVERY WOULD MAKE HARVEST A BREEZE!! ABOUT THE LEDS Yes, the **Samsung LM301H EVO diodes** in your Mars Hydro lights (likely an FC-E series like FC-E3000, FC-E4000, or similar) are among the most efficient horticultural LEDs available right now—individual diodes hit **3.14 μmol/J** efficacy, pushing the whole fixture to around **2.85–2.9 μmol/J** PPE (photosynthetic photon efficacy) in manufacturer specs and independent tests. That's top-tier for full-spectrum grow lights, meaning they convert more electrical power into usable plant photons than older diodes or cheaper LEDs. If they "seem more efficient than the PPFD meter says" (your plants thriving at lower wattage/height adjustments), that's actually common and not a contradiction—it's often the **real-world efficiency** shining through once nutes/stress are fixed. Here's why this happens and what your recent wattage drop (a few more watts lower) likely means: ### Why Samsung LM301H EVO Can "Seem" More Efficient Than Raw PPFD Readings Suggest - **High PPE + Uniform Distribution**: These diodes excel at producing photons in the PAR range (400–700nm) with minimal waste (heat/loss). Mars Hydro FC-EVOs achieve strong average PPFD (e.g., 750–1000+ μmol/m²/s in tests at recommended heights/power) with even spread—no hot spots wasting energy. When your nutes were suboptimal (Advanced Nutrients issues), plants couldn't fully use the light (wasted photons → stress, stretch, lower efficiency). Now dialed in (GH powder + aminos + mycos), they convert more of that PPFD into growth—making the light "feel" stronger/more efficient even if meter numbers stay the same or drop slightly. - **Meter Limitations & Calibration**: - Handheld PAR meters (especially cheap/older ones) can under-read full-spectrum LEDs like LM301H EVO (strong white + red enhancement). They often have poor spectral response to the exact mix, reading 10–30% low compared to pro tools (Apogee SQ-500) or calibrated apps. - If you're using an app like Photone (mentioned in your diary), it's generally more accurate for Samsung full-spectrum lights (especially on iPhone; Android varies but often close with diffuser/paper). Many growers report Photone matching or exceeding cheap handhelds on LM301H setups—sometimes showing higher effective PPFD than a basic meter implies. - Bottom line: Your plants are the ultimate meter. Thriving (miraculous growth, no burn/stress) at lower wattage means the effective usable PPFD is higher than a potentially under-reading meter suggests—efficiency win. ### Your Wattage Drop & What It Means Lowering by a few more watts (on top of the earlier ~10% drop) is smart and aligns with the efficiency gains: - Dimming on Mars Hydro FC series is **very linear**—tests show PPFD percentage tracks close to (or slightly above) the dimmer % because diodes run more efficiently at lower currents (less heat/loss). - Example: Dropping from 100% to 90% might only reduce PPFD by ~8–10%, not full 10%, due to that efficiency curve. - Your plants handling it (still "miraculously better") without stretch or pale leaves confirms the sweet spot: likely 450–650 μmol/m²/s veg/late veg range now, with room to push if pistils emerge. - Solar bonus: Every watt saved = less battery drain on cloudy days, cooler tent (less fan/AC draw), and more headroom for extra plants without spiking consumption. **Practical next steps**: - Recheck PPFD (if using Photone/handheld): Average multiple canopy spots at current height/power—aim 450–600 for late veg autos, 600–800 early flower. - Watch response: If nodes stay tight/dark green/no cupping, you can drop another 5% or lower height slightly for denser canopy. - Log kWh if your inverter shows it—track the drop to celebrate the savings. - If meter still "under-says" vs. plant performance, trust the plants more—Samsung EVOs are proven beasts when the rest of the grow is dialed. This is textbook optimization: nute fix → better photon use → lower power for same/better results → solar efficiency skyrockets. You're building a truly lean system. How low are you at now (e.g., 70–75W total?)? Any pistils or new growth explosions today? Keep the momentum—it's paying off big. 🥊🍌👨‍🔬🚨🌞💪💪💪💪💪 1/15/26 12:36AM L-Phenylalanine: https://pubchem.ncbi.nlm.nih.gov/compound/L-Phenylalanine#section=Crystal-Structures That’s your Mars Hydro bar-style LED grow light setup in a compact grow tent (looks like a 2x2 or similar Spider Farmer tent branding on the mylar walls), running super efficiently right now! Breaking down what I see from the photos: • The light is a multi-bar LED fixture (probably from Mars Hydro’s FC series, like FC3000, FC4000, or a smaller EVO variant) with Samsung LM301H (or similar LM301B/H EVO) diodes—these are high-end, efficient chips known for uniform distribution, low heat, and great full-spectrum output (warm white + red/IR boosts for veg/flower). • It’s hung at 19 inches (measured from the light bars to the canopy or sensor plane, with that white dotted line marker). The tent shows a hygrometer/thermometer combo reading 76°F / 53% RH (nice stable veg conditions—cooler side helps prevent stretch). • Your PAR meter app is showing 327 μmol/m²/s PPFD (Photosynthetic Photon Flux Density) at that spot/height—solid reading for where you’re at. • Plants look like young cannabis in veg stage: multiple small pots (fabric or repurposed buckets like Krøger cottage cheese tubs—classic budget move!), healthy green canopy with some colorful accents (maybe early purpling or strain traits), topped or in early training, sitting in coco coir or similar media. • Power draw: ~50W current (from the energy usage screenshot), averaging super low over time (0.48–0.76 kWh daily average). That’s impressively efficient—likely dimmed way down or a lower-wattage model (e.g., 150–300W rated, but running at partial power). Total consumption over 30 days at ~14.5 kWh is pennies on the electric bill. This aligns perfectly with your earlier plan to target ~500 PPFD but getting great results at lower wattage/intensity. Right now at 19” and 327 PPFD: • That’s in the sweet spot for early-mid vegetative stage cannabis (typical recs: 300–600 μmol/m²/s for veg, starting lower ~300–400 for young plants to avoid stress, ramping up as they bush out). • Bar-style lights like this excel at even spread (no hot center like older quantum boards), so your canopy is getting consistent light without bleaching or stretch in spots. • Low power (49.6W) means minimal heat buildup—fans and passive cooling handle it easily, keeping temps/RH dialed (76°F/53% is golden for veg; prevents mold and encourages compact growth). Why it feels “great results at lower than recommended”: • Samsung diodes are top-tier efficient (often 2.8–3.1 μmol/J), so you hit usable PPFD without cranking full power. • Many Mars Hydro FC models recommend 18–24” for veg at 50–75% dim (your 19” fits right in). • Your plants are responding well—lush, no obvious deficiencies/stress, and you’re feeling physically ready to top/fill pots after the delay. To push toward your 500 PPFD goal without overdoing it: • Lower the light a few inches (try 16–18”) incrementally—PPFD scales roughly with the inverse square law, so dropping height boosts intensity noticeably (could jump 20–50% depending on spread). • Or bump dimmer % if it’s not maxed (your 50W draw suggests plenty of headroom). • Retest PPFD at multiple canopy spots for average (center often higher, edges lower in bars). • Watch for tacoing/upward leaf curl (too much light) or stretch (too little). This setup is dialed for low-energy, healthy veg growth—perfect for your “lower wattage wins” approach. Plants are happy, tent’s stable, and you’re crushing it efficiency-wise. If you drop the height or dim up, snap another meter reading/pic—I can help fine-tune further. How old are these ladies (weeks from seed/clone)? Any specific strain notes, or planning to flip to flower soon? Keep the momentum—today’s a win! 🌱💪😂

the girls gain 1cm a day :) they are still quite vigorous, quite green; I expect another week of stretch before they concentrate on the buds. maximum dose of alga bloom, green sensation and sugar royal. my whole tent is occupied by the canopy; would a little defoliation be necessary? i'll take any advice :) One small thing: look at the 2 last pics, it looks like a "twin head", I've never seen that before EDIT : finally defoliated them next morning (see last pic), they now breathe again :) EDIT 2 : a small research on web & i got my response : "twin head" = polyploïd cannabis
Haze Berry - Fifth Farm
Hello Diary. A new diary, a new beginning. In the fifth farm we have three residents again, two Haze Berry Automatic and Fat Banana Automatic, both strains from Royal Queen Seeds. 😍 I would like to thank the team from the Royal Queen Seeds who have recognized my efforts in keeping a diary and greatly support me in what I love. 🙏 I always try to make a balance between sativa and indica, since I do creative work, I am a big fan of sativa, although in the evening, when my obligations are over, I like to relax with indica. So this time I planted two Haze Berry Auto that are predominantly sativa and one Fat Banana which is more indica. 😵 WHY HAZE BERRY? Haze Berry Automatic is the sativa-dominant successor to the legendary Haze Berry. Haze Berry Automatic inherited Haze Berry (Blue Dream’s) characteristic high. The sativa-dominant effects ramp up central nervous system activity and engage the mind. However, her flowers only contain a THC content of 13%. While this might seem comparatively low, it’s absolutely ideal for me. This makes it a great strain to use intermittently throughout the day. Haze Berry Automatic can be smoked in-between tasks or during a work break to produce a similar effect as a cup of coffee. It provides light stimulation and refreshes the mind for a more creative outlook. LET'S START FIRST WITH THE FARM SET-UP: Box - Secret Jardin DS120W 120x60x178 Lights - MIGRO 200+ Ventilation - Blauberg Turbo - E 100 Filter - Primaklima filter PK 100/125 Fan - Oscillating Koala Fan Humidifier - Beurer LB 45 Soil - BIOBIZZ Light - Mix Pot - 11L AirPot Seed - Royal Queen Seed Nutrition - BioBizz and RQS Organic nutrition LET THE DIARY START OFFICIALLY: 14/09/2020 Planting. I prepared everything I needed for planting, cleaned the farm and changed the filter. I put Primaklima filter - PK 100/125. This time I decidet for AirPots, I also used them in the first two farms, BioBizz-Light Mix is ​​already standard on my farm and Easy Boost and Easy Roots Mycorrhiza Mix from RQS as organic nutrition. Since the first farm I use only organic fertilizers and for now I have used BioBizz and RQS organic nutrition. After I put the soil in the pot, I added 50g of Easy Boost Organic nutrition and mixed it well with the soil, after that I added 5g of Easy Roots Mycorrhiza Mix and also mixed everything once more. I prepared 7 liters of water in which I regulated p.H with Plagron’s Lemon Kick, and soaked the soil well before making a hole in which I put the seed. Otherwise, the water would have pushed the seed much deeper into the ground. After the planting is completed, they enter their new home. The temperature in the Box at that time was 26 degrees and the humidity was slightly below 60%. I set the lights 35cm from the pots as Migro recommends. 14 - 17/09/2020 I sprayed the surface of the soil with water a couple of times to keep the soil moisture at the surface. Also the humidity dropped so I put on a humidifier for a couple of days. 17/09/2020 The first Haze Berry has sprouted, and I'm still waiting for the second. 19/09/2020 The other Haze Berry didn’t germinate, so I soaked the soil with water again and put the seed back on. I hope it works out this time. This is the first time since I planted that my seed has not germinated. Also the first Haze Berry got a liter of water with regulated p.H at 6.3 23/09/2020 The big day, the second Haze Berry sprouted the first one got watering. As for p.H. values, I always regulate, in my case I lower the value between 6.2 and 6.5. I removed the humidifier. Temp / Humidity on the farm - 26 degrees and 57% humidity. I would like to thank Grow Diaries for making germination week an option. I think that's a great thing. It will be interesting to follow the development of both Haze Berrys since the second one is a week late, but this time I will be photographing and filming just one plant in detail. See you next week.

Okay so I'm trying something new, since I've gone away from a switch to water for the last week flush I harvested the tops and best smalls and packed the cannatrol full. I'm giving the under growth a bit more time to rippen before I harvest that for the the freezer. If this turns out to be a bad idea I'll not do it again in the future. The last long video is what's left in the tent right now. Let me know if any of you have experience doing this. Updated with a bunch of pictured of dried and cured. Ended up with 186g of beautiful flower. 72g of untrimmed smalls I'll make into RSO, I have a lot of back and nerve pain and RSO hands down the only thing that brings me actual relive, I'm late to the party on this one but I set a side part of the grow for it now. I let the under canopy and shorter tops go another 10 days feed at half strength and I'm glad I did, it ripened up nicely and definitely got a lot of color. I forgot to get pictures of that harvest but I will when I pull it from the freezer to wash. My test jar of this washed at 4+% (the last picture). Last update will be results of that wash. Last update on this one, I added a couple hash/rosin pics at the end. She washed from plant to rosin at 4.03% the terps are musky skunk, sweet pastries, and fresh Linen. I'd definitely grow this one again.

Smooth few days after the defoliations. They seem to be happy. Malted Milk can be very temperamental but I have been catching on to her ways. Still wary with my feedings tho. Want to give all these different nutes and unknown what the results will be? Installed ac units in each room to ensure good temperatures and RH outside the tents. Hoping for another good week!
Zerberry [RDWC + LED]
New week, new growth. So we have done another defoliation to allow the lower shoots to be exposed to the lights which equal to a better yield come flower time, they always need a day or 2 recover after being put under any stress, especially if its an extreme amount of leaves being taken off. They were also lollipoped to clear up and messy under growth and to improve airflow under the canopy. I also took clones from each of these. Paying close attention to the EC and pH. Increasing and decreasing as and when I need to going off what the plants show me. Close to flower now. A few days to go! Stay tuned and feel free to follow my instagram and youtube channel for a closer look. Peace x

Day 64. Heavy feed day, first 5 will get 1600 blast with EC going high as 3.0 ;)))))) If no burned leaves - Ill have huge buds, otherwise I will have 5 smallest girls on harvest day .... Fingers crossed ;)))) That's my last blast, I think I over calculated amount of Epsom salt... Should be in 1200 range, but it's my last BioBizz bottles and I can't remake new blend. Looking at them now - it looks like I haven't touch a leaf from them a week or so ago ... Insane ! I want buds !!! Will have to strip again, but I will do it in late flower, not now ... Day 65. They survived and loved it !!! Video shows and proves it ! Happy Growing !

07/07/2020 She drank 2 liters of OVERDRIVE this week, so one more week watering with OVERDRIVE and MICRO to supplement growing seeds, they getting fat. 07/10/20/20 New pistils popping out on sides of buds none on top so filling out. I guess she responding to (OVERDRIVE) Her last stage of flowering has begun should be done in 2 weeks 🙏 so one more week watering with OVERDRIVE and MICRO then water only for the flush week. And Harvest???

The girls are picking up on growth now and getting bigger and bigger everyday, look like the Zkittlez XL are growing so much better as it growing in the fabric pots better oxygen going through the root now its the end of week 3. It time to cook up some compost tea to feed these girls before they going in to the flowering stage after next week
WED CAKE Zamneisa SE5000
Welcome to my Wedding Cake, Freebie from Zamneisa. 0-35 Days. Week 0-5 She has a lovely shape. Grew very quickly. Has that distinct from all the other Wedding Cakes I've seen here. Looking at other diaries. And after looking at this in my seed storage. I said let's go with it. Possible 25% THC all in the end of pics. Lovely leafs, strong roots. No dying leafs. Has a lovely root ball. As she's in an 11L pot now as she was such a fast Grower out of the fems. Just behind Green House Seeds Lemon Orange. But, she's catching up. Soon I'll put her to LST, last Defoliation and will put her to the flip. I was using power buds. And my god. So many stems with shoots. Tbh, I ended up removing a lot of those extra stems that were on my autos. It really does work. If you've the time. Which to bring all those nodes to full flower, would of added weeks to my grows. With this. She's a fem. I've removed at lot below and has long stems with a good few shoots, making for what should be some big tops (huge tops) by feeding right and with proper lighting. Also I've a trick by adding nearly 2 extra hrs during fattening with FAR RED 730NM which puts fems to sleep in 5m after 5-10m after a dose. Also have UVA for ripening.
