Day 79 since seed touched soil. Found some bud rot on other strains yesterday, so made early chop for #2 and #3. Both needed time, #2 needed like 3 more weeks, would be huge ;))) Day 112 since seed touched soil. last one is done. Ganja Farmer 2024 project is over. Happy Growing !!!

6/13 tried to do some LST about 3 or 4 days ago and today she was standing up straight. So I tried again and hopefully ahe wont be too strong and pull the ties off again. Shes exploding with growth. There are pistils already as well. Fed her for the for at time today with actual npk. Hope all goes well 6/16 she handled the feeding well. Tucked leaves and used some LST clips

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! 🌱💪😂

10/15 This week saw a few snags. Both gorilla zkittlez girls are showing what looks like a Mg def i.e yellowing between veins and green veins themselves. This isn't the first time they've exhibited these symptoms. Currently the heaviest affected leaves are the lowest fan leaves farthest from the light. Aiming to keep it that way. I think it's pH swinging too low. I need to pay more attention to my feeds but sometimes I don't have the time to pH my water as properly as I should. The reason I say it's that and not a deficiency is because they are also showing signs of over feed (yellow leaf tips) only a one half-strength feed did this. There must be plenty of food left in the pot. I'm thinking the flip is gonna come at the end of the week. I'll clean up some lower foliage tomorrow or Sunday and let them grow the rest of the week. 10 weeks seems like a nice round number to me. More pics coming when I do my defoll. 10/16 added some pics and vids

Buenas a tod@s... Otra semanita más para las niñas, se supone q es la anteúltima semana pero siempre queda algún día más seguro... Está semana se quitaron y agregaron nutrientes nuevos para esta etapa de la floración, de momento todo en orden, este rmario salió muchísimo mejor a comparación a otros diarios, eso desde mi punto de vista. Tanbm le quité varias hojas, haciéndole hueco para que entre más luz x debajo, ya había aquitado pero tenía bastantes otra vez. De momento todo en orden... La semana q viene ya vemos q tal van... Un saludo y buenos humos para tod@s... 💨💨💨🙌🏻👍🏻 😎💀🇦🇷🤝🏻🇪🇦

This week I continued trying to expose as much light as possible to the bud sites by getting rid of some fan leaves and tieing branches down as best as I could. I never quite know how much to take off the girls when they get hair cuts but I am confident there is much more light getting to the lower bud sites now. No nutes this week just ph water at 5.9 There are 3 plants that I am loving the most so far are a 6 shooter plant in a small pot, she is large a well spaced out nodes excited to see what the bud she produces is like. Never smoke any before. Very interested to try again in a 1 gallon pot. The zkittles og is another that has shocked me. She is in a larger 1 gallon fabric container an to be honest is exactly the right size and nicely bushy too. If the tent had 4 or 5 zkittles plants like that one i think It would be perfectly filled. Something else I have learned from growing multiple strains at once in a tiny space. I have smoked this before that I grew and loved it. The 3rd plant in buzzing with it the cosh kush from zamnesia. Again it's in one of the 1 gallon fabric pots its grown to a nice height for my tent with nice side branches. Grew this outside last year and got a little bit of smoke was alright I'm hoping with it been grown indoor will make it pretty dam tasty. I had a missile 33 seed going outside that's doing shit, think I gambled to early with my outside girls this year. Will take a pic of my 3 faves for you all next week if I remeber Peace 🍁

RQS . STRESS KILLER AUTO CONCLUSION BEFORE HARVEST. Harvest time is here, choose to do a final post with how the girl looks after the final flush, so enjoy. If you are looking for a super resistant strain and easy to grow functional medical strain this is the one. She was given tap water, and used flawless finish for 6 hours then flush again, 2-3 times in this two weeks, expecting top shelf from her.

I didn’t get a chance to update last week, so this is a 2 week gap, my bad. Anyways, I fed her Recharge @5 grams/gallon, and Grow Big @5 ml/ gallon. Continued to perform some LST.

Fun week! Taking this grow a lot more serious than the first run, applying all the goodness I'm learning along the way. Had to pick up a new pH meter. Found out the one I was using is/was off by about .3% which was throwing me wildly out of pH range across my grows. Honestly surprised I didn't fry all these poor little ladies. Super pumped we caught that. Now things are exactly where you'd expect them to be...happy and healthy. I'm also running this mini fully organic as well. I'm making some FPJ from kitchen scraps now, probably start that tomorrow or the next day. Funny that the container is so small I'm watering with a syringe. 😅 Hope everyone had, and is still having an awesome week! ✌️🌱

Yes, they are really getting big—so much that the grow tent is now completely full. It has been quite a challenge to keep the humidity under control since I don’t have a proper extractor yet (that will definitely be my next purchase). For now, leaving the tent open has allowed the air to circulate well, and the humidity stays around 45%, which is acceptable. Apart from that, everything has been calm and steady, continuing with the BioBizz feeding schedule and gradually increasing the nutrients to encourage the development of larger colas. The only drawback is that the colas are not turning out as thick as I had hoped. Interestingly, RHC #2 and #3, even though they are not the most robust plants, ended up being the tallest ones, and their colas actually look bigger than RHC #1. Overall, I’m happy and counting down the days with excitement.

Day 64 - I've been patiently waiting for the time to come, and it's finally here! Changed the lights over to 12/12 to send the tent into flower. Current light settings R99 W99 B50 as suggested by California Lightworks. I did a full reservoir change - switching over to bloom nutes. I also added some Si28 and P31 Microbes to the reservoir to test out this new product that I was fortunate enough to receive samples of. I've seen the results of others with crazy booming root growth.... Let's see what happens! Day 65 - I swear, it's like she's been waiting for me to flip the light cycle. I kicked one plant out of the tent so now there's even more room for improved air circulation and light distribution. This plant is a serious beast! Day 67/ Day 3 of Flower - Last massive round of defoliation before I sit back and let her do her thang. ✌️
