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! 🌱💪😂

Its week 11, Harvest time!! .... or is it? Well, i can tell you - absolutely not. 💩 #3 is well into flower right now, but i dont think she's gonna come down for another 3 weeks. She's def. the furthest along though. I'll be using the thrichoscope end of this week i reckon. #2 and #1 are both just barely getting started in their flower, so they will probably run for another 5 or 6 weeks at least. i've got good hopes for plants 2 and 3, and also feel like the light-intensity experiment is really giving me some solid results. (the one with the least light is #3, whhich even started to flower much sooner than the other two, i feel like there is a link with the scarcity of light energy it receives. anyone here that would confirm or deny such an idea?)

1/8/2024: so far the grow is not off to a great start. The browning that started on the cotyledon has spread to the other leaves and her growth has definitely slowed a bit. I used some water that sat out for a few days, so that may have been the issue, but I'm not sure why that would cause a problem. The ph was at 6.2. I also foiler fed them with some Tweetmint, which i think is the issue. I may hav3 not diluted it enough, causing the buring. I'm laying off anymore IPM until the olants bounce back. I also turned the lights down until i can get the plants back on track. It may just be the soil is too hot, but I have other plants in different soil that are showing the same symptoms, so it makes me think it's not the soil. I'm not giving up yet, but if things don't improve soon, I may just pop a new seed. This is my biggest issue with auto flowers. If the grow isn't perfect I could end up stunting the plant too much. I guess we will find out. 1/10/2024: Day 10 - the new growth is coming in healthy. I'm pretty sure the foiler spay I used last week is what caused the issue. I went back and realized I used way more of the concentrate than I should have, which likely burned the leaves. Let's hope that is the only mistake I make on this grow and it doesn't stunt the plant too much. 1/14/2024 - Day 14: she is looking so much better. All the new growth is as healthy as can be. I added a new light today. Replaced the Spider Farmer SF2000 with the AC Infinity Ionboard S44. I originally had the S44 in my 4x4, but recently bought a light with more Watts and better coverage for the 4x4. The S44 is probably overkill for the 2x4, but it fit, so I figured I'd give it a try. Only have it on at 60% at the moment and I'm getting about 500 ppfd, with a DLI of 30. Dropped the light cycle down to 18 on and 6 off as well. I have some photo period plants in the 2x4 as well, and I wanted to shift them to 18/6, so the auto is going along for the ride.

07/08/2020 Powdery mildew has cleared up got bird poop on leaves now will clean, and defoliate as needed🙏 Red Sky clones do not take light stress well be on top of that shit with a timer! The first clone I took I put under 24 hour light (on purpose)sent out male flower at several nodes (collecting for Feminized project) So no light stress, unless you need to!

9/8/2024 day 1 of veg. looking happy and healthy. im dealing with fungus gnats from other plants in the tent. i think the peat pellet wrapping is keeping them from damaging the young roots at the moment. im using diatomaceous earth in an attempt to keep them at bay. 9/11 day 4 theyre starting to show small differences. excited to see where these 9/12 so far im noticing one plant that stands out from the rest. she has longer petioles than the rest and seems taller and lankier. its still early on though so hard to say anything yet for

WEEK 2 DAY 14 Since last week the babies have taken off! They didn’t have much light until yesterday when I added another 100w led and since then I’ve seen a huge difference ! They are looking super healthy the roots said fuck the pot and grew right through it I’m actually super interested in seeing how these grow up.. The 3 clones that were separate last week are now moved into one single pot to further develop the experiment. They are on the same feed as the mother with flora grow/micro/bloom and cal-mag . And In the last picture you can see my ghettos man way of cloning .. going to see which 2 out of 4 are better rooted and I will move those to a pot in about a week or so. If you guys have any questions or want to know where I got these exotic seeds message me!! Or comment below !
