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 days of darkness during the flush begins. Had great results with Wanda and her genetics. Blessed for a first grow. Cut Wanda down at the end of the week. She’s now drying. I will be giving a thorough review for my harvest diary. Excited to share what I’ve experienced and learned from this grow.

wow wow !!!! 404 gr ! from the suitcase!!!!!!!258 gr of wet dried buds!!!!!!! I am impressed with the result, and I don't really believe that I will ever be able to improve it :) It was a truly amazing journey with FastBuds Gorilla cookies auto, my house is filled with a wonderful sweet smell, the buds look really full and very very shiny :) I also collected a lot of sugar leaves from which I will make bubble hash:) the girl coped with high temperatures and high humidity throughout her growth, which is why I was afraid of rot, but everything went well!!!! She is amazing. smoke review and dry weight will be up very soon, good luck to everyone :)!!!

Underground Seeds Collective is a cannabis seed bank founded by Landrace marijuana genetics lovers, to share the best strains of its collection on regular seeds form. USC is composed of different breeders, bringing each one its own philosophy of cannabis: pure Indica Afghani and Pakistani lines, elite clones such as Exodus Cheese and ECSD, landrace Sativa strains from Asia, South America and Africa, lost genetics as Ducks Foot... Furthermore the creation of new varieties as Durgan Chitral or Cheestral, Underground Seeds also contributes since many years to select and reproduce marijuana lines such as Jamaican Lambsbread, to preserve these rare genetics and make it available for the whole cannabis community. As usual I will follow The Grow Boss growing recommendations and I will use Cellmax Nutrients. For more details, growing tips and technics, follow Barney’s Jumanji [Week 10 Flowering] The main colas is about 1ft tall , this genetic is impressive , it have only 5 week of Veg ... (P.S: I’m looking for a job in the Cannabis industry as Master Grower, Mineralogist, Quality Control 🐞)

2/2: not much to report. Slow going, but going 2/5 NL: Still have a few weeks to go, but buds are fattening up. Watered with pH balance water as she was given nutrients on last watering. I didn't have high hopes for this plant. Still unsure of the density of the buds.

We chopped down the plants. Now they hang out to dry in the tent. The Trichs looked very good. Some milky, some amber, hardly any clear. Just the way I want it. The popcorn buds were rather milky. So we have more of a couchlock effect on the head buds and the maximum THC on the popcorns. I'm really looking forward to the taste💚

Due to the high number of tops that naturally produced themselves on the pop,,I had to start some LST,,and in the process,,accidentally knocked the top off it,,😁😂😂🙏 Thankfully the main stem plugged itself,,and the branches that have been trained,,,look promising,,,,🙏🙏💚🇦🇺

10.08 New Week, new nutrients. Adjusted the water level to 8L.

Coming soon

She has a sweet cookies and pine smell. Very frosty and should be a very calming smoke. I didn't have any major issues during the grow. Thank you Zamnesia seeds, and Medic Grow. 🤜🏻🤛🏻🌱❄️ Thank you grow diaries community for the 👇likes👇, follows, comments, and subscriptions on my YouTube channel👇. ❄️🌱🍻 Happy Growing 🌱🌱🌱 https://youtube.com/channel/UCAhN7yRzWLpcaRHhMIQ7X4g

Added nutrients to top off reservoirs everything looks good …I am content so far with testing will be dropping light schedule to 11 on 13 off to accelerate bud development hopefully shortening flowering time

Hey hoo let's go.

The 7 blue gelato 41s are doing ok theyre hermie/pollinated perhaps as the calyxes have swelled but gonna run them the whole way through as an experience for my first grow. The stems also smell very good like blueberry/ cookie

Sour diesel is such a beautiful plant, with a robust structure and strong lime flavor.. full of terps.. the main bud looks a big rock.. might be the biggest main bud I ever had.. super frosty and definitely a genetic I will want to grow again.. can’t wait to harvest this baby.. I’m gonna flush it very soon, probably next watering.. plant is definitely going to the last weeks/days.. let’s go

Corrected a few minor issues and she seems to be getting on well now. Hopefully i should see some steady and quick growth few minor problems at the start with light leaks causing algae but quickly rectified. Roots are looking healthy and are reaching through to the water. Back with an update soon. Day 26 - well on her way now, growth occuring everyday, currently at 1.32 EC and around 6.1 pH. Roots have exploded since two days ago. If i kerp this going garvest time will be the best ive ever had and ive had some good harvests in soil/coco. But yeah, very please so far. Updaye soon Day 27 - Dropped the EC slightly down to 1.28 as she was looking a bit toxic, pH seems more stable now but might lower the EC again slightly. Ill see how it goes for now.
