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! 🌱💪😂

Buds are developing. A bit slower than I anticipated but they are developing. I guess it won't yield very much but that's because of the really bad outdoor conditions she started with. Still very excited to see her progression, I hope she keeps that dark green color. As you can see, the drip irrigation system arrived, which is good. Unfortunately that means that there will be no more Pet's&Pot pictures until harvest :( wish me luck!

Toujours trop chaud cette semaine. Les filles ont très soif, mais elle vont bien. Un peu de gym pour certaines et un traitement huile d,'holive ail et huile de neem pour toute. Ça commence à devenir vraiment cool, car je n ai jamais eu d aussi grosse plante et qu'il me reste encore un mois de croissance. C'est l'inconnu a partir de maintenant. Croisons les doigts

Tag 15 in der Blüte, an Tag 21 ein letztes Mal entlauben.

So she is growing fine I turn off my humidifier notice it was giving plant issues did raise the light another 12 in and I also topped her I almost forgot I transferred her to a 3 gallon bucket

Still just water and some fish shit Jan. 1 Happy New Year welp to start new year off drop my very cheap PH meter in the bucket water and now the readings are off and I probably watered them today with wrong pH water Sour diesel looks cool didn’t water today soil was still moist but the amnesia haze be

Start of week 8, Ladys getting Fade for nitrogen deprivation and a slightly higher PH of 6.3. Harvest next week.

started the flush this week. started to notice a couple of problems with drying out around 2 of the buds. raised the lights up to get some of the heat away from the top buds. a bit worried i left the flush too late.

Went back up to 25ml/10L ‚Autoflower-Supermix‘ as one of my ladies started showing first signs of a Nitrogen defifiency.

Bad Guy got hit with a heavy salt buildup, measuring around 1500ppm in the runoff. Planning to flush it during the next two feedings and see how it responds. Keeping fingers crossed for a swift recovery! 🌿🤞

High GD community, Week 29, All i harvested was much to early, and had some mold in there while drying, so yield is very low. These popcorns i let go an other week, so i get i tiny taste of the real taste. The tiny buds got much more fat these last 2 weeks, and aroma is getting intenser but not stinky. Little video of my 2 friends playing in the warm greenhouse. Both 9 years old and inseparable. Thats it for this week boys and girls, Thanks for reading and passing by and 💚💚💚👏👏👏👍👍👍 for Marshydro leds. Quality/price top!

Set 1&2 are out the green house in an outdoor setting but still under light....did some transplanting gonna do the rest in the upcoming week hopefully n maybe take some cuts other than that everything else running smooth Harvest the mother tree at the beginning of the week with would be about 6 weeks....took a few samples n she's hitting to say only dry a few days scent, flavor and effect are on point....still curing her out

The two KANNABIA plants almost harvested the same, the PINEAPPLE DREAM harvested 63 grams of dried bud and the ZKIT KANDY DREAM harvested 62,7 gram. That is a VERY GOOD RESULT and I am very happy with that. The plants grew very healthy throughout the whole cycle and developed lots of leaves (with very long stems!). At harvest time that meant loooooots of work for the scissors, but it was all worth it seen the outcome. The 2 plants harvested lots of buds glistening with trichomes and exuding a VERY SWEET SMELL.

Honey Melon Haze and O.G. Kush have been transfered into final pot (26l). Pots supports have been installed. The two Mandarin Punch (Auto) grow well but since their germination has been done a few days later, they are still too small to be transfered into their final pots. It should be for next week :) I put a pH meter in both 26l pots and the pH is 7.0. It's not perfect but it's ok for soil.

Really happy to harvest this girl. Made sure I pushed her to the max. Just about 70 days. She was done around 65. 14hrs into pre fower and beyond. I find that with High ppf with less hrs. Makes for much better phenos. Really happy to say. This is SUCH A 100% TOP strain. And it'll be 500% a auto that I'll repeat Mind you I've hardly ever repeated any strains. Except mimosa X orange punch auto and super lemon haze. And a few CBDs. So, if anything that should speak volumes to me saying this is a tip top strain. Going to run her with one of their new autos, apple strudel is meant to have very high terps. All about the taste. And this Apricot Auto from Fastbuds has this in spades.

Que hay familia, volvemos con malas noticias, un ejemplar salió hermafrodita y toco sacarla de su hueco os dejo fotografías de algunas ramas. Las 2 que quedan no pintan mal , se me fueron mucho de altura pero bueno XL. Ph controlado en 6,5 temperaturas máximas 28 y mínimas 19 , sin problemas aparentes. Variedad algo difícil para principiantes.

Used 300 watts, produced over 400 grams of dry, extremely dank cookies. Thanks to top quality genetics, lights and nutrients.

Think they ain't gonna stretch much now looks ok had to flush soil as she definitely dosent like alot of food light feeds for this strain maybe up It later on using very cheap led grow lights this setup is very cheap but it's for me to see the difference between a perfect setup to a budget setup still has most things she needs good airflow humidity is good can get hot as I didnt invest in ac but nothing over 28c most days they sit at 25c humidity 55% they growing quick even with no feed for 7 days this grow isn't at my home so only see these girls every 48 hours maybe 24 hours I'm feeling to check them day 35 and they stretched like crazy
