1/12 4:14AM MONDAY!!!!!!!! CBG IS GOOD!1 LOWERD THE WATTAGE, EFFICIENCY IS GOOD. GREAT WHITE MYCO HAS INCREASED UPTAKE AND AND!!!! PHOTOSYNTHESIS EFFICIENCY ......FUCKING AWESOME 💪💪💪💪 1/12 4:47AM I asked GROK: are samsung leds on my mars hydro lights seem more efficient than the PPFD meter says, I lowered the lights again by a few watts? 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. 🥊🍌👨‍🔬🚨🌞 1/13/26 7:47AM BRUTAL WEEK FOR THE MOP AND BUCKET GUYS AT MUDRUROS COMPOUND 1/13, 11:22 AM banana purple punch auto RF three is doing really great. I haven’t really needed to do anything. I decided not to top. I didn’t want to do anything except light stress training. I think she’s gonna turn out just great. Her stock is one of the thickest. She’s just perfect.😍😍😍

End of week 8 and the beginning of week 9. 1-2 weeks left before I chop these girls down. All my girls are loving the new light and so am I! Highly recommend. Only things to report on is, I’m still flushing, my buds are getting denser, and also they’re starting to turn purple! This is my first plant to actually turn purple and I grew a plant just before these two that’s were supposed to be purple, but never did change colors. Fun fact: my favorite bud to smoke all time is purp diesel, so this is great for myself! Well, see you guys on the next update. Happy Growing! ✌️🏾

From website seed stocker they said this BCN need 75 days to harvest. So, at the end of week 11(77days) is very nearly to harvest day. Next trichrome check found almost 75-80% already cloudy. I thing if no any problem should be ready in next 1-2 week.

HEY GANG UPDATE!!!!!!!!!! SORRY FOR DELAY!!! SOOO LOOKS LIKE THEY GROW TENT IS GETTING WARMER THEN USUAL GIVIN THAT IT IS GETTING CLOSER TO THE HOTTER MONTHS OF THE SEASON, IM GOING TO INTRODUCE THE "EXHALE CO2 BAG" INTO THE TENT, HELP THE PLANTS OUT WATERING IS GOING WELL, NUTES ARE GOING WELL, HOPEFULLY WE CAN TURN THIS AROUND!!! OTHER THEN THAT JUST WAITING ON THE GIRLS TO START STACKING QUICKER! LETS GOOOOOO!!!!!!!!!!!!!!!!!! ANY ADVICE IS ALWAYS SUPER APPRECIATED THANKS GUYS!!!!!

She only grew 1cm this week. She's really charging through flowering. Trichome production has been high this week. I wish there was a way to view the pictures in hi-res on a desktop pc instead of the small window. Timelapse this week is almost useless. No input from me other than watering/nutrients.

So this week the bud rot took the life of two colas that I had to chop off But plants are looking healthy the one that I was concerned about look like it slowly healing had to add 1g of bio grow just to boost it nitrogen levels. Still might harvest a week early depending on what the thc crystals look like.

She's doing ok. Looking forward to this. I have topped her at the third node and remove the first so I will have 4 tops in a fashion. These will each be topped and node 2 removed so she should end up with 16 equal tops in size and location.... hopefully

Pulled the orange cookie today and couldn’t be happier, the yield is massive, the buds are dense, fruity sweet , sticky and pungent. This plant is prolly my best so far thanks to Dutchfem for another awesome strain . If you’re looking for something special give this strain a try . I’ve smoked a bit of this already and it’s Girl Scout cookies all over then just like a pallet cleanser of citrus freshness that keeps you coming back fir more .

Olá amigos, obrigado por seguir meu diário! Siga meu perfil, deixe seu like, comentário ou pergunta, ficarei feliz em ajudar se puder. Mais uma semana demonstrando uma deficiência que me parece ser Magnésio, mas é sempre complexo quando se trata de coco porque o equilíbrio entre K, Ca, Mg e Fe é ainda mais complexo neste tipo de meio. O fato é que esses clones foram retirados com urgência sem que eu pudesse selecionar a mãe antes, e a planta mãe apresentou essa deficiência o ciclo inteiro e não havia nada que eu pudesse fazer para corrigi-la, então devo estar condenado a isso novamente. Vivendo e Aprendendo! Fiz um ajuste na nutrição para poder testar. O objetivo é conseguir entregar o ppm de cada elemento bem próximo do feedchart Advanced Nutrients, mas usando fertilizante mineral muito mais barato e mais acessível no meu país, e algumas sobras que tenho da @casadasarvoresgrow
