Until now it has been smooth sailling, my leds from @spiderfarmerofficial are at 80%, the temps are at 25 degrees Celsius and the humidity around 50/55! Amazing growth and healty colors are the words to describe this 3rd week of the Guava Auto (right plants) and Apple strudel Auto (left plants) from @fastbuds_official ! #mygrowdiaries are at 80%, the temps are at 25 degrees Celsius and the humidity around 50/55!

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.😍😍😍

This girl it is a very resilient client has only received mistreating him from me I have them all tied up like a bouquet of flowers came in then no space to breathe and no place to move because it has such an incredible stretch and growth that it was taking over the light of the entire tent despite being a back up plant that I put in the same planter with another string that I thought I was going to lose her this one is very strong and I have not allow her to develop properly so it is very Bushy plant I am not sure if it’s me or is the strain of plant nevertheless it has a very vigourous growth thank you for reading I will continue to update have a happy grow

My Sticky Rice plant is still quite small and hasn't shown a ton of growth yet. It's definitely the runt of the litter, but I'm hoping it'll pick up soon and fill in some of that extra space in the tent. Fingers crossed! Okay, This past week has been absolutely fantastic! The weather has been incredible, and I've been able to keep the windows open almost the entire time. My plants are thriving in the humidity, and the VPD has been perfect. Everything just feels so balanced and in check.

Intenamos no superar los 27 grados, y no superar el 50% de humedad, se ha bajado 25cm el foco progresivamente en 3 dias, sigue a 90w. Se he pulverizado preventivo de tierra de diatomeas.

Cold snap past few days and my furnace is struggling to keep up, day temps around 75 F night 65 Video is overexposed, shows size difference between a 5 gal fiber pot and 10 gal SIP. 2/3 of the fiber pots did not stretch well, can see the one that did stretch in the back hiding.

The Grow: This was an outdoor grow, although I started the Wedding Cheesecake FF (Fast-Flowering) indoors in early spring as the weather was still too cold to put her outside (nighttime temp's were dipping regularly into the 30's℉). The plan was simple... let her grow inside under a 19/5 light schedule until the nighttime temperatures stay above the mid 40's℉, at which point she was moved outside and transplanted into the soil which I had already setup with slow release dry amendments and inoculated with beneficial microbes, followed up with top dressings every 3-4 weeks with amendments and worm castings! She was a thirst and hungry girl and grew and enormous trunk as well as having a root system that was expansive! The Wedding Cheesecake FF grew for a total of 182 days from breaking ground to harvest, with 55 days of it in flower.

Really happy with the growth. Full of buds. Not much smell get close its a cat piss smell. Im hoping for more bud size development something close too @doctorphilgood
