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.😍😍😍 2/1 4:20 AM setting up a new tent for flowering using two Mars Hydro TS 1000 lights at 50 W each. I’m getting about 500 PPF that’s good enough. I’ll keep the lights close to the plants. The wattage is low so the heat will be negligible should be highly efficient grow

There’s a few things I’d personally change if I was to grow fat Banana again. But this time round she was very resistant to high temperatures and humidity during Flower. She holds on to nitrogen so I’d definitely feed her less on the nutrients as she is a light feeder.

las week was very good, the plants grow a lot and all the colas are blooming as much as the main, this week ill apply neem oil again to prevent plagues, and experiment with the SCroG that last week didnt do. BD3 (the one that lost cotyledons) is growing super fast, its 1 week late than the others and i didnt do to it LST, i want to contrast the results with and without the technique.

5/1 Plants are being rock stars. The event horizons and toasted toffy have been lollipopped abd it looks like lsted. I need to tie down the branches. The one sherb pie looks like it has a little bit of light burn but everything else is doing awesome. 5/2 Didn't write anything I forgot. 5/3 Plants are still doing great. The event horizon is coming out of reveg and isn't so twisty. It's time to start LSTing. I just haven't had time. I'm planning to put some work in today. Soil still seemed a little wet. I FIMed a GMO. I'll wait to see how that turns out before I do the rest. After today I'll have more time. Plants still aren't DIRECTLY under the light. I want to turn on both switches but I'm afraid they'll burn. 5/4 Still going strong. Watered today. Used approximately 3 Gatorade bottles. I tried to split one bottle between 3 plants. I want the roots searching for water. I want these 1 gallons to be full of roots before the transplant. I'm thinking I may do some lsting today as well as some topping or FIM. I'll update. Seedlings seem to come out of that stall. Didn't think they'd make it. 5/5 When I arrived I realized I had left the light OFF from the morning before when I was watering and inspecting things. Hooe this doesn't mess things up to bad. I've got one event horizon that's having trouble coming out of reveg. Everything else looks good. Those stunted auto seeds are coming up with their Second set of leaves. Definately took long enough. 5/6 I got close and inspected every plant. I really want to flip the bloom switch on too. I turned it on for a minute and it's bright as fuck. I think if I could find a way to raise the light higher (I'm working on a theory) I might be able to flip both switches. However I'm noticing what looks like light burn or light stress on some of them. It's not the too of the plant though. It's like the serated leaves are turning in on themselves. The 2 that I think reveged are turning their leaves inside out. Not sure if it's a reveg thing or has something to do with the light. I raised the light at noon. I'll see if this has a positive effect. The shades only partially block direct sunlight so I may need to make sure that's what's not causing this. The 4 gmo show no signs. I moved one almost directly under the light to see if it had an effect or if it's strain dependent. I'm definitely need to learn how to use l.e.d's better. Oh well. They'll go outside in less than a month. 5/7 I'm hoping leaving that light off didn't fuck with the clones that revegged. Raisingcthe light was a good idea. I can raise it higher and I'd like to hit the other switch. It's so much brighter and the gmos don't have any burns. They'll be going outside in a few weeks anyway. I was going to but a parmeter and I still might. The auto seeds are coming up pretty good. It's in the 60s today. I might bring the girls outside on the covered porch and see how they do.
