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.😍😍😍

Love this plant! So it’s a generic Slurricane cross abs she is getting frosty and tall! The two topped branches were stunted and the 2 outside are huge! Just giving her my normal feed schedule now with a weekly tea. Love this! ✌️🏻💚🌿💨

Things are weird this week. Mostly the weaterh outside is very unpredictable. Morning clouds with sun here and there. THings are more humid in the tent than id like. Anyways, girls stretched super well this week EXCEPT BBC L which looks like is suffering from some nitrogen toxicity. I need to dry out the soil and flush it with plain h2o tomorrow

Just hit day 10 of flower the left net has about 20% touching the 2nd trellis. And about 70% almost touching. The right net in the tent has 40% touching and the rest is close to the 2nd trellis. Gorilla Zkittles is growing strong. They occupy the middle back 4 pots of the net.

👉Alrighty Then👈 👉Cherry Punch F1👈 week 7 of flower Everything is looking good 👍Having issues due to using my well water , it's hard so I'm having slight issues but I am on it ..... So i continue to modify the nutrients to accommodate flower ..... Soil by Promix Nutrients by Cronks Lights by MarsHydro.ca FC4800 X UR45 X Adlite Deep Red And Blue Tent 4x4x6.5 & Equipment by MarsHydro.ca High reflectivity inner mylar Thick Oxford fabric Smooth heavy duty zipper Sturdy metal frame Zipper blackout cloth Good anti light leakage performance The 6in Inline kicks ass moves alot of air ●Blue Light Effect: Blue light shortens internodes, resulting in shorter, stronger plants, ideal for supporting fruit development later. During vegetative growth, blue light promotes lateral branch development effectively. Well this should be fun 🙃 Thanks to all my growmies out there for stopping by its much appreciated 👈 👉Happy Growing👈

Dec 12: Growth has been good, leafs started yellowing as I tried a regular watering as opposed to a feed, and they did not take well to it. I’ve read that it’s good to incorporate waterings between feeds, but 24hr later noticed a bit of yellowing on the lower section, 48hr post watering even more yellowing. Dec 18: Going with feed only and yellowing has halted, stretching has officially begun. No adverse effects from the short term nitrogen deficiency (that’s what I narrowed it down to). Playing with budsites to maintain an even canopy, and as soon as I see stretching halt, and fattening begin, I will up the bloom nutes. Dec 20:

Still struggling with humidity. But I have really good airflow and ventilation. Continue to defoliate plants. Stretch is over or at least almost. Due to previous lights one plant is about 3 days behind the other 2. Already smells great/loud. Girlfriend hates it. Not a smoker.

Nov 13: Hash washing using fresh frozen plant material. This Gorilla Cookies had nice yield with most of the trichome recovery being on the first two washes. Later washes were still very high quality. Bag sizes used are 160/120/45/45 which means the 120 fraction is still very decent for immediate use and what is caught on the first 45 micron screen has a nice range (full spectrum). That’s how Frenchy Cannoli said he did it, so fine by me. Washed for 3 minutes, then 3, 4, 6, 9 and 12 minutes. A+ grade on first three washes and then only slightly worse on later pulls. I tried fresh frozen before and it was a disaster with way too much green in the extract. This time I avoided trimming sugar leaves by leaving them intact or removing them whole and that seemed to work. Will confirm hash yield after freeze drying but seems good. Extracted resin is the perfect sandy colour and is now in freezer. The freeze dryer should be wired in and ready to go later this week.

Cette semaine, j'attends impatiemment l'explosion de fleurs et doucement elles explosent 🌱🌺 Les feuilles jaunissent je les enlève avant qu'elle ne tombent. 🍃 La température 🌡️est bien tombée depuis cette été. Cela devrait faire une meilleure récolte !

Week 9 of Flower & Happy Day 60 of Flower, you beauty 😍 She continues to stun with her amazing colours fading. I tried to best show her beauty with different bgr colors, with whatever is possible in my home. I decided against flushing her. I will decrease her feeding towards the end, but not flush her. Let's see how that works out. Currently guessing another 7 days? Let me know what you think :) Will post some trichome shots later. Happy day 🍃☀️ Day 61 - Took some trichome shots today. From the pictures I would almost say she's there? I see so many amber ones and purple transparent milky mixed ones. Hard to say. She's also almost red now, her leaves, no leaf left without fading... I didn't plan for her to be ready this week, aaaaaaaaah. Will she make another 5 days? I hope so. Also the light green shining things, what is it? I find them curled up on buds, they grow a white hair outside but they are curled like a little ball, is it balls???? I watered them today with 3l and a lighter feeding, 2ml bloom and topmax. I guess it was her last watering 😌 Looking at the trichomes and planning a little time-wise, I think I might let her under the light the whole tomorrow, then start the next in Darkness and leave her in the dark for the following 48hours. That should give me some time to prepare her harvest and upcoming drying situation a bit better. Exciting yeay 😝 Day 62 of Flower and 132 days in total and this lady has her last day with light. I went and checked her trichomes again, from top to bottom. She's ready 😍Now into darkness for min. 48 hours yeay
