Crescendo muito bem as princesas, apenas com duas regas com nutrientes uma na primeira semana e meia de vida com o rootfast da Aramis, e a outra está semana com terra leaves 2.5 ml/l...já fiz algum desfolhamento nas partes baixas das maiores para desobstruir os novos rebentos em direção ah luz... Aguardando o tão desejado fruto... Abraços

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.😍😍😍

First things first, the smell coming from the lemon is absolutely delicious! Super super, almost like candy with a super sour hint to it. I am so keen to taste her! LSD-25; Fattening and fattening, she's starting to stack on the weight now, I'm hoping for another 3 weeks before chop. Lemon OG Haze; The buds are really starting to form now, I'm hoping to have some nice looking colas come next Friday. Imma giver her probably 5 weeks at this stage, but she is a bit of a slow grower so we'll see.

Upgrading to a r/o system in 2 weeks. Did the jugs this week,…last time. Basic reservoir change this week. Ph’d to 6 and ppm’s are around 750-800. Love the growth and shape of lemon haze auto. Just snapped the stem of gsc auto today trying to tie it down. Stem was thick as can be but so wet and new, snapped right in half. Fml. Just praying the way I propped it back together holds and maybe the side branching will take off and blah blah blah. Just sucks. Happy as can be with the progress. On a 4 week offset on 8 plants, 4 rotated at a time if I keep this up. What I’m hoping for at least. Self sufficient and supplying tent. Update Tuesday morning. The poor gsc auto that I broke in half grew back together literally overnight. Have seen that with branches but never the main stem and never that fast.

Into week 4 and they have blew up on me again. #2 still lagging behind but showing new growth at a decent pace. I think she will be the black sheep of this grow. So far I have performed another round of topping and very lite defoliation. (Can i get more aggressive anything under the main canopy? Watered them in with dechlorinated 6.8pH tap water. I think I may have to think about when to start top dressing them. Maybe 2 more weeks? Lol Also noted that I they are starting to suck up allot of water! May have to start wetting out the whole pot now and see how they respond. So far its a garentee to water them ever 3-4 days. Now getting much closer to 3. Hope you guys enjoy the video commentary and photos. I'm a bit lazy and maybe one day put a little more effort to taking better photos with my phone. Cheers

Nice dense buds. Pain to trim, but worth it. Seemed a bit nutrient sensitive. I am really impressed with the potent stativa-leaning buzz, will be growing this again, that’s for sure.

Plant is 8 weeks from seed today, stretching has now stopped and she is starting to fill out now. It looks like the feed will sit at 2ml A +B to a litre as she hasn't shown signs of wanting anything more although pk 13/14 will be added in roughly 3 weeks time. She's been drinking a lot more last few days

Left and right have both been topped for the second time on D31. Increased the EC and the plants seem to be growing very well! Have started to train the plant in the middle out, the other two I am not going to train until D33.

It’s day 43 of flower! All of the plants look great! I’m going to start dialing back the light intensity slowly over the next couple weeks. Harvest time is getting close

Unfortunately what we never want to happen has happened with my baby.. bud rot.. on day 98 of cycle I found 1 bud with bud rot, cut it off, checked the plant and could not find more.. flushed the plant and wait next day to see how it goes. After 2 days main bud was identified with bud rot too.. so sad.. probably due high humidity in my environment + colder weather we are starting to have.. so on day 101 harvest it.. could go few more days to get more amber trichomes but decided to harvest it to avoid lose more buds .. I will keep watching it to see if no spread when drying :(
