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.😍😍😍

More to come!... don't even ask how I keep this tent in the 70s in the garage when it is already getting to 96 degrees outside..... short answer... "oh, this works, well it did work, maybe if I do this, that seems to help, well shit, that didn't work, uh oh, its getting hot, I got it!... and done. - temps start to climb into the 90s - " oh shit, oh shit!, Its not working anymore, I guess 90 degrees inside the tent is better than being in the 100s.... think, think, think, 😲 I got it!... annnd done👌! Its working. The temp at the time of writing this is... 73 degrees (last night it is was in the upper 80s lower 90s). So yeah, my wife is upset at the time I've been spending on it..... if only she would have let me do this inside the house like I wanted to. Meh, whatareya gonna do? 😕 There is something living in my attic... I hear it now.😒....

Ciao ragazzi e bentornati qui con me e le sorelle Limonose 🍋 Tutte 3 hanno smesso di crescere, la numero uno ha una struttura incredibile,💪 mi sono pentito di non aver fatto Lst su tutte le sorelle.🤦‍♂️ La numero 2 è alta e ben strutturata ma ha una sola cola bella grassa. Mentre la numero 3 sembra più avanti delle altre con quasi tutti i peli arancioni e i buds di media grandezza. Le cole principali delle altre invece misurano circa 3/4 cm, ma sono ancora parecchio indietro👍 Il colore è standard! Niente di particolare bei buds verde chiaro e pistilli bianchi ma sembrano molto gelide🤙 L odore delle sorelle sembra diverso tra di loro. La numero 1 ha note accentuate di diesel e nocciola, la numero 2 ha un profumo aspro tipo mapo e la numero 3 ricorda un dolce cremoso al limone 😋 Eh niente ragazzi! Aspettiamo che loro ingrassino per bene!👊 Grazie a tutti per aver guardato e restate sintonizzati per nuovi aggiornamenti.🙏 Buona settimana e felice crescita 🌱 🌱 🌱

Day 29. All goes well and easy, now i know size of pot, its around 720 ml . Girl is stretching, but not so bad, was thinking to take off few bottom branches - but i will leave her untrained i think. In few days i will water her, but generally she drinks almost nothing, compared to girls grown in tents with good air, light and humidity .... Stem went still nice even without any fan, she is stiff ... Found my first Liberties, wonderful mushroom trip ;)))) Day 30. She is healthy green and i think if i will need to add anything - it will be potassium in middle of flower, maybe even nothing ... Girl started to drink faster. Think tomorrow is watering day again .... Day 31. 70 ml of 6.3 ph water in. Before it sprinkled 1g. of BioSys. Day 34. 150ml in !!! Had some run off and collected it. Think it will be enough for 3-4 days, girl is drinking a lot recently ;) Happy Growing !!!!

The Red Hot Cookies are looking beautiful. Very nice looking buds with fantastic colors. Very promising in terms of bag appeal :) The pheno 1 shares many traits with the GSC. The effect is amazing despite of the quite boring terpene profile which is unidimensional (very sweet base notes along with creamy peach head notes that reminds me of the peach flavored campino hard candys). The high has the soothing and calming effect of the GSC while being more uplifting and energizing. The pheno 2 is more on the Tangie side for both the effects and the terp profile. The high is energetic but a little bit racy. The limonene content seems far higher than the myrcene, and it translates itself in both the taste and the effect. I will be looking for a Tangie-dom pheno that is richer in myrcene, in hope of getting more of the tangerine taste/aroma and the relaxing effect that we can find in the Tangie and Tangerine Dream strains. As for the Amherst Sour D, they all share the same woody and tropical aromas with subtle specific nuances (pepper, fuel, skunk/sulfur, lavender). The effects go from slightly sedating to highly energizing and euphoric. A great afterwork hard hitting sativa that tastes awesome, without being the terp bomb of the year. The Dinamed CBD plus is a very short, bushy and stalky plant. The Pheno 1 smells like straight pine/fir on sweet and fruity base notes. The structure is nice with lots of lateral branching and the buds are looking very good too. I could have got a way better yield be giving her an extra 10 days of veg. The pheno 2 is more one the fruity/fuely/tart side. Definitely not the best pheno. Very slow growth...

Vamos familia que ya actualizamos la cosecha de estas Frosted Guava de Zamnesia. Vaya flores que se han marcado repletas de tricomas, parecen escarcha y las flores se marcan aromas muy tropicales, la verdad que únicos. Es una variedad bastante fácil de cultivar pero al tener un periodo de floración algo más largo, hay que estar pendiente de alimentarlas bien, gracias Agrobeta en mi sala es posible. Temperaturas máximas en 24 y mínimas en 20 y una humedad estable en torno al 36%. Las mantuve 10 semanas pero facilmente si se quedan 11 tampoco estaría mal, yo las vi bien maduras y ya tenía tricomas ambar así que les di matarile. Os comento que tengo un descuento y para que compréis en la web de Zamnesia de un 20%, el código es ZAMMIGD2023 The discount 20% and the code is ZAMMIGD2023 https://www.zamnesia.com/ Agrobeta: https://www.agrobeta.com/agrobetatiendaonline/36-abonos-canamo Mars hydro: Code discount: EL420 https://www.mars-hydro.com/ Espero que disfruteis este diario, buenos humos 💨💨💨

These ladies are developing very nicely, the left and middle one already started to bulk heavily over the course of the last week, while the one that got wind stress is trailing a little behind and will probably take a little longer. For the other two I would guesstimate that I can start flushing by the end of the week. The trichomes on the two are completely milky, however with no signal of amber yet

Day 50: Water intake is 150ml per plant, light schedule 18/6. Humidity is approx 50%. Fertilization continues the same way Monday, Wednesday, Friday Biobizz family, Tuesday, Thursday, Saturday bat guano and Epsom salt. Flowers are developing nicely and getting thicker. Plants love the new 600W Viperspectra:) All good so far! They are all approx 30-35 cm. Day 53: Smell is getting stronger, really nice mix one. Day 55: Nice smell comes out from this tent. Plants are nice buds are getting dense and the smell is getting stronger and stronger. All of them do well, some more some with less bud development but they all look happy.

First week of flowering for the girls. We started with some master bloom from Xpert nutrients and continue with master root also from xpert nutrients. We placed a net above the poants to guide some of the taller branches and create a more equal canopy. We defoliated some lower leaves and for the rest it looks quite good, some plants showed a little sign of overfeeding so we lower the dosis this week.
