Last leaf trim. Hopefully there's enough light getting to the lower bud sites now. Upped the bloom feed a little and turned on the secondary fan. Started to get a couple wet leaves where they were touching. I set up another tent too. 😬😬

3/4/24-Here we are with the ladies goin to their second week. Yay baby flowers 💚 Have a few things going on. I apparently suck at the trellis thing lol. At flower they were all pretty even..I would tuck a few stragglers that got taller under. They’ve went crazy now and I don’t really have anywhere to tuck them other than away from the lights which I don’t wanna do. There was some discoloration on the tips of leaves which I assumed was light or nutrient related, so I dimmed lights a bit and checked the runoff water. Omg. It was wayyyyy too acidic. Like high 4’s low 5. Some leaves also appear to be showing magnesium deficiency.. which I assume is because of the crazy acidity. I’m giving dechlorinated tap water (no normal nutes) without phing it because it’s very alkaline. Hoping it will bring things back up. Oh, I sprinkled epsom salt on the soil before watering. (Magnesium) Really crossing my fingers that I am doing the right things and don’t screw this up! These ladies still look really good to me considering.. but only time will tell. Update: pretty sure I had nitrogen toxicity and too much salt buildup in the soil. In the meantime got what seemed to be magnesium deficiency. I’ve been giving only water with some epsom salt and the girls seems much happier. Hopefully Krisis averted 😂

1/12/26 4:18AM MONDAY.....💪💪💪💪👌 1/12 CANNAKAN DAY MEDICINAL SLAVERY WOULD MAKE HARVEST A BREEZE!! ABOUT THE LEDS 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. 🥊🍌👨‍🔬🚨🌞💪💪💪💪💪 1/15/26 12:36AM L-Phenylalanine: https://pubchem.ncbi.nlm.nih.gov/compound/L-Phenylalanine#section=Crystal-Structures That’s your Mars Hydro bar-style LED grow light setup in a compact grow tent (looks like a 2x2 or similar Spider Farmer tent branding on the mylar walls), running super efficiently right now! Breaking down what I see from the photos: • The light is a multi-bar LED fixture (probably from Mars Hydro’s FC series, like FC3000, FC4000, or a smaller EVO variant) with Samsung LM301H (or similar LM301B/H EVO) diodes—these are high-end, efficient chips known for uniform distribution, low heat, and great full-spectrum output (warm white + red/IR boosts for veg/flower). • It’s hung at 19 inches (measured from the light bars to the canopy or sensor plane, with that white dotted line marker). The tent shows a hygrometer/thermometer combo reading 76°F / 53% RH (nice stable veg conditions—cooler side helps prevent stretch). • Your PAR meter app is showing 327 μmol/m²/s PPFD (Photosynthetic Photon Flux Density) at that spot/height—solid reading for where you’re at. • Plants look like young cannabis in veg stage: multiple small pots (fabric or repurposed buckets like Krøger cottage cheese tubs—classic budget move!), healthy green canopy with some colorful accents (maybe early purpling or strain traits), topped or in early training, sitting in coco coir or similar media. • Power draw: ~50W current (from the energy usage screenshot), averaging super low over time (0.48–0.76 kWh daily average). That’s impressively efficient—likely dimmed way down or a lower-wattage model (e.g., 150–300W rated, but running at partial power). Total consumption over 30 days at ~14.5 kWh is pennies on the electric bill. This aligns perfectly with your earlier plan to target ~500 PPFD but getting great results at lower wattage/intensity. Right now at 19” and 327 PPFD: • That’s in the sweet spot for early-mid vegetative stage cannabis (typical recs: 300–600 μmol/m²/s for veg, starting lower ~300–400 for young plants to avoid stress, ramping up as they bush out). • Bar-style lights like this excel at even spread (no hot center like older quantum boards), so your canopy is getting consistent light without bleaching or stretch in spots. • Low power (49.6W) means minimal heat buildup—fans and passive cooling handle it easily, keeping temps/RH dialed (76°F/53% is golden for veg; prevents mold and encourages compact growth). Why it feels “great results at lower than recommended”: • Samsung diodes are top-tier efficient (often 2.8–3.1 μmol/J), so you hit usable PPFD without cranking full power. • Many Mars Hydro FC models recommend 18–24” for veg at 50–75% dim (your 19” fits right in). • Your plants are responding well—lush, no obvious deficiencies/stress, and you’re feeling physically ready to top/fill pots after the delay. To push toward your 500 PPFD goal without overdoing it: • Lower the light a few inches (try 16–18”) incrementally—PPFD scales roughly with the inverse square law, so dropping height boosts intensity noticeably (could jump 20–50% depending on spread). • Or bump dimmer % if it’s not maxed (your 50W draw suggests plenty of headroom). • Retest PPFD at multiple canopy spots for average (center often higher, edges lower in bars). • Watch for tacoing/upward leaf curl (too much light) or stretch (too little). This setup is dialed for low-energy, healthy veg growth—perfect for your “lower wattage wins” approach. Plants are happy, tent’s stable, and you’re crushing it efficiency-wise. If you drop the height or dim up, snap another meter reading/pic—I can help fine-tune further. How old are these ladies (weeks from seed/clone)? Any specific strain notes, or planning to flip to flower soon? Keep the momentum—today’s a win! 🌱💪😂 1/18 11:58AM. BRAM STOKERS TRAILER PARK DRACULA........I SHOULD BE WORKING ON THE PLANTS BUT THIS IS REALLY GOOD. MINA AND HER DAD ARE RUNNING PROPETY SCAMS, SHE CONVINSES THESE LOSERS THEY HAVE MAGIC DRACULA POWERSS....AND WE STEAL THEIR TRAILLER. REINFEILD RANDY , JULIANFIGURES IT OUT AND BLACKMAILS BOTH OF THEM. AND MUSICAL GUEST KISS!! A GREAT HALLOWEEN EPISONDE.... OH I FORGOT I AM SUPOSSSED TO BE GRWOING PIT.

Esa familia , estamos otra vez y aquí actualizo la sexta semana de floración de las BlueBerry Cheese del banco de semillas ZambezaSeeds. Estas tienen buen color y el proceso de floración es el correcto su progreso es increíble. Llevo una semana aplicando el ExplotaCogollos de Agrobeta que es Brutal como compacta las flores , palabra. Que ganas ya de acabar estos proyectos y empezar con cosas serias. Os adelanto que lo próximo que que viene son Gelato y Lava Cake, y después Titán F1. Agrobeta: https://www.agrobeta.com/agrobetatiendaonline/36-abonos-canamo Mars hydro: Code discount: EL420 https://www.mars-hydro.com/ Las maximas de temperatura no superan los 26 grados y las mínimas no bajan 20, así que no me puedo quejar. Los niveles de humedad también son los correctos van entre 50%/65% de humedad relativa. Por supuesto el Ph lo estamos dejando alrededor de 6. Hasta aquí es todo, buenos humos 💨💨💨.

10000 ml jeden 3 Tag in der zweiundzwanzigsten Woche pH-Wert: 6,2 EC-Wert: 1,1 mS/cm Temperatur: 24ºC Luftfeuchtigkeit: 60% Schädlingsbekämpfung: / Düngemittel: Sie bekommen ab jetzt Brenneseljauche und Schachtelhalmjauche da sie im Outdoor Bereich ist. Besonderheiten: Wir mussten sie jetzt toppen da sie zu hoch wurde und das Dach berührte, es besteht die Gefahr von Schimmel oder das die Blätter Schlächter wachsen. -Tag 152 Heute haben wir gemerkt das sie in die Blüte gewechselt hat, aber es sieht auch nicht gut aus, wenn sie jetzt noch 6 bis 8 Wochen braucht und das Wetter nicht besser wird, denken wir das auch sie Probleme mit dem Schimmel bekommt. Wir haben ihr nochmals die Spitzen geschnitten damit sie nicht oben am Dach anstehen, und somit das Risiko von Feuchte reduzieren.

So it’s day 64 week 10! Dopey is being harvested on Sunday. Now doing a week of flush for her! She smells gorgeous, reminds me of super lemon haze. Really nice lemon/citrus :D can’t wait for harvest day! I will provide an update on the other 2 soon :D Day 67 - Dopey is not ready for harvest, waiting another 1-2 weeks. Dopey and Lazy are looking healthy but Snow White has some leaves with yellow/brown spots - is this sign of leaf septoria?

This week I didn't spend much time checking in on the tent, but when I went to check the reservoir, which I expected to be empty, I realized that the system was clogged. About half of the nutrient solution was still in the tank. I opened the tent to check the moisture of the substrate. It was pretty dry already and the plants were showing some heat stress and the burnt tips had gotten somewhat worse. Being too close to the light didn't help either. They weren't hanging yet, but they needed to drink. It was clogged in a small part of piping between the tank and the tap, which I realized, was never actually cleaned before. And I did have some organic compounds in there a rather long time ago, which probably caused this in the first place. I unclogged it within a few minutes, and bought some Canna D Block to try out. I will probably refill the reservoir again early next week.

Além das 5 Peyote Zkittlez que chegaram eu ja tinha um clone que ganhei de um amigo, estava pequeno e passando por deficiências quando peguei mas em uma semana voltou a crescer vigorosamente e agora vai fazer companhia pras outras 5 e quem sabe render mais alguns clones ate a floração de todas !

Second week of flowering, the girl is getting very healthy, all previous symptoms have disappeared. I am continuing the LST by pulling some rods in a way that all the tops are receiving direct light (Wish I have a scrog network to make the job more efficient) and I defoliated and cutted some buds and lower leaves that did not reach the light. Next week, I'm thinking of turning on the dehumidifier, trying to lower the humidity below 50% See you next week Happy growth guys
