May 24th - Day 97: It's amazing to see how well the babies have recovered. Unfortunately, two of them have pretty much died, but hey, more space for the others to grow! Humidity is still quite unstable because I increased the frequency of watering, but it will be fixed soon. I will update on Sunday. They're drinking really well, about 60L every 2 days for 10 plants. I need to figure out a bigger container to hold enough water for a whole week.

😞😞😞 mes 2 plantes sont devenues hermaphrodites 😞😞😞 Remarqué ce samedi, une dizaine de poches à pollen dont 2 déjà ouvertes. Certainement un stress mais lequel...?? Fuite de lumière, un coup de froid,...?? Vraiment dégoûté 😞

June 8: really cold here the last few days. Likely due to the heat dome now in SW states and Mexico. Overnight low of only 1 C tonight so the plants are indoors until conditions improve which should be soon. June 9: it wasn’t as cold as forecast last night and stayed above 5 C with lowest being two nights ago at 3.3 C. Watered with 26 C water this evening to keep it warm a bit longer but overnight temps should be fine again now and she’s outdoors full time now. June 10: watered this morning with first compost tea. Pic is from the evening and she’s looking really good. A few days ago I forgot to lower the pH of the city tap water and the biggest fan leaves show some of that pH swing damage. Oops. Looks good now though after the lazy compost tea. Lazy compost tea is compost, molasses, some coco coir and some Monster Maxx. Let sit overnight but not so long that it goes anaerobic. It should smell fresh not sulphurous. June 11: looks good after the compost tea. June 13: to get the stems growing apart in preparation for another round of topping, I supercropped both stems, taped with floral tape, and then tied down using pipe cleaners and paper clips on the edge of the grow bag. Nice run-on sentence there. #seedsman420growoff #seedsmanseeds

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! 🌱💪😂

Throughout the growth of the plant communicated, from the seed it is a strong and healthy plant. I did LST training, topping and defoliation on it. Finally, it also has a quality harvest. Is perfect 😉

I’ll start by saying I’m NOT using both bud blood and bud ignitor in one solution, I am using bud blood on the rear wedding gelato plant and bud ignitor on the front one to test the outcome of them individually to see the best results! I tied down and defoliated twice in the week and have switched to 12-12 yesterday so they’re transitioning now and should be in bloom by week 7! I made some extract them made some gummies successfully I might add and added the photos in the diary!

Flush week begins for one of the 2 plants. Not many red pistils yet but I will be cutting in a few days as there is already quite a bit of amber color in the crystals. Definitely don't want to miss out on the nice terpenes, the smells are pretty amazing, very citrusy. The yield looks like it could be quite decent too. Buds not as thick as I was hoping for, but still really good looking. Some leafs on the right side plant showing some signs of various issues and maybe a few previously undetected bugs on some leafs, but looks like all should be good.

These are doing pretty damn good for the most part. I figured out with the green buzz the only thing in bloom that raises ppm is the base bloom and the more PK which is good to know. Also been using lower ppm for the autos and they seem healthier than usual. These pics and the video were taken on Day 36.

Great week! She has been gaining all week, and is going to make some great colas 💪 I upped her nutrients again this week and still she looks like she could use more. I’ll be going to a regular feed, and the light feed schedule with her for the time being, no more straight water until I can see she’s producing and getting all she needs. Temps have been very high where I am, which in turn causes the tent to run a little hotter, especially with the two lights now. Hovered around 82-83 degrees for most of the week, and then came down a bit once the heat broke. No need to fill RH at the moment, tent is a nice 55%

did some LST to this girl. We were in the middle of a mini drought but we did get 6mm of rain yesterday. So that will help with growth a lot. I also watered them with a whopping 9 gal each day before the rain. So I am expecting some excellent growth over the coming week. Ive been looking for an inexpensive source of granulated humic and fulvic acids if anyone knows of a source in southern Ontario.
