D33 - 19/02 Haven’t changed the reservoir this week yet. A few burnt tips on Northern Lights #2, will probably go a little lighter on nutes next feed - she’s definitely more sensitive to them than the other ones. Overall great looking girls and nice growth. The #2’s are higher than the #1’s, nodes developing nicely and the scrog is definitely helping with lateral growth as well. — D35 Mixed a new reservoir with roughly 19L, at around 70% strength. pH 6.0 and EC 1.1 Humidity has risen a bit, so I installed the dehumidifier again. Apparently the tip burning has stopped, or at least slowed, which is good. #1’s are at around 25cm height, while #2’s are around 40cm height. — D36 Did another defoliation session as the girls really needed it. Cleaned a lot of the big fan leaves, airflow and light penetration is way better now. A few hours after and they’re super happy again.

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! 🌱💪😂

Hey guys :-) . Today the plant was sprayed again with neem oil. There weren't any more trips to be seen after the second application, but to be on the safe side, you did it again today get a cure. That's why the beautiful dark shimmer on the leaves :-). The ladies are developing well and have 1 week before I change the time to flowering. Normally I would let it get bigger and train because the tent only has 80x80 and 180 watts are available, so I will switch it over soon enough. This week it was poured twice with 0.8 l each time (for nutrients, see table above). Otherwise everything was cleaned and, as always, everything was checked. Have fun with the update and stay healthy 🙏🏻 👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼 You can buy this Nutrients at : https://greenbuzzliquids.com/en/shop/ With the discount code: Made_in_Germany you get a discount of 15% on all products from an order value of 100 euros. 👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼👇🏼 You can buy this strain at : Clearwater Seeds Water 💧 💧💧 Osmosis water mixed with normal water (24 hours stale that the chlorine evaporates) to 0.2 EC. Add Cal / Mag to 0.4 Ec Ph with Organic Ph - to 5.8 - 6.4 MadeInGermany

So it has begun... I've had to start utilizing string to hold up branches by tying them to the ceiling rods and surrounding equipment. These plants are healthier and happier than my first grow, so I wasn't quite expecting them to blow up like they did, therefore my single-layer screen was not enough to support the branches. Not to mention the net used was store-bought and kind of sucks. I prefer my double-layer from the first harvest. The Mimosa is packing on some major frost, followed closely by the Glookies. American Pie trichomes seem to appear and ripen much closer to the ending stages of flower.

Second run with these genetics, I ran her last time in a 5.4 gallon container, I got the grape pheno, higher yield with the first run, but much tighter nugs with this run. This one smells much more earthy/gassey and less grapey. I ended up with just under 26 zips of nugs, 2 zips of Larf which I will turn into canna sugar, and my buddy made a 35 gram brick of bubble from the trim. It should be dry in the next few days and I'll post a video of the squeeze, hoping to get around a zip of rosin which I will split with him since he turned the bubble...Super excited to squeeze some nugs once the cure is done, Ill post vids of them as wel. Next run I'm planning to try and cram 2 plants inside a 5X5, build mainlines, and flip by week 6 or 7....Switching to two 315 W CMH bulbs up top, and LED's on 2 of the sidewalls for supplemental lighting. Looking forward to it, stay safe, blaze on!

Very compact and bushy, trimmed the crap outta her to get some air flow so she can start getting some height. I'm pretty sure I over fed in the beginning and at the end of my troubles hopefully, and she will start filling out properly.

Gorgeous looking plant, very thick and dense main cola which is gonna hold the 70% of the weight, however the secondary branches develop dense fat and compact flowrs as well, I would love to apply LST on this strain by gea seeds when I grow her again because I think I will. Follow me on this journey, let's see how this lady performs!!
