Here we are back! Sorry i can’t update this every week, i’m low on time due work. Growth is incredible fast since they have been set in hydro. The latest girls has been topped and main-lined and auto lemon is in the second week of flower. added some bloombastic for PK (Phosphorus & Potassium). Defoliated some lower leaves as they'r growing super healthy and vigorous, I think i'll be making the 12/12 switch next week. Lights are running both at full capacity(CMH > Superlumens mode (340W) and ViparSpectra LED's (450W/200W actual power) = 540Watts/1m2

RSQ Wedding Cake has just start producing hairs but still not in flower yet. FB Cherry Cola has already started producing some Icy . SS Bruce Banner has an issue going on, I've got mixed reviews on what it could be. Added about 8ml of Athena IPM to the water for that one. Hopefully she snaps back and grows strong

Week 7 Flower: The High Stakes of Growing Gold As we sail through Week 7, the journey has been smooth sailing, thanks to our signature dry amendment feeding technique. But now, the stakes are higher as we transition to flushing our ladies. With rain on the horizon, the threat of bud rot looms large, adding an element of suspense to our cultivation adventure. But amidst the anticipation, one thing remains certain: our bud sites are densely packed and sticky as ever, promising a bountiful harvest on the horizon.

Asyou can see, my lil'Candyshop has got alot of sugar already! But her buds are not fattening up bc she is foxtailing a bit... It was very hot this week with temp of alomst 40C without wind.. Temp is now a bit lower.. and letshope she can get some weight on her those last weex! (next time gonna top her and do some LST.. 👍 i was a bit of a dummy by not doing that this time, being lazy i guess😳) Happy growing for all✊ ***KISS growtechnique: KeepItSimple,Stupid!

December 15, day 1, seedling healthy with taproot growing 1.5 inches out of rapid rooter. Transplanted to seedling container. Under 25w Sansi LED untill it is ready for veg lighting. 5 gallon final container prepped with buffered coco/perlite. December 18, day 4. Seedling has had some issues with transpiration, probably due to not enough flushing of the coco. The result is damage to the tips/necrosis of the first true leaves. I flushed the medium and the seedling seems to be recovering. It is sending out more roots and growing at a steady pace. I also moved the seedling into its final pot. This feels a little premature, but it was over growing it's humidity dome. In the final pot it can be covered by clear plastic to maintain humidity. December 19, day 5, new growth is healthy which I am happy about. I will cross my fingers that my quick adjustments fixed the transpiration issues. I am hoping to get it huge and have it trained across the whole 2x4 tent, and it needs to avoid getting stunted for that to happen. 💪🌱 December 20, day 6, I had a bit of a scare when I accidentally knocked my humidity meter and it fell right onto the seedling! The poor thing was knocked right over. It seems to be fine, just leaning a little bit over which will hopefully correct itself in the next few days. December 21, day 7, healthy growing 🌱👍

Autos are just starting to flower the photos are dying for some bigger pots. I've been trying to bring up the overall plant health in general since moving everything to a basement the temps are a little lower than ideal. I had a space heater delivered today and monitored the temps but they only went up to around 78°f I want it to be atleast 82°f ideally 85. The heater uses 1500 watt and only increased it about 2 or 3°. I dont think it's worth the extra cost for such little boost. I'm thinking about returning the heater and throwing a 1000w hps in one of the other tents and see if that will raise it anymore. Especially with LED and co2 higher temps would be very beneficial in veg and early flower but the room is so big its gunna be tough to pull off without killing me on electric costs. Any suggestions are welcome. I know this room does decent in flower but I havnt done much veg work down here and I'll have some autos growing this round so it's important I get it up.

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! 🌱💪😂

Day 36 1/13/25 I think she is taking to the location okay so far and after the first cut I did I’m not sure what I’m doing I’m just doing my own little mainline thing experimenting I guess I’m using APSU super soil and a little bit of build of soil 3.0 left from last grow and it’s a 7 gal pot als 1/14 day 37 Did second and final topping going allow about two weeks to bounce back and allow more growth and LST then flower
