1/12/26 4:18AM MONDAY.....💪💪💪💪👌 1/12 CANNAKAN DAY EDICINAL 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! 🌱💪😂

9/27 9AM Water only abt 12oz each plant. #1) 1 1/4" #2) 1 1/2" #3) 1/2" #4) 1 1/2" 10PM Started a White Widow Auto seed from HGCC in 20ml Distilled water to take the tent space of my #3 Devil Auto.

Si vola💪🏼

I've no idea what is wrong with this plant. It's like it's diseased, all the leaves are wrinkled. One leave has decided to only grown on one side? Perhaps it had an argument. I've moved the light away but it's not looking good so far.

Hey there growers!! Sorry for skipping flower so bad.. here are some videos of the ninth and tenth week. No excuses, but someone stole from me back then and I didn't feel like making videos for a couple of weeks. But the experience went on, the female plant reversed and it's pollinating itself with my help like you see in the videos. Sorry again for the Spanish audio 😅

We are in Flush !! Was giving them GH Flora series + rapid start + cal mag

Thank you so much Molly and Heather and all of the fast boats team for giving me the opportunity and setting this up for me so I can have some of the best genetics in my garden ztrawberriez auto Is an absolutely beautiful plant. I recommend it for everyone.🔥💯

Did a good bit of defoliation and a little more LST this week, also added in a Co2 canister. Still a pretty easy grow overall. The watering has increased but its expected around this time. My main focus was cutting a few of the unneeded fan leave and the small popcorns at the bottom to focus growth on larger bud sites.

Hey Growmies, All three of the ladies are developing as they should. Introduced sugar Royal to the mix, so far don’t see a difference, but the plants appear overall very healthy. Increased the ppfd to 269-300 as they grow larger. Here is the code that’ll give you 20% in Zamnesia‘s online store, just input ZAMMIGD2023 at checkout. Thanks for stepping by and until next week!

6/16 today was a feed day. Transplanted into 20 gal rain science mesh pots 6/19 today was a tea day. applied some LST clips to try and stretch her out more wide

The weather's finally starting to warm up. It feels so good to have the sun out and to open the windows. With all this extra sunshine, my pound cake plant is really taking off! It's growing so fast, and it's starting to look really full and healthy. I can almost see tiny buds on the ends of the branches - maybe it'll even have flowers soon!

2018-11-19 Flowering in full swing. Pulling slows down. In the morning, on the day of the compote replacement, my PPM-meter broke down. Therefore, the new solution was kneaded by eye. Tomorrow a new device will arrive and I will clarify what I have mixed there. 2018-11-24 Buds swell, there is time to figure out how to do time lapse video.

Used too much bloom nutes and some top leaves were starting to yellow so I flushed and have Been gentle since Few days later it was t from nutrients it could actually use a little more the lights I have were putting 1700-1800 ppfd on top canopy and was cooking my leaves I lowered the plant so it would get 1200 ppfd on top and it’s back to normal

Hi Growmies, I'm excited to share some big news today! Although there have been some unexpected twists, it's all part of the incredible journey of gardening. I've just completed the harvest, a tad earlier than initially planned, due to finding a bit of mold in one of the buds. Despite this minor hiccup, the trichomes were already at a decent 10% to 15% amber. So, all things considered, the timing ended up being pretty spot-on. The harvested weight was a solid 609 grams after trimming, which is quite a feat! A lesson learned for next time: perhaps I let her grow a few too many buds, leading to a denser canopy than ideal. But on the bright side, the aroma is absolutely divine. I sampled an airy bud that had dried a bit, and wow, it packs a stronger punch than its clone mother. And the flavor? Pure, unadulterated cheese – no hint of pineapple here! Now, the anticipation builds for the final dry weight, which I should know in about 3-4 days. It's always exciting to see the fruits of our labor fully realized. A huge thanks to everyone who's been following along on this journey. Your interest and support mean the world. And now, the adventure continues! I've started on Epic Buzz by Anesia Seeds. The diary for this new chapter is up and running, and the seedlings have already sprouted, marking the beginning of another exciting phase. (https://growdiaries.com/diaries/185718-grow-journal-by-salokin) I can't wait to share more updates with you all. Here's to the continued growth and learning in our gardening adventures!
