another week on full dose. 3-4 weeks remaining.

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! 🌱💪😂

These clones were mixed up & are either Orange sherbet or Tropicana cookies or they could be both! Unfortunately from experience growing them before they are very hard to tell apart untill late flowering. Originally grown in DWC ,all 3 got root rot at one stage Due to extremely high temps around 35°c. Had them in a 4x8 tent, running a 6 Inch adjustable speed exhaust fan which couldn't get temps lower than 33°c in our summer heat of 40°c days & nights! Moved back into 4x4, fan works good in this size tent reduces temps 28° to 31° max. Had to cut out rotten roots on back 2 plants & put them back into veg for 2 weeks until they came good, I also took them out of DWC & put them into recirculating hydro & put back into flower. Since then they have really taken off & are very healthy & lush. The 3rd plant at the front is 4 weeks into flower this one also got root rot at a different time, but I left this one in flower. I trimmed the root rot out & have had some issues with her, I also changed her from DWC to recirculating hydro as it's more forgiving in the heat & it's how I've always grown until recently doing DWC without problems in the past. All the bigger shade leaves have turned yellow, not sure if it's still something to do with root rot or a deficiency of some sort. Just trying to get this one over the line at this point 🤞🙏 increased light wattage from 480 to 730watts running 2 viper spectra lights (250watt) inside my Mars Hydro FC-E 4800.

In start week 4 flowering! Doing well! Starting to fatten out now! The 2 smaller ones are Bruce banner and are 2 weeks behind the rest in flower!

Monday’s Blue, it looks like she’s flowering but I am not sure but I will find out very soon with this coming week, the days are getting hotter and now an hour longer. I almost lost hope, the leaves were drying out, but with time knowledge is acquired and look at her now, she does show signs of going through trauma but now she healed ad growing like the rest.

2nd week of flowering, just showed the sex almost 80% of the plants. Pruning time, alga bloom time. Try to solve the height problem betweem the using some plates.

Week 11 of flower and these lady’s packed on some weight the largest 2 of 4 will be going into 48 hours of darkness today for a chop Sunday the topped plant and one that had salt damage I’m going to let go for a couple more weeks If ya like leave a 👍

Hello everyone week 2 of flower has passed for this Skywalker haze auto 💥 Mars hydro SP-6500 75% have a great day and wish you all happy growing 😎👨‍🌾🏻

Welcome to Veg Week 1 of Sensi Seeds Karate Kid I'm excited to share my grow journey with you from my Sensi Seeds Project . It's going to be an incredible ride, full of learning, growing, and connecting with fellow growers from all around the world! For this Project , I’ve chosen the Feminized Photo Strain Karate Kid : Here’s what I’m working with: • 🌱 Tent: 120x60x80 • 🧑‍🌾 Breeder Company: Sensi Seeds • 💧Strain Info : 25-33% • ⏳ Flowering Time: 8-10weeks

This was the week I decided to take a look at my trichomes with about 2-3 weeks left why not see what’s in store for me. And what I saw was some pretty milky stuff with surprisingly some amber to me that just means I’m going to get some good thc levels I’m shooting for at least 22-25% thc wish me luck we are almost there final stretch

Still stretching out them girls are , hope they are almost done 😬.. I think the stretch is pretty well done and my 4x4 tent is full of bud sites wow this is gonna be a great finish I think🤘👌 I took my hps of the hangers and attached it directly to the top of the tent for more room . I have the cool tube hps.with lots of air flow so it doesn't get very hot.

The plant looks super bushy and also very very strong and happy, she's growing super fast, and she's also enjoying life man, really happy to see this lady enjoying, she has been mainlain ed by removing the main stem and allowing the 4 secondary low ones to become the main ones, after that she got topped on each main apical and that's how we have now on week 9 this beauty, a fat runtz muffin bush! 😍

So welcome to the final update prior to harvest and it’s covering Weeks 8 & 9 of the Lemon Pie Autoflowering grow. I fertilized one final time early in Week 8 at 5 mls per gallon and have been flushing with PH’d, air bubbled water ever since. They have begun to yellow out a bit and I have been defoliating as needed. All four of these lovely ladies will be chopped over Week 10 which is within the window of 65-75 days as recommended by Fast Buds. Check in next time for the final pictures, harvest info and smoke report. Coming soon…

Cheeese is week 2 and WIFIs week 4

Plants are growing fine. I'm more focusing on soil prep at this point in the season. Cheers!

14.1.25: I've been readjusting the LST. I just took all the pegs out and reshaped her. I got some new LST equipment in the mail today, have been glad to have more pegs. I got some clips too, but they don't seem to stay on 😕 I'm currently only using the pegs, I have some thicker soft wire, but I forgot I don't have pliers to cut it! Also I'm running very low on Biobizz nutrients, so that could be bad 🤞 17.1.25: I'm quite disappointed that I didn't use a 5 or even better my 10 Gallon pot for PPP2 and even PPP1. Especially the PPP2, which is the Triploid pheno. I'd love to have given her the best conditions to see the full potential! 😕 Obviously, I didn't know when I popped the beans, but it just feels like a wasted opportunity to learn, and that's hard to swallow for me. That's my whole aim with these plants. Despite my regrets in that respect, the plants are both looking great! PPP3 is literally just taking up prime real estate 😑 I can't bring myself to trash a plant, though. Plus, it's interesting in and of itself. Just being as it has stayed so small and only has 3 fingers in any of its leaves in week 10. Continuing to adjust ties and pegs as often as I can, trying not to overdo it. 18.1.25: I have done another large defoliation on PPP1 and PPP2. Also, moderate defoliation on all other plants today. All LST ties and pegs are readjusted. I have turned up the light to 90%. Same distance of between 24-28 inches, depending on height of specific plant. I have increased the dosage of Biobizz Bio-Grow and Fish Mix to give an extra boost of Nitrogen as several plants were showing yellowing. They have responded very well to this. Unfortunately I ran out of my Biobizz nutrients and PH UP. I'm currently using Bicarbonate of Soda to increase the PH after the nutes PH comes out to about 4.1. Obviously, that uses a lot and I only had a 250ml bottle, which I used last run too. This run I have 9 plants. The only thing I'm worried about is the salt build up. Have you used it before? Or any other natural way to increase PH? Please let me know! I've also added Biobizz Fish Mix to help with the extra Nitrogen needed. Watering with 1ltr of dechlorinated water PH'd to 6.3 with the following nutrients;- ♡ 4ml Biobizz Fish Mix ♡ 4ml Biobizz Bio-Grow ♡ 2ml Biobizz Bloom ♡ 2ml Biobizz Top Max ♡ 2ml Cal-Mag ♡ 2ml Ecothrive Flourish. I water with this every 3 days. I did order some more Biobizz Bio-Grow and Bio Bloom. I found some at a reasonable price on Amazon. I still have about 800 ml of Biobizz Fish Mix left, too. It is fairly expensive this time as the plants are hungrier this run. I also got a new bag of Canna coco, which I may use to add a top dress with some dry amendments. Which hopefully will save some cash on the bottled nutrients and stretch out until the end of this run without having to buy anymore. I have purchased a funnel to pour the water. It is difficult, due to the shape of my LST, to water precisely. I have spilt it all over the tent several times 🙄 I've also ordered a 2 litre jug. Currently, I'm mixing water for 9 plants individually in a 1 litre jug. It's tideous. Hopefully, this will solve the issues. Cleaning the tent after watering every time isn't my idea of efficiency 😅 Thanks for checking out my diary 🍃 ✌️

Day 12 Starting to show preflowers. Seems a bit late. I will take clones today from top 3 plants 81f/76%. 1100ppm. 1000co2 37-53kluxx 4 very sickly and ugly plants Plant stems are all pretty stiff by now. Looks like i could have fit 2 more plants Day 14 Plants are doing well with height control. I did a second Topping of the main 4 branches for each plant the week before flower flip. Most plants are 22-25inches tall 3 of my White Weddings are looking very weird. Not a clue as to what is wrong. Flowers are developing well on each plant No more LST from here in out. I will let them grow how they are(minimal stress) Started Defoliating

Here we go!
