So many new nodes coming in after LST and topping, starting to become a sea of leaves. I am experimenting on all 4 with different training types in order to see which gives me the best result in my set up. The largest I gave LST and topped the 6th node, gave one only LST, one with only topping, and one with no training. Getting pretty hyped on what’s still to come

well we are through the stretch and fully into the flower now. They look really nice, I hope I have enough P and K in the soil, I may need a Banana tea halfway through but only time will tell.

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! 🌱💪😂

On day 1 the girls are doing well. Many preflowers showing and the plants are stretching a little every day. On day 2 the reservoir is almost empty. The plants are praying and growing well. On day 3 I changed out the reservoir. I also lolli popped and defoliated the plants to focus energy on productive bud sites. I set up my carbon filter mixing chamber, which is a box where I feed my exhaust ducting from my grow box and have it meet up with my carbon filter in the mixing chamber, then is scrubbed and sent out the chamber. I have to do it this way because I don't have space in the grow box for the carbon filter to be hung. I'm excited to see these two different phenos, I know which one I'm leaning towards so far ;) On day 4 I defoliated once again. I also applied BTI as a fungus gnat larva preventative. on day 5 adjusted ph in reservoir to 6.1. On day 6 flower clusters are forming on tops of plants. stretch seems to be slowing down which seems soon but we will see ;). On day 7 the girls are doing well.

Dane, We all should help one another. Human beings are like that. We should live by each other’s happiness - not by each other’s misery. We don’t want to hate and despise one another. In this world there is room for everyone. And the good earth is rich and can provide for everyone. The way of life can be free and beautiful, but we have lost the way. Grow High and Give the world A smile. Have A Great Day. What n°2 is lacking is n°1 compensating, (day 11, dont know what to do ph is right ppm is right themperature is ok light is ok should be recovering within 3-4 days i hope.) roots are already grown into water bucket.(should i picture them as well?) ph lv is such a pain in the ass but grow speed is worth all the trouble in hydro. (16 n°2 still not good i placed another one next to her with luck she recovers if not another one already in place to grow) (19 all hope is lost she probably doesent make it i set replacement already so waiting for her sisters to pop out and take over) (20 it is the same water in the buckets so im a little lost why one explode and the other one not,) (21 n°2 complete reset, new water, new nutrients new clay. probably died cause to shock now)

Que hay familia, vamos con la cuarta semana de floración de estas Runtz de Zamnesia y empezamos con riegos intercalados cada 48 horas controlando siempre el Ph, que ahora mismo lo dejamos en 6.5 . Temperatura y humedad dentro de los parámetros correctos. Seleccioné de las 5 plantas, 3 , que creo que son los mejores ejemplares que por el momento están creciendo bien y tener tienen un buen color, se ven bien sanas, todo normal hasta ahora, van cogiendo forma y están produciendo una tricomada bastante seria, están increíbles. Vamos viendo cómo progresan. Hasta aquí todo, buenos humos 💨💨💨.

Hi Growmies So here we have it , the end is nigh !. After and interesting 99 Days from seed and 70 days in their flowering phase of an expected 63. It is not unusual to pass the stated times and even early harvest on occasions so I am not hung up about the timing and is another reason that I use the trichromes as a guide to the right time to pull them. The #1 has definitely reached her harvest window now with some Amber tricks now being visible on checking. She looks so sweet now and I did begin to trim her up a little before I started the update pics. I do plan on using the bowl trimmer for speed this run and will video how it goes for the next update. I hate trim-jail so will use the spinner to help. Some of the buds look a bit small low down and I expect drying will shrink them to a Nug but all adds to final yield. I am not too stoked about the overall bud sizes and suspect the products did have an effect on that outcome for me but tje quality and number are its saving grace . The #2 Lady is looking chunkier than her sister although not as big in footprint. Her trichromes are beginning to cloud now so I expect at least another week before her harvest is due #3 is the most impressive for looks and appeal for sure. , she is covered in medium sized colas amd has some of the purpled leaves that the strain is known for. She is also as frosty as hell to highlight her even more. Like #2 she needs the ripening time now so I expect next update to be the final before harvest results. It has been a simple grow with no real dramas to contend with. Thanks for riding along with me. Be well.

Greetings friends Allow me to introduce you to my first ever brand spanking new homemade self contained DWC hydroponic system. So for this small experimental cycle, I will be testing various nutritional additives and plant training techniques. I will be sure to record a daily log in order to optimize my progress. Please note I will not be including germination and drying time. Day 1 Mon, 16 July So after a few days germination and nurturing, the plants have been moved to their permanent home. I filled the reservoir with nutrients following the can a websites specific instructions. Day 2 Tue, 17 July I've noticed a small growth in height however, I had a small humidity dome which upon moving slightly damaged the leaves but I noticed some strange spots which may have been from the fertiliser. But I did follow the dosages exactly?? Day 4 Thurs, 18 July Note to self, maybe stick with clones seeing as you get straight into the vegging stage saving maybe a week or two. That and the fact they're free. Ok, so I had to completely empty all my reservoirs because I misinterpreted the CANNA websites feeding schedule. It said 0-3 weeks which I foolishly did not realise was post-germination/sapling. And also one of the smaller plants #3, actually fell over because it's roots still had not dug deep enough to feed on the reservoirs moisture. However, I almost literally saw it pop back up with a tad of rehydration. Note to self a good trick for future reference will be to fill the reservoir right up until it pretty much touches the net pot and then shrinks back down to that even 35L once I begin adding nutrients. Day 5 Fri, 18 July Ok, so I gathered a bit of Intel from my friendly neighbourhood hydroman. First off I can hold off buying the EC meter until next they enter the actual vegetative stage which apparently is between 3 to 5 internodes ( the space between nodes) until then I will be feeding them a fraction amount of veggie fertilizer and rhizotonic. Now, this swamp cooler thing has piqued my curiosity if I'm not mistaken dry ice converts to carbon dioxide which we all know plants love so, that means a swamp cooler can cool, raise humidity and increase co2? In the mean time, I was given a bag of homegrown co2 which I will photograph. This will also counter the high-temperature problems I have been having. Apparently, plants can withstand an additional 10 degrees with the addition of co2 that complemented by silica would prove to be invaluable in the summer. I will be purchasing a humidifier for my saplings soon and have decided to stick with weekly reservoirs, Peace out. Day 7 Sun, 21 July Note to self I think for my cycle if I used a short square shaped reservoirs and perhaps less litres next time with multiple net pots per reservoir and with clones I think that would greatly accelerate vegge time and thus shorter cycles in general Got myself a very good humidifier and added small amounts of vegge fertilizer to the none CANNA plants.
