Week eight! I will be removing the mylar and whitewashing the walls instead. Hopefully this allows sufficient light. Day 51 - photographed Day 52 - fertigated 5l each. I am thinking about starting to train these girls now, so expect updates soon. Day 54 - removed top few nodes and cut clones. Dat 56 - Photographed. If you don't already follow me on X, please join me over there, where you will find a bustling cannabis community. Thanks to Super Sativa Seed Club and the Passion of the Dutch for the beans!

Been an ok week...the plant on the right is still struggling, the clones I took off her last month have grown some and are now exhibiting the same leaf mutation and strange yellow patterns. These clones are in a completely different growing media and on a different regiment and I think they're going to be the same as their mother..idk if this is viral or simply genetic but It's been a battle...plant on the left is beautiful as ever, I'm thankful, without her we'd probably run out of bud before the next harvest in 4 weeks..

Day 86, 5th of December 2020: Craziest group I have ever had... Honestly I just want to see the end. I will be away for 2 weeks almost. Original Sensible Seeds ladies are dope. Gelato is very nice proper shape one of my favourite she is just nice and not problematic.... :) Runtz Gum is amazing nice big buds are on the way really nice! The same no problem with her at all!!!! Do-Si-Dos OG is just crazy.... She is not an easy lady... problematic... never met a plant like this one. ... Too much strech and now I need to tie and stand her up somehow i broke one branch.... I put a tape arounf so hopefully saves that bud tho....🤣 Her flowers kill her lol Black Ghost OG is sweet and good girl she is the easiest player from them she is good for begginners similar to Wedding Gelato even is shape haha.... Wedding Gelato from RQS is just perfect no problem with her at all... good for begginners as well... :) So This is how it is 5th week has started I just wanna get it done really long journey :) The lamp is now on 11 hours and off 13 hours. Every week 15 minutes was taken off and after 4 weeks here we go. Strated 12/12 and now 13/11 wanted try to imitate the nature as the light days are getting shorter. Fertilization has changed no more epsom salt from this week and I will stop giving nitrogen as well from next week.

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! 🌱💪😂

Week 5 begins for LSD and Green Crack! The LSD ladies had the most yellowing over the last week, yet they have the most frost on the buds. The Green Crack ladies had a little bit of yellowing and has bigger buds, but no frost at this time. They all seem very happy in their new 4x8 home. Thanks for stopping by growfessors, tune in next week for another episode of growfessor theatre. 👽🌳💚

Buds are getting fatter by the day swapped the to front plants round and put the short bushy one onto a water drum to raise it to the same height of the other two so i could raise the light more

Still vegging is a good sign that she can grow some more. Expect her to start Flowering soon. Excited to see what can be achieved by an Autoflower that survived frost and low sunlight hours although not expecting much yield. Will continue with biogrow and fish mix until she start flowering. Added some mulch on day 47. The increasing temperatures and African sun is dehydrating the soil too quickly and forms a hard layer which is a pain in the ass when I water.

RIP!!! This week we went up to check on her 3 days after the was moved into her new home and she was looking very healthy. Then when we went to check on day 4, SHE WAS COMPLETELY GONE!!! We don’t know what happened, however we assume that a wallaby or another animal ate her. As we are guerilla growing, it is very difficult to manage things such as pests. And our location has a lot of frequent wallabies, so it was only a matter of time. This is a very sad day indeed, but now we can learn from our mistakes and put a cover over the rest of our batch. RIP!!!

Vamos familia, actualizamos la tercera semana de floración de estas Runtz Punch de Herbies. La temperatura que estuvo entre los 24-26 grados y humedad dentro de los rangos correctos. En cuanto a las plantas las veo verde sano, estiraron bien y ensancharon bastante también. Se nota que los nutrientes de la marca Agrobeta hacen sus funciones. Las flores empezaron a formarse, por el momento todo correcto, os dejé también alguna novedad y un cambio en la sala, agradecer al equipo de Mars hydro por el nuevo TSW2000. (los últimos 5 años cultive solo con los leds de esta marca). - os dejo por aquí un CÓDIGO: Eldruida Descuento para la tienda de MARS HYDRO. https://www.mars-hydro.com Hasta aquí todo, Buenos humos 💨💨💨
