first day after a 12h night cycle, still have a big gnat problem. gonna go buy new bacteria, stickies and DT Earth. the grow shop just let me know that they got it back in stock but i haven't been able to find nematóides. doesn't seem to be a common practice here. i haven't watered them in a few days. the top soil is bone dry but the plants don't look like they're requesting water just yet so i think it's a good time to lay down the new dt earth and new yellow traps to see if we can kill the remainder. gonna grab some flowering ferts too while I'm at it. Update: got a bigger pot and some supergrow soil, only had time to transplant one of them today. but I decided to after them one more cycle before i do the DT earth. update: dt earth added, seems to be alright but not quite dry enough

Welcome to the Sweet Seeds Cup 🏆 Hey everyone :-). This week she started to put her full power into the flower production :-). Since then she has received Canna Bio Flores and Canna Bio Boost 🤗. It is barely one meter high and looks beautiful 😍. In addition, it starts to smell very delicious 👍. I water it about every 3 days with about 1 l - 1.5 l. It is very stable genetically and I'm glad I took cuttings 😅 . I am very curious to see how it will develop next week. I wish you all a good start into the new week, stay healthy 🙏🏻 and let it grow 🌱 Sweet Seeds Cup 🏆 Type: San Fernando Lemon Kush ☝️🏼 Genetics: OG Kush x Kosher Kush 👍 Vega lamp: 2 x Todogrow Led Quantum Board 100 W 💡 Bloom Lamp : 2 x Todogrow Led Cxb 3590 COB 3500 K 205W 💡💡☝️🏼 Earth: Canna Bio ☝️🏼 Fertilizer: Canna Bio ☝️🏼🌱 Water: Osmosis water mixed with normal water (24 hours stale that the chlorine evaporates) to 0.2 EC.

Day 63 Well there’s not much going on. Just watering when dry. They seem to be doing better, but unfortunately the damage was done with the lockout. They are fattening up a bit more and putting on some density. I can tell by the fact that they’re leaning more. This is a 10 wk strain, but I’m gonna push it a bit longer til the trichomes are in a better range. They have a sweet blueberry smell which is quite nice. Not the frostiest buds ever, but we’ll see how it shakes out. We’re just on autopilot til the end. Probably a week or 2 more and they’ll be ready to come down. Happy Growing 🌱

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! 🌱💪😂

Well My friends gave me a bigger tent so I got a little more time to let them develop! I'm very ready to take them down just waiting a bit longer for a few more amber trichomes. I'm still feeding them ripen but i wish last week i'd given them a feed in addition too. They look nice in the new tent, there is loads more room, and while the lighting didn't go up as much as I'd like, They have a nice big fan oscillating on them now and room to stretch. ________________________________________________________________ I suppose I'm glad I waited. I wanted to take a few more pics and get one last video in! I'm def seeing a bit more amber in the trics and i think it will make em a bit better for these 2 extra waterings! Probably gonna chop them soon!!!!

Week 9 is here and we are looking at harvesting! After checking the trichomes of just the top colas, I decided this week I was going to harvest. I am updating this post after I have dried and harvested the plant so do not have much more details. I flushed the plant this week with Flora Kleen along with terpinator and microbes. I cut down the plants and hung them up in the tent to dry using a clothes hanger with clips I got off of Amazon. It took 10 days to dry the bud and my temps and humidity would fluctuate throughout the day and night. I stayed in the mid to low 70s for temperature and humidity was at 50% at first. Then I added a humidifier and had it dry in 60% humidity. Will update the rest in the harvest update.

Que pasa familia, vamos con la cuarta semana de floración de estas Kiwi x Papaya feminizadas de Mavericks . Vamos al lío ,se trasplantaron en macetas de 7 litros definitivamente. El ph se controla en 6.0 , la temperatura la tenemos entre 24/20 grados y la humedad ronda el 50%. El ciclo de crecimiento puse 12h de luz, el foco está al 80% de potencia. De momento van creciendo a buen ritmo y tienen un buen color. La flor está cogiendo forma y ya empezó a tricomar. Gracias a Agrobeta de nuevo por el kit para esta temporada, unos grandes 🙌. - os dejo por aquí un CÓDIGO: Eldruida Descuento para la tienda de MARS HYDRO. https://www.mars-hydro.com Hasta aquí todo, Buenos humos 💨💨💨

This week I added 9 ml of nutrient per gal of water to prepare for switching to flowering. Grow 5 inches this week getting ready to start flowering. I lowered the light to eight inches which really had these plants growing faster and thicker.

This week has been great for these massive girls i still stand by saying they would do amazing outside somehwere with lots space or a big grow room. 2 buds have grown so far they damn near touching the light. I am going to leave them see what the light does to them. The 1s that are insane close like 1 or 2" are compketly covered in resin sooooo if i can have a even canopy and lower that light ontop of them........ hmmmm curiosity may kill some shit. Didnt say "cat" personalsmoke just for you. They are getting heavy dose of nutes at 5.6-5.7 ph started the pk 13/14 train wooowoooo Sooo stinky sooo sticky yummy yummy Kelp ur head up 😄 Love yall

Let's talk about our Jealousy girls from Zamnesia Seeds. We have one Jealousy (1) at 15 weeks and another Jealousy (2) at 14 weeks. Jealousy (1), nicknamed 'the first,' has been on a water-only regimen for two weeks now. For the past three days, instead of regular watering, we've been adding ice to her pot to give her a little stress. Meanwhile, Jealousy (2), or 'the second,' is still enjoying her nutrient diet with TDS at 1800 ppm and pH at 6.2. However, Jealousy (1) has started showing signs of yellowing leaves and around 30% of her trichomes have turned brown. We're planning to harvest Jealousy (1) by the end of the week on March 3, 2024. As for Jealousy (2), she's still growing strong!
