Hey guys and welcome to start of Week 8! 🌻 Today is day 21 of flower so i went ahead and cut most of the plats Fanleaves off. It took a while but now the Airmovement is improved and the humidity should also be lower. I also hope I didn‘t stress them too much. From now on they will be reseaving less and less Nitrogen going forward. I hope the colours come through as well 🤞🏻 Thanks for following along and I will keep updating the progress. Happy growing 🍀

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! 🌱💪😂

I had to harvest both sbc.. they produced seeds caused by too high EC in the Coco. The EC of the GP was even higher but she seems to handle it better and performs normal. A EC of 1.8 in the Coco was too high for the sbc. EC of the GP was 2.4. I flushed the GP, it was now possible since the sbc wasnt there anymore and therefor was no danger of getting the stacked pizza boxes wet which would let the sbc sink down like in mud. GP will be harvested in two weeks and right after that i will start a new diary with 3x sbc. I then can flush probably and will not run into this problem again.

Lotss of updates! Got a decent commercial LED 600w so just about same wattage as my last three lights but way more coverage and light penetration🙏 I dont have the dimmer so that might be needed as the babies get taller! Ended up cutting about 6 clones from each plant. Just going to wait for a little recovery then im transplanting into 5 gallon for flower!

Día 22 (11/11) Las plantas muestran pequeños puntos / zonas marrones pero... Don't panic! It's Organic! Dejaré que el proceso del Super Soil de BioTabs siga su camino tal y como indica el manual de BioTabs! Ajusto LST a CBD Auto 20:1 #2 aplicando una nueva atadura a la punta, que ya se estiraba hacia arriba 24 horas después! 💥😍 La idea es NO aplicar más LST y dejarla que crezca de forma natural a partir de ahora Tal vez solo ir recolocando las ramas laterales para que no crezcan demasiado juntas, porque no quiero estresarla y que ralentice su crecimiento... Día 23 (12/11) Subo a DLI 40 Pequeños ajustes de LST en las ramas laterales a CBD Auto 20:1 #2 para crear una estructura homogenea No voy a volver a aplicar LST a la punta, voy a dejar que crezca de forma "natural" a partir de ahora El resto de plantas están creciendo muy bien! Riego con 750 ml H2O RO a CBD Auto 20:1 #2. El resto no necesitan riego Día 24 (13/11) Riego todas las plantas con 750 ml H2O RO CBD Auto 20:1 #2 se muestra sedienta y vuelve a necesitar 750 ml de H20 RO tras solo 24 horas desde el último riego! Día 25 (14/11) Pequeños ajustes de LST en CBD Auto 20:1 #2 Parece que los puntos / zonas marrones se aceleran en todas las plantas excepto en CBD Auto 20:1 #1... Día 26 (15/11) LSD-25 Auto & OG Kush Auto empiezan a mostrar muchas zonas marrones y las hojas inferiores se empiezan a retorcer... Día 27 (16/11) Riego con 1 litro de H2O RO El area técnica de BioTabs me confirma que lo que muestra las plantas es una quema de nutrientes... 😢 Su recomendación es regar SÓLO con agua la siguiente semana (hasta el día 35 por lo menos) Día 28 (17/11) LSD-25 Auto & OG Kush Auto se muestran muy afectadas por la quema de nutrientes... Una pena porque estaban creciendo muy bien hasta ahora... Después de hablar con BioTabs, parece que el error ha sido aplicar el Boom Boom Spray demasiado temprano (en día 21) cuando las plantas tenían suficiente nutrientes y acababa de añadir la 2ª (y ultima) Tab al sustrato... Tengo que seguir aprendiendo que con el SuperSoil: MENOS ES MÁS, MENOS ES MÁS! A seguir regando SOLO con agua los próximos días... CBD Auto 20:1 #2 todavia no muestra el sexo (pre-flores)... es algo extraño... 💦Nutrients by Bio Tabs - www.biotabs.nl/en/ 🌱Substrate PRO-MIX HP BACILLUS + MYCORRHIZAE - www.pthorticulture.com/en-us/products/pro-mix-hp-biofungicide-plus-mycorrhizae "GDBT420" 15% DISCOUNT code for the BIOTABS Webshop https://biotabs.nl/en/shop/

First day of week 6! Looks like what transplant shock I was afraid of never materialized so that's a plus. I did however discover 2 things that have been bothering me. The first was random discoloration and spotting on some leaves, I had no idea that it was due to me spilling watering nutrients on the leaves, so I dug a small canal around the main stem of the plant. Now I just pour water evenly around the canal. The second was, why is my plant so small. Most other Blue Dreams I've seen seem to get really tall and stretch upwards. Mines just seems to get bushier. After more and more research, and probably one of the most obvious things to more experienced growers, is that it's not stretching so much because it doesn't need to. So at least my light is on point. I watered regularly today for the first time since transplant, but only used a quarter of a gallon.

This week, my Titans are sleeping in a cooler dark room until harvest. So for your viewing pleasure, I've loaded some videos made of the Titans during there time with me. I'm wondering what to serve at my Queens Tea Party... I made some butterscotch pistachio bars and modified the recipe for less sugar. 😋 We experimented with topping the bars with black cherry spread, orange marmalade and a mango jelly. All are very tasty as the bit of sour/tart enhances the butterscotch sweet. A few solar eclipse pics.

the seedlings germinated on September 22 in the biobizz light mix soil after 13 days I administered 1ml / lt. advanced nutrients ph perfect grow 1ml / lt. ph perfect micro 1ml / lt. 2ml / lt. b-52 2ml / lt voodoo juice after 4 days I repeated the fertilization with 1.4ml / lt of the main nutrients and 2ml / lt of b-52 after a few days I noticed some burnt tip signs of overfertilization so from day 12 I started giving demineralized water until the outflow for 3-4 times until a few days ago that I noticed a yellowing of the upper part and spots that look like calcium or potassium deficiency I was also wondering if I can do without the cal-mag since the ph perfect micro contains a lot of calcium. tomorrow I give the third dose of nutrients hoping they will recover since nothing has changed with the first two fertilizations Days 39 they do not seem mileage even after a week of fertilization even if at very low dosages the next time I increase the nutrients and let's see what happens Days 41 it looks like it's going well they still look nutrient deficient the next time we increase the dosage.

3. Woche Blüte beginnt Sonnig, aber die nächsten Tage soll es wieder kühler werden, naja dafür aber weniger Regen und mehr Sonne. Also bis jetz bin ich zufrieden wie die gute wächst und hab gute Hoffnung das das erfolgreich wird. Die Blätter um die Blüten werden langsam auch "frostig" 😁 hoffe wirklich das ich die noch anständig bis zum ende durch bekomme und ne anständig und hoffentlich schmackhaft Ernte einfahren kann. Riechen tut sie auf jeden Fall hervorragend und auch ordentlich also is schon en kleiner stinker der deutlich wahrnehmbar is 😅, bis jetzt sind aber noch keine Beschwerden gekommen. 53. Tag komplett auf die 2ml/l Organic Bloom laut Plan gegangen. 55. Tag Die Blüten werden immer praller und trichome auf der Blüte und den Zuckerblättern sind schön zusehen 💎🤩

The photo plants are still growing a bit but think flower is a week or two out. Preflowers starting show but had to chop one more male. Increased bloom nutrients this week but still going light. Reacted well to the defoliation of the lower branches last week. Wish I had bigger pots. The 15 gallon smart pots are maxed out. The plant in the pink pot is about 6'4" now and still growing the most. Chopped shorter auto Sunday. Did a wet trim but still plenty to trim later. Chopped half of the other auto Tuesday but the lower buds still have 3-4 days to go. Excited to see the yield from both plants.

Soo I’m not holding my breath but it actually seems like she’s just gone into flowering ! Properly! I had the chop the top of the main stem :(it just got too big for the little greenhouse I have. Maybe that’s what pushed her to flower. Who knows 🤷‍♂️ Outside temp is perfect. Did some defoliation and extra lst on her so that there is light throughout.

Another strong week here. The blumats are working well at this point so the girls get adequate water intake. They continue to develop and the fade has now started. Will be looking to chop some of them next week.
