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.

The Sensi Seeds Research breeding project has created eleven cannabis seed varieties. How? By combining new cannabis cultivars with a selection of strains from their long-established cannabis gene bank. For the first time in thirty-six years, they are opening the doors of the Sensi Seeds Research and Development Department. Week #1 All seeds have germinated in 48 hours after soaking in water. The germ has grown in wet cotton for 24 hours and has grown 1 cm long. All the seedlings popped out from the soil the 02/12/19 after 48 hours in the cups. Making the germination ratio at 100%. I was a bit worried to use the Mars-Hydro SP250 on seedlings, but at 75cm following manufacturer recommendations everything looks perfect. Environment is under control, light, humidity, temperature, and airflow. Seedlings are not going looney and stretching for the light . Using only pH’d water with some RootBooster at this stage to enhance roots development. (I’m looking for a job in the cannabis industry as Master Grower, Mineralogist, Quality Control)

Week 6 begins for LSD and Green Crack! These ladies were thirsty! They will get an extra 1/2 round of feeding later this week to satisfy their hunger. LSD smells so fruity and citrusy and is frosty. Hopefully they'll bulk up from here to the finish line. Green Crack is just starting to show frost, she's got lots of bud development, but still waiting for them to bulk up over the next 2-3 weeks. Thanks for stopping by growfessors 👽🌳💚

Dump de lo que fue esta semana. Seguimos ajustando con lst la estructura que quiero y empezamos a la transición a flora. Esta semana será la última de vegetativo donde trataremos de sacar clones (esquejes) de ambas. Ya que he estado mirando videos y tomando información de cómo hacerlo, creo tener una idea de cómo hacerlo sin fallas en el intento. La próxima semana nos veremos realizando estos esquejes y veremos el avance de esta última semana. Recuerden que todo lo estoy haciendo de forma empírica y sin conocimiento previo. Todo ha sido con apoyo a videos de otros growers e información de distintas páginas. Gracias por estar aquí y compartir conmigo esta primera experiencia!

Week 9: Day 57-60: So... I'm in love with these White Cracks! #1's Main cola coupled with that PHAT ass double bud has got my wouth watering! I was worried it would be a bit too early on day 73 for #2 and #3 but they seem to be catching up qickly and are really only a few days behind #1. I can throw everything at #2 in terms of nutes and she just eats it up, what a surprise pheno after the VERY bushy and compact structure of her first 3.5 weeks. Buds are very dense on all 3 plants and SUPER frosty! They enjoy an upped dose of Calmg on day 60! Day 61-63: They are starting to show their fall colors ever so slightly, and the temperatures are going to be 2C cooler from here on out, so hoping for a little extra color 😉 Gave em all a nice final feed of bloom nutes on Day 63. #1 has about 85-95% white pistils and #2 and #3 have about 45-55% orange pistils. #1 is about 70% milky with a 5% amber and #2 and #3 are about 50-60% milky and a few amber here and there. Looking forward to these last 10 day! will be giving them PH'd water with regulator until harvest in 10 days. I only have time on Day 73-74 to harvest which I don't mind. I'm hoping this will create a varience in the type of effect every plant has to offer! Oh and these White Crack overpower the 4AM in terms of smell by quite a large amount. I can't smell the 4AM in the tent with these 😂 EDIT: Oh and just wanted to say thank you for all the help you all have given me so far! Oh and shout out to FastBuds, which sent me a message last week saying they were interested in me growing their genetics! They're sending me some free seeds for my next grow! How awesome is that!

i was surprised that she was done on 2/15/25 spidermites had completely taken over one bud so i decided to check trichomes and she seemed ready.

Still looking pretty good so far. After harvesting Girl Scout Cookies Auto, Yuhbary Auto is sharing a light with my two other, much younger plants. The light is a lot closer to Yuhbary Auto than before, which leads to discoloration of some fan leaves, but as far as I understand it, that's to be expected due to suddenly increased photosynthesis. A lot more Trichomes are getting milky, but so far, no amber ones in sight. UPDATE: That was that - Yuhbary Auto suddenly developed amber trichomes and the lower fan leaves started to turn yellow. A lovely grow, a lovely plant and a very nice outlook on what's to come in her next phase.

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! 🌱💪😂

SLH#1 is more Sativa like, thinner leaves, bigger internodal space, smaller buds and looks like its going to take a little longer to finish flowering. SLH#2 is more Indica like, large leaves, more bushy, compact, bigger buds. They've been vegged for 3 months from seed, then clones were taken, 2 clones selected to become mother-plants (kept outside the fridge, in another cabinet), and 4 clones were sent to flower. They are in 7L containers, except for one plant (#2) that's in a 3L container. Vegged for 2 weeks after the transplant and then set lights to 12/12

09-09-2025 Yesterday evening I noticed some bright yellow spots on the leaves of my White Widow. I didn’t know what it was. Today I saw that the spots turned brown. I tried to wipe it off, but I couldn’t. I think this is downy mildew. I moved the plant to the garage. The garage is quite dry and has a better humidity level than the greenhouse. I hope this will not spread. I don’t know what to do about it…

Hallo und herzlich Willkommen zu einem etwas anderen Gropwbericht. Die Blueberry Zkittlez Automatic von Sensi Seeds (der Strain heißt jetzt Blueberry Candiez Automatic) hatte ich letztes Jahr bereits angebaut und war vom Geschmack total begeistert. Deshalb baue ich den jetzt wieder an und dazu die Blueberry Automatic von Zamnesia Seeds, die schon einige Zeit in meiner Samenbank liegt. Mal sehen, wie sich die Pflanzen unterscheiden. Die URL der Blueberry Automatic von Zamnesia Seeds: https://www.zamnesia.com/de/3323-zamnesia-seeds-blueberry-automatic-feminisiert.html Die URL der Blueberry Zkittlez Automatic von Sensi Seeds: https://sensiseeds.com/de/research/blueberry-candiez-automatic Beide Strains erhalten die gleichen Bedingungen. Beide stehen in einem 9 Liter doppellagigen Stofftopf von ROOTIES (ChillWelten war der Vorgänger der Firma, heute heissen alle ROOTIES), beide haben die Sonnenerde Bio Hanferde und bekommen und später gibt's noch eine Mulchschicht mit Sonnenerde Bio Faser. Beide haben am Anfang eine Bioledex mit 10W im gleichen Abstand. Tag 60: Die Blueberry Automatic von Zamnesia Seeds hat wie alle anderen SF-Nematoden, Florfliegenlarven, Raubmilben Amblyseius cucumeris und californicus bekommen. Tag 62: Die Blueberry Auto hat bereits vollkommen reife Blüten, keine hellen Fäden mehr zu sehen. Dagegen sind bei der Blueberry Zkittlez die meisten Blütenfäden noch weis. Schau mal wieder rein, wenn es dir gefallen hat. Schönes Wochenende und bleibt friedlich und humorvoll. ✋😎

End of the last of veg. And still no major change in growth or maturity. They’re just stalled it seems. Side branching is terrible, internodal spacing is massive and they seem primed to stretch another 5’ with limited colas. Flipped to flower as of today because I’m simply not waiting any longer just for more stretch. Is what it is and we’ll see what they do in flower. ***grow notes: minimal change from prior weeks. Still no deficiencies.
