Week 7 – Day 51 (Flower Day 21) 🔄 Recap A calm and steady week. Mostly just watering, observing, and occasionally removing a leaf or two 🍃 The stretch seems to be slowing down – space is getting tight, but still manageable 😅 pH & Soil Compatibility One thing I’m noticing more and more: The drain pH stays low and doesn’t really increase, even with feed water at ~6.6. After some digging, it’s likely due to the combo of BioBizz Light Mix and Advanced Nutrients. BioBizz relies on microbes for pH buffering, unlike soils like Plagron Growmix or Canna Terra, which use dolomite lime. I’m also using Bud Candy, which seems to push the pH even lower by feeding the microbes. 💡 Conclusion: If you’re using Advanced Nutrients, soils with lime buffering might be a better match. 🌿 Plant Status – White Widow 📏 Height: 97 cm – still stretching strongly 💧 Drain pH: 5.7, but she doesn’t seem bothered by it ⚗️ Feeding at 85% of the Advanced Nutrients Masterline ✅ She’s doing great – no issues at all, healthy and vigorous!

Start of week 7. Stopped feeding big bud, started feeding overdrive. Plants are extremely sticky to the touch and they smell very citrusy. Two weeks until flushing.

Taste like sour and grapes 10/10 , Big solid buds :)

Some plants are showing sex always an exciting time right also did a topping and started some lst gonna keep them in 1 gallon pots awhile longer then final pots after I know how many females I’m working with

Still only giving them water at ph6. 5 The soil I started them in is a full strength soil. House and garden bat special 🦇💪👍 Some people say I shouldn't plant seeds direct into full strength soil, I've been doing it for 20 years and never had any issues . Each to there own I say 👍

I made a concoction of living soil using ingredients I could find of subcools formula. Theoretically all i need to add is ph balanced water. And a tea once I decide to flower. I'm waiting for some gadgets[ph and moisture meters]to come in before doing any extensive watering.

We will see how the process of it ... I just realized from comments that this brand buys seeds wholesale and sells them as seeds of this brand ... they are shit ... it should be from a seed bank. .. Hopefully everything goes well...

Welcome I was wrong to defoliate in the fifth week, the same week I sent them to bloom Finally begin to bloom, after a week at 12/12 where unfortunately they have vegetated again 😅

Looking nice;))))

These girls been growing up Amazingly. They are now in flush mold until harvest

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! 🌱💪😂 1/18 11:58AM. BRAM STOKERS TRAILER PARK DRACULA........I SHOULD BE WORKING ON THE PLANTS BUT THIS IS REALLY GOOD. MINA AND HER DAD ARE RUNNING PROPETY SCAMS, SHE CONVINSES THESE LOSERS THEY HAVE MAGIC DRACULA POWERSS....AND WE STEAL THEIR TRAILLER. REINFEILD RANDY , JULIANFIGURES IT OUT AND BLACKMAILS BOTH OF THEM. AND MUSICAL GUEST KISS!! A GREAT HALLOWEEN EPISONDE.... OH I FORGOT I AM SUPOSSSED TO BE GRWOING PIT.

01/19/2022 Stretch is starting, watering till 5-10% Runoff. I will be giving some molasses 2 tbls to 2 gallons water to feed the microbial life in my soil. This should help nutrient uptake from roots, feeding her flowers with microbial chelated nutrients. Changing to 12-12 tomorrow at lights on. Which will continue through flowering week 8, week 9- harvest will go to 11-13 for the fantastic finish! Getting rid of the dark green male he is not adjusting to drought (lack of water) as well as lighter green male. Lighter green can go twice as long without water with no sign at wilting

13 ounces wet weight! Which is amazing for one auto. She grew like an absolute champ and bud sites were plentiful and filled in beautiful. Nice dense nugs and extremely pugent diesel smell which is great for the aply named Sour Diesel strain. Sticky and stinky, looking forward to the dry bud, should be around 3.5 ounces all said and done. Best autoflower to date.

😍

Everything went ok this week. They seem to still be drinking ok but not as much. The flowers are hard dense. I also notice the smell isn't as strong a week ago. This week I downgraded the tea to just molasses and my diy compost.

Day 62, watering with pure water + enzymes until harvest. I found a great pheno with a mandarin slushie aroma, while the others smell like gas with light citrus notes
