Title: 100% ChatGPT-Guided Grow – 12/12 Fast Flower Test (With Supervision) Hey growers! This grow is an experiment: I'm letting ChatGPT guide my entire grow cycle, from lighting to nutrients to environmental tweaks. It’s all based on AI suggestions. Of course, I’ll still be keeping a close eye on things — if I see something going wrong or the plants aren’t vibing with the plan, I’ll step in. But the idea is to test how far AI can take a grow under controlled conditions. Strains – All from @Sweet_Seeds (F1 Fast Version): Mental Rainbow F1 Fast Version Tropicanna Poison F1 Fast Version S.A.D. Sweet Afgani Delicious F1 Fast Version Gorilla Girl F1 Fast Version Setup: Coco in 20L @MarsHydroLED SmartPots Grow tent: @SecretJardin DR240W Lighting: 2x 720W LM301H EVO LEDs 12/12 from seed Germination: May 14th / Main grow starts May 20th Nutrients: Hy-Pro Coco A/B CalMag Pro, @BAC Silica Power, F1 Extreme Booster Irrigation: Week 1 hand watering, then Blumat pH starts at 5.8 CO₂ supplementation via natural gas system (Spider Farmer GGS) Goal: Complete a full grow cycle in 10 weeks or less, from seed to harvest. Updates will be posted in a personal yet informative style — a hybrid of stoner chill and data-driven grow logs. Let’s see what AI can do in the grow tent. Stay tuned! 🤖🌿 🌱 Weeks 1–3 (May 20 – June 9) – Seedling to Early Flower (Stretch Phase) Goals: Strong root development, firm stem structure, controlled stretch Light: 12/12, start at ~500 PPFD → ramp up to 800 PPFD (day 14–21) CO₂: 1500 ppm (only active when lights are on and temps 26°C) Temperature: 26–28°C day / 22–24°C night RH: Start at 70% → gradually lower to 60% Nutrients (EC ramp-up): Start EC: 1.0 → increase to 1.4 Plagron Cocos A+B + CalMag Pro (0.2 EC tap water) Always mix Silica Power first (0.1 ml/L) Actions: Week 2: Start light defoliation on lower leaves Week 3: Begin LST if desired pH: 5.8 throughout the veg phase 🌸 Weeks 4–5 (June 10 – June 23) – Flowering Phase 2 (Bud Set) Goals: Initiate flower formation, maintain healthy leaf mass, stimulate bloom EC: 1.5–1.7 (monitor Blumat watering rate carefully) RH: 55–60% Nutrients: Plagron Cocos A+B CalMag Pro Silica Power (0.1 ml/L – only until end of week 5) Start B.A.C. F1 Extreme Booster at half dose, watered manually twice a week Light: 900–1000 PPFD if plants can handle it 🌼 Weeks 6–7 (June 24 – July 7) – Flowering Phase 3 (Bud Building) Goals: Develop dense flower structure, maximize flowering potential EC: Up to 1.8 max RH: 45–50% Nutrients: @Plagron Cocos A+B + CalMag Pro @BAC. F1 Extreme Booster at full strength Actions: Final defoliation at beginning of week 6 Inspect leaves regularly for airflow and mold prevention 💧 Weeks 8–9 (July 8 – July 21) – Ripening Phase Goals: Maximize terpenes, trichome maturity, flush medium Week 8: EC: taper down to 1.4 Stop using booster Optional single flush with enzymes (manual watering) Week 9: Only plain tap water through Blumat (~0.2 EC) Temperature: 24–26°C Dim lights to ~600 PPFD for final 3–4 days ✂️ Week 10 (July 22 – July 28) – Harvest Trichome check: Aim for 10–20% amber with a loupe Optional: 48 hours darkness before harvest Temperature: Keep low (20–22°C) to preserve terpenes Deadline: Harvest no later than July 28 Powered by the new 2025 @SpiderFarmerLED GGS system.. Detailed setup (only SF parts mentioned here): SF GGS Grow Light Controller (1x) SF GGS AC10 Kit (1x) SF GGS 6 Inch Clip Fans (2x) SF GGS 6 Inch Inline Duct Fan (1x) SF GGS SensorPro Kit SF Ultrasonic Humidifier May 20 – CO₂ moved outside, lighting dilemma, and a warm future ahead Moved the CO₂ generator outside the tent today. Immediate win: steady 700 PPM from just the pilot light, no active burn needed. When turned off, it drops neatly to 400 PPM, matching the calibration point. Double-checked with the Dimlux CO₂ sensor—readings line up perfectly. Still no tracking info for the originally ordered lights, so out of impatience I grabbed two new 720W LM281B fixtures from Germany this afternoon. Should arrive Friday/Saturday. It's a Trade Assurance order, so in theory, I'm covered. Now the question: let the seedlings coast at 259 µmol for two more days, or hang the old lights to boost them to 500 µmol? Eight out of twelve are already above soil, and honestly, I’d rather not mess with the current vibe. Leaning toward leaving them be—low stress, happy sprouts. Best part: temps dropped to 27.9˚C inside the tent now that the CO₂ generator’s out. Room itself is 24˚C, so all in all pretty chill. Curious what’ll happen once those dual 720W monsters fire up… it’s gonna get toasty, no doubt. 24/05: Stocked up on new Plagron nutes—finally. Now I can lock back into the full 10-week feeding plan (Plagron Cocos + B.A.C.). Flushing the res tonight and going full reset. Mixing fresh soup right after, dialed in to match this schedule: Week 1: Plagron Cocos A/B: 2 ml/L B.A.C. Silica Power: 0.2 ml/L Plagron CalMag Pro: 0.5 ml/L B.A.C. F1 Extreme Booster: 0 ml/L EC: 0.9–1.0 pH: 5.8 PPFD: 500 DLI: 22 RH Day: 70% RH Night: 65% CO₂: 700 ppm
