12/12 Fast Flower Test (With Supervision) - 100% ChatGPT-Guided Grow
Appoldro420 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

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.
Appoldro420 May 21th Grow Diary – Day 1
All seeds popped – 100% germination rate. Off to a banging start. Got the notification my new lights (2x 720W) are arriving tomorrow, so things are about to get intense.
Gave the girls a bit of extra water today. Noticed the coco cools down fast after lights off, probably drying out quicker than expected. Curious to see what the data says in the morning.
Had a bit of a nutrient mix-up – thought I was running Plagron Cocos A/B, turns out it was Hy-Pro all along. They're similar, but not quite the same. Plagron is ordered now, and Hy-Pro's almost out anyway, so timing worked out.
Tent’s starting to dial in nicely:
Temp: 26.9˚C
RH: 62.5%
VPD: 1.36
Coco temp: 26.7˚C
EC in coco: 0.7
CO2: 771 PPM
Light: PPFD 206 µmol/m²/s
The girls are happy. Tomorrow the real light show begins.

22/05: The German lights have arrived. Heat output is significant, even at just 50% power – noticeably higher than my previous 4x 240W panels at full blast. The AC immediately feels the pressure.
Light intensity is solid: 608 µmol/m²/s at 1 meter distance on 50%. The Spider Farmer GGS Controller performs flawlessly. Manual dimming is instant with no delay; when dimming through programmed light cycles (sunrise/sunset), it smoothly follows the ramp-up or ramp-down settings. Very precise control.
I moved the GGS SensorPro mount, so the sensor can now easily follow canopy height as the plants grow. Small tweak, big convenience.
Received a DHL tracking number from Germany today, no shipment details yet. Since I’ve got no other open orders, there’s a decent chance this is the Alibaba shipment. Supplier mentioned the tracking would only go live once the package reached Germany, which now seems to be the case.
23/05: Update: all seeds have cracked, but one of the Mental Rainbow F1 Fast Version girls is lagging behind — popped her head out, but no cotyledons showing yet. Just a naked stem with a stubborn helmet.
