D2 s. AI plan. Only Mars Hydro ventilation 24/0 (2/3).
D3 24/0 to 20/4 according to first plan.
1x water (60 ml)
AI PAR Estimate:
Current: 80W @ 25cm = ~450–600 µmol/m²/s (center), ~350–450 µmol/m²/s (edges).
Optimum: 200–400 µmol/m²/s for seedlings.
Max Absorption: ~20 mol/day with 24h, ~16 mol/day with 20/4 (seedlings need ~12–15 mol/day).
Comment: 24h provides slight surplus but not essential. 20/4 is more efficient and reduces stress.
D6 1x water
D7 Complete analysis (overview, then every single plant):
10.01.2025 (D14 / W01D7): Plants stable, 80 W light at ~25 cm, no stress signs. Humidity (85%) and temperature (~24°C) optimal. Light increase to 120 W planned for 11.01.2025. No actions needed.
Plant Summary – 10.01.2025 (W01D7 / D14)
Apricot: Stable growth, no issues, good leaf development; Grade: A
Mix#2: Symmetrical, healthy leaves, great condition; Grade: A- (Slightly slower growth compared to Apricot)
Purple Lemonade: Good leaf structure, no issues; Grade: B+ (Growth slightly behind)
Mix#1: Robust, symmetrical, slightly more compact; Grade: B (Could show more vigor)
California Snow: Healthy, smaller than others; Grade: B (Slightly behind in height)
Order (Best to Worst): Apricot, Mix#2, Purple Lemonade, Mix#1, California Snow
Comment: The grading is more or less forced and of course has probably not much meaning ;-)
I am afraid the stupid machine will be too polite to critisize anything if I do something wrong or the plants look poor😂
