Cultivation log — 2026-03-04. Mean canopy temperature: 19.1 °C. Relative humidity: 55.1 %. Grower observations: All 4 seedlings are now fully emerged and looking strong — very uniform progress over the last 24 hours.
2 plants are fully out with cotyledons wide open and first true leaves just starting to show (nice green color, no stretching).
The other 2 are right behind: cotyledons completely lifted, seed shells off or almost off, tiny true leaves peeking.
No damping-off, no shell stick issues, no yellowing — stems are short/stocky, roots seem to be taking hold quickly in the coco/clay mix.
Current setup notes:
Light: Mars Hydro TSW2000 at ~70 cm, dimmed to ~40% (gentle for early seedlings, prevents burn while giving enough PPFD for growth)
Environment: Temp 22–23 °C, Humidity 72–75% (steady on dashboard), CO2 ~1500 ppm sealed
Medium: 70% coco / 10% perlite / 20% clay balls in 25 L Aut

Medium: 70% coco / 10% perlite / 20% clay balls in 25 L Autopots
AirDomes: gentle constant bubbles
First feed: light CalMag + fresh Orca mycorrhizae in top water
Extras: classical music 1h AM + 1h PM, weak electroculture current running
Next few days: keep humidity high (70–80%), light at 40–50%, monitor for true leaf expansion. If all stay healthy, plan to ramp light to 60% by end of week 1.
These autos are off to a fantastic start — super uniform and vigorous! 🌱📸
