Perfect start.
The micro growing space under the stairs is appropriate to begin the vegetative cycle in 3L pots: more easy to control temperature and humidity.
Winter is coming, I added a ceramic horticultural heater 45W (+ heat mat 50W) to maintain 21/22 degrees during cycle day.
Feeding with Root Juice and Tarantula 2 times. Sprinkle soil with dried horn and blood for low nitrogen diffusion.
vaporization with rain water.
It’s another story to grow photo periodic plants; it’s not a race against the time like growing auto flowering plants. May be 7 weeks vegetation for this session.
Just afraid about the electricity cut during the winter. The temporaries blackout will be announced the day before….I bought a rechargeable (USB/solar) COB light to have a few hours autonomy.
