At the begining the substrat was too wet (green alage!) so I opend the seeling box and the humidity dropt from 70% to 50% instantly. I also startet the fan and the air flow and did the light on 80% (15cm!) with that (about day 9/10 after seeding Day 4/5 after sprout). I also stoped watering for 3-4 days so there will be no mold. On da 7 after sprout I did the light on 100% (30cm) and watered every 400ml substrat with 100ml water (withou pH correction) with Green House BioEnhancer 1g/l. Because it was quite cold (18-22°C) I installed a warming plate (18/6) under the pots.
