So they area in the attic. And temperature at night can dip to 8C° with a daily high of 20-24°. RH is 50%. I have already ordered a heating mat that should do the work. But what have I done to them already? They are in the ground for 6days now.
For 6 days they are doing fine. Maybe a day or 2 behind where I would probably expect them to be at but the low temps of 8c at night might have caused that.
