Will do. In four days I can turn on the auto pot and hope for explosive growth. The yellowing has gone away. One plant showing new growth.I would let them go for atleast a day or two. Let the coco dry out until the top layer gets dry Sometimes you gotta stick your fingers in and get dirty to dee how wet your coco is. I would not use a dome personally because you can have them dampen off. 70 RH is plenty enough i would not risk it.
Also how big are your pots?
