Hey man if you keep em under the MH put the clone dome over them and prop it open so there is passive ventilation. BUT, put 1 or 2 cups of water in the clone dome with em, this will keep the humidity up.

harris7 Reviewed by harris7 on . seedlings issues hello, I have recently germinated and planted my seedlings. They were doing ok, but when I changed from my shitbox 150W CFLS to the 400W Metal Halide, some of them shrivled and died. The others look ok but I'm affraid their roots may have been damaged by the heat or something. Also, they're in a clone dome right now, should I remove it? Thanks.:stoned: Rating: 5
