Some of my seedlings are already growing, should I keep the cover on top of the tray until they all do, or leave it off already?
One of the seedlings has yellow tips, is this because it stayed too wet? Or is there a different reason?
I have a fan arriving today, should I set that up right away?
Thank you so much! It's my first year growing more seriously / specific varieties, and I appreciate all the advice and knowledge on this sub so much.
