I could tell you anything you want to know about it, at least what I know from experience.
Its what Im doing right now
Eggs are on day 51
I did some trials with box setups before my eggs got here. I found that since my lid didnt fit tightly, that I just needed to use Press and Seal under the lid to fix it.
I will say that I'll never use any Perlite or Vermiculite, just straight water for me from here on out.
