Very Nice! I was thinking of using the PVC
when I build mine again but I was going to make an entire sealed square out of it. Then I can control the humidity and add short pieces of the PVC
coming out the sides for a little circulation.
I think you idea of using pots is a good one. Also, if you don't mind a little update, what is the soil you finally decided to use? I remember you saying Turface MVP but it kinda looks like regular potting soil.
