thanks a lot guys for the pointers and suggestions. I mostly was just not sure if you planted directly in the coco fiber or if you had to leave them in pots. Don - you also gave me a few ideas I didn't think about at first.
And I don't know if I can do the egg crate thing just yet but it does look rather simple. I do have an extra pump laying around that I could use to pump the water out when it gets too full. I suppose I should do that before I do anything else otherwise I'll just have to tear it all down later. I have some 2-3 inch diameter bamboo that is dried and I was going to probably cut these down to size and have them where he can climb on them. Time to start designing the terrarium on paper! This was always so much fun with my old FBTs.
