Hey guys, just got this beautiful 4 ft. hexagon as a birthday present from Jason Perillo at Protean Terrarium Designs. Any recommendations for construction? I'm considering constructing a tree buttress from foam and having that as the centerpiece. I will hollow the tree buttress out and fill it with soil and have a ficus sprouting out the top. As for species i'm considering either P. Klemmeri or L. williamsi. I'd like to have a tree frog species mixed but that depends on how the terrarium turns out. The first foot will be for drainage/soil.
