Are you planning to put peat on the great stuff and just concrete in the rocks? I thonk that is a great idea

i like the rocks. they look great!! Are you gonna grout the gs too?
I like the soft foam because carving the hard stuff sucks but worry about soaking up water!! Is that a problem you think?

I'm planning on trying some soft foam in the alien viv anyway. I can make some weird shapes with that ;-)

i really like the rock wall with the dirt wall. Looks good!!

I too am not a silicone fan. Gorilla glue all the way - although I will try titebond since people seem to be having luck with it!
