10 gallon vertical dartfrog terrarium construction

Is there a reason you prefer silicon?

That's an interesting question. I'm actually trying to get away from the expanding foam + silicone method. It takes a long time for the foam to cure and there's controversy over whether or not GE Silicone II is safe or not. The anecdotal evidence and my own experience is that yes it is safe. However, my next background is going to be clay (yep, the kitty litter method). I've already got pure sodium bentonite kitty litter for it. It's cheap and very quick. You just can't let it dry out completely or it will crack.

Those look great. The construction seems like it goes fairly quickly also.Is the ventilation screen made from a standard screen framing material or something else?

If you mean the actual mesh, that's not standard screen - it's no-see-um mesh sold by camping stores. Nothing can get through it.
