Alot of people say dollar store for your fake leaves but i suggest Walmart. my dollar store has 15 dollar plants compared to walmart with their 3 dollar plants.
and why stop with just one or 2 hides? give him 4 or even 5 clutter it up! lol
also if your having a problem with the humidity down the road with such a big enclosure Take a glad ware seal-able container that your snake can fit in very roomy,cut a hole in the top melt the cut sides with a lighter to smooth it out to prevent cuts, fill with moss and wet down generously, works wonders!
