Thanks for all the feedback guys! There was so many posts it'll be hard to respond to all of you. But some of the questions I noticed I will answer.
My idea in this is to produce the best results for my snakes, and for the planet. I just think of how many plastic bags I fill with dirty bedding[lots of animals], how many plastic bags I buy my bedding in and can't find a second use for. Animal Life newspapers are great free resource I shred in a paper shredder and I use with the rats. Some websites have mentioned the ink is harmful for snakes, even soy inks. This is surprising to me, because rats are very sensitive but do fine with the newspaper. Any body know anything about this ink-based rumor?
Here's questions answered:
Why not compost aspen? You're not really supposed to compost wood because it just takes longer to break down. I guess some people here have tried composting it, and noticed it does take longer. To make a good compost, you need 3-4 things. Rotting things [preferably non-meat/dairy] and/or manure, and leaves and grass which are essential ingredients in the breakdown process. I was thinking meadow grass would be great to use for both the snakes and my compost which requires green grass. Plus won't the snake be pleased to be in a more natural environment? I know a lot of people seem to think the snakes don't care if they hide in a purchased molded plastic hide, or a cheap chinese food take out container, but I think it's more pleasing for both my eye and the snake's comfort to have a good place to hide.
Someone mentioned won't you worry about pesticides and bugs/parasites/diseases, I am actually more worried about the aspen I get from wal mart, as the only thing I can do to cure it is to put in the fridge, and most websites say 1 month frozen which is quite a bit of time and space in my tiny freezer

It keeps the snake food warm though

All of my outdoor items I cure in the oven before sharing them with my animals. The meadowgrass would be risky to cure but if I buy it from a local farm, find one who doesn't use chemicals i.e. "organic" I believe a lot of farmers cure the hay themselves. So it is safe for animal consumption.
Sorry for being so bizarre about my snakes and such, I am just a nature nut with the vision of creating a natural terrarium for my snake buddies [and rat friends too!]. I want it to look like you just stepped into a forest and there's a snake chilling on that log over there, lol. I keep all sorts of treasures I find outside on hikes like twisted brances, bark hides from fallen tree trunks, and willow branches from 4 big Willow Trees right around the corner from where I live. So the animals climb some different textures instead of just plastic or metal, which I am sure must get boring from time to time.
