For the terrarium size, lay out some extra jar lids (or something the same size) to see how many you can fit. Make sure they are a couple inches apart from each other and the well.

I think the monkeys at the zoo should have to wear sunglasses so they can't hypnotize you.

But Buffalo Trance is absolutely right, it is one more step at which you could run into problems. When I was first starting out (some 20 years ago) we didn't have PF Tek...and casing rye grain substrates was standard method...it took me a while to get the casing mix, moisture content and initiating pinn set down. But you have to learn sometime, right. Success your first time will go a long way in building your confidence.

Which ever way you go...the best of luck to you.
