Drainage layer for live plants?

[jclaiborne]

Ahh, so the saturated soil could cause the roots to rot if the water isn't drained. I never thought of that. Hmm... Going to have to come up with a way to remove all the soil with the inhabitants and put in a drainage later! This will be fun haha!

Yes you can get root rot, it will eventually kill off the plants, and it will STINK! What are you thinking for the drainage layer?
