Great ideas! I plan on doing this after I get more info. I like the black tub/hardware cloth idea BUT the only thing is that my house is in a location where I don't get alot of sun through my windows. The back of my house is more or less all built against a hill, so only windows in one bedroom upstairs on that side...the other side has plenty of windows, but lots of trees so it blocks all the sunlight. Do they need alot of sunlight? Also what about the other way in a jar....does that need sunlight? Thanks!
