I'm not at all experienced with keeping a terrarium. I got one as a gift for Christmas. It's in a one gallon jug, very narrow opening. It got the white mold discussed here, and I instinctively took the cap off for about s week. Now everything in it has died. The soil, sand, gravel, etc layers are the more attractive part, so I don't really want to dump it all out. The mold itself seems to be almost gone, so I'm considering trying to start new plants and see what happens. But how do you get into it to remove the old and plant new? The opening is only 1.25 inches and the top of the soil is almost 8 inches down!
