A cheap, jury-rigged apparatus than can be used to grow mushrooms involves placing a 1 or 2 inch layer of perlite on the bottom of a sealed container such as a rubbermaid container, then pouring water in the bottom to a height of half the perlite layer's height. The perlite evaporates some of the water and provides a lot of humidity in the container. I have used this to grow mushrooms and if I remember correctly it provides ~80+% humidity. Has anyone tried or considered using a similar setup for germinating seeds or possibly to use for rooting clones?
It seems to me like it could work...
