Does anyone know where I might buy clear glass pots or something that could be used for planting that was clear glass and relatively inexpensive? I'm thinking of pyrex bowls. Not having a hole in the bottom doesn't matter. Also, what would people recommend for a small lighting system mounted to the top of a frosted window 33" wide, 40" tall with a 10" sill? its great fro a few plants but obviously needs light.
