Aerogarden?

have you ever tried aerogarden for grass

Grass, being a low-growing foliage plant, would be excellent. Choose a variety that does not grow too tall. Swamp grasses would outgrow it fast, as would bamboo, but crab grass would thrive.

I think it might work pretty well with the shorter autoflowering strains. Mdanzig is doing a grow on icmag.
