But grow lights may be GREAT for herbs and vegatables......

But the "chi" you are looking from the whaetgrass does not come on very much if at all growing with artificial light.

Grow in just about anythingYOU want to......But NEVER use Manure....tables scraps....egg shells etc. Ecoli and Salmonella potentail are increased.....Topical mold is not hazerdous.
