No the light would go through the glass and kill ur roots

LOL im a jackass my bad.. i was looking at the wrong thing.. umm i'd still have to say no, because u want your roots to grow and stretch for water.

i have seen house plants grow with those marbles, but never cannabis.

do a real hydro system and use hydroton.
