I have actually tryed that once. . . i used a speaker box ass a "grow room" i guess u can say.i hung the lava lamp upside down from the top of the box. . .it did the trick for a little bit but after about a week or two my plants would jus slump over and die, i thought it would work myself, i still did just intill i read this, i figured having my plant closed into a speaker box wasent allowing Co2 inside and thats what killed it, but what do i know :wtf:
