Oh, sorry, my bad, its heavier then air... Anyway yes leave the cap off, and just put the bottle/s (I see much better results with 2..) in the grow room, top of bottles ABOVE the plants.

RastaKaze Reviewed by RastaKaze on . Grow log! Bubble gum... !First Grow! Okay, I got this plant under a 100w cfls (well one of those energy saving one, like an 18w thing?) These pictures are of my Nirvana Bubblelicious plant after 9 days, I am going to put it on 12-12 when it is only about 6-7 inches due to limited grow space. How much bud do you think I could get outa that, if any? Any advice on anything would be mucho respected! Cheers... Rating: 5
