They have it at home depot, walmart, most grow shops, and every garden center everywhere... look for the active ingredient, bacillus subtilis.

Yeah fresh air flow is crucial... a fan... ANY fan... just find a fan!!!
stinkyattic Reviewed by stinkyattic on . Have I got mold?? The picture is of my White widow leaf, 3 weeks into flowering. I think the lighter brown spots are mold and the darker littler spots are from a deficiency, I also think it might have a mild nitro def also. I cut a few leaves off the bottom-Middle that had these spots on them, but whatever it is is still spreading slowly. Could it be my humidity levels? It gets kind of cold at night and there is water in the air because of the moist dirt. Any suggestions appreciated, thanks. Rating: 5
