Do you guys do foliage spray with indoor or do u guys just water the soil? When would a good time to add foliage spray? If I'm using cfl , could the spray burn the leaves with the light like with the sun outdoor?
most any mild soap, a drop is all. It breaks the surface tension, slows evaporation, makes the most of your foliar feeding. I have some dr bronners in the grow room so I use that. It also suffocates air breathing insects
google "foliar feeding wetting agent" maybe for more sci info.
