chimei said:I have read that Silica is a good additive when using CMH. Does anyone know where you can get Silica to use in Soil, is it something that would only be available in a hydro store?
Is it really that much of a benefit to use it?
simba seems to be the only one recommending it but who knows.. he seems to know everything about these CMH so I would say the 20$ for silica is a sound investment .. he mentioned silica blast so that may be a good place to start
