Ok Im getting some starter cps from a couple people on the forum (thx guys). My problem is i dont have the spare cash for distilled water yet. It just rained here last night and most of this morning. I collected about 3 gals of water from the roof run off. It didnt go though any guttering just right off the roof. The apt.'s I live in have tiled roofes paint black it looks like. So what im asking is do you guys think the water i collected will work for the cp's?
