for those of you who use rainwater to water your CPs, how do you collect it? i just collected a ton of rainwater from the downspout off my roof, but when i posted about it on another forum i was told that it probably wasn't good to use because of stuff leaching out of the shingles. the water was a kind of murky brown. does anyone here use rainwater from the roof? do you filter it or anything before using it? if you collect rainwater some other way, how do you do it?
thanks!
thanks!
