when you hear something like that or read something like that, it just makes me mad period. i'm from old school, literally, how can the sons of bitches tell anyone they can't catch rainwater, that's worse than just fucked up.
i'll get off the soapbox and ask the question concerning this thread...i live in an old house that sits three feet off the ground, my air system drains from underneath and it gives me the opportunity to catch the condensated runoff from the system. on very hot days which from end of may to about october, i can catch up to 3 gals on mild days and up to 8 gals on 100+ degree days which are plentiful.
i ran the water through one of the simple test kits that you can buy at any wallyworld or lowes and it came up with nothing. the hth kit shows no chlorine, no bromide, and no ph, i know that sounds strange but this water does not register anything, which gives it no buffering ability.
if anyone is interested in seeing i will post a pic of the water, it's so clear, it's almost blue. i catch in a large bucket and pour up in gallon jugs for use. when you pour it up, there is so much oxygen in it, you can actually see it. i already use it on my house plants and tomatoes and it's grown the largest most beautiful boston fern i've ever grown. any thoughts on using this water for cannabis?
