My water is OK for feeding plants that are already well-rooted, but boy it is some metallic and salty-ass well water. I couldn't get nary a friggin' taproot for cloning about 10 days, then I changed the water in the bucket cloner to store-bought spring water and a few days later 5 of 8 were ready to put in soil. Three died. I was saddened! I now keep spring water around for the babies and clones, but use my harsh well water(that's supposedly an artesian spring) for mixing nutes and general watering purposes. My plants look fine as all get-out(I think).
Regarding the OP, HTG Supply on Rand Rd in Portland is the place to go(htgsupply.com) if you are buying new. I've dealt with others, but feel they are the straightest to deal with and feel 'less-raped' than other places. You've got to realize that you are getting screwed anyway(unless you can find a deal on craigslist for under $200-I'm freakin' jealous!), so the less the screwing, the better it feels, in these circumstances. IMO
