Water

Just curious about what kind of water people are giving their plants and how...
do you use tap water/ro system/gallon jugs from kmart? How often do you flush?

Here's my deal: A couple of months ago I started using straight tap water because I was tired of buying RO/distilled water and my plants just started flowering and were extremely thirsty. Within a week they had pretty much stopped growing and were looking decidedly unhealthy, so I flushed and things started looking much better after that -very quickly actually, like within a day or two. After reading up a bit and testing my runoff and tap water, I realized that my problem was the high pH of my tap water (btw 8 and 9 when it comes out the faucet) and that I wasn't letting enough water run out leaving my roots sitting in a salty muck of horridness at the bottom of the pots....

My remedy was to get 2 5-gallon buckets from home depot and an 20$ aquarium pump from the pet store along with an airstone and tubing. I fill the buckets, put in the airstone for about 24 hours before watering and by then the pH is around 7. The difference has really been dramatic compared to the tap water and the plants love it as much if not more than the RO water!

I use tap water but let it sit out for atleast 24 hours to make it distilled.

I use tap water also, but boil it heavily for about 15 minutes, then let it sit open for about a day. Tap is healthy for us, but not for our babies. Once in a while I'll buy a gallon of purified, not distilled, water and use that.

I use nothing but distilled water.. It pretty much comes 0 ppm and right around ~6.5pH , Lets me feed my babies how I like! Haven't had any problems with it yet.

I use rain water unless that is not availb., then the tap water. My tap water is between 9-10 PH though, so PH down is a must. Plants really love rainwater. Kinda sucked for my last grow though...been in a drought around here up until just recently, but now I'm collecting all the rainwater I can. LOL - containers everywhere.
