John helped me and my wife out were having twins and want to try hydro gardening here in the desert, SNWD sprinkler limitations makes it hard to do a traditional one, so we recycle our water each week in a soilless mix and it's working, until we found out the hard way you need to nutrient the water in a system like ours hum? Guess that was a f-up on my part but thanks to a visit here John helped us out and we didn't loose any plants but probably stunted their growth a little. But at least we are growing our own food in the desert heat cool
