that is basically what I did...each tray has a troth on both sides. I put drippers at the far end away from the drains and pump solution to each tray that way...not each plant, just a dripstream.

These clones are all rooted and I am planning on finishing them right where they are at. I just meant that I wasn't growing from seed this way...I clone in my aero-sprinkler unit, then I transplanted 11 rooted clones into these trays. Isn't that what you are suggesting? thanks lw
