I've been having good luck with it, Atwoods carries this, but probably the same everywhere. I buried it down 4"-6", made about a 16" loop around all my tomato and pepper plants. Keeps everything damp down where the roots are and there's very little water loss on the surface. Keeps the leaves from getting wet as well..I got two of the 100' that Walmart sells. They put out a little more water at the first of the hose vs toward the end. They weren't very expensive.
I tried hooking them together, but the pressure loss at the 150' mark was down to zero so I ended up using one of those cheap splitters to feed them separately.
I'm already just about out of tomato cage...
