Does anyone use the Raindrip irrigation system? I was given 3 different kits free and set mine up w/.5 gph drippers. Looks like it works well. Should have done this before summer, lol. So far, it doesn't seem like any problems. I think I'll be able to reduce my planting(counting on higher yields.) Can anyone tell me what to expect? I have a friend who uses pvc w/ manual valves and drip tape. When I have to buy, I may go that route.
