Oh don't get me wrong, I'm still growing hydro and I don't hate the waterfarms, quite the contrary. I've had some sick results, I have picks of plants taller than me and 1 1/2" 2" trunks. Some say I may have set records! I've simply modified to make them work. I totally agree about the tinkering. I love the challenge and I've figured out a way to make them work. Circulation is the key and I don't think that way is the way to make it circulate. I bought a sick airpump that can run 12 lines and it was not moving it. I am working on a system that I hope will work and if I do I'll be sure to post it!
