Any of you know where to get rectangular plastic pipe/PVC? I'd like to build a NFT system but I haven't found a good source for the pipe.

Also wanting to build an aero (cloner) system but not sure how to pick the right pump. I'm sure it's based on the diameter of the pipes and the number of sprayers involved...if anyone can show me the math I'd appreciate. I'm always impressed with your projects latewood.
