modular hydroponics tower

A modular hydroponics tower. 1/2" supply, 1" drain, 1/4" drip lines to each plant with 2gph emitter on the end for pressure regulation. May need a bigger pump. Currently using 450-650gph. Use Sand wetting for sapling starters (pizza pan with PH neutral sand, and an upside water bottle with nutrient solution(vacuum pressure to keep the bottle full) to keep the sand wet). Pump needs to run 24/7.
