its the flora flex self feed system with a pump that recycles back to a 13 gallon res that has two air stones that keeps water moving with hydroguard  and nutrients. its on a timer that feeds two minutes 3 times a day in coco with perlite. i have a bluelab guardian in the res to monitor ppm,ph, and water temp.

thanks! thats really impressive! i love seeing other peoples hydroponic setups! ive learned so much in the last few years! 

there always coming out with new and better ways all the time thats for sure.
