Yaaa man, im trying to "sort of" cheap out on my first hydro grow, and those damn cycle timers are just so pricey, ANY other suggestion?

Hey cruzer, I got a quik question about your aero system, Im doing me own and whats the system with the sprinkler pump?

Are the sprinklers always on? If not whats the timing?

[EDIT] I am refering to your stealthy cabinet grow, In the flower area, Are the sprinklers always on draining back to the rez?
