Various tools of the trade. Hybrid hydro. It is a recirculating system. Duel bubblers underneath. Pump on that timer. Timer is off for so many minutes and on for so many seconds. Right now it is off 15 minutes and on for 4 seconds. Currently feeding from the top. Once roots start peeking through I will feed from the bottom under higher pressure through misting jets but not foggers. On the wall is my light timer the bluish purple thing is a thermostat just in case my A/C fails. It is no good and needs taken down. The far back contraption is the same thing but digital on Equip1. Top feeder in action. A/C mounted through the wall and exhaust in ceiling. Room is approx 4 feet wide, 7 feet long and 8 and a half foot high. Because of the pressure the pump puts out, I ended up taking the caps off the top feeder for now. - I guess that is it for now.
