Hi, I’ve been growing on and off for about 20 years. The last 2 years I have gotten serious and have a low pressure aero setup. I know its not a ‘true’ aero setup but works well none the less. I have a couple of laundry tubs that houses plants, and another tub for a reservoir. The res pumps nutes into the 2 tub via sprayers and they drain back into res. I only grow a few plants at a time (enough for 2 peoples useage).
I must be lucky because Ive only ran into problems a couple of times and I was to blame each time.
salt buildup- i was always adding nute solution to top up. Later realized that i should only top up with ph’d h2o (now I can fully understand what my girls are doing based on ppm)
waited too long to flower and had issues with the lights too close because I ran out of height. Had an awesome yield but a couple colas foxtailed on me slightly.
turned off system to make adjustments and forgot to turn back on! Haha…the plants literally had no water pumped for over 12 hrs and I still managed to save them! Oh boy
Looking forward to learning and sharing.
