My home made vertical hydropoic system
I had an idea to make a vertical system after seeing much more similar expensive systems. It's aeroponic and the PH swings way high overnight. I know I read about why PH swings like this in a magazine the past year but can't remember what the cause was. I think it was in Cannatalk Summer issue (thrown out now)?
Anyway it's 5 feet tall and grows 12 heads of lettuce within 1 square foot. I'm using Maxigrow at 350 PPM.
I used Maxigrow the past 5 years in DWC and had no trouble with lettuce for PH. Plants look fine but trying to make things perfect. Any idaes?
