I am planning on making a small closet grow with a homemade aeroponics system. I was wondering how far my plants should be spaced if they have about 3 feet of vertical growth.
If you're going to allow 3ft of growth before flower, I'd say give each a 2ft radius of space. If you meant 3ft total growth including flower, I'd say 1ft radius of space. In the c13 cabinet (30"L x 24"W x 69"H) I found that 4 plants in 5gal pots allowed about 3ft vertical growth TOTAL was a tight fit... but rewarding!
