Listen to Zandor man. My drip system had 3 inch pots and would grow 4 feet plant but the root were really tight. Look up loc nar1958 red hair ladies and papya grows. But really go witth big net pots and hydrotron, just don't let the drip, drip right on the rockwool make it over to the side alittlle. Root balls don't like to be wet all the time.
