:booya:I have four 3.5 gal air pots on my current grow that is aboy 40 days old. Ijust happened to check the bottom of the pots for some reason and sa a whole shit load of roots growing into my runoff trays.Roots are coming through every hole in the bottom insert.These pots along with added mychorazae root stimulater are outstanding at developeing a massive root system.Using these along with GO bio nutes ,my girls are doing awsome compared with my previous grows.Airpots rule!!!
