they drain and dry faster which in turn helps u pump them full of nutes more often. "more waterings" plus im not sure how they root system grows but it gets massive way faster than the plastics do. i think it has to do with the drainage and the fact that the roots grow outward and not straight down and then curl like the plastics do. once the root tip touches the edge of the fabric pot it burns off and dies from the air. its kinda like topping ur plant. u cut the top off all the other branching explodes. same concept with the roots so to speak. ill look up the exacts and post them tomorrow. ill try to post a link.
