gotta keep the roots all inside, 6oz is the volume of most yogi cups (or less) get crafy and cut a yogi cup up into a "net pot" diy style.
Yup, it will be a ghetto airpot of sorts with the roots being air pruned after they reach outside the coco liner inside the netpot.
Screw it I'll just get a yoghurt cup and do the damn thing.
