it will be a hydro..with a twist...I will post pics of set up as I get things ready...just need to set up an timer...etc..I will have a res. but cup will not be sitting in it the water...it will be auto feed via pump..hence the reason for drain holes so it can fall into storage res. ..make sense?..all roots will be contained, except a stray one lucky enough to find a pin hole....if it dont air prune..I will just rub it off
