we were drinkin one night and just shootin the moon and we actually thought of a bunch of differnt ways to grow in a bathroom...our idea was with a garden tube or what not but a stand up would be just the same..well if u did hydro..your all set..u have the water and then the drain...in the same room..pretty sick..pluss u have an out vent if u have a power vented shower..iether use that or boost it with a inline and a carbon filter,
