LOL. Cups have drain holes, they get watererd in the tub till they finish draining. And there is plastic under the carpet. I'm in an apartment so everything is ready to be broke down and moved in a matter of minutes. And I do got a fan, blows from one end to the other, that's why my dog sleeps in front of the closet Lmao. O, and remember that the ones in blue cups will be going bye bye here in a few days. Actually I should be hardening them off now. Haven't grown outdoors in years. This will be fun. Peace. O, and the green pots don't hold water. They normal round 6" pots. Water them in tub till they stop dripping too
