put drain holes in the bottom of the rubber made,and put the rubber maid on some bricks bc it will allow for the water to drain and it would be strong enough to hold the container up. the way im thinking this is that you could posibly get a few pounds if your lucky. i would intertweave the branches inbetween the screen. just thouroughly clean the screen with rubbin alcohol bc the stems will grow around the screen and form a rock hard conection. blah blah blah,this way you wont have to worry about any conatminants being forced into the plant. get like 3 screens,about 1 inch above the other,but only put one screen on at a time,fill the screens out with fresh veg this will alow for max exposure to light,blah blah blah,get creative with interweiving
