someone i know did this in a plastic drum and he used a pexi glass to cover the top of the drum with holes in it, just be sure to drill a good drainage source into the bottem of the drums:jointsmile: you might want to even grow the plant into a pot and transplant it into the drum.. my bro is a fan of overwatering but it seems to work wonders because his plant looked amazing. good luck and dont get nailed:thumbsup:
