Any reason not to use a 30 gallon drum as a dwc res? :D I plan to lay it down sideways on a little base and use a pump and a garden hose to drain into my bathtub down the hall for res change.
(and yes i'm going to use a giant air pump and a chiller ;) )
I have a hempy grow in a dr but I didn't do very well and it was from seed and only 1 female.
This time I'm going to burn another like $600 or so and finish up the tent+scrog and dwc. I am a bit of a freak and must share with you all that this makes me horny. See you in a few weeks :eyesmoke...
