I'm sure this has been answered but I couldn't find a definite answer. My grow box is small so I'm limited to where I can put my reservoir. I will have 5, 5 gal buckets & a 20 gal reservoir. I'm wanting to mount my reservoir roughly 2 ft under my buckets, has anyone done something similar to this an if so do you have any pics? I know my (outlet) on ea bucket will have to be at my desired water level & I would need a check valve after res before buckets incase my pump failed it would keep my buckets from gravity feeding back into my res. I'm really just wondering if anyone has done this? Thanks.
