Hydro noob here, building a 4 site RDWC: 4x 5 gallon buckets, with a 5 gallon res, so probably 15-20 gallons when full (going into a 4x4 tent/res outside tent). I live in a hot climate so I’m thinking instead of hot noisy air pumps, I’ll go waterfall, with an inline pump pulling water from the res and connecting to a spout-like attachment at the top of the side of each of the bucket sites. So my questions are, what size (GPH) inline water pump will I need to circulate enough water for the waterfall? Will a waterfall in each bucket provide enough dissolved oxygen for my ladies all the way through veg/flower? Will I still need a small air pump in the res to keep the solution from settling? Any advice is appreciated!!!!
