I guess i've been picturing less of a flow in the whole thing, and more of a dripping trickle lol. I've got most of what I need now from the depot, minus an aqua pump. I've been trying to stray away from ordering hydro products online, but i'm tempted to just order the pump and nutrients I would need anyway. The nearest hydro store is pretty far from me. But, I want to do it right the first time and not have to work out any major kinks later on.

How many gallons per hour would 4-6 plants use would you say? In clay pellets/netpots
