3 gallons per plant. I'm sure the smallest pumps will work. I have run a 120 gph on 6 drip plants, would do 8 but up to 360 gph will work. Ebb and flow the same. Your not moving water under high pressure so no need for a big pump.

Pumps how big of a water pump would you need for like 4 plats on an ebb and flow system....and how many gallons should the resivoir be? also how big of a pump would you need for about 8 plants on a drip irrigation and how many gallons should the resivoir be?
