I am going to have General Hydroponics three bottle set for nutrients.

For the resovoirs i am going to have for the two mothers and clones a FIVE GALLON (?) water supply on a drip system. What strength pump will i need for this?

In the flower room I am having four flowering plants on an ebb and flow system with TWENTY GALLONS (?) water supply.
What strength pump will i need?

Also how much volume must the tray they will be in be?
