Ok, I want to do a 36-48 site drip irrigation using rockwool. I'll be buying around 6 dutch trays that are approximately 1 meter long. I want to use 1/2 gallon stake drippers. What size pump will I need? This is driving me nuts, there has to be some sort of formula somewhere, but i'll be damned if I can find it.
