water pump size for 6.5 gallon buckets?

[hideous]

title sums it up Im going to make a few aeroponi buckets and they will be 6.5 gallon same dimensions as a 5 gallon bucket but square so it adds 1.5 gallons of water.

I have read and read and read and people seem to vary widely on the sizee of pump needed.

Im looking at the eco line of pumps I have some good info on them here...

Im wondering how importand the amount of water is vs the force of the water?

I read that those small sprayers only put out around 1 to 10 gph, in fact most like the ones i see used are like 1 to 3 gph.

So should i be looking for pumps with lower water flow and higher pressure?

for example is the eco 132 better then the eco 185, less watts and more head pressure?

I've got an amazon system which feeds 4 sprayers from a microjet1000 (1000lph) pump which works A ok. looks like the system uses hozelock sprayers (0-40lph) which are adjustible up and and down, so im guessing a 500lph pump with a couple of sprayers would be fine. BTW the first link you posed comes back with bad request for me.

I'm probably way to late, but if your in Europe and need any kinds of pumps and sprayers to make a hydro system for nothing. The products they carry are the cheapest I've seen. I'd kill to make an order but they don't ship to the states.
