how big is your reservoir? and what type of hydroponics you do?
I need one more pump: I want to do ebb and flow with rockwool. my table is 1.1m x 1.1m. I am not sure which pump to choose because I did read I need to be under 10 minutes flooding time and also depends on how high I want to flood the tables.
What you think what size of pump do I need for that? (Its my first time hydroponics, thats why I am not really sure yet about the pump choices)
