I'm planning to build an new aquaponics set-up. I live in the Netherlands which has a moderate maritime climate, with cool summers and mild winters. I will be growing lettuce, paprika, tomatoes, basil etc. It will be under protection of plastic in the spring. It will be open in summertime. I am irrigating with an ebb and flow system. Should I insulate it so temperature would not vary to much during day/night? Is it important to keep root temperature stable? What temperature range should is be? Can I use the ebb/flow as a cooling method?
