You could research commercial greenhouse design to see how the pros do it. I think many use retractable shades, hid lights on movers, and gas burning/co2 creating heaters. I had to stop researching that kind of stuff cause it makes me want to cry that I can't have.
Alternatively you could search for an operating greenhouse at a similar latitude and call and ask for a tour.
There was a pretty well publicized roof top farm in either Cleveland or Milwaukee(forget which) that had an aquaponics system going. I will see if I can find a link. I am pretty sure they give tours too.
