Winter Farming Question

[kalos72]

Ok so how they are fed during the trip back and for the interim in Norfolk is clear.

Ok so the unit is fed for 6 months, but once they land in NYC, during winter, they will need to wait another 3-4 months until the next crops are ready for harvest yes?

So that means I need to start growing food, during winter in NYC to feed the unit after the initial 6 month supply runs out.

I know crap all bout farming, can you feasible plant crops in January in NYC, keeping them in cold boxes with a heating element, out of the elements and expect a decent yield come March/April? Would that technique work?
