NH - It's not a silly Q. It's one I've considered this year when planning what to grow, to extend the growing season and make the most of the space available.
I've tried Christmas spuds, these are best grown in bags and planted July/.August time using 1st or 2nd early seed spuds. You lengthen their growing period by bringing them under cover when the nights start to draw in and frost is threatened. Inevitably their foilage dies back end of October/ beginning of November depending when planted, but stored in a shed or GH you can dig them up in December.I finished eating home grown spuds in February and started in July last year.
Some winter veg needs a long growing season, leeks and brussels spring to mind but there must be others but these don't need a grow house.
I'm planning leeks and turnip this year to pick over winter. Turnip will be a late sowing as I've kohl growing where they are planned.
I've yet to be convinced things grow in unheated GH and plastic grow houses over winter.
Did you have anything in mind to grow NH.
