Here’s one to try for short season before or after main crops:
Little Giant Sweet Corn - used to be sold by Bountiful Gardens. 55 days to maturity. Short stalks. Link below may be the same:

I personally like the Country Gentleman white corn. I also am thinking about the Stowells Evergreen which they used to pull up by the roots and hang upside down to have “fresh” corn well into the winter. Both are available @ Bakers Creek. However, I’m not sure about the height of these.
Maybe I should clarify. I meant what’s the smallest greenhouse you would want?
I have several varieties of corn I’m trying to preserve :)
