There is something uniquely frustrating about a search for a word that you know exists, but you don't know the word so you can't look it up in the dictionary.

I am not so much looking for a word so much as a phrase. And I'm not so looking for a phrase to describe something I can't explain - because I can explain it in Canadian. I just don't know it's US equivalent. There may not even be a US equivalent; maybe the reason why I can't find American articles on this subject is that it doesn't exist or hasn't been discovered and described yet.

Let me get to the point: I am asking my 2 American readers out there if they know the US equivalent to the term grow house.
