Um....I don't know about where you live, but over here? Greenhouses usually work best if you take them out of the box? *just kidding*

Nice one Annie ,..when i first read the heading,.."Greenhouse In A Box",..i was thinking of that system where one places Straw in a box but i can not remember for what purpose ,..it was an old system used in a kitchen,..the mind boggles.

You still have me laughing at your comment and i will get it out of the box and assemble it when the weather improves,..i should have made up my mind and purchased it before the Autumn
