Added this to gardening and was advised to post here.
I got my greenhouse and didn’t account for the sloping away of the wall it was to go against. Meaning a small gap at the bottom becomes 4” at the top. I can’t push it into the wall as it warps the greenhouse and can’t leave the huge gap. Is there a way of deal with this?
I was thinking of maybe - some type of structure around it then fill with expanding foam then remove the structure. - some mesh then plaster it
