lean to greenhouse

Hi, I am thinking of buying a lean to greenhouse which would be attached to a stone wall which is uneven.  Does anyone have any tips for sealing the gap?   Any recommendations for polycarbonate v toughened glass?

    Can't advise on sealing the gap but I would go for toughened glass rather than polycarbonate @Sarah 31

    I have a Rhino lean-to against an old stone wall. We laid a flagstone floor to get a good even base and the gaps are filled with some expanding foam made for  doing just that job. I have had no problems with it and it's been there a good few years.

    I agree toughened glass is the best option.

    I used to have a 6x2 Halls lean-to attached to an uneven brick wall.
    The gaps between the g/house and wall were less than 10mm.
    I used the slats from an old blind that had wooden slats to fill the gaps before screwing to the wall. Anything similar to that should work.
    It was never perfect, but it doesn't really need be perfect.

    PS for small gaps you could also use a silicone sealant.
