Greenhouse question

[Mac]

Hi, haven't heard of "polly roll" either, so am thinking it could just be your Nan too Broadway. Think we're gonna go just with putting some paving down round the edges to attach it to and have the "bare" bit in the middle for drainage and dropping stuff onto! Need to organise collecting the GH ASAP as the one I've got at the minute is getting quite full, and considering it was snowing here this morning, I don't think I'll be putting anything outside for a while yet!
