I can’t find an answer for this anywhere online. I really want a Rhino greenhouse. Nothing fancy, just a small basic model, but it would bring me so much joy. I have an Indian sandstone patio which I want to put the greenhouse on. While it’s level the pavers have undulations. I’m not sure this would be flat enough. Rhino say their greenhouses can be set up on a soil and gravel base and my patio must surely we more stable than that. Ive been on Rhino’s Facebook page and seen lots of greenhouses set up on patios similar to mine. I’ve sent Rhino an email with a picture of my patio and I’m waiting to hear back. Does anyone with experience of Rhino greenhouses know if this would be a suitable base. Thanks.
