Film-plastique-bache-de-serre-bache-camion.43664682-98159082.jpg Plastic cover: For the cover, we use transparent, U.V. resistant, 200 microns plastic film. It's not the most beautiful solution but it's the cheapest one. Alternative solutions (glass, transparent polycarbonate, or polymethyl methacrylate (PMMA, or Plexiglass)) are much more expensive.
Velcro-horizontal.jpg Fasteners: So far, we've used hook and loop fasteners (velcro) to fix the greenhouse cover. Alternative options are snap fasteners and eyelets (Fr.: oeillet metal) but we haven't tried them, yet.
