No plastic for me Calin.
But all of my plants have to be tough, no pampering. I do have a few that I bring indoors for the winter, but most live year round in whatever nature throws at them.
I guess that is why l love the hardy succulents, alpine, and native plants.
the closest I come to having a green house is when I do winter sowing.
