For seedlings, a huge greenhouse volume is not necessary, which, in addition, is very problematic to warm. It will be quite sufficient to build a structure having a meter width, a four -meter length and height equal to 0.7 meters. Since I did not have fresh manure to stuff a greenhouse, I decided to do without it. I decided to build a cold nursery having wooden sides, and a double fortification frame: there are non -woven materials inside the greenhouse, and polyethylene outside.
