There are numerous options available to the allotment gardener, to bring forward the harvest of the individual vegetables.
Except for the fixed installations, such as small greenhouses and cold frames, the range extends from transportable foil tents and hiking boxes to temporary covering with perforated foil and plant protection hoods. Many of these “culture aids” can be made by yourself with a little manual skill. In addition, the specialist trade offers numerous types of small greenhouses and foil tents, which are recommended without exception. When building your own small greenhouse, you should not choose the dimensions too small, because the smaller the enclosed airspace, the greater the temperature fluctuations. Under a greenhouse width of 2 m one should therefore not go. The available material is not sufficient for such dimensions, then it makes more sense, to be satisfied with a cold frame or foil tent or to purchase a ready-made type house.
