With a greenhouse in the garden, it is possible to grow a lot of vegetables and fruits in a small area, as the growing season is much longer compared to open fields. Passive solar earth greenhouses are a good alternative to the standard transparent greenhouse, where the internal temperatures in summer are usually too high for the plants, and in the cold season, they are too low. This book provides detailed and practical guidance on how to build a passive solar earth greenhouse for the home garden, where it is possible to harvest (almost) year-round vegetables, salads, and fruits without additional heating. Although the numerous examples of self-built greenhouses may seem quite different at first glance, they all share certain structural features. This is what this book is about. The good news: This also applies to transparent greenhouses.
