Greenhouses are sources of continuous throughout-a-year food production. They provide ideal conditions for growing plants for own or commercial use. This book is a guide that shows how to plan, organize resources and build your own greenhouse. It contains a step by step illustrated guide for building small size cold frames, small to large scale PVC greenhouses and glasshouses.

The benefits of a greenhouse are obvious and compelling: relief from winter's darkness; year-found gardening; a weather-proof space for basking and relaxing at any time of year; passive solar heating. But what about the costs? Of construction, of heating, of keeping the whole thing going? The thesis of this book will be that these costs can be minimized with very little sacrifice of the benefits by turning solely to the sun for heat, with no reliance whatsoever on fossil fuels. In it you will find a wonderful range of plants that will indeed bloom in this unlikely time of year.
