Solar Rooms. Search The Renewable Energy site for Do-It-Yourselfers Without ventilation or thermal mass, the temperatures of spaces having large areas of south-facing windows will fluctuate widely.
Temperatures of conventional non-solar greenhouses, for example, can rise to over 100° on sunny winter days and then drop to below freezing at night. If a sun heated room is permitted to have wider-than-normal temperature fluctuation, then the costs of thermal mass (to store heat) and movable insulation (to reduce heat loss) are avoided. The excess warmth from such a "solar room" can heat the house immediately, or if mass is added, heat can be stored for later use after the sun sets.
Greenhouses are the most common solar rooms. A solar greenhouse is designed both to maximize solar gain and to minimize heat loss. For maximum sunshine, and for minimum heat loss at night, movable insulation is used in combination with double glazing. Which Direction? Heat Storage Costs Large Solar Rooms.

By Lynn Byczynski Among the many season extension structures in use on vegetable farms today, one of the least expensive is the caterpillar tunnel. Caterpillars — so named because of their segmented appearance — are constructed of pvc pipe, rebar, and rope.
Caterpillars are easy to build and move. Caterpillars are used for many crops and many purposes. This article will focus on growing summer crops, including cucumbers, tomatoes, eggplants, and flowers in a caterpillar tunnel. Building a caterpillarThe hoops for a caterpillar tunnel can be galvanized steel, electrical conduit or pvc.

Adam NCAT Agriculture Specialists © NCAT 2008 IP142 This resource list discusses basic principles of solar greenhouse design, as well as different construction material options. Books, articles and Web sites, and computer software relevant to solar greenhouse design are all provided in a resource list. Table of Contents Introduction Since 2000, U.S. greenhouse growers have increasingly adopted high tunnels as the preferred solar greenhouse technology. Bradford Research and Extension Center: Building a Passive Solar Greenhouse. Wall O’ Water, 3-Pack - Garden Harvest Supply Inc. Wall O Water Plant Protectors and Season Extenders Wall O' Water plant protectors will keep your plants growing with temps down to 16°F.
Gardeners may be concerned that it is too cold at night if you plant 2 months before the last frost—but cold is good. You want it to freeze, as that is what makes the Plant Protector work. When the water in the Plant Protector freezes at night, it gives off 1.8 million calories of heat—half of which stays inside and keeps the plant warm. How to use the Wall O Water Plant Protector: Use an empty 5-gallon bucket as a frame to set up the empty Plant Protector, and then simply fill the tubes with water.
