Solar Greenhouses
November 24th, 2007 | by admin |Solar greenhouses collect and store solar energy. This keeps your plants warm at night and when the weather is cold and cloudy. Passive solar greenhouses combine solar energy with other forms of heating to keep your greenhouse warm during the coldest months. You can make indoor trellises out of coat hangers. Get creative and bend them into different shapes, like stars or hearts, and put them into your pots.
