Basic Facts

Greenhouses work in myriad ways to nurture plants. They trap solar heat and energy through their glass or plastic housing. In these conditions, seedlings can be sprouted earlier, extending the growing season. The warmer environment also allow some plants to be grown and harvested year round, while other setups can help you overwinter your plants until the next spring. Added benefits include trapping moisture, encouraging a more humid environment, and protecting plants from pests and predators.

Sizes

Tabletop terrariums grow seedlings and plants indoors with chic style. Cold frames provide a healthy start for plants in small outdoor areas and can be easily moved.

Commercial structures can support a wide range of projects and ventures. Most of the larger houses arrive as kits that need to be assembled onsite.

Materials

Greenhouse wall and roof panels are usually made of glass or plastic. Polycarbonate panels with UV filters are a popular choice for durability and protection from the elements. Some designs are double-walled for added insulation. Portable and mini greenhouses often feature a polyethylene thermal film cover. Indoor terrariums and cold frames are usually constructed of glass or polycarbonate plastic. Greenhouse frames are made in a variety of materials, but are often aluminum and sometimes stake to the ground for stability.
