About Our Greenhouse Kits

Our handsome greenhouse kit.
The 8' x 12' greenhouse with automatic roof vent and Dutch door.
If you are looking for a convenient and lasting way to extend your gardening season, a greenhouse may be the solution. A well organized and functional greenhouse enables you to grow thousands of transplants at a fraction of the cost of buying them at a nursery. It also gives you the flexibility to choose what you grow rather than relying on what local nurseries want to provide. If your objective is to care for tender plants that need additional protection during the coldest months of year, a greenhouse is the easiest, most convenient and reliable way to do this.

Our greenhouses are designed to be aesthetically pleasing and functional at an affordable price. The materials have been chosen to produce a sturdy structure that is easy to assemble and maintain. Delivered in pre-assembled panels, most people can put the kits together in an afternoon using only a power screwdriver, a six-foot step ladder and a tape measure. The 6 x 8 and 8 x 12 models come with a video that takes you through the assembly process to make it as easy as possible.

Double-Wall Polycarbonate Glazing
The Best Greenhouse Glazing Material

polycarbonate double wall
  • Virtually unbreakable polycarbonate is the same high-tech plastic used in aircraft windshields and helmets. Temperature extremes don't affect its impact resistance. Hail and baseballs bound off. Its impact strength is 30 times greater than acrylic and 200 times greater than glass. After glass, polycarbonate is the most flame resistant glazing

  • Double-wall panels retain heat to help plants stay 10-20 deg.F warmer in winter. If you use a heater, you'll save 40% of the cost of heating a single-pane glass greenhouse.

  • Design maximizes the quality of light for full, straight and even plant growth. Sunlight is scattered by the ribs between panel walls to surround plants without shadowing or burning them.

  • UV-resistant additive in panels blocks 98% of the harmful UV rays while transmitting 83% of the visible rays that plants need for maximum growth. Plants are more productive. Glazing carries a 10 year limited warranty against hazing and discoloration.

  • Panels won't crack or shatter. They may be cut with a fine toothed saw, allowing easy installation of plumbing or heating equipment.

Automatic Ventilation Simplifies Climate Control

roof vent Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65 deg.F. As it cools and the paraffin contracts, the operator's springs draw each vent closed. It is adjustable within approximately 5 deg.F and easily detachable for manual operation.
