Grow beautiful plants in any season and get a jump start on your veggie garden with this great looking greenhouse! These GardenHouse Kits are ideal for small scale use. They combine top quality components and functional design.

Attractive and durable redwood frames

  • Naturally resistant to insect and moisture damage
  • Use only second growth redwood to preserve old-growth redwood
  • Immune to rot, impervious to termites and won't split or warp

Roof slope and strength

  • 45° roof slope transmits low angle sun in the winter, and reflects high angle sun in summer.
  • Steep roof slope sheds snow in the winter and can withstand a snow load of 18 lbs per square foot.
  • Provides ample headroom and plant-hanging space.
  • Height to peak is 8'4" for Mt. Hood series and 10' for Mt. Rainier series

No foundation required

  • Simply prepare a flat surface of gravel, wood, cement, or other material as indicated.
  • So lightweight that with a few helping hands it can be moved seasonally.
  • Durable plastic frame base with the authentic look, color and texture of redwood, but with the consistent properties of plastic, making it resistant to insect and moisture damage.

Double-wall polycarbonate panels

    Panels will not crack or shatter
  • Retain heat in winter, diffuse light for even plant growth and block 98% of harmful UV rays.
  • The twin-walled, ribbed, translucent polycarbonate has 30 times the impact strength of acrylic and 200 times that of glass.
  • Patented rigid tie connectors make the structure rigid and strong.
  • Treated with a UV coating to prevent discoloration.
  • An independent verified that the GardenHouse withstood their maximum wind load capacity of 85 mph with no damage.
  • Wall height is 5'4"

Vents with automatic vent operators

  • Mt. Hood series has one roof vent and one back wall vent. Mt. Rainier series has two roof vents and two back wall vents
  • Vent openers contain a paraffin (wax) cylinder that expands when the temperature reaches about 65°F, pushing the vent open to its fully opened position at about 85°F. As the temperature cools and the paraffin contracts, the vent operators' springs draw each vent closed.
  • It is also easily detachable for manual operation.
  • A circulating chimney effect is created as cool air is drawn in from the base vent, and warmer air is allowed to escape from the hottest point at the roof ridge.

Assembles easily and quickly. Major kit components are panelized for an easy sure fit. Each kit comes with easy-to-follow instructions, and a convenient product assembly video. All parts are pre-fabricated and can be assembled in less than a day with the aid of a power (Phillips) screw driver, a 6' step ladder, a 12' tape measure and 4 tubes of clear silicon caulking.

Dutch door entry provides additional ventilation control and access.

Optional bench kits can be purchased separately and has free shipping when shipped with the greenhouse.

5 year warranty on parts.

Beautiful Greenhouse

The greenhouse assembly was quick and easy. The greenhouse looks beautiful in our garden. We live in Zone 7 and our winters are cold, but this greenhouse is perfect for keeping everything warm all winter and for getting our starts going in early spring. Automatic vent openers are perfect in the summer to keep the greenhouse ventilated and cool. We also made sure to put down a thick layer of weed fabric under the foundation to keep weeds at bay. The greenhouse is a great addition to our garden!

Looks great after 7 yeras

This is an excellent product. We bought it 7 years ago (2004) and today, it stands and works as well as the day we put it together. We use it year around. If you are new to using a green house, consider the size carefully. Once you start using one, you'll find all sorts of uses for it. We wish we had bought the next size up.
