Mt. Hood models are six feet wide with plenty of headroom at 8'4" tall at the peak. Narrow enough to fit in a limited space, each kit is made with a clear natural redwood frame, twin wall polycarbonate and includes two vents with automatic vent openers, Dutch doors and a base made with recycled plastic.

With up to four optional benches, you can optimize your space no matter what you want to grow. If you are not sure which size is best, remember you can extend the both the 6' x 4' and 6' x 8' model at a later date by four feet with our extension kit.

With our pre-assembled panels, you can easily assemble your greenhouse in just a short time--a 6' x 8' model, one of our most popular, takes two people about three to four hours to complete.

Each kit includes easy to follow printed instructions, clearly labeled panels, as well as an assembly video.

Automatic Vents Simplify Climate Control


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°F, pushing the vent open to its fully opened position at about 85°F. As it cools and the paraffin contracts, the operator’s springs draw each vent closed. It is adjustable within approximately 5°F and easily detachable for manual operation.

Redwood Bench Kits


Specially designed matching redwood benches are available that run the full length of the Sunshine GardenHouse.. Benches are 21″ deep for all Mt. Hood models.  Up to 4 benches can be used in each GardenHouse.


Great looking and durable redwood 2"x2" frames are naturally resistant to insect and moisture damage, and use only second growth redwood to preserve old-growth redwood. They immune to rot, impervious to termites and won't split or warp

45° roof slope transmits low angle sun in the winter, and reflects high angle sun in summer. 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 and sheds snow in the winter easily.

Provides ample headroom and plant-hanging space.

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.

NOTE: I have done this, including putting it over a fence. The 6x8 requires 4 to move it and 6 is recommended for lifting over a fence. If you have teenagers at home (which we did) this is a great time to bribe them with pizza to bring in thier friends.

Assembles easily and quickly. By far the easiest of the many greenhouse kits that I have built at our retail garden center. 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.

Double-wall polycarbonate panels will not crack or shatter, they retain heat in winter, diffuse light for even plant growth and block 98% of harmful UV rays. The double-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.

We did our own wind test with this using a small aircraft. Best guess from standing in front of the prop right beside the greenhouse holding a wind meter was in the 70-80 mph range.

Once we got it (lost in shipping for a week) put it together. Not as easy as the video showed, as various pieces didn't match up, had to do some minor reengineering. some parts were poorly assembled at factory, had to take apart and reassemble correctly. Once this was done though, materials were of high quality, and the greenhouse is nice and quite functional.
