Optional Accessories

Thicker Panels

Thicker (5mm) Panels

Price: $240.00 (free shipping)

Only necessary for very cold climates or areas with very heavy snowfall.

Base Vents

Base Vents

Price: $60.00 for six vents (free shipping)

Base vents are helpful in assuring that there is air continually flowing throughout your greenhouse. This will create cross-ventilation and will ensure proper air flow to prevent mold in damp climates, and keep the greenhouse cooler in hot climates. Each base vent is 4" H x 9" W.

Tie Down Kits

Tie Down Kit

Price: $45.00 (free shipping)

Tie down kits are used to anchor your greenhouse. Tie down kits will keep your greenhouse secure and stable even in the strongest winds. This tie down kit includes 6 anchors.

Solar Vent Opener

Solar Vent Opener

Price: $67.00 (free shipping)

The solar powered opener closes and opens the louver vent automatically in response to temperature changes. The piston is coated with a mineral wax that expands with a temperature increase. As the wax cools, the piston lowers and gradually closes your vent. Install this opener on the Easy-Flow Louver vent included in this greenhouse, and you won’t have to remember to open or close the vent if the temperature changes dramatically.

Wire Shelf Racks

Wire Shelf Racks

Price: $316.00 (free shipping)

This greenhouse comes with the shelf frames, but not the shelves themselves. Solexx makes powder-coated steel racks that fit neatly over the frames. These frames are very strong, drain water, and allow air to circulate. If you don’t want the added cost, you can lay boards across the frames to act as shelves. Includes all the shelving needed to cover the bench frames. (4.5) 29" x 47" side shelf units.

Exhaust Fan

Exhaust Fan with Thermostat

Price: $269.00 (free shipping)

Powerful exhaust fan for large spaces. If you’re in a warm climate, or have a problem with mold and need rapid air exchange in your greenhouse, consider using this exhaust fan.

Exhaust fan features:

  • Heavy-gauge galvanized steel frame reduces rust and corrosion.
  • Contains a thermally-protected motor.
  • Thermostat and wiring are included, 115v.
  • 760 CFM
  • Dimensions: 12" x 12" square

Solexx Frame:

Solexx greenhouse frames are made from a pultruded, strong composite material giving them the strength of steel without disadvantages like rust or corrosion. White color frame reflects light inside the greenhouse, so more light is available for your plants. The hanging rods and the bench frames are steel reinforced, and coated with a rust-proof finish. All Solexx greenhouses are freestanding, and do not need site preparation or special foundations – just level the ground and it's ready to assemble.

Solexx Panels:

Strong and shatter-proof, double-walled Solexx panels will protect your seedlings and plants from strong winds, hail, driving rain, snow, and frost. With these insulated Solexx panels, you will keep heating costs low, and you can extend your growing season from early spring to late fall. Unlike other greenhouse coverings, Solexx adds more than double the UV inhibitors, and it is added as the plastic is processed, so it is not just a coating. Solexx panels create an evenly diffused light, so all plants benefit from optimal growing conditions. Prevents your plants from ‘burning’ in the direct sun.

Solexx panels are available in 3.5mm or 5mm thickness. The 3.5mm panels are recommended in most areas because they provide more light transmission. The 5mm panels add support and are used in very cold climates (for added insulation) and for areas in high altitudes that experience very heavy snowfalls.

About Solexx:

Adaptive Plastics, manufacturer of Solexx greenhouses and greenhouse covering, was first introduced to corrugated polyethylene plastic in 1986 and began manufacturing insulated twin-walled fruit harvesting totes for growers. After experimenting with the corrugated plastic as a hot house covering and seeing how well tomato plants grew under the material, the idea to use the panels to design a hobby greenhouse kit was born. University testing verified that the flutes in the twin wall plastic diffuse the light and capture it from various angles – accelerating the growth of plants. From this background in plant science, they set out to design an affordable, strong, and practical greenhouse that would be easy to use for all gardeners – the Solexx Greenhouse.
