Solexx Greenhouses: Innovative, superior performance!

Solexx Hobby Greenhouses offers a user-friendly growing experience. Their spacious design with 36" aisles and full-length benches allows for comfortable movement and full utilization of the interior. The unique composite frame requires no maintenance, and the innovative Solexx panels provide optimal diffused light for flourishing plant life. Be sure to click here to read HINTS FOR INSTALLING SOLEXX for more detailed information on how Solexx is properly installed.

Solexx Greenhouses – Featuring Solexx Covering

  • Strong and shatterproof to protect against wind and snow
  • Solexx is White for a Reason — it produces an even, diffuse light proven to accelerate plant growth by up to 25%
  • Independent lab tests prove Solexx twin-wall insulated greenhouse material insulates better than even 8 mm polycarbonate to keep heating costs low

Cutting-Edge Framing

  • A combination of composite tubing (the same material used to make bridges), steel fittings, and PVC provides superior strength and stability against wind and snow
  • The white Solexx greenhouse framing reflects the greenhouse light — sending more light back to your plants. Dark frames absorb the light
  • Color-coded, pre-cut greenhouse frame makes assembly easy
  • Composite material does not transfer the cold into the greenhouse, unlike metal frames

Greenhouses feature built-in benches and hanging rods

  • Each wide, strong, full-length shelf holds up to 500 lbs so that you can fit a lot of plants in a small area
  • Steel-reinforced hanging rods run the length of the greenhouse, giving you the perfect spot to overwinter your hanging baskets

Ventilation for healthy plants!

  • Each greenhouse includes a louvered air vent for ventilation.

Greenhouse Covering

A versatile choice for both new and existing structures, Solexx's twin-wall design allows for easy installation in custom greenhouses, rejuvenation projects, or even carport conversions into sunrooms. This innovative material offers superior insulation, promoting stable temperatures for flourishing plants while reducing your heating costs.

Solexxâ„¢ Greenhouse Panels

  • Strong and shatterproof greenhouse covering protects against wind and snow.
  • Solexxâ„¢ greenhouse panels diffuse the light throughout the greenhouse for optimal plant growth.
  • The double-walled insulated greenhouse material helps hold in the heat.
  • 10-year limited UV warranty

Installation and Ordering Tips:

  • Solexx is flexible and can wrap around peaks and corners for a watertight seal
  • Solexx scores and cut easily – no power saw required
  • Installs both horizontally and vertically (unlike polycarbonate) for less waste
  • Available in pre-cut panels or custom length rolls up to 900′ long (fewer seams means better insulation and less work)
  • Two thicknesses: Use 3.5 mm for almost all applications. Choose 5 mm for high altitude, heavy snow areas.
  • Join panels together with optional H-Channel or, simply overlap the panels (panels are an extra 1″ for overlapping)
  • For optimum support, set studs or trusses 2′ apart on center

Solexxâ„¢ Custom Length Rolls
Custom cut to eliminate waste. Flutes run the length of the material for superior strength. Rolls are 4'1″ wide and as long as 900′.

  • GSR-160-CUT
    49.5″ x up to 900’L (3.5 mm)
  • GSR-240-50-CUT

Solexx Paneling Accessories

H-Channel and Clips

Flexible, snug fitting PVC H-Channel slides between Solexx seams for a flush finish and tight seal. Clips are used to join 4′ H channel pieces together for horizontal installations (Example: use an H-Clip to connect two 4′ H-Channels into an 8′ H-Channel).
GS-600, 4′ H-Channel
GS-600-C, H-Channel Clip
U-Trim and Caulking
U-Time PVC edging caps off open flutes of the panels. We recommend you first run about ¼ inch of silicone caulking into the open edges of the panels to seal out bugs, dirt, and moisture (click here to see a video). The trapped air from the caulking helps achieve the highest possible insulation.
GS-610, 4’1″ U Trim
GS-530, Clear 100&% silicone caulking, 10.1 fl oz
Solexx Sealing Screws
White galvanized screws with ¼" hex heads secure the greenhouse covering to the frame of the greenhouse. No pilot hole is required! Soft neoprene washers seal out moisture. Use 1″ screws for wood or PVC frames and 1″ self-drilling screws for metal frames. Screws are sold in packages of 100.
GS-500, 1″ wood screws
