Riga XL 5 Greenhouse – Exclusive Sale

The Riga XL –  14 ft. W x 16 ft. 5 in. L Greenhouse is designed to grow fresh vegetables, herbs, and flowers in the middle of winter. Other greenhouses use less than 8 mm panels, but the Riga XL 5 Greenhouse has 16 mm triple-wall polycarbonate panels. The Riga XL Greenhouse is the largest commercial quality hobby-kit type greenhouse now available in the country designed, engineered, and manufactured in Germany by Hoklartherm, with 28 years experience.

The polycarbonate glazing on the Riga XL 5 Greenhouse is believed to be of superior quality than the much more common Polygal or GE glazing. One major advantage of the Riga XL 5 Greenhouse's construction method is that the frame profiles are permanently attached to each other, and won't come loose over time due to wind pressures. With a combination of strong materials and durable hardware it is by far the strongest greenhouse of its size under $15,000.

Base Frame (optional)

  • Foundation Frame/Base: 5 in. H x 3 in. W
  • "C-shaped" Base sits in the ground and is the factory's preferred anchoring system
  • Simply dig a trench 6 in. (throw the dirt to the outside) place the Foundation Frame. Build the greenhouse and than back fill the trench and the Foundation Frame with the removed dirt. Stamp it down and no winds (except tornadoes or hurricanes) will remove the unit. This is an easier option than building your own frame.
