Graphic showing the inside and outside of the Riga Greenhouse Kit from Hoklartherm with little round images about the features.Why Buy a Riga Greenhouse?

  • Its special shape is designed to offer optimal headroom inside, but with enough slope on the outside so that heavy snow loads slide down and severe wind blows right over
  • Comes with a large Dutch barn style door – with key & lock
  • Unique design of the Riga Greenhouse Kit has the best ratio between aluminum framing and polycarbonate panels, which allows for maximum light transmittance and less “moving” shade
  • Comes standard with an oversized rear-wall window for better ventilation
  • Riga S & L: 8 mm twin-wall polycarbonate glazing as side panels & 10 mm twin-wall polycarbonate glazing in the front and back walls
  • Riga XL: 16mm triple-wall polycarbonate on all sides
  • Compared to the Riga S line, the Riga L and XL has more headroom and space in square feet
  • Designed, Engineered, and Manufactured in Germany with 30 years of experience

Riga greenhouses are perfect for you if you…

  • Want a well-engineered greenhouse: Made in Germany
  • Want to grow plants year-round: Riga S & L has 8-10mm Polycarbonate glazing, Riga XL has 16mm Polycarbonate
  • Need a greenhouse that has to survive heavy snow loads and wind
  • Are looking for a long warranty: 10 years on Polycarbonate, 15 years on frame
  • Want great insulation on your greenhouse: Heavy-duty rubber seals and Silicon caulk around windows
  • Need more light for your plants: The shape optimizes the incidence of light
  • Want the perfect growing environment for your plants: Riga provides a great light diffusion and ventilation with roof vents, automatic vent openers, barn-style doors, and a rear wall window
