  • The RIGA XL Greenhouse is designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, sunrooms, pavilions, pool covers, home additions, and commercial building, with 28 years experience.
  • With a combination of strong materials and durable hardware, the RIGA XL Greenhouse is an exceptionally strong greenhouse.
  • The RIGA XL Greenhouse offers more window and door ventilation than other units in its class.
  • The 16mm triple-wall polycarbonate glazing on the RIGA XL Greenhouse is German-made and believed to be of superior quality than the much more common Polygal or GE glazing.
  • One major advantage of the RIGA XL’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.
  • German engineering – guaranteed top quality!
  • Optional Shelving: Seed tray shelf and top shelf are available with strong diagonal support braces – can hold a 160 pound man! Twin-wall polycarbonate shelf inserts can be removed to allow for tall plants such as tomatoes or beans or to allow insertion of heavy-duty seed trays. This greenhouse can flex to your gardening needs throughout the year.
  • The RIGA XL Greenhouse is attractive and beautiful to look at – fits well in to an upscale garden setting.
  • The RIGA XL Greenhouse offers the insulation needed to grow plants year-round – others using less insulation cost too much to heat.
  • RIGA XL Greenhouse units are available in 5 sizes.
