The RIGA XL is truly a greenhouse by the European definition of a greenhouse - designed to be used to grow fresh vegetables, herbs, and flowers in the middle of winter. Other "greenhouses" using less than 8 mm twin-wall polycarbonate are considered to be Season Extenders, to be used when only a slight night frost might be expected during the spring or fall. At best, they can only be used to house established plants during the winter season.

Why Choose RIGA XL?

  • 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 of experience.
  • The RIGA XL Greenhouse is an exceptionally strong greenhouse with strong materials and durable hardware.
  • 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 and won't loosen over time due to wind pressuress.
  • German engineering - guaranteed top quality!
  • Optional Shelving: Seedtray/Bench 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 enable the insertion of heavy-duty seed trays. This greenhouse can flex to your gardening needs throughout the year.
  • The RIGA XL Greenhouse is attractive and fits well into an upscale garden setting.
  • Buying a greenhouse is like buying a car; they vary in cost from cheap to very expensive; the RIGA XL is a class similar to a Volkswagen/Volvo – stronger, more durable, and better insulated, and offers many more features than the better selling brands.
  • 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.
  • We recommend you buy one size bigger than you planned.
  • Made in Germany
