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. This greenhouse is designed, engineered and manufactured in Germany by Hoklartherm, Germany's leading manufacturer of greenhouses. 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. The 16mm triple-wall polycarbonate glazing on the RIGA XL Greenhouse is of superior quality than the much more common Polygal or GE glazing. Optional Shelving Seedtray/Bench shelf and top-shelf are available with strong diagonal support braces. The 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. With a combination of strong materials and durable hardware, the RIGA XL Greenhouse is an exceptionally strong greenhouse that offers more window and door ventilation than others. This greenhouse can flex to your gardening needs throughout the year. The RIGA XL Greenhouse units are available in 5 sizes.
