Riga IIIS Greenhouse Kit 

This top of the line German hobby greenhouse provides the most efficient design for year-round use. A special sloped roof provides maximum head room, but prevents snow build-up. Hail bounces off and the design allows heavy winds to blow right over the unit. Made with German precision engineering from heavy duty aluminum profiles and 8mm & 10mm UV coated Twin-wall Polycarbonate Glazing, this greenhouse offers the best insulation in its category, R-factor 3.0-3.2, and uses less energy than other hobby greenhouses to heat. The unique design has the best ratio between framing and polycarbonate panels, which allows for maximum light transmittance and less "moving" shade. Unit comes with an oversized rear wall window, one oversized roof window with automatic opener, an extra large Dutch barn style front door with lock, two full-length suspended shelves and an aluminum base to anchor the unit in the ground. One day assembly requires two people.
