It features a black powder-coated aluminum frame, crystal-clear 6mm polycarbonate front, and 8mm\/10mm twin-wall polycarbonate sides and rear panels. Rated to 100 mph winds with automatic roof vents for year-round climate control.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the Riga V Black differ from the Riga IV Black?\u003c\/strong\u003e\u003cbr\u003eThe Riga V Black adds 3'6\" of length and 30 sq ft of growing area over the Riga IV Black, making it the largest standard Riga model before the XL series.

The \"onion\" arch profile sheds snow automatically and the structure is tested to 100 mph winds. When properly anchored, the Riga V Black excels in cold-climate, four-season use.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does assembly take?\u003c\/strong\u003e\u003cbr\u003eApproximately one to two days for two people.
