It features a distinctive curved \"onion\" arch profile, 8mm and 10mm twin-wall polycarbonate glazing, 4 automatic roof vents, and a 15-year frame warranty. At 165 sq ft, it’s designed for serious year-round growing in all climates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Riga V a true four-season greenhouse?\u003c\/strong\u003e\u003cbr\u003eYes. The Riga V is engineered for year-round use, not just season extension. The 8mm polycarbonate panels provide an R\/K-value up to 1.89, the no-eaves arch profile sheds snow naturally, and the structure is wind-tested to 100 mph. With supplemental heating in colder climates (USDA zones 4–6), it can maintain frost-free growing conditions year-round.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the base kit required?\u003c\/strong\u003e\u003cbr\u003eA proper foundation is required for structural integrity and warranty compliance. The Riga base frame (+$1,749) is the recommended solution and is designed specifically for the Riga V footprint. Without the base kit, you will need to provide an alternative foundation (concrete pad or equivalent). The base kit is highly recommended for most installations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the anchor option include?\u003c\/strong\u003e\u003cbr\u003eThe anchor option (+$99.99) includes ground anchors that secure the Riga V base to the ground for improved wind resistance. It is particularly recommended for exposed sites or areas with regular high winds. The Riga V is wind-tested to 100 mph when properly anchored.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the Premium Upgrade?\u003c\/strong\u003e\u003cbr\u003eThe Premium Upgrade is an available add-on for the Riga V.

The Riga V is 165 sq ft (9'8\" × 17'6\") and is not expandable, but is wider — giving more usable width per row. The Riga V is typically less expensive than the Riga XL. Choose the Riga XL if you want expandability; choose the Riga V if you want maximum width in a fixed-length structure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does assembly take?\u003c\/strong\u003e\u003cbr\u003eAssembly takes approximately one full day for two people. Written instructions are included. No specialized tools are required, but having two people is strongly recommended for panel handling and frame alignment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the warranty on the Riga V?\u003c\/strong\u003e\u003cbr\u003eThe Riga V includes a 15-year warranty on the aluminum frame and a 10-year pro-rated warranty on the polycarbonate panels. These are among the strongest warranties available on residential greenhouse structures and reflect the quality of German manufacturing.\u003c\/p\u003e","brand":"Exaco","offers":[{"title":"No - Skip Foundation Frame \/ No Upgrade","offer_id":59734439428382,"sku":"RIGA-V","price":8999.0,"currency_code":"USD","in_stock":false},{"title":"No - Skip Foundation Frame \/ Add Premuim Upgrade","offer_id":59734439395614,"sku":"RIGA-V-UPG","price":11749.0,"currency_code":"USD","in_stock":false},{"title":"Yes \/ No Upgrade","offer_id":59517644439838,"sku":"RIGA-V-BASE","price":10748.0,"currency_code":"USD","in_stock":true},{"title":"Yes \/ Add Premuim Upgrade","offer_id":59517644407070,"sku":"RIGA-V-UPG-BASE","price":13498.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/1802\/5246\/files\/Riga_3.3.webp?v=1786470644","url":"https:\/\/rigagreenhousekit.com\/products\/riga-v-9x17-greenhouse-german-made","provider":"Riga Greenhouses","version":"1.0","type":"link"}
