The Riga 4s is 7'8\" wide × 7'1\" tall (108 sq ft); the Riga IV is 9'8\" wide × 7'7\" tall (135 sq ft). The Riga 4s is the right choice for narrow lots where the wider Riga 4 won’t fit. If width is not a constraint, the Riga 4 offers 27 more sq ft of growing area and 6 more inches of peak height for approximately $630 more.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the Riga 4s have two roof windows?\u003c\/strong\u003e\u003cbr\u003eThe 14-foot length requires two roof windows to provide adequate ventilation across the full interior. A single roof window would leave the far end of the greenhouse with insufficient airflow on hot days. The two automatic openers work independently, allowing the greenhouse to self-regulate temperature along its full length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need the base kit (foundation frame)?\u003c\/strong\u003e\u003cbr\u003eThe base kit is strongly recommended for soil or lawn installations. The Riga 4s base kit is a 6\" H × 92\" W × 168\" D aluminum frame buried in a trench and backfilled with soil to anchor the greenhouse and raise the interior height by 6\". Without a proper foundation, the greenhouse may shift over time. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the Riga 4s handle heavy snow loads?\u003c\/strong\u003e\u003cbr\u003eYes — the “onion” arch profile sheds snow automatically. The Riga 4s has been tested against winds up to 100 mph and has never been blown away when properly anchored.\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. The Riga assembly facilitation kit (metric tape, 10mm wrenches, ratchet straps, Boss 399 silicone caulk, window restraint cables) is available separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Riga 4s expandable?\u003c\/strong\u003e\u003cbr\u003eNo — the Riga 4s is a fixed-length model. If you anticipate needing more space in the future, consider the Riga XL series, which is designed to be expandable by adding additional sections.\u003c\/p\u003e","brand":"KGT\/Hoklartherm","offers":[{"title":"No - Skip Foundation Frame \/ No Upgrade","offer_id":59734378152222,"sku":"RIGA-IVS-NOBASE","price":5599.0,"currency_code":"USD","in_stock":false},{"title":"No - Skip Foundation Frame \/ Add premium upgrade","offer_id":59734378184990,"sku":"RIGA-IVS-UPG-NOBASE","price":7949.0,"currency_code":"USD","in_stock":false},{"title":"Yes \/ No Upgrade","offer_id":59517634806046,"sku":"RIGA-IVS-FREEBASE","price":5599.0,"currency_code":"USD","in_stock":true},{"title":"Yes \/ Add premium upgrade","offer_id":59517634773278,"sku":"RIGA-IVS-UPG-FREEBASE","price":7949.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/1802\/5246\/files\/riga_4s_grandma.jpg?v=1786468196","url":"https:\/\/rigagreenhousekit.com\/products\/riga-ivs-7x14-greenhouse","provider":"Riga Greenhouses","version":"1.0","type":"link"}
