The Riga 3 is 9'8\" wide × 10'6\" long × 7'7\" tall with 102 sq ft. Both share the same length and glazing system, but the Riga 3 is 2 feet wider and 6 inches taller — offering significantly more interior working space. The Riga 3s is the better choice for narrow lots or tight side yards where the extra width won’t fit.\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 3s base kit is a 6\" H × 92\" W × 126\" 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\u003eHow does the automatic roof opener work?\u003c\/strong\u003e\u003cbr\u003eThe automatic roof opener uses a wax-cylinder mechanism that expands and contracts with temperature changes — no electricity required. When the interior temperature rises above a set threshold (typically around 65–70°F), the opener automatically pushes the roof window open to ventilate. When the temperature drops, it closes automatically.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the Riga 3s handle heavy snow loads?\u003c\/strong\u003e\u003cbr\u003eYes — the “onion” arch profile sheds snow automatically. Snow slides off the curved surface rather than accumulating, preventing the structural loading that causes flat-roof greenhouses to collapse. The Riga 3s 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 and contains all the specialized tools needed for the build.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Riga 3s expandable?\u003c\/strong\u003e\u003cbr\u003eNo — the Riga 3s is a fixed-length model and cannot be extended. 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":59733992669470,"sku":"RIGA-IIIS-NOBASE","price":5099.0,"currency_code":"USD","in_stock":false},{"title":"No - Skip Foundation Frame \/ Add Premium Upgrade","offer_id":59733992636702,"sku":"RIGA-IIIS-UPG-NOBASE","price":7199.0,"currency_code":"USD","in_stock":false},{"title":"Yes \/ No Upgrade","offer_id":59517635199262,"sku":"RIGA-IIIS-FREEBASE","price":5099.0,"currency_code":"USD","in_stock":true},{"title":"Yes \/ Add Premium Upgrade","offer_id":59517635166494,"sku":"RIGA-IIIS-UPG-FREEBASE","price":7199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/1802\/5246\/files\/Riga_3s_exterior.png?v=1786398055","url":"https:\/\/rigagreenhousekit.com\/products\/riga-3s-7x10-greenhouse","provider":"Riga Greenhouses","version":"1.0","type":"link"}
