It delivers the same German engineering, 8mm\/10mm twin-wall polycarbonate glazing, automatic roof opener, and 15-year frame warranty as the larger Riga models. The 54 sq ft footprint is compact but functional — sufficient for seedling propagation, overwintering tender plants, and year-round growing of herbs, greens, and small vegetables.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between the Riga 2s and the Riga 3s?\u003c\/strong\u003e\u003cbr\u003eThe Riga 2s is 7' long (54 sq ft); the Riga 3s is 10'6\" long (81 sq ft). Both are 7'8\" wide and share the same glazing, frame, and warranty. The Riga 3s adds 27 sq ft of growing area for approximately $500 more. If your site can accommodate the extra length, the Riga 3s is the better long-term value. Choose the Riga 2s if you have a strict 7-foot length constraint.\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. It is a ground-installation frame buried in a trench and backfilled with soil to anchor the greenhouse and raise the interior height. 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 2s handle heavy snow loads?\u003c\/strong\u003e\u003cbr\u003eYes — the “onion” arch profile sheds snow automatically. The Riga 2s 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\u003eIs the Riga 2s expandable?\u003c\/strong\u003e\u003cbr\u003eNo — the Riga 2s is a fixed-length model. If you anticipate needing more space in the future, consider starting with the Riga 3s (same width, longer) or the Riga XL series (expandable by adding sections).\u003c\/p\u003e","brand":"Exaco","offers":[{"title":"No - Skip Foundation Frame \/ No Upgrade","offer_id":59733986803998,"sku":"RIGA-IIS-NOBASE","price":4699.0,"currency_code":"USD","in_stock":true},{"title":"No - Skip Foundation Frame \/ Add Premium Upgrade","offer_id":59733986836766,"sku":"RIGA-IIS-UPG-NOBASE","price":6598.0,"currency_code":"USD","in_stock":true},{"title":"Yes \/ No Upgrade","offer_id":59733956395294,"sku":"RIGA-IIS-FREEBASE","price":4699.0,"currency_code":"USD","in_stock":true},{"title":"Yes \/ Add Premium Upgrade","offer_id":59733956428062,"sku":"RIGA-IIS-UPG-FREEBASE","price":6598.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/1802\/5246\/files\/riga_2s.jpg?v=1786469171"},{"product_id":"riga-ivs-7x14-greenhouse","title":"Riga 4s 7x14 Greenhouse","description":"\u003ch2\u003e\u003cstrong\u003eRiga 4s (Riga IVs) 7x14 Greenhouse\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eRiga 4s\u003c\/strong\u003e is the narrow-width 14-foot model in the Riga series — 108 sq ft of growing area in the compact 7'8\" wide footprint of the IIs\/IIIs series, extended to 14 feet in length.

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 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.

The Riga III is the entry point to the wider 9'8\" Riga series, offering significantly more interior headroom and working width. Both are non-expandable and use the same German manufacturing and polycarbonate glazing system.\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. It is a 6\" H × 116\" W × 126\" D aluminum frame that is 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 and the warranty may be affected. If you are installing on an existing concrete pad, the anchor option may be more appropriate than the base kit.\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. It requires no power and no manual adjustment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan the Riga III handle heavy snow loads?\u003c\/strong\u003e\u003cbr\u003eYes — the “onion” arch profile is specifically designed to shed snow. Snow slides off the curved surface rather than accumulating, which prevents the structural loading that causes flat or low-pitch greenhouse roofs to collapse. The Riga III has been tested against winds up to 100 mph and has never been blown away when properly anchored with the base kit or anchor option.\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 III expandable?\u003c\/strong\u003e\u003cbr\u003eNo — the Riga III is a fixed-length model and cannot be extended.
