Riga 2s 7x7 Greenhouse

Riga 2s (Riga IIs) 7x7 Greenhouse

The Riga 2s is the smallest and most affordable model in the Riga greenhouse series — the entry point to German-engineered, year-round growing. At 54 sq ft in a 7'8" × 7' footprint, it is designed for beginner gardeners, urban growers, and anyone who wants a serious winter greenhouse in a compact space. Engineered and manufactured in Germany by Exaco with 28 years of experience, the Riga IIs features the same “onion” arch profile, 8mm/10mm twin-wall polycarbonate glazing, automatic roof opener, and 15-year frame warranty as the larger Riga models — in the most space-efficient package in the lineup.

Dimensions & Growing Area

Riga Series Comparison - Which model is best for you?

The Riga 2s is the most affordable entry point to the Riga series. If you need more length in the same narrow footprint, the Riga 3s extends to 10'6" for $540 more. If you need more width and headroom, the Riga 3 steps up to the 9'8" wide series for $810 more. All models share the same German manufacturing, glazing system, and warranty.

Frequently Asked Questions

Is the Riga 2s a good starter greenhouse?
Yes — the Riga 2s is the most affordable model in the Riga series and an excellent first greenhouse for serious growers. 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.

What is the difference between the Riga 2s and the Riga 3s?
The 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.

Do I need the base kit (foundation frame)?
The 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. 

How does the automatic roof opener work?
The 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.

Can the Riga 2s handle heavy snow loads?
Yes — 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.

Is the Riga 2s expandable?
No — 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).
