Exaco vs Solexx Greenhouses: An In-Depth Comparison

Spend $5,000 on the wrong greenhouse and you live with the regret for two decades, because a quality greenhouse is built to last that long. Exaco and Solexx sit at opposite ends of the same shelf: Exaco builds premium European glass and polycarbonate structures with Victorian styling, while Solexx makes value-priced twin-wall polyethylene kits engineered to spread soft, even light across your plants. Both lines are in stock, so this comes down to what you actually need. Here is how the two compare across eight factors that decide the purchase, drawing on the live greenhouse lineup that carries both brands.

TL;DR: Choose Exaco for a premium, decorative greenhouse built from 4mm tempered glass or 8-10mm twin-wall polycarbonate with Victorian styling and a 15-20+ year lifespan ($5,609 to $7,999 for the picks here, as of 2026). Choose Solexx for an easy-to-assemble, value-priced kit whose 5mm twin-wall polyethylene diffuses sunlight beautifully ($4,736 to $7,044). Exaco wins on looks and durability; Solexx wins on price, light diffusion, and assembly.

Quick Verdict: Which Should You Buy?

Choose Exaco if you want a decorative centerpiece, the durability of tempered glass or thick German polycarbonate, and a structure rated for snow and wind. The Hoklartherm Riga 3S at $5,609 is the practical entry point, and the Janssens Junior Victorian at $7,999 is the showpiece.

Choose Solexx if you want to spend less, assemble it yourself in a day or two, and grow under soft diffused light that reduces leaf scorch. The Garden Master 8x8 at $4,736 covers a serious home garden, and the Gardener’s Oasis 8x16 at $7,044 scales up for year-round growing.

Both brands build greenhouses that last 15-20+ years with care, so neither is a mistake. The decision hinges on one variable: do you value premium materials and decorative styling, or value, light quality, and a fast build?

Exaco vs Solexx: Comparison Table

Every cell below is drawn from the manufacturer specs for the in-stock models. Where a figure is not published, the cell says so rather than guessing.

Exaco: Premium Glass, Victorian Styling, Built to Last

Exaco distributes German Hoklartherm (the Riga polycarbonate line) and Belgian Janssens (the Victorian glass line), both made in Europe to durability standards that show up in the warranty and the weight. As of 2026, the in-stock picks run $5,609 to $7,999, putting Exaco at the premium end of this matchup. You pay more, and you get more structure for it.

The covering is the headline. The Janssens Junior Victorian uses 4mm tempered safety glass over an aluminum frame, with 5-foot side walls climbing to an 8-foot-2 peak, a sliding door, and integrated gutters, and it carries TÜV and GS certification. At $7,999 it is a decorative greenhouse first and a growing structure second, the kind of piece that anchors a garden. For polycarbonate buyers, the Hoklartherm Riga 3S gives you 81 square feet under 8mm and 10mm twin-wall panels, an automatic roof opener, and a lockable 30-by-72-inch door for $5,609.

Glass transmits roughly 90% of light, more than the 83% typical of polycarbonate, according to the Royal Horticultural Society’s guide to choosing a greenhouse. That clarity is part of the appeal, though it also means more direct sun reaching the leaves. With an aluminum frame and tempered glass or thick German poly, an Exaco greenhouse is built to last 15-20+ years with reasonable maintenance. The trade-off is assembly: these are detailed structures, and several owners report the build takes patience, expertise, and ideally a second set of hands.

Solexx: Soft Diffused Light, Easy Build, Better Value

Solexx, made by Adaptive Plastics, takes a different path: twin-wall polyethylene covering engineered to diffuse light rather than transmit it clear. As of 2026, the in-stock picks run $4,736 to $7,044, undercutting the Exaco picks while delivering a genuinely different growing environment. This is the value-and-light-quality choice.

Diffused light is the real selling point, not marketing gloss. The University of Massachusetts Extension notes that diffused light reaches lower leaves and reduces scorching compared with direct transmission, which is exactly what the Solexx covering is designed to do. The result is a soft, even glow with fewer hot spots, so plants in the back and bottom of the bench get usable light too. The 5mm twin-wall on the Garden Master 8x8 also traps air between its walls for steady warmth, giving you 6-foot-6 walls rising to an 8-foot-9 peak for $4,736.

Assembly is where Solexx pulls clearly ahead. The panels are pre-cut and lock together, so a typical build runs hours to a day or two rather than the longer, fiddlier Exaco process. For more room, the Gardener’s Oasis 8x16 stretches the same diffusion covering across a large footprint for year-round growing at $7,044. Solexx greenhouses also stand up to weather: the flexible twin-wall polyethylene and aluminum frame handle snow and wind loads, and the covering can last over 20 years.

Head-to-Head: Which Wins for Your Situation

You want a decorative showpiece. Exaco, easily. The Janssens Victorian glasshouse styling has no equal in the Solexx range. For a greenhouse that doubles as garden architecture, the $7,999 Junior Victorian is the pick.

You are on a budget or building it yourself. Solexx. At $4,736 the Garden Master 8x8 costs less than any in-stock Exaco here, and its lock-together panels mean you are growing in a day or two instead of wrestling a glass kit over a weekend.

You grow tender plants or seedlings that scorch. Solexx. The diffused light spreads evenly and softens harsh midday sun, which protects sensitive foliage and feeds lower leaves better than clear glass.

You face hard winters with snow and wind. Either, with an edge to Exaco’s heaviest builds. Both are rated for snow and wind, but Exaco’s thick twin-wall poly Riga models and tempered-glass Janssens frames are engineered for demanding climates. Solexx holds its own thanks to flexible polyethylene that flexes under load instead of cracking.

You want maximum clear light for sun-loving crops. Exaco. Glass transmits more total light than polyethylene, so tomatoes, peppers, and other heat-and-light lovers thrive under it.

FAQ

Where can I buy Exaco and Solexx greenhouses?

Both brands are in stock and ship directly. Browse our polycarbonate greenhouse range for the Hoklartherm Riga line and the Janssens glass models, and find the Solexx Garden Master and Gardener’s Oasis kits in the hobby greenhouse range. Buying through an authorized dealer keeps the manufacturer warranty intact.

Can Solexx greenhouses handle snow and wind?

Yes. Solexx greenhouses pair an aluminum frame with flexible 5mm twin-wall polyethylene that flexes under load instead of cracking, so they hold up to snow and wind. As with any greenhouse, anchor it properly and clear heavy snow from the roof. In severe-winter regions, confirm the model’s rated snow load against your local code before you build.

What are common Exaco and Solexx assembly mistakes?

The biggest one is starting on ground that is not level, which throws off panel alignment and door fit on both brands. For Exaco’s glass kits, rushing panel seating and skipping the listed hardware sequence causes the most frustration. For Solexx, forcing the lock-together panels rather than easing them into place can damage edges. Read the manual fully first, and have a second person help.

Ready to choose? Compare the in-stock Janssens and Hoklartherm models in the Exaco collection, or pick a Solexx Garden Master or Gardener’s Oasis for soft diffused light at a friendlier price. Either way, you are getting a greenhouse built to grow with you for 15-20+ years.
