Do I need a concrete foundation?

No 👍. The greenhouse is fixed directly into the soil with ground anchors. A wooden or concrete base is optional.

Can I transport the greenhouse in a car?

Yes 👍. The longest package is only 2 m, so it fits in most passenger cars.

Will the greenhouse survive snowy winters?

Yes. Thanks to the arched design and galvanized frame, the greenhouse is stable and resists snow and rain accumulation.

  1. Love the size. One box arrived a bit dented but all parts inside were fine. Assembly took us longer than expected (we are slow 😄) but end result is awesome.

  2. Feels premium

    Frame is thick galvanized steel and the whole thing feels stable. Doors on both ends with windows = easy ventilation. Packaging was good, nothing cracked. I’m super happy with the purchase.

  3. Great quality overall. We went with 4 mm + 1 m spacing (mild climate) and it’s still very solid. Manual is ok but could use a few more pictures. Customer service was friendly though.

  4. So much space

    This 4 m wide greenhouse is a game changer. The extra headroom (2.3 m) makes it comfortable to walk and work, and I can grow taller plants without bending them. Built with two people in a day. Worth it.
