Why a greenhouse

You did not buy a greenhouse. You bought a longer growing season.

Outdoors, the calendar decides what you can grow and when it ends. Inside a warm, sheltered room the rules change. You start earlier, you finish later, and the tender crops that sulk in the open finally ripen. It is the same six feet of garden, working months longer.

Good questions

Everything you might ask.

Will it withstand wind and snow?

Fix all four ground anchors to level ground and the slant corner supports brace the frame against wind. Clear heavy snow from the apex roof as you would any garden structure, and the pitched roof helps it slide. Anchoring is the single most important step, so follow the guide closely.

Does the polycarbonate yellow over time?

The panels carry a UV-protected outer coating that resists yellowing and keeps light transmission stable for years of normal outdoor use. Wipe them down each season to keep them clear.

How hot does it get in summer?

The hinged roof vent lets hot air rise and escape while the sliding door draws cooler air in low down, creating real cross-flow. On the hottest days open both, and add the temperature-triggered auto-vent opener so it manages itself while you are away.

Do I need a foundation?

No concrete base is required. You need reasonably level ground, then the four included ground anchors fix the frame down. A firm, level surface such as paving, compacted earth or a timber base all work well.

How hard is assembly?

Two people can put it together in about a day using basic hand tools. The panels and frame are pre-cut and the guide walks you through each step in order. Take your time squaring the base and the rest follows.

Can I heat it in winter?

Yes. The twin-wall polycarbonate holds daytime warmth into the night, and you can add an electric or paraffin greenhouse heater for hard frosts. Many growers keep tender plants going through winter this way.

Do I need planning permission?

Rules vary by locale and by how you site the structure. Many gardens do not require permission for a greenhouse this size, but always check with your local authority before you build.

What is the returns policy?

You have 30 days. If the greenhouse is not right for you, contact us for a return and a full refund, and we cover the return shipping.
