Affiliate disclosure

Greenhouse Compare contains affiliate links. This page explains how they work and how we keep our scores independent.

How we earn money

Many links on this site carry an affiliate code. When you buy through one of them, we earn a commission from Amazon and other retailers. You pay the same price. As an Amazon Associate we earn from qualifying purchases.

Every affiliate link carries rel="nofollow sponsored", as Google asks.

Does commission change our picks?

No. We score every greenhouse from the maker's specs and buyer reviews with fixed rules (see How we score), whether or not a retailer pays us for it.

Our promises

• No paid rankings. No maker can buy a better place.
• Real downsides. We name the weak points, even on models that pay a higher commission.
• Dated pages. Every guide shows when we last updated it.
• No lab tests. We do not put the greenhouses up ourselves and we never claim to.
• Corrections welcome. Found a mistake? Email us.
