Why Trust Greenhouse Score

Microclimate First, Not Catalog First Our recommendations start with your weather, exposure, and crops. The Four Seasons Score was built to reflect what actually fails in the field—snow load, uplift, venting bottlenecks, UV fatigue—and what makes a greenhouse thrive: passive heat management, robust anchoring, and serviceable parts.

Transparent, Replicable Methods We publish our test protocol, instruments, and data notes so you can understand how a kit earned its score. Each review includes confidence bands, known limitations, and context-specific advice (e.g., alternate anchoring for coastal winds).

Independent and Uncompromised Brands cannot buy placements or influence outcomes. We disclose how we source products and how we fund the work. Affiliate links, when present, never change scores—and we’ll tell you when a product is unavailable or better options exist.

Field-Proven Guidance Our team blends horticulture, structural engineering, energy/controls, and hands-on builds. We validate claims across zones 3–10 and publish real assembly times, common failure modes, and fix paths. The result: fewer surprises, safer structures, and steadier harvests.

Total Cost and Longevity in View We favor designs that last—thicker glazing when warranted, better fasteners, smarter vent strategies—paired with honest lifetime cost and spare-part availability. Buy once, grow for years.
