An editorial greenhouse site, not a garden center.

What we publish

We cover greenhouse buying decisions, brand and model comparisons, real all-in cost breakdowns, glazing and sizing guides, base and foundation guidance, structural-safety content, and a directory of the brands worth knowing. Backyard and serious-home-gardener buyers only. We don't cover commercial or production greenhouses, market-farm high tunnels, or industrial glasshouses, and pop-up plastic kits get thin coverage at most.

Why this site exists

Most greenhouse advice online is tied to a catalog or a commission. The “best greenhouse” lists rank whatever pays best and treat a $300 pop-up and a $15,000 glasshouse as the same purchase, the manufacturer pages sell you the pretty structure, and nobody leads with the part that decides the project: the kit price is not the project price. The base, the anchoring, and the ventilation are the parts that determine whether the thing lasts, survives a storm, and keeps your plants alive, and they're the parts nobody puts on the page.

Greenhouse Guide is built to be useful before it is commercial. That means real all-in numbers with the base broken out, named weaknesses on brands we otherwise like, and telling you when a $3,000 polycarbonate greenhouse on a proper base is the smarter buy than a five-figure glasshouse for how you actually garden.

How we think

We care about practical accuracy more than aspiration. On buying pages, we focus on all-in cost, glazing fit for your climate, size fit for your use, base and anchoring requirements, warranty terms, and long-term reliability. The right answer depends on how you'll garden and where you live, not on which greenhouse looks best in the catalog photo. And some of what we publish is structural and horticultural-loss content, which we hold to a stricter standard than anything commercial on the site.

Where we come from

Greenhouse Guide is part of an independent network of buying guides, built on the same rule: we don't sell the product, so we have no reason to push you toward one. Our nearest sibling is backyardoffice.guide, because the base, the permits, and the “is this a DIY kit or a real build” questions are shared, and because the right answer to “I want a greenhouse” is sometimes “you actually want a heated four-season room to work in”. When that's the answer, we say so and point you there.

What we are not

We are not your builder, your electrician, or your permit office. Greenhouse installation involves foundations, anchoring, electrical and water runs, and code and setback requirements that vary by state and municipality, and our guides describe that work so you can budget it and question a quote, never so you can do the licensed parts yourself. Our structural-safety guidance, wind-anchoring, snow-load, and glass, is deliberately conservative. Final purchase, siting, and structural decisions belong with licensed professionals and the manufacturer documentation.
