Editorial Policy
Clear standards, explicit tradeoffs.
We prefer useful over comprehensive, and accurate over flattering.
Research approach
We use a mix of manufacturer documentation, product pages, published specifications, engineering and wind and snow-load standards, horticultural references, and editorial synthesis. For buying content we add owner reports from Facebook groups, GardenWeb and Houzz forums, YouTube tour comments, and verified purchase reviews, because that is where the second-winter truth lives. All-in cost figures come from real quotes and installer input, are dated on the page, and get re-verified on a schedule, not just on complaints.
How we evaluate products and brands
We judge greenhouses and brands on fit, not on abstract prestige. A heirloom glasshouse can still be a bad recommendation for a buyer who starts seeds in spring and overwinters a few pots, and a bargain kit can still be a bad recommendation for a buyer in a high-wind, heavy-snow site who needs a real anchored base. When a brand yellows early, racks without the optional base, ships with no vents, or is a white-label kit wearing an invented name, we say so directly. Every negative we publish is sourced and defensible, per our methodology.
Updates and corrections
We update guides when prices move, models are discontinued, glazing or warranty terms change, or a page is otherwise outdated. Greenhouse pricing and demand shift hard around the spring buying season, so money pages get re-verified before spring and season-extension pages get refreshed before fall. If a factual issue is reported, we correct it as quickly as possible and prefer updating the page over letting stale guidance linger.
Seasonal coverage
Greenhouse search peaks in late winter and spring, and again in a smaller fall season-extension bump. We publish and index the buying, cost, glazing, and base content before the spring peak, because you cannot rank a buying guide the month people are buying. That timing is our internal deadline, not a pitch. We do not run “buy before spring” urgency, no countdowns, no “don't miss the season”. The service is having the honest answer indexed when the buyer searches, not pressuring them once they arrive.
Structural and horticultural-loss content
A greenhouse is a structure that can fail in a storm, and a badly ventilated one can cook a season of plants in an afternoon. We treat wind-anchoring, snow-load, glass-safety, and overheating as structural and horticultural-loss topics, not content angles. Those pages are written conservatively, cite ASCE 7 and manufacturer engineering specs, carry no product links and no email capture, and never bend to stay commercially useful. They are not a substitute for the manufacturer manual or a licensed professional.
What independence means here
Independence does not mean having no commercial interests. It means not letting those interests dictate the verdict. Some links on this site earn a commission, and some premium-brand referrals earn a disclosed flat fee. No commission has ever moved a ranking, and if the mid-market greenhouse is the better option, that is the recommendation. The details live in our affiliate disclosure.
