How We Research
Every guide on The Viral Garden starts with one question: will this product work for the person shopping for it? For greenhouses, that means your yard, your weather and what you want to grow.
Here is how we answer it.
1. We start with your yard and your climate
A small pop-up on a patio, a lean-to against a fence and a long tunnel on a garden bed each suit different people.
A greenhouse that works in a mild climate may struggle with hard winters or strong summer sun.
We check the footprint, height and door the maker lists. When your space or weather limits the choice, we say what to look for.
2. We compare specs and features
We look at floor size, height, frame material, cover type, door and window style, shelves and what comes in the box. For add-ons, we look at heater wattage and thermostat, fan size and airflow, panel thickness, plastic thickness and shelf size.
Makers describe their products in their own words, so we name the brand for every claim. We also note the warranty the maker lists.
3. We look at buyer feedback
We read what buyers report after using a product. We look for patterns, like frames that bend, covers that tear, zippers that stick and fans that run loud.
One angry review doesn't sink a product. A pattern does.
4. We score each product
Our score weighs specs, features and buyer feedback against what you're shopping for. A product that suits one reader may score lower in a guide written for another.
Scores spread out on purpose. A 10 is rare.
5. We keep pages up to date
Products change, and some disappear from stores. Many listings have look-alike versions with similar names, so we check each model and link only new units.
We skip unknown brands with no track record and any product with a known recall. When we update a guide, the "Updated on" date at the top changes with it.
What our picks are not
Our picks are research, not lab tests. We don't claim to have used every product we cover.
We quote the maker's numbers and name the maker. We give no medical advice and no engineering advice.
Light plastic greenhouses are not made for storms, so follow the maker's manual and local conditions. Electric heaters and fans need safe wiring, so use the maker's instructions and ask a licensed electrician about hookups.
