About Garden by the Numbers

Garden by the Numbers helps home gardeners buy the right size and type of equipment the first time. We focus on a narrow subject: raised beds, grow lights, seed starting, watering and season extension.

What makes us different

Most buying decisions in the garden can be worked out. How much soil does a bed take? How much light do tomatoes need? Which mat fits a tray? We answer questions like these with calculators, published specs and extension publications.

What we don't do

We don't claim to have tested a product unless we actually have, and we'd say so clearly on the page. Our current guides are research-based. We can tell you what fits and what the numbers say, but we can't tell you how a product holds up after years outdoors.
