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.
Ahmed runs Garden by the Numbers. A developer and math teacher who turns gardening questions into clear numbers, simple formulas and free calculators.
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.
