Garden Space Estimator (GTG Signature)

Estimate how much garden space you need to grow a meaningful share of your food—then layer in beds/containers, crop mix, water use, budget ROI, and sustainability impact. Includes a GTG Garden Capacity Score (0–100). Educational tool — not professional agronomic advice.
