How much to grow to feed your family
Most preppers buy seeds and gear but never answer the real question: how much do you actually need to grow and store to feed your household for months, not meals? Enter your people and your target, and get the plant counts, the space, the storage plan, and an honest gap analysis of where your calories, protein, and fiber fall short.
To feed 4 people for 6 months, grow about 8,166 plants across 12 storable staples in roughly 7,876 sq ft — about 7,925 lb of food worth $21,579 at the store.

How the numbers work
The plan is sized to your months of calories, then checked against USDA nutrition for protein and fiber. Every number comes from the same tested engine behind our garden planner — plant counts, yields, and space — so the estimate here and the real plan you build never disagree. It is an honest planning tool, not a survival guarantee: your climate, soil, and skill move the real yield.
