Economics of seed to table

The earlier you enter the cycle, the more upside you capture.

Food from the store is fast. Seedlings save time. Seeds create the largest grocery-equivalent value multiple when timing, watering, and succession planting are managed well.

cart

Buy grocery produce

The fastest path to food, but there is no production upside. You pay the full grocery-equivalent value every time.

plug

Buy seedlings

Skips two to six weeks of early risk, but you pay a large markup for that time savings.

seed

Start from seed

The highest ROI path, but it requires timing, germination, watering, transplant planning, and succession planting.

Yield assumptions

Crop	Grocery-equivalent output	Why this is reasonable
Lettuce	1 plant ~= 1 grocery head	Leaf lettuce reaches roughly 6-12 oz at maximum size in 50-60 days, depending on type.
Basil	1 plant ~= 10 grocery clamshells over a season	Basil can be harvested repeatedly; cutting above leaf pairs produces new growth and keeps plants productive.
Cherry tomato	1 plant ~= 10 lb tomatoes = sixteen 10 oz grocery packs	UMD Extension says tomato plants can yield 10-15 lb or more per plant, often for cherry tomatoes.
Cucumber	1 plant ~= 10 cucumbers	Recent garden yield guidance commonly places healthy cucumber plants in the 15-30 cucumber/plant range; 10 is conservative.

Where SteelThumb fits

Capture more seed-stage upside without adding another memory chore.

SeedPort captures the seed-stage ROI without asking families to constantly remember what needs to start next. Tendril protects the growth-stage investment by reducing missed watering, stale observations, and crop waste.
