Seed sources, budget & costs

Choose available sources; budget caps the initial planting, not reinvestment. Crafted/found/bartered seeds are zero cash cost, not unlimited stock.

Machines, aging & seed recovery
Aging quality (Keg products)

Queues include machine and cask time. Zero means enough parallel machines, never instant goods. In-progress products stay inventory, not sales. Seed recovery assumes separate Seed Makers can finish the reserved inputs that day; results are an expected seed-yield scenario.

Summer Spangle requires new seeds after each harvest when you replant.

In a 27-day growing window, one tile gives 3 harvests and 270g revenue. Deducting 150g in seeds leaves 120g net profit, or 4.44g per growth day. This example uses normal quality, no profession, no fertilizer cost and immediate replanting.

Growth acceleration & last planting day

Outdoors, planting by the last viable day allows a harvest on day 28. A crop taking a full season needs a longer window. Season-free areas do not have a seasonal planting deadline. Repeat-harvest intervals stay unchanged.
