1. Grow your starter beds
Campaign starts with $3,000, one gardener, 500 liters of water, compost and two planted beds. Press 1× to begin growing. Lettuce needs six growth hours and basil needs eight. Cloudy and rainy weather slows growth slightly.
Tap a bed to inspect moisture, soil and crop health. Harvest when the progress bar fills. Without automatic replanting, the bed stays empty until you buy the next seeds.
2. Keep water and soil healthy
Each gardener automatically waters three beds, starting from Bed 1, when moisture falls below 30%. The tank must contain at least 25 liters. Refill it in Supplies or water a bed manually.
Every harvest reduces soil fertility by 18 points. Apply one compost bag to restore it to 100%. Low soil fertility reduces harvest yield, while dry soil damages crop health and stops growth.
3. Plan for the weather
Weather follows a four-day cycle: clear skies, cloud cover, rain showers and a heatwave. Hot days use more water and harm crops unless ventilation is on. Ventilation costs $15 per day.
A rain collector adds 500 liters at the start of rainy days, up to the 2,000-liter tank limit. Automatic harvesting collects ready crops each hour; optional replanting for each bed pays seed costs automatically.
4. Sell your harvest or keep a promise
Harvested produce lasts 36 game hours. Sell it at the market, where prices change daily and reputation adds a small premium, or hold it for a buyer contract. Selling all stock also sells any crates you hoped to reserve.
A new contract is offered each day, with a fixed payment and 30 game hours to deliver. You can have two active contracts. Missing a deadline costs five reputation. Plan the crop and growing time before accepting.
5. Expand from a working business
Build up to six beds and develop tomatoes and strawberries. Each gardener waters three beds. New beds, crop development and infrastructure need investment; leave cash for seeds and the next daily costs.
Accounts shows a cash operating result: seeds and supplies count when purchased, while investment and rewards are separate. Claim six chapter rewards in Goals. Campaign closes after three consecutive nights below $0; sandbox starts with $14,000, optional funding and no forced closure.

Check the foundations.
- The water tank covers the next growing cycle.
- Gardeners can tend every planted bed.
- Ventilation is on during a heatwave.
- Harvested stock will sell or ship before spoiling.
- Enough cash remains for seeds and closing costs.
Your next move is in the game.
