Vent Pane Growhouse

Run a sunny glasshouse hour by hour. Open the roof vents, pull the shade, mist, water and heat to keep tomatoes, cucumbers, lettuce, peppers and seedlings comfortable through changing weather.

HOW IT PLAYS
Each season lasts a few simulated days, and every hour is one step. Run the clock, pause it, fast-forward, or step a single hour at a time while you decide what to do next.

Outside, the weather shifts from sunny spells to cloudy days, cold nights and heat waves. Inside, air temperature, humidity and soil moisture follow a simple energy and moisture balance, so every choice you make has a visible effect.

YOUR CONTROLS
- Roof vents with three positions
- Shade screen, heater, misting and watering toggles
- Hour-by-hour greenhouse climate simulation with sun, cloud, cold nights and heat waves

KEEP YOUR CROPS HAPPY
Five crops each have their own temperature, humidity and soil comfort ranges, plus survival limits. Heat, cold, drought and damp air slow growth or harm health. Damp, saturated air builds mould pressure that you must vent away.

PLAN YOUR BUDGET
The heater costs energy, and watering or misting cost water, both drawn from a limited season budget. Spend wisely to reach the harvest target.

TEN SEASONS
Ten seasons come with harvest targets and energy and water budgets, and each one is proven winnable. Reach the target to earn one to three stars and open the next season.
