Greenhouse Cross-Section Simulator (2D)

This 2D simulator slices a growing greenhouse in half: sunlight of varying strength streams through a glass gable roof onto rows of potted plants below, warming the interior air past the outside temperature exactly as real glass traps heat. Switch between spring, summer and autumn to change the sun's intensity and the outside climate, crack the roof vent open to bleed off excess heat before the beds overheat, and water the soil to keep moisture high enough for seedlings to sprout, flower and fruit — watch the live interior-temperature, soil-moisture and growth readouts respond to every choice.
