Improve
Crop Canopy

The top leaves of the crop canopy capture the most light, shading lower leaves. The air at the top of the canopy is also drier, which causes faster water loss in these leaves. To conserve water, WEST plants will have more vertical, paler green top leaves (right) that allow light to reach leaves lower in the canopy where it is more humid. The higher humidity limits water loss to the atmosphere while maintaining photosynthesis.
