In light deprivation greenhouses, ideal light levels vary depending on the crop being grown, as each plant has specific requirements for optimal growth. For instance, leafy greens like lettuce and spinach typically need 12 to 17 moles of light per square meter per day to grow optimally.
Fruit-bearing plants such as tomatoes and peppers, on the other hand, require higher light levels, usually between 25 to 35 moles per day, to support healthy fruit development. The purpose of light deprivation in these greenhouses is to control both the intensity and duration of light exposure, simulating shorter days to encourage flowering and fruiting at precise times.
