Using LED grow lights year-round for continuous greenhouse crop production is not typically recommended. Instead, it is advisable to maximize natural sunlight whenever possible, supplementing it during specific periods when natural light is insufficient. This is particularly important during the winter months when light levels are significantly lower than in the summer. Additionally, early mornings and late afternoons often experience shadowing or fog, reducing light availability. The most effective approach is to connect the LED lights to a photosensor, setting the target light level required throughout the year. This setup allows the LEDs to adjust their intensity automatically, ensuring the optimal DLI level is maintained consistently.
