Promotes Flowering and Fruiting: Red light (600-700 nm) stimulates the production of phytochromes, which trigger flowering and fruit development. It’s critical for plants transitioning from vegetative to reproductive stages.

Enhances Fruit Size and Quality: Red light encourages larger, more robust fruits by supporting carbohydrate accumulation and improving nutrient allocation to reproductive tissues.

Accelerates Maturation: Exposure to red light speeds up the ripening process, helping plants complete their growth cycle more efficiently, which is ideal for finishing stages.
 

Boosts Photosynthesis Efficiency: Red light is highly absorbed by chlorophyll, maximizing energy production for fruit development and seed formation.

Improves Yield: By focusing energy on reproductive growth, red-dominant light 
increases the quantity and weight of harvestable fruits or flowers.

Encourages Pigment Development: Red light enhances the production of anthocyanins and other pigments, improving the color and marketability of fruits and flowers.
