Under blue LED lights, strawberries have higher biomass overall, produce more quickly, smaller leaves, and lower levels of anthocyanin and chlorophyll.
Under red Lights, strawberries have a slower, lower yield, less biomass, larger leaves, more anthocyanin, and more chlorophyll.
All in all, you would be better off having a higher blue ratio in your light spectrum if you want a bigger and faster harvest. However, the fruits would also require exposure to red light in order to boost anthocyanin levels and enhance chlorophyll production in the plants.
A full spectrum grow light would be the ideal lighting for strawberries. This is because it will guarantee that the plant receives every spectrum required for uniform and healthy growth.
