The effect of light on chlorophyll synthesis of plants is that plants cultured in blue light generally have the characteristics of sunny plants, while plants cultured in red light are similar to shade plants. Red light is not only beneficial to the synthesis of plant carbohydrates, but also can accelerate the development of diurnal plants. On the contrary, blue-violet light accelerates the development of diurnal plants and promotes the synthesis of protein and organic acids, while short-wave blue-violet light and ultraviolet light can inhibit internode elongation and promote the growth of multi-lateral branches and buds. Light of 400-520nm (blue) and 6 10-720nm (red) contributed the most to photosynthesis. The absorption rate of plant pigment to 520-6 10nm (green) light is very low.
Based on the above information, you only need to buy ordinary blue tubes and red tubes when choosing aquatic plants. The color of professional aquarium lamp is pink, because it mixes blue light and red light. Therefore, when choosing aquarium lights, blue-white light is better than blue-white light, and blue-white light should be chosen.
