You may have heard about olor temperture. Cold white (5000k, 6000k, 6500k) looks blue. Warm white (2000k 3000k 3500k) looks yellow. Usually manufacturer of led grow lights will add leds of those temperature to their grow lights. Do plants really need blue light for vegetive stages and red (warm) light for flowering stages? In this article, we will tell you.
Used we use MH and HPS Grow Light. MH has more blue light which plants need to prevent stretching. HPS has more yellow light, which is important for plants' rapid growth during flowering. Both are designed for plants growth, but each is more suitable for a certain stage of plants growth than the other. LED grow lights combine them, designed led grow lights with red and blue leds, full spectrum, ideal for indoor plants growth.
Blue Light
Plants photosynthesize nutrients for growth using green substance in their cells called chorophyll. Most tyoe of chorophyll can use the blue light more efficiently than the red light. Most blue light end causes the celles to be enlongated, changing the growth of plants and the plants size.
Red Light
The pigment phytochrome mediates flowering of plants with a photoperiodic flowering response. Plants are sensitive to red light. Red light can inhibit flowering of short day plants and promote flowering of some longday plants. The additional IR to red light is effective to stimulating flowering.
Balance the Blue and Red Light
The best is to balance the red and blue light. A balanced light spectrum sunlike is slightly high in blue and with some red. It's a good mix and to render the colors ture to what they would be under natural sunlight.
