Is white light good for marijuana cultivation?

In fact, Cannabis is same as most other plants respond well to white light. White light is a mixture of all colors. If you add blue, green, yellow and red together, you will get white.

And most of the LED grow light in the market are white light plus red and blue light. Some grow lights manufacturers choose to use blue or red diodes mainly because these colors or wavelengths are the most effective. That is, each photon emitted requires the least amount of electricity.

Although red and blue light can make plants grow, experts in the field say green light is also conducive to some processes of plant growth and flower production. Although green light may not be the main driver of photosynthesis, it contributes to other processes such as plant health and appearance.

It is important to remember that white light has different Kelvin. Kelvin is a range that classifies white light. Your average white light is about 3500K. Higher Kelvin (e.g. 6500k) produces cold blue and white light. Lower Kelvin (e.g. 2700k) produces warm red and white light. For plants growing, Generally, more white color is good for plant growing, less white color is good for plants flowering and harvest.

So Growers usually prefer to use more blue spectrum during the vegetarian period of cannabis plants. During flowering, cannabis plants need more red light to reach their full potential, 3500K is a good overall white spectrum, covering the whole plant life. Also you can use a 6500k spectrum during vegetarianism and then move to 3500K or 2700k during flowering.

In the end, white light has a great effect on cannabis plant growth. Because it contains a lot of green wavelengths, it results in stronger growth
