‌Choosing a spectrum suitable for cannabis growth requires considering the effects of spectral components on different stages of cannabis growth. ‌

The effects of spectral components on cannabis growth ‌

Blue light‌: During the growth stage of the plant, a grow light with a higher proportion of blue light helps keep the cannabis plant short and strong, with healthy large leaves. ‌

Red light‌: During the flowering stage, a grow light with a higher proportion of red light can encourage the plant to grow taller and promote budding. 

Plants enter the flowering stage faster under red light than under blue light. ‌

Yellow light‌: Although the specific effects of yellow light on cannabis growth are not detailed, yellow light is generally considered to be one of the spectral components that are beneficial to plant growth. ‌

Choosing the right spectral components ‌

Growth stage‌: Choosing a grow light with a higher proportion of blue light can promote dwarfing and healthy growth of cannabis plants. ‌Flowering stage‌: Choosing a grow light with a higher proportion of red light can encourage the plant to grow taller and promote budding, speeding up the flowering process. ‌Specific brand and model recommendation ‌Although the specific brand and model are not directly mentioned, you can choose those LED grow lights that are specifically designed for plant growth. 

LED lights are becoming the preferred choice for cannabis growers due to their high efficiency and long life. Choosing LED lights with appropriate photosynthetically active radiation (PAR) and light intensity (ppfd) can ensure that cannabis plants receive the best lighting effects.
