If you’re planning on growing veggies, a full spectrum light with a color temperature in the blue range (5,000–7,000K) is recommended, and for fruits and flowers, the red range (3,500–4,500K) is the guiding light.

What color LED light is best for vegetative growth?

If you’ve noticed your yields are always below average, it might be the color of the lights you’ve been using. Different color lights have different effects on the plants they’re lighting. Depending on what you’re trying to accomplish or what stage your plants are currently in, you’ll need a specific color of LED grow light.

Blue Light: Blue lights with a Kelvin color temperature from 5000K to 6500K or wavelength in the 400–500 nanometer range are best for the vegetative stage of the grow cycle and for starting seeds indoors

Green Light :Green lights are commonly used during a plant’s dark cycle because it doesn’t trigger photosynthesis or photoperiod hormones. This means it does not disrupt the plant’s “night” cycle while allowing you to navigate the grow room to water, check timers, and spray nutrients or bug repellant. These are particularly useful if your crop requires short periods of daylight with long nights.

Red Light:Red lights from 2000K to 3000K and 640–680 nanometers are most important in the flowering stage. This range of light promotes stem growth and overall plant height because red light signals that there are no other plants above it so it can grow unimpeded. They also encourage fruit and chlorophyll production, so they can be used to extend the light cycle of long-day plants and vice-versa for short-day plants.

ECO Farm 700W/860W/1060W Waterproof Samsung 281B / 301B LED Grow Light With UV IR Separately Control

Key Features:

ECO Farm 700W/860W/1060W Waterproof Samsung 281B / 301B LED Grow Light With UV IR Separately Control Correct use of lamps with UV IR to ensure your plants grow better and get more trichome density and THC content . UV diodes increase the THC content of the plant and should only be used during the last two weeks of the flowering period, and may negatively affect the plant if used at other times of the year. What UV IR does: Increase the number of flowers, use it only at the beginning of flowering, stop using it as soon as buds start appearing. This requires that IR and UV must be controlled separately. IR and UV only need to be turned on separately when blooming, so we design IR and UV separately. IR is beneficial to plant flowering and fruiting, and UV can promote the formation of plant THC and CBD. Brightness can be adjusted from 0% to 100% to suit the needs of plants at different stages of sowing, vegetable and flowering, making planting easier for you. It comes with an external RJ 14 cable and allows you to install up to 200 fixtures per controller via a simple daisy chain. Easily dim and control a large number of lamps for you.

Best depends on your needs. A large, high-intensity light may be required to cover a large area. In a grow tent, small LED light fixtures may work just fine and generate far less heat. Therefore, you must consider light output, heat to be treated, height above plants, available color temperature, operating costs and fixture costs. There may not be one perfect light, but you can use small fluorescent or LED lights in smaller enclosed areas and larger, high-intensity lights in more open areas. All lights will grow plants well in the right conditions.
