The Kelvin colour scale of led lights for indoor plants

Light is important for the growth and development of the plant. Additionally, light exposure can be used to help your plants from their growth phase into their flowering phase. This is because a plant starts preparing itself for the flowering phase when it gets less hours of light a day. As such, a growing plant needs more hours of light exposure than a plant in its flowering phase. If you’re growing indoors, you can black out the plant to regulate the amount of light it receives. Led light is most commonly used because it dissipates less heat and the ideal temperature ( +/- 24 degrees) is easier to control and maintain.

Colours

White lamps can emit many different colours. These colours have a certain effect on your plants. The colour your led-lamp emits is CCT (Correlated Color Temperature). Colour temperature is expressed in Kelvin or K. Depending on the Kelvin value your lamp will have a certain colour. A different colour also means a different effect. Generally speaking, you can distinguish the following:

PAR

The amount of usable light for plants is expressed as a frequency value within the electromagnetic (light) spectrum. This spectrum runs from UV light to infrared light. The light your plants have available for photosynthesis is called PAR (Photosynthetic Active Radiation). PAR falls within a frequency band of 400-720 nanometers.
