It's emmited by te sun and covers a range from 100nm to 400nm, which we can't see it in our human's eyes.
There are 3 types of UV light. UVA and UVB are important because they can pass the ozone layer. UVC can't reach Earth's surface.
Pros of UV
IR wavelength is longer than visible light(400-700m). lt's considered the light wavelength
beyond 700 nm.
Deeper penetration, heat radiation and the shade-avoidance response for plants,IR can:
Deep Red refers to 660nm-680nm, it is the most important spectrum for the flowering period
This range of light, around 660-680 nanometers, is crucial for promoting plant growth during the flowering and fruiting stages.
Pros of Deep Red
There are 3 types of UV light. UVA and UVB are important because they can pass the ozone layer. UVC can't reach Earth's surface.
Pros of UV
Inducing the production of secondary metabolites. such as flavonoids and anthocyanins, enhanced resistance to pests, stresses, and diseases.Produce more THC Deeper penetration, heat radiation and the shade-avoidance response for plants,IR can:
Increase the photosynthesis rate.Promote robust stem growth and proper node spacing.Stimulate flowering, shorter plant whole growing cycle.This range of light, around 660-680 nanometers, is crucial for promoting plant growth during the flowering and fruiting stages.
Pros of Deep Red
Booster of the flower buds.Promote plants to bloom and bear fruits, make flowers and fruits larger and stronger.Enhance the brightness of flower colors and fruit. make them look more stunning and taste good.
