grow lights

Artificial plant sun

Grow lights are artificial light sources designed to stimulate plant growth, typically by emitting wavelengths similar to sunlight.

They're essential for indoor gardening, commercial greenhouses, and cannabis cultivation where natural light is insufficient: The seedlings need about sixteen hours under the grow lights.

LED grow lights have largely replaced older fluorescent and high-pressure sodium types.
