grow light

Indoor sun substitute

A grow light is an electric lamp designed to stimulate plant growth by emitting light in the spectrum plants need for photosynthesis.

Grow lights allow indoor cultivation where natural sunlight is insufficient—in basements, closets, or during winter months.

They're essential equipment for indoor gardening, cannabis cultivation, and starting seedlings: The seedlings are doing well under the grow lights.
