CFL

CFL grow lights come in many different shapes and sizes, they produce a great spectrum for growing cannabis and can be used in tiny spaces where no other grow light would fit. CFL bulbs can be kept mere inches away from your plants without burning them.

Fluorescents are popular because they make efficient and pleasant lighting similar to daylight, and also work great for herb gardens and other types of low-key indoor gardening without using a lot of electricity or generating too much heat.
