A: Full spectrum LED grow lights are usually the best choice. They give plants all the light colors they need and are energy efficient.

A: It depends on your grow space. A general rule is 30-50 watts of actual power per square foot for good growth.
Q: Do I need a special light for flowering?
A: While full spectrum lights work for all stages, some growers use lights with more red light during flowering to help buds grow bigger.
Q: Can I use regular household lights?
A: No, regular household lights don’t have the right spectrum or intensity for growing cannabis. You need grow lights.
Q: How close should my grow light be to my plants?

A: If the light fixture is too hot to touch comfortably, it might be too hot. Also, watch for plants showing signs of heat stress.
Q: Can I use lights for more than one plant?
