Important indoor lighting accessories
Ballast - if you connect a fluorescent lamp to a high voltage power source, it is likely to increase it power draw rapidly. You will therefore need a ballast to regulate the current flow and voltage to start fluorescent lamps. However, if you are using the led technology, you will not require ballast.
Reflectors -grow light reflectors are useful when dealing with seedlings and small plants. They redirect light back to the plant. This ensures increased yields per unit area
Hangers - they provide support where hooks are too weak to support the light. They also provide space for adjustments as the plant grows
