Where do I need to place my grow light bulb?
The optimal location for grow light bulbs is above the plants, replicating natural sunshine. But don't simply leave it there, you will have to change location depending on how much heat each lamp generates. Plants should be at least 24 inches away from conventional grow lights. LED and fluorescent grow bulbs produce lower amounts of heat, so you'll need to set them 6-12 inches away from the plant.
