Question

How close should grow lights be to plants?

Answer

The distance of grow lights from plants depends on several factors such as type of light, wattage, plant species, and growth stage. Generally speaking, keep LED or CFL grow lights 6-12 inches away from seedlings and young plants, while moving them upwards by 3-4 inches every week until they reach their full height. HID lights usually need more space; place them around 18-24 inches away at first and adjust according to intensity levels. Monitor your plants regularly to ensure proper lighting conditions without burning leaves.
