How far should LED grow lights be from plants?
For seedlings, LED grow lights should typically be installed between 24-36 inches above the plant canopy – however, this depends on the wattage (wattage) of the light source. Place LED grow lights furthest away from seedlings (~36 inches) – this keeps heat and light levels low and helps prevent seedlings from drying out. Once the roots are established and budding begins, the lights can be moved closer (usually within the first 2-3 weeks).LED grow lights should be 12-24 inches from the top of the canopy during the plant growth stage. At this stage, photosynthesis requires more light, so the light source should be located near the plant.The need for bright light decreases as the plant enters the flowering stage. The top leaves of the canopy should be 18-24 inches from the light source to produce blooms. It is at this stage that the plant increases in height and bears fruit. Depending on the light and how you want your crops to grow, you don’t have to change the height of the light during bloom, especially if you don’t want tall plants.08/04/2022 Tags: Full Spectrum Light Panel, High Output LED Grow Lights, led grow light kits
