How to Use Grow Lights for Optimal Plant Growth
How to Use Grow Light?
To use a grow light effectively, you should first determine the type of grow light that is best for your plants.
There are four main types: incandescent, fluorescent, LED, and high-intensity discharge (HID).
For most residential and small-scale applications, full-spectrum LED grow lights are the recommended choice.
Once you have chosen a grow light, it should be placed within a foot of the plant to provide adequate lighting.
Plants should receive at least 12 to 14 hours of supplemental lighting per day.
The grow light should be left on for 8 to 10 hours a day to mimic natural sunlight exposure.
For indoor plants that do not receive any sunlight, up to 16 to 18 hours of light from a grow light may be necessary for proper growth.
By using a grow light correctly, you can improve nutrition, speed growth, accelerate flowering, and keep houseplants alive and healthy indoors.
