Avoid Light Stress by Keeping
LEDs the Right Distance Away
Keep your LED grow light the perfect distance away from cannabis plants to maximize plant growth, yields, and bud quality. But how do you know the best distance?
Recommendation: Follow the manufacturer's recommended distance or contact the LED company directly for guidance. I've been pleasantly surprised to find that most LED companies answer questions about how to best use their LED grow light. If you still can't find any
information about your specific model, here's a set of basic guidelines to follow.
- Small LEDs around 100-200W are usually kept about 12-18" away.
- Medium LEDs like 200-300W are usually kept about 18-24" away.
- Big LEDs from 300-600W are usually kept about 24" or more away.
These are good general rules, but even more important is to pay attention to your cannabis plants and see
what they “tell” you.
In the next section, you’ll learn how to tell whether your LED grow lights are too close or too far away from your cannabis based on how the plants look.
Avoid stressing your cannabis plants with too-close LEDs!
