Gardeners growing under lights are starting to understand how important DLI is to their growing environment. References to K levels and distance from bulbs are long gone. These values are obsolete, especially when using LED lights to grow plants.
Now it is all about DLI, the Daily Light Integral. Get that right, and you can grow some great plants.
The problem is that DLI requires you to do some calculations, which nobody wants to do. That is why I developed a FREE DLI Calculator.

Key Takeaways
- Gardeners need to start using DLI to describe their lights.
- It is easy with the DLI Calculator
DLI Calculator
It is a simple spreadsheet program that does all the calculations for you. It is based on the Google Sheets platform.
Most Windows computers are configured to use Sheets. If you are on mobile, you will need to add the Google Sheets app to your device if you don’t already have it.
