What is daily light integral?
Daily Light Integral (DLI) is the amount of light particles, or photosynthetically active radiation (PAR), received by an area in one day. DLI will affect your plant growth and development. It is something you should consider when growing your own crops, especially when using grow lights (or a greenhouse setting). This will ensure that whatever crops you are growing aren’t getting to little, or to much, light. To measure the DIL in your area you will need a horticulture light meter. This will allow you to log light readings over a 24 hour time frame. You can then adjust the light accordingly. Below is a DLI calculator to use.
