To use the calculator simply enter the PPFD, then the hours of light you are providing per day. The DLI will be calculated for you.
The PPFD User Guide tells you at what height to run each PRO GROW LED fixture on any given week of your grow / bloom cycle. When learning to use your new LED it is important to follow these recommendations. The correct fixture height above the plant canopy will ensure your plants aren’t getting too much light, too soon. Always start with reduced light, slowly increasing to full light output at the middle of the flowering period.
There are two ways to determine the PPFD of your LED light source.
Use a quality light meter:
To accurately measure PPFD, purchase a quality light meter that reads in PPFD. When using a PPFD meter, take multiple readings at the upper layer of leaves and branches of the plant canopy.
Use the PRO GROW PPFD User guide:
The PRO GROW PPFD user guide tells you the PPFD of each fixture at a certain distance. As the distance from LED to plant canopy decreases, the PPFD gets higher. Enter the PPFD figure that is recommended for each stage of growth and make sure that your LED is at the recommended height listed for the corresponding week.
PRO GROW range of LEDs utilise industry leading diodes, coupled with reliable electronics to deliver horticultural LED lighting solutions that outperform the competition in quality light output, end product yield and purchase price.
