Artificial light for photosynthesis PPFD Gradient Form

Artificial light for photosynthesis "PPFD Gradient Form"

The light decay of LED lights is very serious with the distance. This gradient table can give us a reference to the PPFD data of led lights and a few centimeters away from our plants. According to our own planting environment, we can refer to the PPFD gradient table. Picking a grow light wattage that is right for my own space. For example: This light is a 110w plant growth light currently used in my garden. As can be seen in Figure 2, the ppfd in the center of the LED light is the highest, and gradually decreases around it. For example, if the distance between the LED light and the plant is 60cm, the PPFD Probably falls on 133-189. Take the Araceae plant as an example. If you think it is enough, hang the lamp 60cm away from the plant. If you want a higher PPFD, put the lamp closer to the plant, or replace it with a higher wattage LED lamp.

Special reminder, the general PPFD gradient table is based on the data tested by a single lamp. The light panel in Figure 1 that I use is in the 120-degree range. If you hang 2 LED quantum light panels like mine, the PPFD will be superimposed. of. Specifically, it is recommended that you test the PPFD data. May your plants and fruits and vegetables grow healthily!
