How Does Photosynthesis Work With LED?


If you are unfamiliar with what photosynthesis is then it’s basically what enables plants to eat, plants require light to eat or they will starve and die even with a full nutrient compliment to their root zone. 

Photosynthesis converts light into chemical energy within the plant which then gives the plant fuel to perform certain activities, much like solar panels generating electricity to allow you to perform certain activities within the household.

Think of your leafs as your plants solar panels, the more leafs it has the more it can photosynthesize and therefore the more food it can absorb

Blue and Red LED's

Why do led grow lights use mainly blue and red led’s for plant growth we hear you ask?

The main chlorophyll absorption peaks for plants are targetted most efficienty by using blue and red leds of specific wavelengths and bandwidths.

So inducing photosynthesis via led is extremely efficient compared to traditional grow lights that throw either red, blue or every colour at your plants.  With leds we target the exact wavelengths to correlate with the Chlorophyll A and B absorption peak areas blue 445nm - 475nm and red 615nm – 670nm.

Chlorophyll A & B

Chlorophyll is a green pigment found in plants and is essential to photosynthesis, there are many different types of chlorophyll but the ones we are interested in are chlorophyll  A (Universally used) and chlorophyll B (Used  by Plants). See the chart below for the chlorophyll absorption peak areas:
