What's going on my friends? How are you doing? Hope you are doing well today. Today I am going to shine a light on light. I think a lot of people who are indoor growers have a better understanding of light simply because you have to as an indoor

grower. You are replacing the sun, thus you kind of have to know what kind of light you're

shining on your plants. But for those of you who are outdoor

gardeners or haven't really experimented with indoors or hydroponics or anything

like that, but you do want to understand a bit more of the science behind how

plants use light.

Well then let's go ahead and get into it.

So the first thing to understand is that not all light is created equal.

Different types of light are going to drive and limit photosynthesis and change all sorts of different things about how a plant grows.

So when we talk about light in terms of gardening, what we really mean is something called PAR.

That would be photosynthetically active radiation.

So if you were to shine a light on a prism,

you would see it split into all the different colors of the rainbow.

So each of these colors is a wavelength, and that falls between somewhere between 400 nanometers and 735-ish nanometers, and that would go from the color

violet to the color red.

So that is the range of visible light that plants both need and use throughout different phases of their life.

Now plants are going to use different amounts of blue, yellow, orange, red light throughout their life.

Typically plants like the blue spectrum more when they're in vegetative growth,

when they're putting out their early shoots early shoots their vegetation they're preparing for

flowering and then as plants get closer towards setting fruit, flowering, going to seed, they

want red light, orange light and actually a bit shorter of a photo period and

that's what we're going to talk about next. Plants are able to tell time via light.
