How Many LED Grow Lights Should I Need?

I have a garden. I wonder how many LED grow lights do I need?

It depends on the amount of plants you have. When figuring out how many lights you’ll need, there are some terms you’ll need to know:

Plant Coverage: The amount of light that a lighting will provide for each plant.

Light Intensity: The amount of light required for optimum plant growth, measured in PAR for LED grow lights.

Here are some steps that can help you figure out how many LED grow lights you should have for your crops.

Examine the PAR Requirements of Your Plants

Some plants require a higher PAR value for healthy growth, while others require fewer. Leafy greens, for instance, demand a PAR value of around 200, while blooming and fruiting plants like a PAR value between 400 and 500. To be certain exactly the amount of light for your healthy plants, you can measure PAR with a PAR meter.

Measure the Plant Coverage

Consider the size of your plants, including their present and anticipated sizes. Measure the perfect area that plants need to grow to their full height. Next, figure out how much space you’ll need to grow your plants indoors.

Choose a Grow Light Depending on the Intensity and Coverage

Grow lights offer measurements of their light output as well as the area they can cover when positioned at a specific height. As a rule of thumb, 32 to 50 watts of LED grow light per square foot is ideal.
