Grow lights can range from $20 – $2000+. You should decide on a price range that you are thinking to spend on and consider it as a long term investment.

Note that some people think expensive items are of good quality but that is not the case with this product, sometime cheaper products is better than the costlier one.

Maintenance Cost

Before buying a grow light, check how often you need to replace its bulbs (LEDs) and the cost of replacements.

Changing the LED lights, when needed, are not expensive but you would be wise to know their costs and be sure of easy availability.

Size of the Grow Space

This is very important factor for choosing the grow light, the area of plantation.

You can’t just pick any light, first you need to calculate the area and buy the light with precise watts.

You won’t get a great crop if you either put less or more watts of light.

For example, find out watts (W) of light an area needed to properly grow plants in 1 square feet, and then calculate the area of plantation.

Use below equation to get the total watts needed for a growing area.

Area (in square feet)    x    Watts per square feet    =    total required watts

So suppose you have an area of 5 x 5 that is 25 square feet, we know that about 30-50 watts of light is sufficient to produce plants in one square foot, so use the above equation to calculate the amount of watts needed to cover the 100 sq. ft. plantation area. Note we assume 40w/sq. ft.

25 x 40 = 1000

You need 1000 wattage of lights to cover 5 x 5 plantation areas. If you follow this equation and put the precise lights, then you will get the optimum result from your led grow lights.

What are you growing (Style of grow)

This is yet another important factor you should consider while buying an LED light. Every plant is different in characteristics of size, height, and various aspects needed to grow properly.

Each plant needs various ranges of lights, you should first find out what type and how much light is needed for a plant to grow properly. The light source should match as much as possible the needs of the plant.

In that case, if you buy a light with low watts or with dissimilar bands or spectrum, then you may not get the desired output.

More information about LED Grow Lights

Look for the LED lights that support more bands so that can be utilized for growing various plants also look for the presence of UV (ultraviolet) and IR (Infrared) bands.

We did not find LEDs in the precise spectrum range that the plants need, so we must at least find LEDs which are the closest to the maximum in the curves.
