Criteria: What to Look for in the Best LED Lights for Growing that Save Energy

Wavelengths and Spectrums

Before you make a final purchase, make sure that you take a look at the wavelengths and spectrum the LED lights offer. This crucial piece of information helps you determine whether or not these LED grow lights are appropriate for the type of plants you’re looking to help flourish.

Coverage Needs

The other factor to consider is the coverage needs of your specific plans. Consider the PAR output. Is it high enough for all of your plants to continue growing? Do the lights cover the space you need and are they intense enough for healthy plants to continue thriving? Remember that IR and UV wavelengths provide that extra protection and allow for extra growth, so make sure to look out for those as well.

Styles

As you can see in the list above, there are different styles for LED grow lights. You can go for chips on a board or those gooseneck styles that allow for a lot of flexibility. Make sure you pick something that works both for your plants and for the space they live in.

Extra Features

Extra features are super helpful, especially when you’re not always at home to care for your plans. For example, having an automatic on-and-off timer takes the stress away and lets you enjoy nights away from home with more calm. Being able to dim your lights is another great feature that gives you complete control over the intensity of the lights. Although some of these awesome features are something you can go without, they definitely add a lot to your growing experience and are worth considering.
