The Best LED Lights for Weed

Using the best LED lights for weed is essential for your indoor grow. Investing in the best grow lights will help maximize bud quality and yields from your harvest.

Not all grow lights are created equal, and some are substantially better for growing cannabis. LED grow lights have become the most popular among growers, offering several benefits over traditional grow lights.

Although LEDs are among the best indoor grow lights available, there are so many of them that it can be difficult to distinguish between reliable brands and models and cheap, dubious ones. The best LED grow lights offer all the wavelengths required to produce big, beautiful buds. In this article, we’ll review the best LED lights for weed.

Why Use LED Grow Lights instead of HID Grow Lights?

LED lights produce more light and less heat than High-Intensity Discharge (HID) lights. Less heat in general combined with dimming options provide better control over light intensity and temperatures in your grow space.

Compared to HID lights, LEDs are more energy efficient. LEDs pull approximately 32 watts from the wall per square foot of coverage while HIDs pull around 40 watts. This allows for more light while using less energy. A full 4×4 foot grow tent can produce a quality harvest with an LED light as small as 400 watts.

The full light spectrum produced by LED lights have been shown to produce higher yields and quality than traditional lights.

Can Any LED light be used as grow light?

Your home might already have a few LED light fixtures. But can any LED be utilized as a plant grow light? Technically, yes, but the quality and yields will suffer.

Regular LEDs typically don’t produce enough light to support larger plants. Additionally, regular LEDs typically lack the ideal light color spectrums needed for proper growth.

Much of light produced by household white LEDs is not usable by plants. Utilizing a proper LED grow light with the right proportion of red, blue, and other wavelengths that plants prefer is ideal.

What Size LED Light is Needed for Growing?

The size of the LED grow light is determined by the size of your grow space. This is a better indicator than the number of plants being grown since even just one plant can usually be trained to fill an entire grow space.

The general recommendation is 32-50 watts per square foot of grow space. This is wattage being pulled from the wall. So a 4×4 foot tent would need a light that’s approximately 512 watts or you risk lower yields. In my experience, a light as small as 400 watts is fine for a 4×4, but never go below 100 watts per plant.

If you don’t plan to fill out your entire grow space, then using an LED grow light with a minimum of 100 watts per plant is sufficient. This should easily cover the two square feet minimum for one plant.
