Best LED Grow Lights for Growing Marijuana at Home

In our previous article “What to Look for in LED Grow Lights for Growing Marijuana Indoors” we gave an overview on what LED growing lights are and what you should get for your home grow setup. But there are so many kinds of LED lights in the market today with different specifications and different technologies that you’ll need to do a great deal of research before buying if you want to get your money’s worth.

When shopping for LED lights, you may notice a significant price difference between similar products. This is not a mistake, good LED grow lights, especially those from established manufacturers, will be expensive. That doesn’t necessarily mean that the cheaper LEDs are fake or inferior, most of them are suitable for indoor growing of other plants, but not marijuana. 

While it’s nice to have the top-of-the-line LED growing lights, you don’t have to splurge on them if you are a casual grower. In most cases, you’ll be able to get a decent yield with mid-level LEDs, This is why in this list where we look at some of the best grow lights, we’ll also consider some of the cheaper ones since they are the most appropriate for certain smaller setups. 

How many watts do you need?

Most home growers in the US are only able to grow 4 to 6 plants for personal use so for this article, we’ll only look at LED lights that make sense for this kind of setup. These lights have to be fairly inexpensive since you’re not growing for profit, but still powerful enough to give you a decent yield. The LED lights that you get should also be capable of generating the right color temperature during the grow and bloom phases.

Wattage and PAR ratings

Wattage is a confusing topic when it comes to LED grow lights. Before LEDs became popular, lights were rated in watts which indicates the amount of power a bulb uses. Back in the days, bulbs, specifically HIDs, that used more power were typically brighter, but this is no longer the case with LEDs. When choosing LEDs for growing, it is better to choose based on light intensity which is measured in PAR levels expressed in µmols/m2/sec. Ideally, your plants should be getting a PAR level of 300 to 400 µmols/m2/sec during the vegetative phase and 750 µmols/m2/sec during the flowering phase.

However, consumers can’t seem to stop using wattage rating as the basis of a grow light’s performance which is why manufacturers and sellers still highlight wattage rating as a selling point even for modern LEDs. But for most LED products nowadays, the wattage rating indicates the equivalent light intensity in an HID bulb and while this will give you a good idea of how powerful a LED light is, you should still check its PPFD/PAR level rating.

The best LED grow lights for your home growing setup

Now that you’re already aware that wattage isn’t the only spec that you should be looking at, it might make it all the more confusing to know which LED grow light you should get. To help you decide, we rounded up the 5 of the most well-reviewed ones that will surely give you the most value out of your money.

Frequently Asked Questions

How many watts should I get for my grow light?

A 5′ x 5′ grow area will typically need 700 to 900 watts. However, keep in mind that the indicated wattage on most grow LEDs nowadays is a value approximately equivalent to the light intensity rating of an HID bulb.

Are LED lights good for growing marijuana?

LED lights are great for growing marijuana since they generate way less heat and consume less energy than their HID counterparts. However, they are also typically more expensive than HIDs but prices are steadily going down every year.

How much more expensive are LED lights compared to regular grow lights for growing marijuana?

LED lights are still generally more expensive than HIDs but prices are coming down. For comparison, the iPower 1000 Watt HPS MH Digital Dimmable Grow Light System Kit costs $205.83 while the VIPARSPECTRA Dimmable PAR700 700W Full Spectrum LED Grow Light is already at $309.77.

How long do LED grow lights last?

On average, LED grow lights are built to last around 50,000 hours or greater, which is 5 times more than an HID grow light.

Conclusion

When shopping for LED grow lights, you may frequently come across LED lights like HLG’s 600 Rspec Quantum board LED grow lights or Black Dog LED’s PhytoMAX-2 1000 which are worth hundreds of dollars more than the products on our list. These LED lights are worth every penny of their price and while they are very nice to have, it doesn’t make sense for every grower to buy one. As a home grower, you don’t want to spend more on equipment than what you’ll get to harvest, that would be splurging rather than investing. While these LED lights may not be adequate for commercial or craft marijuana growers, they are certainly an excellent option for the casual home grower.
