6 Best LED Grow Lights For Herb Growing | How To Choose LED Lights

If you want to increase your yield and spend less on power bills, then a LED grow light is the way to go. They use 75% less energy in comparison with typical lights and will not overheat as well. You can continue growing without worrying about wasting precious energy and lower yields for herb farmers like you!

Many herb growers know that traditional grow lights can be inefficient. You may not have thought of it, but the type and color spectrum they shoot at your plants are also key factors in determining how well they photosynthesize.  What many don’t realize though – even when using LEDs as a main light source, and is just as important: only certain wavelengths should go towards enhancing growth (i.e., blue or red) while others might harm more than help if too much radiation gets absorbed by leaves.

Advantages of using LED Lights To Grow Herbs

LED lights are a great option for growing marijuana because they last much longer than traditional lighting methods, which can be expensive in the long run. They also produce less heat and require less power to operate--two major advantages when you're running multiple grows at once!


The use of LED lights is revolutionizing how we produce and consume electricity. They’re not only more cost-effective than High-Intensity Discharge (HID) lamps, but they last 50-60 times as long! For example, you can expect between 50-60 thousand hours worth of usage from an LED light compared to 2k - 3ks with a standard incandescent bulb!

 That means you can spend less on replacement costs for your lighting system - which will ultimately save money in the long run too. The benefits don't stop there: with an led light source there's no need to worry about burning out filaments because these units do not include them.

Space and Heat

Growers who use LED lights can enjoy a range of benefits over their HID counterparts. For one, they emit light faster, no need to warm up, and with less heat which helps to keep your grow room cool - reducing the risk for fire significantly! LEDs also take up much less space than HID systems; this means more growing area per watt using an entire panel instead of just two thirds as many watts from each fixture like in some cases when running dual fixtures at once.

Light Efficiency

The reason LED lights consume less than HID lamps, and can even produce more light per watt compared to other forms of lighting like Compact Fluorescent Lamps (CFL), is because they use lenses to focus the rays instead. This means there's no need for reflectors which add yet another element that needs maintenance: keeping them clean!

With an internal focusing system like these things have, you don't even really need anything besides electricity itself since it takes care of all responsibilities involved with turning electric currents into radiant energy - it adds up quickly to how easy to use LEDs are.

Disadvantages of using LED Lights

As amazing as the benefits sound though there still may exist some cons worth mentioning too. LEDs don't offer quite as intense of light compared with other options so this could lead your plants' leaves being harder (or even impossible)to grow properly depending on what kind/color LED setup system was chosen; another downside includes needing special 100% lenses.

LEDs (especially high-powered ones) require a delicate touch when it comes to power management and heat. You need precise control over the current for these LEDs because any mistake could cause them damage or harm quickly.

On top of that, their upfront costs are usually higher than those for HIDs so there can be some initial financial setback in using such lighting equipment - but once you factor things like longer life spans into account then LED lights to start looking more reasonable again!

How To Choose The Best LED Light For You

LED grow lights have revolutionized the way we garden. But what if you don't know where to start? You’ve probably read dozens of LED light reviews, and are no closer to making your choice between quality products for both herbs as well as electricity use - which is frustrating! The first step should be determining whether or not these new technologies will work with YOUR growing needs.

LED lights are so popular it's a wonder that anyone can make up their mind about which type is best for them. You have to first eliminate the useless LED bulbs, then decide on quality instead of price or wattage and size, and this task might take some time if you're looking into grow lamps.

There's a lot to consider when purchasing lights: what type of environment do I want my plants in? How much light am I trying to produce per square foot (or metrics like that)? And which color spectrum are most important - reds have been found by some studies to show an increase in potency while green produces better photosynthesis. Here are the main factors to consider:

Real Wattage And Theoretical Wattage

You may have noticed that most LED lights have two different wattage figures. One is the potential, which measures how much power light could run at if all of its chips were working perfectly and ran constantly on full blast; this can be 600 or more watts for some high-end models with 200 3w LEDs per square inch (or m2).

The other figure you'll come across is what each unit in an array consumes when operating under standard real conditions. They're usually about halfway between these upper limits so don’t worry too much! For example, a 100 point hand desk lamp might read 90 W peak but only 50/60 W average instead making them last about three times as long with little decrease in brightness.

Light Emission

The majority of these fixtures use red and blue light, but some white LEDs, as well as infrared or ultra-violet ones, can also be found in this mix - it's called full-spectrum lighting because its color temperature provides enough warmth needed by younger seedlings while producing bright sunlight necessary later on when growing taller vegetation such cannabis grown indoors.

The indoor cannabis industry is trending toward white LED grow lights. This change in light fixtures comes as a result of many growers' personal preference for sun-like illumination, which some say provides more natural sunlight than traditional high pressured sodium (HPS) bulbs do and allows them greater control over photosynthesis rates through adjustment.

Light Intensity

For LED lights used for growing weed, the most widely used measure of intensity is PAR. It stands for Photosynthetically Active Radiation and measures how much light in the wavelengths plants use to photosynthesize. High values mean a powerful intensity in the centre of the illuminated area but not around the edges as they will be dimmer.


The coverage area of lighting refers to how much light can reach the plants in a given space. For flowering stage growth, you will need more intense lights and less than usual for vegging because it is when your plant needs the most energy output from its chlorophyll-rich leaves--the ones that help convert sunlight into sugars used by all parts within the canopy (including stem).

When choosing which type or color(s) would be best suited depending on specific goals like bloom time vs vegetative weight gain rate; keep an eye out about if this matches up with what kind of requirements are set forth by where/how these fixtures will eventually end up being installed.
