In my years of being a grower, I found the ViparSpectra KS3000 LED Grow Light to be the best. It has excellent heat dissipation, it’s waterproof, and it is a full-spectrum light, which simply means that its glow is similar to that of the natural sun. I’ll discuss more on why I chose this as the best LED light in the latter part of this guide.

For now, let me briefly discuss what makes LED grow lights good and effective.

What You Have to Consider When Choosing LED Grow Lights

Not all LED grow lights are made equally. There are grow light brands that purposely make lights for warmth and heat; there are those designed for its dimming and light intensity, while there are other lights that consider cool features as a crucial factor, and so on.

I’m going to end that debate by laying out the best and most important considerations you need to factor in when choosing the LED grow light for your cannabis plants.

Type of Grow Light

If you think that there’s only one type of grow light (LED grow light), think again.

In fact, there are three (3) types of indoor grow lights: LED, HID, and Fluorescent. According to experts, to ensure the proper growth of your cannabis plants, you must consider and factor in the type of light you put under.

Let me discuss the differences between these types of grow lights.

Light-Emitting Diode (LED)

Light-emitting diodes or LEDs are the newest, most modern, but the hottest and most sought-after type of grow lights. These lights emit 90% or more light without putting in too much heat.

It has high light intensity without burning the plant canopy and worrying about it.

High-Intensity Discharge (HID)

HID or high-intensity discharge, is the classical or traditional artificial lighting used by growers and cultivators. These grow lights are considered “the best” before LED because of their high light intensity.

However, unlike LED, the heat emitted by HID is also extreme. Therefore, you’ll need other equipment for heat dissipation, such as cooling fans, AC units, or a cooling system to supplement it.

HIDs are also categorized into two (2) different types: high-pressure sodium (HPS) and metal halide (MH)

CFLs or Fluorescent

Last but most definitely not least are Compact Fluorescent Lamps or CFLs. CFLs or fluorescent lamps are options taken by growers of indoor plants because they are cheap, inexpensive, and have the necessary warm white light spectrum cannabis plants need to mature and grow.

Different plants can benefit from it as they put off less heat than HID, but they’re also a bit dimmer and subtler than them.

Light Spectrum

Another factor you want to consider would be the light spectrum. Marijuana plants require different spectrums in various growth stages; therefore, you need to ensure that the light you’re using fits the particular stage perfectly.

Here’s a quick guide to the light spectrum needed by cannabis per growth stage of their life cycle:

• Seedling Stage —white light (30%), blue light (30), red light (15%)
• Vegetative Stage — blue spectrum
• Flowering Stage — red and white spectrum

Heat Emission

Other than the light spectrum emitted by grow lights, marijuana plants also need heat that differs from one particular stage to another. Too much heat emitted can be bad for both the texture and quality of the plant; not putting in too much heat, however, is as bad.

So, you need to make sure that the distance and temperature of your grow lights are on point.

Maintenance

You don’t want to buy LED grow lights monthly, right? I don’t know about you, but in my opinion, I try to maximize my grow tent, grow space, and grow lights so that they can last long without me having to replace them.

The most important part about maintaining grow lights would be by looking at their power consumption. Power or electricity is the one that controls the voltage and wattage of the light, and therefore, it’s just right to make the necessary considerations about it.

Plant Growth

As I mentioned above, different stages in the plant’s life cycle require different types of lights. Therefore, you also need to take into consideration how fast or slow the growth and maturity of your plants will be.

TIP: You don’t necessarily have to have different types of LED lights and grow lights inside your grow space. Altering the distance as well as the light intensity will be enough to accommodate the light requirement of your cannabis plants.

Price

Let’s not be hypocrites here — the price or the cost is probably the factor that we all look into. And while securing yourself a cheap LED grow light is good, it might be drastically damaging to the conditions of your greens.

Cheap LED grow lights won’t have all the features you’re looking for, not to mention the quality of light and efficiency they can give you. So, don’t be too frugal when it comes to choosing your grow lights.

Today is your lucky day, though; why? — Because I’ll be listing 10 of the best LED grow lights you can use for better energy consumption, higher power, and more efficient usage without the hefty price tag!
