Before Buying a 1000 Watt LED Grow Light

LED grow lights tend to vary widely in features like size, watts, power output, price, and so on. To choose the best 1000 Watt LED grow light, it is important to consider a lot of factors before making a purchase. Below are some of the essential considerations when shopping for a LED grow light.

Wattage/Light Output

By operating 10 hours a day on average, LED grow lights considerably increase electricity bills. That’s why you should look for an energy saving fixture. Pay attention to the total output in particular.

Higher outputs make up for the wattage loss. Compared to HID, LED lights provide more value. The powerful LED light options go up to 1000W. Such a grow light is capable of producing the light output equal to a 1200-Watt HPS system.

Coverage Area

All your plants need to receive enough light. In other words, that must be covered by the LED lighting system you use. That said, it is imperative to know the exact measurements of your growing area and choose the light accordingly.

As a general rule of thumb, you need about 32 Watts to cover 1 square foot for flowering. However, bear in mind that this requirement may vary depending on the plants.


Brightness, also called intensity, refers to how the lights shine or how deeply the light penetrates into a canopy. It has a significant impact on the overall health and potency of the plants.

It’s all about balance. You should use the light that can easily pierce your canopy. However,  make sure your light doesn’t shine so brightly, since it produces a lot of heat and can burn the leaves. On the other hand, the light with low intensity will not help your plants develop and grow.

Full Spectrum

When growing indoors, be sure to pick the LED grow light that provides both light spectra – the action spectrum and absorption spectrum. The former is highly efficient and critical for photosynthesis, while the latter is beneficial for nutrient absorption.

Obviously, you want your plants get everything needed for optimal growth. Both spectrum categories play important roles in the development and growth of marijuana plants. If your grow light lacks either category, your plants will experience a drastic drop in bud production and growth.

Photosynthetically Active Radiation (PAR)

PAR refers to the light spectrum that helps plants throughout photosynthesis. When choosing a LED grow light, avoid options that provide lots of ‘white light.’

Also, remember that there are many fake white lights on the market. Many manufacturers sell a blend of yellow and green light as white light.

Despite the fact that these light spectrums are beneficial for marijuana plants, they do not fit in the genuine PAR definition. While your plants will certainly benefit from these fake white lights, they won’t do anything advantageous for photosynthesis.

Heat Output

Traditional HPS/MH light systems emit too much heat, which could be harmful to your plants. In contrast, LED lights are designed in such a way to give off low heat. You are advised to pick the LED lights that emit suitable heat for cannabis plants.

Frequently Asked Questions About 1000 Watt Grow Lights

Why Choose 1000 Watt LED Grow Light?

The coverage area is one of the most important considerations when it comes to light wattage. 1000W grow lights allow you to cover a large area. This is where 1000W  LED grow lights come in handy.

These powerful lights are very suitable for marijuana plants which require high intensity. Instead of multiplying the length and the width of a canopy, you can now get the larger area by means of your light wattage. Thus, you will be able to get higher yields.

But it’s not all about power and coverage. Many people choose 1000 Watt LED grow lights because they are efficient, safe to operate, long-lasting, and extremely bright. In most cases, these grow lights produce optimum light for cannabis grow setups without being excessively superfluous.

How Far to Place the 1000 Watt LED Grow Lights from the Plants?

The hanging height, i.e. the distance between your plants and grow light, depends on several factors. Many manufacturers provide the recommended heights for their grow lights. So, your best bet is to follow the manufacturer’s recommendations.

Some manufacturers don’t provide any recommended height for their LED grow lights, though. If you’d like to go for 1000 Watt LED lights, then the ideal hanging height should be somewhere between 21 and 36 inches for the flowering stage, as well as anywhere from 36 to 46 inches for the vegetative stage.

How to Protect and Take Care of My LED Grow Light?

In general, LED grow lights have an incredibly long lifespan and are very efficient. The same holds true for 1000 Watt options.

Make sure your grow light is away from water so as to avoid short circuits and unwanted accidents. Likewise, make sure your grow light is not installed in a room with moisture, as water droplets may destroy or damage it severely.

You can keep your LED grow lights protected with the use of a power strip that comes with surge protection. The power stabilizers are also helpful. They can ensure accurate light and heat for the optimal growth of your plants.

Deciding on a 1000W LED Grow Light

Grow lights play an important role in indoor marijuana growing. But before purchasing a 1000 Watt grow light, it is critical to consider the quality and cost besides other features. You also want to use the light that would make your plants flourish and grow while saving you money in the long run.
