The led grow lights market is growing daily due to the high demand by farmers. The importance of led lights for plants or crops is to supply sunlight for maximum growth, but you only need a LED growing light if you have an indoor garden, greenhouse, or grow room (tent). If you are planting outdoor, the natural sunshine is enough to supply your plant with the right amount of photosynthesis required. Therefore, this article is only of relative importance for those who plant indoors, unless you want to learn about what’s growing led light.

Hence, it is substantial to let you know that grow lights come in watt capacity, and choosing an appropriate watt capacity for a specific coverage area will make your plant do better. For instance, 1000w led grow lights are more powerful than 600 watts if you are thinking of covering 5 x 5 feet. Some people have a misconception that a thousand-watt led grow light can only cover four by 4 feet.

Our point, there is no difference between the two feet’ size. You can use it either for 4 x 4 or 5 by 5 when choosing a high-quality one. But how do you know the good ones when there are lots of fake products out there. This is why we are here to help you through this discussion. We have emphasized the most relevant aspects so you won’t get lost, and our buying guide is lucid on the features to check for you to make a wise decision. We are starting with the comparison, followed by other areas of concern before the review section.

Why choose a 1000w led grow light?

In reality, you know, indoor garden, hydroponic, tent, grow room, etc., sizes vary. This, however, determines the performance of a particular grow light. The bigger the coverage area, the higher watt (W) capacity led lights you’ll need. Otherwise, you have to buy more than one unit for a particular space installation.

Always remember that your crops will do fine and better when a burst of adequate sunshine is coming on them, and their yielding may supersede your calculation. Therefore, a 1000w capacity led light may save you more space and cost than buying 2-separate units that have 600w rated if you’re to add sunshine in a 3 x 3 ft.

More so, the number of pieces you may need for a particular coverage area depends on the size. The table below will be helpful, knowing the exact quantity, but it might not be feasible in some enclosures.

Types of Grow Light 

Apart from led lights for the plant, other types are available, and it is wise to know them if you want to change your mind about buying led lights. All indoor grow lights fall into these three categories:

  • LED (light-emitting diodes): It is the most expensive of all types but more efficient. It lasts longer and consumes lesser energy as regards fluorescent and HID lights. With this model, you have a different color spectrum which intensity can be dim depending if the one you can do. It does not produce heat that can harm plants but have side effect when to human eyes. Therefore, people need to wear protection when entering planting rooms that have led lights. 
  • High-density diodes (HID): These are more powerful than fluorescent and are commonly used among professional farmers commercially. The HID models produce more heat and thus advise to be placed a farther distance from your plants to avoid killing them.
  • Fluorescents light: This can supply light to indoor plants but may not be as effective as LED or HPS, but still better than incandescent bulbs. To use a fluorescent, you’ll need a stand to place them, and also, the light needs ballast for current regulation.

How To Pick The Best 1000w Grow Led Light 

Grow lights are of different quality, making one product differ from the next. To avoid the wrong choice while buying the best 1000w led grow lights, the following features are worthy of note:

  • Coverage area: You need to consider the size of the enclosed space to use the grow lights before purchasing. Grow lights have maxima coverage areas to work best if you choose a product of a lesser capacity to your plant growing section. Your plants may receive a partial lightening, which can affect their performance unless you want to invest in more than one product. To overcome this challenge. Measure the grow room size and choose corresponding units that can effectively release artificial sunshine into it. 
  • Spectrum: A grow-led light with a red and blue spectrum is a reasonable deal for plants of any kind to do well. But if your grow light can provide infrared, ultraviolet, IR, or UV light, that means a more spectrum option to choose for plants growing.  
  • Energy consumption: An excellent 1000w energy-rated grow led light should be able to run for 12hours without consuming much power. Since you’ll want it to work for hours, it is appropriate to choose an energy-efficient product. Getting a unit of this rating will serve you a higher cost of electricity bills. So how do you know which is the best energy-rated product to choose? Any product whose output is below 300 watts is considered a bit low. Therefore, an upward value of, let’s say, 350w, 450w, 1000w, and above are a better choice to cut down electric tariffs.   
  • Light Adjustment: Too much light shining on your plants all the time can affect them. Moreover, different growth stages require a specific amount of light. Meaning, if you’re to use a single 1000w led grow light to supply lightening from germinating to the maturing period, such a product should have light controls that’ll let you adjust it to different stage requirements.
