3 Best LED Grow Lights for 4x4 Grow Tents (2022 Updated)

 There is an increase in the number of people moving from the countryside to big cities nowadays to look for work and education. This has led to high demand and low vegetation production since few farmers are left to cultivate in the villages. The open room cultivation can longer support the people in towns with food crops, promoting indoor gardening. However, Indoor gardening requires the right lighting option to create a quality environment for plants to thrive. In this article, I will discuss the Top best led grow light for 4X4 grow tent reviews, doing indoor horticultural, stress-free business for farmers.

What Are LED Grow Lights?

An LED (short for light-emitting diode) grow light is a type of artificial light that is used to mimic the sunlight, thus improving the growth of plants that are grown indoors. Many light arrays on the market today also allow for customization of spectrums.

This means with LED grow setups cultivators can turn up the blue light during the vegetative cycle and then switch to a more red-dominant spectrum during blooming for maximum flower development. Spectrum modulation is much tougher to control with compact fluorescent lights (CFL) and high pressure sodium lights (HPS).

Additionally, LED lights are highly energy-efficient, which can pay huge financial dividends with larger grow operations. The light waves that most LED grow lights emit are primarily blue and red in color, and it is those same light waves that allow the plants that are positioned underneath them to grow.

The blue light in particular helps to improve the process of photosynthesis, which stimulates stronger roots (which is why blue is more commonly used during vegetative stages where establishing a healthy root base is critical).

Red light on the other hand tends to respond to the Phyotochromes, which are responsible for the leafy growth of the plant which is helpful during the flowering stage where the plants are putting all their energy into juicy bud/trichome production. LED grow lights can be all red, all blue, or can produce light waves in both colors at varying intensities.

How Do LED Grow Lights Work?

LED grow lights work differently than fluorescent lights, as they use two different types of semiconductors. These semiconductors include:

Holes, which have a positive charge
Electrons, which produce a negative charge
When combined, these two semiconductors produce their own spectrum of light, which serves as an excellent alternative to natural sunlight, and can help to support the health of indoor plants, allowing them to grow faster and healthier.

Other types of lights use lead, mercury, or filament to generate light; however, LED grow lights are different in that they use semiconductor chips to produce the light spectrum they generate. This, in turn, makes LED lights more energy-efficient and environmentally-friendly; plus, they last longer than other types of grow lights.

Why Use LED Grow Lights?

There are a few different types of grow lights on the market, but LED lights are by far the best option for indoor plants. Though they are more expensive to start with, they last longer than fluorescent lights or grow bulbs.

LED grow lights are also more energy-efficient. They generally use about half the electricity of their fluorescent counterparts. They also don’t use glass, so they are less likely to break. If you’re worried about the amount of heat that the grow lights give off, LEDs are the best option. They put off very little heat during use, and you can use them for many hours at a time.

Overall, LED glow lights are a better long-term investment. Many LED lights can change colour and temperature won command, so you can use them for all of your plants.

Light Colour and Temperature
The colour of the light that a lamp produces is important. This is because some colours are better for certain types of plants.

Blue light is good for leafy plants, such as vegetables.
Red light is ideal for fruit plants and flowers.
Ultraviolet (UV) light helps your plant with the photosynthesis process, so it’s great to have.
Infrared (IR) light is beneficial for fruiting plants, as it helps them bear larger and more numerous fruit if used during growth.
Some species thrive will full-spectrum light, which encompasses all of the light colours on the spectrum.
When choosing a grow light, it’s important to choose the right colour for the type of plants you’ll be growing. However, it’s always worth looking into full-spectrum lights. LED lights are usually full-spectrum, meaning they contain the right light colours and temperatures to help all of your plants grow best in all of their life stages.

Wattage
While other types of grow lights measure effectiveness in lumens, LED lights are measured best when in wattage. This is because of the full-spectrum capabilities of LED grow lights. Brightness, as measured in lumens, isn’t a factor for LED lights. On the other hand, the wattage will tell you how intense the light is.

A higher wattage is always better because it means that the light is stronger. LED grow lights with stronger wattages usually yield a higher volume of viable plants.

Ratings
There are a few different ratings or measurements that a grow light company might use to explain how well their light works. Here are a few of the more common ratings and what they mean for you.

PAR light is representative of the type of light that is best used for photosynthesis. While this isn’t a way to measure how effective a grow lamp is by itself, other ratings are based on this figure. The PAR may be different for each plant.
PPFD, of Photosynthetic Photon Flux Density, is the intensity of PAR light that reaches your plants. It’s measured as umol/m2/s. The best LED grow lights in Canada have a PPFD rating of more than 500μMol/m2/s. If the light you’re choosing includes this rating, look for options above this level.
Note that most PPFD ratings are given at a certain distance from the plant, which should be noted in the ratings.
PPE, or Photosynthetic Photon Flux, represents how efficiently your grow light can create PAR-rated light from electricity. It’s one of the most important measures of grow light efficiency, and it’s measured as umol/J. Grow lights need a PPE of at least 1.5μMol/J to be effective, so look for lights that exceed this.
The PAR rating of each plant may change, but that won’t affect the light itself. When you’re shopping for a grow light, make sure to compare the PPFD and PPE ratings to help you make your decision. With both of these ratings, higher numbers mean better lights.

Coverage Area
The size of your LED grow light panel determines how many plants you can grow underneath it. Before making your choice, consider the number of plants you’ll be using the light for. Always buy the number of lights you need for your plants, as one fixture can only cover so many plants. Many lights will tell you the max area they can cover, so make sure to pay attention to these specifications.

Conclusion

Growing your horticultural plant in a 4X4 ft tent using LED lighting can be an enjoyable journey and experience. You have the right to choose between multiple lights or a single higher watt grow light option. This article reviews the best-led light for a 4×4 grow tent to help you make the right growing environment decision for your horticultural business.

Whether you are a beginner or veteran gardener, these recommendations will guarantee you save much of your time researching. It is advisable to invest in multiple LED grow lights as they allow more flexibility, optimal harvest, and power-saving advantage. Another great benefit of multiple lights is that you can always turn off some lights to reduce the growing area.
