Cannabis growth depends greatly on light cycles; these cycles correspond with the quality of your crop and your overall yield.

Advantages of Using LED Grow Lights in a 4×4 Grow Tent
Produces Healthier Plants
Grow lights serve as a replacement for direct sunlight; they provide the same UV, IR, and almost all light spectrum produced by natural sunlight. One of the benefits of LED grow light is that it can be dimmed and adjusted to suit the plant. When planting outdoors, the heat may get too much and cause your plants to dry up fast, maybe even burn. But LED grow lights don’t emit as much heat as other grow lights. If you notice the grow light producing too much heat, you can always adjust the light, so your plants get just the right amount of light. You produce healthy plants because you are in control of what your plants get and when.
Larger Yield
Light from the grow light promotes photosynthesis, which is a way plants manufacture food for their growth. This allows your plants to grow well and fast. Not only does the light promote growth, but the light can also fasten their growth. Since you are in full control over what your plants take in, you can decide to leave the lights on during the day or night. This increases the growth rate of your plants, allowing you to produce a large yield and even have more than one harvest in a season.
Energy Efficient
Unlike incandescent bulbs which was banned because it consumes too much energy, LED grow lights are known to be very efficient and energy conserving. You don’t need heat to produce light; all you need is an electric current. Not only does it help you save money, but it is also eco-friendly. The lights can be recycled and don’t contain toxic substances found in other lights.
Produces Full Spectrum
LED grow lights offer a full light spectrum that is just as balanced as sunlight. This allows your plants to different lights in the right amount. You can also adjust the wavelengths or just turn it off depending on what your plants need. This is an added advantage over traditional lights that offer yellow and green wavelengths to your plants. These wavelengths weaken your plants and change the color of the leaves. LED grow lights provide enough red and blue spectrum, which is the best for plants at any growing stage.
Longer Lifespan
Durability is not a problem with LED grow lights; a regular LED grow light has a lifespan of over 50,000 hours. You can use the light 24 hours every day for about six years. You don’t have to worry about replacing the light even if one of the light chips goes off. LED grow lights would keep your plants growing for many years. With a 4×4 grow tent, you won’t have to buy many lights before your plants get what they need to thrive.
How to Buy the best LED Grow Light for Your 4×4 Grow Tent
LED lights have their different capacity and wattage; this makes them very different from each other. When looking for a grow light for your 4×4 grow tent, there are some things you need to consider. These factors help you narrow your search to the best capacity and type of LED grow light you need. Some of these factors are:
Heat
LED grow lights are known for producing light, but a few of them produce more heat. Heat is good for plants, but when it’s too much, that can be a problem for your plants. If you don’t mind getting a little heat from your grow light, you can get any LED light without thinking too much about the heat it emits. But if you prefer it only to be a light source for your plants, look out for light or light bulbs that don’t consume too much power or give off heat.
Durable Material
LED grow lights have become very common among indoor gardeners; this makes it possible to find a couple of low-grade lights before finding the best one for your plants. Most low-grade lights flicker and produce too much heat, which is very bad for your plants. Search for LED lights that are built with durable material and don’t overheat. If the light overheats, not only would it ruin the light unit, it could also damage your plants.
PAR
PAR stands for Photosynthetically Active Radiation. It is the amount of light produced by the bulb that can actually be used for photosynthesis. LED grow lights usually have their PAR values in their specification, depending on the brand. A high PAR value doesn’t necessarily mean the grow light is good; if it falls within the best PAR value needed for the 4×4 grow tent, it is the best for your plants.
Cooling System
As mentioned earlier, LED grow lights tend to overheat, especially if they’ve been in use for more than 15 hours a day. Excess heat is very bad for your plants and the light unit. A good quality LED grow light is built with a heat sink that helps to keep the unit and the area around it cool.
Programmability
If you purchase an LED light that can be programmed, you’ve hit the jackpot. With this type of feature, you program the LED light to suit your needs. You can program light schedules and control the growing cycle of your plants. You can set a time you want the light to turn on or off. This makes it more convenient to monitor your plants; you don’t have to manually turn the lights on or off when needed.
Price
LED grow light is an investment that’s worth every penny. If you need to get the best, you must be willing to spend a bit more money. Regular LED lights used in homes are not cheap; it’s only reasonable that grow lights would be more expensive. There are cheaper grow lights on the market, but these lights may be of low standards and may not last long. Instead of looking for the cheaper option that would cost you more in the long run, you should opt for the expensive ones with better quality. Note that expensive does not always mean good; you should consider the other factors that have been stated before deciding on what to get for your plants.
