MARS HYDRO TSW 2000W Led Grow Ligh

Mars Hydro TSW 2000W LED Grow Light 4×4 Ft. Coverage is a product of the Chinese company Mars Hydro. Though the parent company is in china, it has branches in many other countries that include the USA, UK, Australia, and Germany, among others. It is at the forefront of manufacturing some of the most quality LED grow lights for indoor farming.

All the grow lights from the company go through thorough testing before they go out to the farmers. The grow light, which provides core coverage of 3.5 by 3.5 feet and maximum coverage of 4 by 4 feet, comes with high-energy efficiency with low power consumption. The grow light provides broad-spectrum light, ideal for all stages of your marijuana growth phases.

The spectrum light mimics the natural light of the sun, which is better than HID, or the individual blue or red lights. Mars Hydro gives you quality peaks of both the blue and red lights coupled with IR. The red light helps to improve the plant’s photosynthesis, which is vital for the flowering phase.

The blue light helps to accelerate the plants’ growth for thriving health. The IR helps to stimulate the cannabis to blossom and yield more buds. With this light output and power input, you stand a better chance of harvesting more yields for the same area of coverage.

Reflective aluminum that comes with the LED grow lights ensures that there is an optimal balance between the coverage area and the PAR output, which helps to improve the efficiency of light. You also do not have to worry about any noises or heat dissipation from the lighting unit as it comes with a fan less design. The quiet atmosphere for growth allows your crops to thrive for high yields.

Another notable feature about the LED grow light is its dimmable abilities. You can control the level of brightness from low to high, depending on the stages and time of day. A silicone plug situated on top of the light, and a precision flat-head screwdriver, give you secure dimming options to program the veg and bloom brightness levels.

The design of the mars hydro is another feature that sets it apart from many other grow lights. The LED light unit uses SMD LED chip technology that helps to improve the quantity of your weed harvest with the least power input. The chip provides 50909lm at 120 volts.

The lighting system also comes with a long lifespan of 50,000 hours and works well in temperatures that range from -20 to 40 degrees centigrade. The range makes the LED lights the most efficient for growing through all stages of growth because they provide you with seasonable temperatures of your choice to work with for better yields.

The LED grow light is also one of the most affordable LED grow lights in the market, and it comes with a three-year manufacturer’s warranty and 30-day money-back guarantee.
