Review: Mars Hydro – TSW 2000

Growing cannabis at home is becoming increasingly popular. However, since conventional grow lights consume an incredible amount of power, the focus has shifted to LED grow lights. Not only do grow LEDs offer the same light intensity while consuming much less energy, but they are also designed to illuminate your grow area for much longer periods of time and can even come up with a much more favourable light spectrum.

There are many LED lights on the market today, which can make choosing one very difficult. Therefore, we are excited to introduce you to one of the latest developments in LED grow lights — The Mars Hydro TSW 2000.

Mars Hydro is a professional grow light manufacturer that has specialised in LED grow lights. In recent years, it has dedicated itself to bring high efficiency and high yield full spectrum LED grow lamps to the market. Currently, the brand offers more than a dozen different illumination devices ranging from amateur equipment to highly professional gear.

After two months of reviewing the Mars Hydro TSW 2000, we can now present our evaluation based on the most important aspects when choosing an LED grow light.

Light intensity

Light intensity is one of the most important factors when choosing an LED grow light. Generally speaking, you always want the right amount of light for the particular growth stages your plants are going through.

The Mars Hydro TSW 2000 is suitable for an area of 4 ft x 4 ft (120 cm x 120 cm) and comes with the latest SMD LED technology — short for Surface Mounted Device. One of the biggest improvements in this technology is that SMD lights offer higher lumen output with lower energy consumption, making them more powerful and energy-efficient than older LED lights.

While researching the topic of the light spectrum and plant lighting effectiveness, you probably came across PAR (Photosynthetically Active Radiation) readings, which is an indicator of the part of the light spectrum that plants use for the process of photosynthesis. It should be noted that PAR is not a measurement or metric, but defines the range of light needed to support photosynthesis.

In our estimation, the Mars Hydro TSW 2000 delivers impressive performance with a PAR/LUMEN output of [email protected]″. According to the manufacturer, this enables a yield increase of up to 30 percent compared to old LED lights.

Also, when looking at the PAR diagram of this lamp, which shows how intense the light is in a certain area and how this light is distributed over this area, we see a fairly uniform PAR diagram. A high uniformity indicates that there is not much difference between the numbers in the centre and at the edges & corners, which is ideal for most growers.

Compared to other brands, the Mars Hydro TSW 2000 is thus able to deliver high light intensity over the entire growing area, ensuring that your entire plant is optimally flooded with light, allowing it to realise its full potential. Another great advantage of the Mars Hydro TSW 2000 is that its light intensity can be adjusted individually. With the dimming control, you can adjust the light intensity to the different growth stages of your plants and thus save electricity.

Light spectrum

Depending on what stage of growth your plants are in, you may want to make sure you choose the right spectrum. Since most of you will be completing a full cycle grow from seed to harvest, it is advisable to choose a lamp with a wide spectrum.

The reason why opting for a full spectrum light is much more beneficial than, say, just a cool or warm white light or even a ‘blurple’ light is that a plant will require different spectrums of light during its lifetime.

Furthermore, recent scientific research has shown that green light, which was previously thought to have no significant impact on plant growth, is also important for achieving good results.

The Mars Hydro TSW 2000 is a sun-like full spectrum LED grow lamp that impressed our testers with its great light spectrum and decent efficiency. The Mars Hydro TSW 2000 model comes with a total of 684 PCS LEDs, including 3000K warm white light, 5000K blue light, 660 nm red light and 730 nm infrared light. This sun-like light spectrum is ideal for cultivating all types of plants, including cannabis, during both the vegetative and flowering stages.

Power consumption

The true power consumption of the Mars Hydro TSW 2000 is 300 watts. According to Mars Hydro, it can produce yields of up to 2 grams per watt, meaning that, at full capacity, the Mars Hydro TSW 2000 could yield up to 600 grams. However, we have to note that that the estimations on maximum yield have been stated by the manufacturer and we were not able to assess whether they are true.

Additionally, one should consider that the light of the Mars Hydro TSW 2000 is dimmable, which allows you to customise the power output according to your needs.

Overall product

In conclusion, we can say that Mars Hydro TSW 2000 is without a doubt suitable for growing cannabis plants. Moreover, it is one of the best quality lights on the market at a great price.

What we liked, in particular, was the sun-like light spectrum of the Mars Hydro TSW 2000. Considering the price of $259.99, we can truly say that it offers amazing value for money.

However, even though Mars Hydro has significantly improved the quality compared to its previous products, other more expensive brands like Sunlight and OpticLED are still better choices for professional growers and those who value high-end technology.
