MarsHydro Mars600 LED Grow Light Review

The MarsHydro Mars600 is ideal for a small grow tent. As it uses LED bulbs, it doesn’t generate a lot of heat or draw a lot of electric power. You’re likely to upgrade to something larger before you have to replace it because LEDs last up to 100,000 hours, which is 30 years of growing!

Power and Light

MarsHydro uses 5W Epistar blue and red LEDs that generate a full spectrum for the maximum possible yield since sunlight. The purple grow that ensues is really nice, but you won’t be able to see the green, so you may need to use a regular light to check the health of your plants. The light’s noise is just 56dB with two cooling fans on top. That’s pretty quiet if you ask us. It uses just 2.488A of current on 110V or 1.234A on 220V and less than 300W of power. These figures will help keep your power costs low.

The light is UL-listed, which is good to know for the safety-conscious of us. Even if one chip goes out of whack, the light will still work thanks to the failsafe diode design. The full-spectrum light weighs 9.85 pounds and is equipped with a steel cable hanging kit.

This grow light offers cannabis plants their ideal spectral ratios from seed to harvest. It mimics natural outdoor lighting indoors.  The wavelength can be fully absorbed by the plants in all growth stages, including the vegetating and flowering phases.

The panel is 17 inches long, 11 inches wide, and 3 inches thick. The purplish light covers an area of 2.5 by 2 feet for vegetating and 2 feet by 1.5 feet for blooming. It depends on how high you put the light above your plants for each phase.


MarsHydro has developed and improved this grow light over a period of 8 years. It has thousands of happy users throughout the world, who appreciate its stable quality. The light satisfies all light needs of the plants irrespective of the growing stage. It is a result of careful, long-term quality control measures consistent with the growth needs and environment.


Here are some tips on how to use this light that you are not going to read anywhere else. Please read them carefully and take this information into consideration.

  • Don’t look directly at the light, because it’s extremely bright, and wear your sunglasses.
  • It is not waterproof, so use it indoors only.
  • Maintain stable voltage to avoid any damaged to light fixture.
  • Stop using the light when the fan stops spinning.


The Mars Hydro Mars 600w LED kit includes the grow light, one power cord, and one pair of steel hanging kits.

How to Use The Light For Maximum Yield

Some of the LEDs are angled at 120 degrees, others at 90 degrees. The light works on 50 to 60Hz and 85 to 265V.

Germinate, Vegetate, and Bloom:

To germinate seeds, leave the light on 18 to 20 hours a day.

For germination, position the light at 24 – 30 inches above the canopy. In the vegetation stage, it should be a bit lower – 18 – 24 inches, and 12 – 18 inches in the flowering stage.


We would definitely recommend the Mars600 to cannabis growers. It’s great value for money, and the customer service is also pretty good. MarsHydro actually give their clients growing tips after receiving their order.

We also recommend getting a rope hanger to adjust the height. If it happens to be missing a power switch, use a timer or plug and unplug it manually. It will work the same for what you need with your timers.

Delivery is nice and speedy – sometimes the lights arrive one or two days early. You can also use it as the center of several lights, with a supernova 300 watt on each side.

All in all, the quality, build and sturdiness of this light are amazing. It arrives safely packed, is very energy efficient and ensures fantastic growth if you use it right.
