MARS HYDRO TSW 2000W Grow Light Review
Per usual it is a pleasure reviewing Mars Hydro’s grow lights. The Mars Hydro TSW 2000w review was no exception. Mars Hydro is a forward-thinking grow light manufacturer and when it comes to customer service for any of their lights including the MARS Hydro TS Series lights.
This particular LED grow light is an upgrade compared to LED grow lights that are just a few years old. It creates perfect full-spectrum light for indoor plants to thrive.
Best Grow Light For A 3×3 Grow Tent
The TSW 2000w is similar to Mars Hydro TSL 2000 watt Series but adds more coverage area with a wider quantum light board configuration at 3×3 feet during flowering stages. Perfect for a 3×3 grow tent, the TSW 2000w is easy to install and makes growing convenient.
From a PAR perspective, it has a powerful balance of grow lighting spectrum using balanced and natural white light, to the right mixture of red and blue grow light intensity. The PAR value falls at 910umol which is about perfect for the lighting spectrum cannabis plants grow best in.
Mars Hydro TSW 2000w Specs
The TSW 2000w also comes with a 3-year warranty which is pretty solid for the industry. Another great thing about this light is that it has no built-in fans for cooling. It simply does not need them because it is a solid unit that emits very little heat. Grow lights from just a few short years ago would require fans, but with quantum board technology this is simply not needed.
In fact, when comparing the Mars Hydro TSW series to COB LED lighting, you still get a full light spectrum of PAR without the noise of several fans buzzing away. The TSW 2000w model also comes with an angled stainless steel housing to re-direct lights towards your plants which increases its high efficiency ten-fold.
This grow light is also extremely bright so do not look directly at the light without grow room glasses. The TSW 2000 watt can also be dimmed in case you wish to adjust its intensity in veg or bloom sequences.
It is a bit annoying to use the dimmable feature as you have to remove a silicon plug on its base and use a screwdriver to adjust the power output. Not a deal-breaker as this is fairly standard with quantum board technology.
For the most part, the MARS HYDRO 2000w TSW is plug and play, meaning all you have to do is plug it in for the full operation. Of course, don’t forget your plants!
TSW 2000W Yields
The Mars Hydro TSW is a grow lighting full spectrum light beast. With its power efficiency, low profile, and excellent IR to help THC production we were pleased with our results while using this LED grow light.
We used only one TSW 2000 watt LED grow light to produce, in a VIVOSUN grow tent, just under 4 ounces for a single cannabis plant. Of course, this great light works great for other plants, but that’s not why you are here, is it?
We adjusted our lights, as you should, through each stage of plant development.
- During the veg stage, we set the lights at 18 inches at 18 hours on and 6 hours off.
- For flowering phase, we set our lights at 14 inches with lights on for 12 hours and off another 12 for this cycle.
All said and done you should be able to get around 1.5 grams per watt from the MARS HYDRO TSW 2000w LED grow light model.
I should note that I started this indoor garden with clones, so we did not hang them for germination or seeding. Mars Hydro recommends, for these important stages the following:
Recommended Lighting Time: Veg: 18/6 (on/off) or 20/4 (on/off) ; Flower: 12/12 (on/off)
Recommended Hanging Distance Above Plants: Seeding: 24″ ; Germination: 24″-30″ ; Veg: 18″-24″ ; Bloom: 12″-18″
Why A Quantum Board LED Like The Mars Hydro makes a difference?
For starters, the Mars Hydro TSW has little to no heat output. This means that you will not need to purchase cooling fans and systems. On top of that, the Mars Hydro TSW 2000w does an extremely good job growing big buds and performance at around 310 watts – see also the 3000 Watt model – while it gives an equivalent light output of a 1000w HPS bulb.
Not only do you get a tent that does not run hot and an efficient LED light, but speaking of the high-quality light that it produces, you would be silly to not consider this for your next growing season.
How do the Mars Hydro TS series grow light compare to other quantum board grow lights?
Mars Hydro’s TSW 2000w Quantum Board grow light compared to other quantum boards is by far cheaper and gives the same light quality plant growing lights deserve. They still feel high-end without a bigger price tag and use many of the quality components such as drivers and LEDs that similar brand names use.
Final Thoughts About The TSW 2000w quantum board grow light
The Mars Hydro TSW 2000w QB Grow Light is a perfect light for those interested in quantum boards (see also Bestva 2000W). At a price that is much lower than some other grow lights such as Electric Sky, it gives you a great entry point for exploring all that quantum light board LEDs offer.
This LED grow light has everything you need from veg to bloom and is made by a trusted manufacturer.

2. Is Mars a good grow light?
Yes, it’s a good LED grow light. Daisy-chaining is possible thanks to the new SMD technology. Their performance is much better than older versions, which have a greater problem with burnt diodes. This is an excellent choice for beginners. It’s an affordable light that is perfect for hobby gardens and low-cost gardens.
3. When did Mars hydro come out?
Mars Hydro has been in business since 2009 as a manufacturer of LED grow lights and grow tents. They have their own in-house research, design, development, manufacturing, and testing teams to support this excellent product.
4. How far should Mars Hydro be from plant?
At first, it is advisable to set the light at 24 inches above the soil if you are just starting your plants from seeds. The hanging height should be adjusted as the plants grow, bringing the light closer to their tops so they could receive the full benefit of the light.
5. Is Mars Hydro waterproof?
It is not. It is an IP65, meaning water resistant. It is resistant to water jets from any angle, but do not immerse IP65 LED lights because they are not waterproof.
HI MY DRIVER JUST WENT OUT ON ONE SIDE HAVING TROUBLE FINDINF A REPLACEMENT LED DRIVER
That’s a tough one Andrew. Those parts are hard to find and when you do locate them, they take awhile to arrive. Checkout this thread I found for you: https://support.ilovegrowingmarijuana.com/t/tsl2000-driver-replacement/77648/10
Consider googling the exact part model. “part_number + mars hydro replacement driver”
Most likely you’ll find an OEM in China but will have to wait a month for shipping.
I’m curious what you find — circle back if/when you locate a solution so we can share that info with others.
I’ve grown different autoflowers with this light in a homemade 3x2x6, two at a time with real good results. 3 years same light. I like turning down the power and lowering it over seedlings to keep them from stretching, and then raise it and crank it up for more light than necessary for a 3×2. It works :*)
That’s a super cool suggestion. What do you mean by “stretching”? I may add this tip to the post!
