Mars Pro 2 Reviews – Epistar
Mars Hydro is known for its known for quality lighting for indoor growing, so we are apt to take the challenge. Dealing with limited Mars Hydro reviews we thought this would be a great start in our arsenal of articles relating to LED grow light reviews.Check Price
The questions in mind when growing cannabis indoors with this LED Grow Light are:
- Will it stand up to other lights in this category?
- Is this LED grow light comparable in class to other manufacturers?
- Will it grow an amazing plant?
- What is the quality like with the Mars Pro II Epistar 80?
- Is the LED efficient in its operating capacity?
Mars Hydro Pro 2 Overview
Manufactured by Mars Hydro and in business since 2009, the Mars Pro 2 Epistar being a newer light is starting to gain traction in the growing world. The Pro 2 series of Mars lights are a specialized brand of full spectrum Epistar LED’s designed for professional growers and one of the best in Mars Hydro’s LED category. With that said, the lights are truly affordable and can be used by amateur growers as well as seasoned professionals who know their growing stuff.
The Mars Hydro LED lights itself allow for daisy chaining multiple lights together, however, we were working with a single LED grow light along with the Mars Hydro 27 by 27 Mylar Hydro Hut Grow Tent in this case. The LED’s themselves are positioned within a “cup designed” cradle, much like that of cone lighting you might find in a home.
The purpose of these “cups” is to enforce the strength of the full spectrum lighting offered by these lights to mix the light spectrum perfectly as they shine down through the canopy of your plants while they grow.Check Price
Upon inspecting the arrival of these lights, we were impressed once again by Mars Hydro’s ability to produce a solidly engineered LED. From the power supply to the fans everything in the pro series has an upgraded sense of quality. The chipset is the best that Mars Hydro offers and was proved through our final grow, but we will get to that later
A powerful LED in its class. The Pro II Epistar is the newest in the Mars Hydro product line up. Adding stable PAR values along with stable Lumen output we found our plants to grow quickly over our product review for this light. There is no glass cover over the LED’s and instead, sit within a reflective cup to overproduce light in a good way.
Of course whenever you use full spectrum LED’s you should always use protective eyewear. Our favorite for cost, effectiveness and looking cool are the Apollo Horticulture protective lenses below:
The “80” in the Pro II Epistar 80 refers to the number of Epistar led chips in this unit and not the wattage which the light produces so don’t let that throw you off. The light can replace a typical 300 – 400-watt HPS bulb.
At the same time, the light consumption itself is around 178 watts which will save you big time on your electricity bills. All the while covering an area of 2 feet by 2 feet which is recommended for plant growth and a maximum area of 3.5 feet by 3.5 feet.
The fans are also whispering quiet and are combined with an internal aluminum radiator (heat sink) system which moves heat away from your plants and cools things down fast which is perfect for hydroponics and for all plants growing in soil that typically grow in full sunlight such as cannabis.
I also can’t say enough about Mars Hydro as a company. They have wonderful customer service people who are there to help and seem to love their jobs. That combined with an industry-leading warranty of 3 years or 30-day money back guarantee, you know they stand behind this product should you want to return it for some insane reason. We aren’t sure why you would.

Mars Pro II Epistar 80 Unboxing Video
Our Mars II 400w LED Review
We started this review off with an unboxing of our Mars Pro II Epistar by noticing the packaging comes in very discreet packaging, so prying eyes and nosy neighbors won’t know what you are up to in case you are into stealth grow boxes. I live in Colorado, so we were not too concerned with it, but the light itself was packaged very well and protected nicely. Arriving perfectly intact.
We were initially impressed with the Mars 400w LED grow light’s unique design and sleek surfaces. The light did not appear flimsy or cheap. Strong light and the pro series seems to be a well-manufactured piece of equipment.
We specifically enjoyed its silver “spaceship” feel and materials to which it is constructed. Noticeably are the cup-shaped sockets the chips are placed into at 100 degrees. This is said to enhance the LED light strength and focus the spectrums to where they need to go – The Plant itself.
We started with a seedling for this grow. Using a Sativa Hybrid known as a red-headed stranger as a tribute to Willie Nelson. It is truly a low paranoia strain that has sweet and spicy aromas and a cerebral effect on the mind. A classic and a good strain choice with the light intensity that the Mars Pro II Epistar 80 LED grow light puts out.
We began by setting up the easy to use Mars Hydro 27 x 27 tent and stringing up the Mars II LED light with the included hanger. The installation was effortless and the LED hanger was strong and easy to maneuver with our pully system as the plant grew to new heights as expected.
Mars II Pro Epistar 80 Heat Dissipation
The built-in fans and heat sinks are very professional. The Mars Hydro lights remained cool to the touch due to the heavy-duty heatsink and quiet fans. There was a bit of noise produced but nothing like some of the cheaper LED grow lights out there and the fact that you don’t need multiple extra fans running keeps the electric bill down, saving you money in the long run.
Having a low heat signature in your grow tent is a must and with Mars II 400 this is not a problem.
Mars Pro 2 Epistar 80 Yield
The LED light itself seemed to outperform others in its class. This is probably due to its “cup” designed LED chip sockets that seem to do a great job of producing quality full light spectrum that concentrates the light on your plants at just the right angle or in other words a 100-degree angle bolstered by its reflective cup module. Our yields were impressive, to say the least, compared to the Viparspectra 450w reflector series that we recently reviewed.
After curing and drying our bud there was nothing left to do than test out our final product. Trichomes were nice and sticky and produced a flower that was out of this world great.
Our “red-headed stranger” was perfect, producing just under 1 gram per watt with this bulb resulting in 114 Grams of the kind herb. Roughly 4 ounces in total. This was with a total of 9 weeks in flower. Not to bad for a signal LED grow.
The higher and better quality yields with the Mars Pro 2 Epistar are due to the incorporation of the single chip board that processes the right PAR for your plants at the right time.
