Features of Mars Hydro SP 3000

Click to check more details

Highly-Efficient Greenhouse Light

Mars Hydro SP3000 LED grow light consumes only 300 watts but provides 727.2 μmol/s photon flux per second to indoor plants and has a high PPE of 2.8 umol/j, ensuring deep light penetration, reaching even the lower parts of your plants to foster uniform and robust growth.

High Light Penetration

Mars Hydro SP3000 light penetration is strong enough to bring photons deep down to the branches in the shadow. With the deep red of 660 nm wavelength in the spectrum, the light can penetrate through leaves and carry much energy. Thus, for cultivation rooms that have high hangers or high trusses (for example, greenhouses), SP3000 is the best grow lighting option.

Sunlike Full Spectrum

SP3000 outputs sunlike full spectrum lighting, perfect for all types of indoor plants. Enhanced the red light in the white light to make the SP3000 grow light perform well from seed to harvest for the full cycle of plant growth.

Advanced Cooling and Waterproof Design

SP3000 is a dimmable grow light that is easy to switch on/off and adjust the light level via the dimmer, which can help indoor growers easily meet the changeable PPFD requirements of various plants from the seedling, vegetative, and flowering, to the fruiting phases. If you have multiple LEDs, the Mars Hydro SP Series can be daisy-chained in series with one another so it’s convenient to control them with one master LED light. (up to 50 lights can be connected)

Quick Dissipation and Silent Cooling Designs

Mars Hydro SP 3000 LED Grow Light with an aluminum shade and thick heat sink, passively dissipates heat efficiently, maintaining optimal temperatures without noisy fans. Its IP65 waterproof rating ensures reliable performance in humid conditions, safeguarding your plants from heat stress and moisture damage.

Safety Certified & Excellent Customer Care

All Mars Hydro LED grow lights have been CE, ETL, RoHS, and UKCA certified, safe to use worldwide. Mars Hydro officially guarantees 24-hour customer service, a 5-year limited warranty, and local warehouses & repair centers to offer the best after-sale services to growers worldwide.

  32. Gwyn (Grower) – 19/10/2024

    Rated 5 out of 5

    Don’t know about how it works in greenhouses but my herbs absolutely adore it. The enhanced high red is like waving a magic over them. And the canopy penetration is unreal. Runs warmer than the previous light, but hey, no pain, no gain. If I have to look(very hard) for a flaw, my only concern is the longevity of the unit but it’s early days. For what it cost I’m not expecting three years, you never know though. Thank you MarsHydro. My herbs love you…. very much xxx

    Rated 5 out of 5

    “I have only had these for a few weeks, actually I have had 1 SP3000 for 3 weeks and I added the 2nd one a week ago. On 1/2 of my 4×8 text I have a Spider Farmer SF4000. 589$ light that is designed for 4×4 flower or 5×5 veg. By all means a pretty good light from all the reviews. I bought the 1st SP3000 the days before I flipped these 7 plants to flower. The first 2 weeks of flower I had 3 plants under 1 SP3000 in a 4×4 area. 4 plants were under the SF4000. I added the 2nd SP3000 to run next to the other 8 days ago, and moved 1 more plant from the SF4000 to the Mars Hydro side. The pictures are there but I am not even sure they do it justice, the difference is huge. 1 week under the 2 lights and I can’t tell the difference in the one I moved from the other side. All 4 are growing bigger buds then the Spider Farmer side. Ever the buds directly under the SF4000 in the hot spots still don’t match the Mars SP3000 buds. Yes, 2 SP3000’s cost 200$ more than the 1 SF4000 but the yield difference is gonna be huge.
    Look the the PAR map, that thing is legit amazing. I am soon going to get an apogee par meter and verify…but right now the results are right there in buds…good for you MARRS! These lights are awesome.
    I am considering a bunch of these for the new grow room I am building. How about a Black Friday sale Marrs? You cheap jerks would not even let the discount codes that can be used on your website work on Amazon…kidding I love you but seriously…give us a sale!”

    Just a perfect light for tent! I have a 5×5 tent and had this light and another one from a different company. The ones under the Mars light grew much fuller and produced more than the ones with the other light. I will be purchasing another Mars for my tent. It emits enough just the right amount of heat to keep it warm enough on cold days but not too hot. I purchased this after researching par test videos, and it was clear this was the best value for my money.

  45. Tyler (store manager) – 01/09/2021

    Rated 5 out of 5

    I’ve been waiting to review these lights until I saw some results, these plants are 2 weeks into flower and look pretty decent. I’m waiting to see if they come out as good as they would with an HPS, but so far, so good. They’re definitely brighter than a 1000W MH, but they’re so white, that’s the only thing that has me thinking the HPS are going to be better for flower. The put off very little heat though, so you won’t need an air conditioner to cool the tent like you do with the old schools. You’ll save a lot on the electric bill too, probably at least half since you shouldn’t need the AC unless you’re trying to make them turn purple.

    This is a great light!! Initially, I had an issue with it. It was consuming less power than advertised. So I contacted customer support and they explained various reasons why the power consumption off the wall could be different. They guided me step by step on how to unmount and change some settings for better performance but when explained I was not very tech-savvy they sent me a replacement without any issues. The company & its customer service were quick to solve my issues with their product. SOLID !!! The lamp itself its also great. I’ve been vegging with 60% power and my plants seem to love the light. I would recommend.

    Don’t think about buying this, just do it. Your plants will love you for it. 50% power for veg, and increase to 100% during flowering.”

    Just a perfect light for tent! I have a 5×5 tent and had this light and another one from a different company. The ones under the Mars light grew much fuller and produced more than the ones with the other light. I will be purchasing another Mars for my tent. It emits enough just the right amount of heat to keep it warm enough on cold days but not too hot. I purchased this after researching par test videos, and it was clear this was the best value for my money.

    Adjustable lighting is a plus. These lights have really amped up the growth for my plants. Light hangers are a bit wonky, just make sure you have enough clearance above plants. Great buy and SO worth the money!
