“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.

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.

Worth every penny!

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.
LannaM (store manager) –
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.”

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!
