A thread for the users of Mars-Hydro lamps

[Skullman420]

I just noticed this in the official Mars-Hydro thread. These are my favourite Mars-Hydro series. I grow all my buds with the Pro series and I can't let this go unnoticed. you need 4 of these to fill a 4x4 tent. They should have a deal for 4, but except for that this is a great deal.

Check out the price.

If I were to buy lamps for my grow-room now, I would rather have bought 8 80's than 2 320's. But they didn't have the 80's back then. With several small lamps it is possible to use a check system on the lamps and get away with using only half of them at once. That way you can reduce your electric bill to the half and still get the same amount of weed.

I'm thinking about this system - The 80's are perfect for that

 

[Skullman420]

Wish I had 8 of those lamps for my next grow-room setup. Check out the plan

 

[Skullman420]

If I were Mars-Hydro I would use this growing system as a reason for why to buy many small lamps instead of few big ones. One can save a lot of money over the years by using only 50% of the electricity. Really good sale-pitch. You should make notes @SmokeSara

$663.96 to adequately illuminate a 4'x4' tent? What a deal, lol. Although, at 680 watts (total), it'd be cheaper in monthly electric use than a (much less expensive) 1Kw HPS. But most people would probably choose a 600-watt HPS instead of a 1,000-watt one for a tent of that size (not really sure why, lol) which would be in the same general range as far as power consumption.

Hmm... Now you've got me wondering which would perform better in a 4'x4' space - those four blurples or one 600-watt HPS (I would guess that the 1kW HPS would outperform both). The LED panels ought to produce a more even light distribution. I would guess that the 600-watt HPS would have them beat on penetration. So much would depend on the HID's reflector, since many of them just don't broadcast a square-shaped footprint - but it'd be far easier (and... possible ) to separate the heat from the smell with the HID. You know what? I don't think I'd care to bet a dollar on either to win, lol, because I couldn't predict a clear winner. Be an interesting side-by-side grow for someone that had the money and electrical capacity.

4 of the 80's = one 320
one 320 equals 800 watt of HPS

That's the data I've been relating too since I bought the pro-series, so I think it would beat a 600 watt HPS, but not a 1000 watt

 

[Skullman420]

Here's the data for the 320. Mars-Hydro don't lie on the wattage like many others. I am certain many others would have advertised the 320's as 1500-1600 watt or so. The LED business is ridiculous

PS! I do know HPS is MUCH cheaper than LED. I used to grow with them myself and I honestly think you're wrong in regards of penetration. The 5watt chips penetrate very deep. The old 3 watts didn't

 

[Skullman420]

What kind of light are you growing with Tortured?

 

[Skullman420]

I want to tell you why I like the Mars-Hydro company. Everyone can sell you a light. That's the easiest thing in the world. It's how you deal with the customers when the lights break down - that is what defines a company. And LED lights have many parts, so they do break, it happens. Most companies would tell you to send your lights away to some service center - perhaps in a country far far away.

Now - Mars-Hydro also have this option - And that's cool, but I wouldn't want to have a light I could not fix myself and here's where Mars-Hydro shines. They let us open the lamps (ask them for permission first or else you void warranty), they make videos on how to repair the lamps and they send you parts express. They have your back throughout the grow and they don't charge you shit for the parts the first two years. The third year they expect you to pay postage yourself

I Have been growing for a few years outdoor but I just harvested my first indoor grow. I done alot of research ( about 7 or 8 months worth) before purchasing my light, I went with the Mars 1200 in a 4×4 tent and had great results, the plants love the light. Out of six auto flower I ended up with right at 23oz dry, I set my goal at one pound and I never dr I would have yielded that much. Here are the last three that I harvested, I also went and bought another Mars 1200 and another 4×4 tent. I would recommend Mars to anyone, if I can pull 23oz indoors on my first run then anyone can but one thing you need to get good yields is a good light, Mars light will definitely grow some big, sticky, and dence buds. Keep gro everyone.

 

[Skullman420]

The Mars 1200 replaces a 600 watt HPS if I don't remember wrong. They're much cheaper than the pro-series and they use the same 5 watt diodes. A little harder to fix, but not impossible. Did you ever try to fix one?

 

[Skullman420]

23 oz is a little more than one gram per watt. Great work!

 

[EastCoastGhost]

23 oz is a little more than one gram per watt. Great work!

No I've never tried working on it yet, I haven't had any issues so far and I'm on my second grow now. The new one I bought is setup but I haven't used it yet.

 

[EastCoastGhost]

23 oz is a little more than one gram per watt. Great work!

I made a big rookie mistake already on my second grow, I had nute water for my flowering plants and I accidentally gave my seedlings nutes lol. That has set me back a little bit but I have some photo seeds ordered and I will fill my new tent with the photos and leave my burnt autos in my old one, I have 12 of the autos so since I have already made big mistake I will keep the best 6 or 7 and discard the rest. I can't believe I made such a big mistake already but that learned me a valuable lesson on keeping everything organized lol.

Or you just get really good solar panels to power your grows. And say fuck the power consumption.
Telsa makes some really cool shingles that are all solar panels. I personally have panels to run my heat pumps and hot water systems. So it allows me to add a few more lights and don't even notice really on my bill.

4 of the 80's = one 320

I'd actually consider the four 80s to be better than one 320, simply because they can be spread out to suit the grower (and/or the grow space, if its area is not square in shape).

one 320 equals 800 watt of HPS

Here's a grain of salt to season that meal with .

They might be right, IDK. I just get suspicious whenever I see a seller state that one form of illumination "equals" another. Have ever since CFLs came out and such advertising confused a lot of people (perhaps intentionally).

That's the data I've been relating too since I bought the pro-series, so I think it would beat a 600 watt HPS, but not a 1000 watt

I'd tend to... tentatively agree with your opinion. But that's just a guess.

Here's the data for the 320. Mars-Hydro don't lie on the wattage like many others. I am certain many others would have advertised the 320's as 1500-1600 watt or so. The LED business is ridiculous

Yes, I'll give them points for that. Not sure if it makes up for the deduction caused by products such as the Mars 300W that's actually a ~132-watt device, though.

Compare to HPS/MH/HID:800watt

Draw power:110V:Growth:350W±5%|Bloom:740W±5%

THAT I'll give extra points for, lol. Seems much more realistic.

Coverage:4'x4'

Hanging System:Seedling:24”-30“ Growth:18”-24“ Bloom:12"-18 "

Here's something I've always wondered: If you hang one of those things @ 12" - or even 18" above the ground, and measure the footprint, is it actually a 4'x4' pattern? Or somewhat smaller? I've often thought that manufacturers/sellers were a little off on their footprint estimates (this is NOT specific to Mars-Hydro, BtW, but a general opinion about LED sellers).

To be honest with you, the kinds of specifications I'd really like to see for lighting products are "maps" of how much light is actually hitting the ground (as if it were the top of the canopy), across the entire advertised footprint (and in a room the same size as that advertised footprint, with reflective walls), at the recommended flowering height. With data points every 6" or so, and expressed in PPFD / μmol per m² per second, etc. This kind of thing is still all too rare in the LED grow light panel marketplace (although it does seem to be getting better).

What kind of light are you growing with Tortured?

I'll have to answer that via PM, because the company used to be a sponsor but (I think) no longer is - and I don't wish to take the time to refresh my knowledge of the "LED Guidelines," to break same, or to go on a rant this early in the day.

I want to tell you why I like the Mars-Hydro company. Everyone can sell you a light. That's the easiest thing in the world. It's how you deal with the customers when the lights break down - that is what defines a company. And LED lights have many parts, so they do break, it happens. Most companies would tell you to send your lights away to some service center - perhaps in a country far far away.

Now - Mars-Hydro also have this option - And that's cool, but I wouldn't want to have a light I could not fix myself and here's where Mars-Hydro shines.

They have your back throughout the grow and they don't charge you shit for the parts the first two years. The third year they expect you to pay postage yourself

Err... That's called a warranty . I find three years to be somewhat short for a product that has an advertised lifespan of 50K hours, since even if the owner plugged the product in and never unplugged the thing, that's almost 5¾ years running 24/7/52. And it think it's pretty lame for them to charge the customer shipping on warranty parts that third year (maybe the company also sells tires and batteries, lol?), especially since - by sending you parts - it means they don't have to pay some kid to do the repair for you. And about that... Don't get me wrong, I consider it to be a feature, too, because it ought to mean less down time for one's light (which seems rather important, all things considered). But it does tend to save the company money, so it's not exactly an altruistic move on their part; more like something that benefits BOTH the company and the customer. Which is good, of course. Yeah... Points for that one. Anything that'll decrease down time gets extra points.

BtW, my light has a five-year warranty, lol (and, yes, they also make the customer pay shipping towards the end of the coverage period - years four and five). I can't honestly say how good it is, whether or not they'd allow me to self-diagnose and agree to just send me parts, et cetera - because I haven't found any real discussion of product failures via web search, lol. Mine has only been running... IDK, a year and a half? Something like that here, but it was also used for a few grows by one of the "company reps" before that. IDK its actual age; it's about three generations behind current, now, and I have a suspicion that it might have been a prototype for that. Whatever its age, it's old enough that it has Cree CXA2530 COBs - which were advertised at the time as "next generation" technology. And the ten individual monocolor LEDs that surround each COB are "five-watt" class; IDK what class the newer ones of those would be these days. "Ten-watt" class? I don't guess it really matters, since no manufacturer drives them at power levels which match their "class" designation :rolleyes3 .

PS! I do know HPS is MUCH cheaper than LED. I used to grow with them myself and I honestly think you're wrong in regards of penetration. The 5watt chips penetrate very deep. The old 3 watts didn't

It's been my experience that a proper canopy of cannabis (deep in flower) will block just about any useful amount of artificial light from penetrating below it. I used to grow almost exclusively using the "scrog" method and I had one of those headband flashlights that I'd have to use for reservoir maintenance and such, because there wasn't enough light below the screen to see what I was doing.

Speaking of penetration and such... does that new M-H hybrid light you won have a removable lens below the COB? My panel came with six of them and it turned out that at the height I could raise the panel to in the setup, they gave me bleached tips (well, more than just the tips, actually). Just too much focused intensity, I suppose (IIRC, they're recommended when using the panel for "medium- to high-bay applications). So if it does come with a lens for the COB, you might want to experiment both with and without it in place.

All in all, I think more highly of Mars-Hydro than most Chinese LED manufcaturers/sellers. I kind of remember when a rep from the company first joined the forum. They weren't selling product then, IIRC - they were asking members what was wanted in a grow light. Yep... more extra points for that, lol. And they've been a faithful long-term forum sponsor (more bonus points ) that has done more than just cut a check each month; they donate prizes for the contests (I think...?) and I've seen the rep participate in other threads than just the ones created by that rep. I'm a big fan of sponsors who actually participate in the forum.

I used my Mars 1200 and I also growed some photos and a couple autos under 600w hps. I had my tent full of autos with the led and the two autos under the hps was same strain ( white widow and thc bomb). Not only did my autos yield more under the LED the quality and tric production was alot better under the LED also. Now the autos under the hps was on 12/12 with my flowering blueberry and the ones under LED was 18/6 so I expected the led to yield more but I didn't expect the quality to be that much better, it was unreal. I am a rookie grower so I'm sure hps can grow nice quality bud but I'm I like my led alot better.

23oz dry

Congratulations. That looks like a nice harvest!

The Mars 1200 replaces a 600 watt HPS if I don't remember wrong. They're much cheaper than the pro-series and they use the same 5 watt diodes. A little harder to fix, but not impossible.

What's the difference? Do the older models use soldered connections and the newer ones are completely modular / have plugs for all the components? Or...?

That's a mistake I have done several times, latest 2-3 days ago when I filled my 220 liter tank I wasted 800 ml of good vegg nutes on my flowering plants. I realized the mistake a few hours later and emptied the whole tank and used another 800 ml of flowering nutes
