Is A Mars II 400 Worth a Crap?

With Mars you get what you pay for. If you want to get into LEDs cheaply and hope to recoup the cost after 1 or 2 crops then Mars are good for that. Just don't expect long life from them or as high yields as better quality LEDs and drivers. One thing you could do to try to prolong their lifespan would be to take the drivers out of the fixtures and locate them remotely. I find a 240v 1050 ma driver is fine without any external heatsinking other than sitting it somewhere in the open where the heat can dissipate. But they do get very hot, so they need to be removed from the fixtures if you want to get the most from your LED heatsinks.

I disagree, I bet you will still use the exact same cobs you have now as side lighting 10 years down the road.
Possible but I doubt it. I generally use tents and the need for side lighting is of less use than in open grow spaces. Someone else may be using my old lights though. They tend to get passed on.

I sure hope my cobs last over 10 years of 12\12, thats the point. TOP of the line COBs of today will grow the same great weed 10 years down the road why would you upgrade so soon? like I said earlier, my af600s are well over 3 years old now and they are still rocking and should be rocking many more years. Still grows fire weed.
That is true, but I like making them and the upgraded too much to be using the same lights in 10 years. Maybe once my fiancé and I buy a permanent house that'll change, but for now my grow spaces change a lot and so do my lights.
at this point probably around 2500 watts in the bud room.
That's pretty beast lol. That's a fairy large investment on your part.
no ac unit with COBs, so you do save more. plus if you keep ladybugs in the grow room COBs are way WAY better than HIDs lol
i didn't run ac with my hid either for my personal stuff. Rooms and houses it gets necessary, but would still be necessary with cobs if you were running that many lol. What I will say is you can upgrade your diodes/arrays fairly easily and cost efficiently if you ever did want to upgrade. You can usually keep all the innards so that cuts a huge portion of the cost down. And with drivers running at ~95% efficient anyway. There's not much room to go up there. But in 5 years I can totally see 90%+ efficient arrays. Which, at that point, I may stop upgrading so often lol.

I got into LEDs shortly after I got into growing weed, so I didnt spend the money all at once hehe, but I did spend a ton of money on junk lights too... especially 4 years ago!!!

It happens. I got lucky with the one honest box I got. It's actual draw is about 150 but it pulls weight. My 100 watt cxa panel does about the same and draws about 110 from the wall.

So does inscadent lighting
side by side they might not be the best light out there but if you prefer to use LED's and want to do it cheaply it is a way to go. Hopefully one gets a few runs out of them and can then make a decision to pursue more or a better light. It isn't a bad starting point at all but the constant negativity over shit most people have never even plugged into their own wall is entertaining.

Why pay a company that makes false claims and uses sub-par parts and tech? That's the only reason it's more affordable, is that it's using garbage parts. Sure, it's got a nice spectrum. It has no footprint, it doesn't do what it claims to, and there are plenty of nightmare stories about their performance right out of the box, entire modules burning out in less than a month. And the Warranty process is a huge PITA. Why the fuck would I give a company like that any money? In fact, I would actively advocate against giving a company like that ANY money, as they have no business being in business.

Am I? Then give me a good example. What did you do with your Mars fixture? Over what footprint did you do that? I've been around LED grows for the past 4 years and I watched an associate go through the ringer with Mars. The low cost was hardly worth the questionable reliability. He switched to KIND. Marginally better while way more expensive, still extremely unreliable, but producing quite well.

Let me put it this way... Mono panels are not very good and are barely scratching the surface of the benefits of LED technology. Red diodes are inefficient to run, they require a bit more energy than blues for the same output. With so many different bands and runs, your chance of fault increases exponentially...

Their PAR is lacking, and I'm being serious, I've seen some pretty good bud grown under T5. The LED might produce frostier,denser nugs, but the T5 would outproduce it noticeably.


I found that to not be the case, you are spouting out horse shit dude stop being silly.

Wow I went to sleep and the otherside of the pond woke up and took to the thread with sledge hammers and thus begins the psychological kungfu in the world of grow lighting.

I can recall a time in the 80's when some people I knew got me into HPS and HID from Sylvania, everyone said "Why wouldn't you just grow outside it's to expensive, not a good return, etc..."

They'd never heard of flood and drain back then, and let me tell you they all came over to the darkside of HID and HPS over the next 10 years.... seems like another lifetime ago now...

Seems like a lot of doubters out there regarding the cob diy path, well I'm traveling with others on this and I've got a feeling all those doubters will be like the anti-HID/HPS people way way back in the olden days, and some may even have to eat humble pie.

To all that advance our knowledge of lighting and building a big thank you.

Mars will produce some really nice flowers ...I've have a Mars 2 900w in my 3x3 for the past year with solid results. Are there better more expensive lights? Of course there are... But for a grower on a budget I'd totally recommend...the only dicey thing is their warranty...they'll send you replacement and you have to replace it yourself....so that's the catch

Don't do it... you'll be more than likely very sorry... a lot of us are... Another crappy Mars Hydro light died yesterday on me, converting it to cree cobs.

The problem with Mars Hydro lights is they simply do NOT I repeat DO NOT honor warranty. I've already had a 700 go as well as a 1600 lost a row in the last few days so it'll be getting converted too...

Do a DIY it's a bit of a learning curve but well worth the effort, and you'll save so much on electricity it'll pay for itself compared to the crappy Mars Hydro...

PS. I've also found that a number of the lenses have simply melted away on the Mars Hydro 5W crappy epistartups... so much for quality
Greetings when your light went out ,mars wouldn't honor their warranty

Greetings how would (2) mars 900 watts leds work in a 6×4 area. I'll be growing using the scrog method.
