Mars-Hydro LED Grow Light Discussion

Wow, great, thanks for this instruction, Eagle, it's so thorough. :adore: I have read it through. It seems not that difficult.:) first I need to strengthen my confidence. My hand is very clumsy.:bigblush: maybe I have a try:cheesygrinsmiley:

Hi Smith, I am sorry for this. Another 50 leds are not working. :volcano-smiley::thedoubletake:It's a serious problem.:trance: We will send you the parts. If you don't mind, you can send the light to our service center. I will contact you again. We can work it out.:high-five:

Hi All,
I would like to tell everyone about my recent experience with Mars Hydro and a warranty issue I had about 2 months ago.
Early last year I bought a M2 700 for my first indoor grow, all went well, and I packed it away for the summer. So in June I set back up, and again all was well. About the start of June I happened to notice that a bank of 25 LEDs was no longer functioning so I contacted Sara to start a warranty claim. She was very fast in her reply, requesting pictures of the fault and all the relevant details, she then forwarded my case to Sean who took over from there, confirming all the details and requesting pictures, 2 days later, and everything was sorted and a medium sized envelope with all my new parts was on its way by China post. Everything arrived safe and sound 4 business days later, to be honest, I was astounded, as I had shipped things from China before by China post and waited up to 2 months for it to arrive, definately a new delivery record as far I was concerned, anyway I digress. Because I am in the middle of something at the moment, I didn't do the repairs immediately. Tonight I noticed another 50 LEDs not working, so apparently fate had decided I was doing the repairs tonight, and so 2 hours ago, I unhooked the light, turned the solering iron on, stuck 2 AA batteries together for testing and grabbed my number 2 phillips head screwdriver. I am happy to say that not only is the build quality of the light very high for its price point, but the replacement of what turned out to be 4 warm white LEDs and one diode was one of the easiest repairs I have ever made to anything, seriously, anybody with basic skills could do it unassisted. Unfortunately, because I am clumsy, and reckless, I melted the lenses on 1 blue LED and 3 red ones which then also needed replacing, but, you know, shit happens.
Anyway, all went well (although I no longer have any spare white LEDS because I was only supplied for the original repair) and I would like to thank both Sara and Sean for their exemplary customer service, Mars Hydro is definately a standout Chinese supplier, and if this level of service and quality continue they will be a majar player for some time.
So, in the words of the legendary Denise "I love my Mars Hyro lights, and I am a real person".

:thumb:haha, randy, thanks for the explanation in practical perspective. :Namaste: I have searched a lot and find out most of them support the red and blue together. However, I haven't found the comparision expriement for blue only and blue&red. It's been a long time since I went on a research. To be continuted. :high-five:

There were questions about the grow bloom switches on the lights and what they do and today I spoke with a friend who is a long time grower and regularly attends class on the science of growing all plants not just MJ his comment was the blue spectrum promotes the stem,branch, and leaf growth and is great for young plants but the red spectrum develops the plants ability to change over to flower and if it is either not given or held till the plants are well into the growth cycle will cause the plant to have a reduced flower output and development. He recommended only using predominate blue for the first week or two (I know he uses clones so longer for seeds)then a full spectrum or at least a mix till near flower then only full spectrum, predominate red from there on. Hope this helps those who have wondered about the switches and it will be interesting to hear what Sara finds out

I spent an hour listening to the explanation and felt like I was in school again and after forty years it still gets boring so at your age research should be easy (you tell Lucy to do it):idea:
 
Just found this about blue light and plants


Blue photons do have one very important feature though, and that is they inhibit auxin synthesis. Auxin is a plant hormone that causes elongation, so if you don't want stretchy plants, some blue wavelength light is a must. An important caveat is that auxin and its blue-wavelength-reactive buddies are important for flowering, which is why it makes sense for people switch to a "warmer" color spectrum during flower. The increase in auxin and the decrease in light from switching to 12/12 both explain why a plant grows 2X to 3X in height during the first few weeks of flower.
 
Haha randy, I will try. Although I am not confident in cooking, I do have confidence in sefl-learning. Wait for the result, next Monday.:high-five:

Hi Sara,
I have repaired the light and put it back into service, so it's no problem.
Having given it some thought, I would like to make a suggestion concerning the LED service kits you send out for repairs to your lights.

In your kits, you supply the whole series of LEDs required to service the faulty area, they are all packed into individual packets and labelled, what would be helpful is if you could supply a location map, although the LEDs are labelled, their position or location on the light is not, with the whites it isn't an issue because they are noticeably different, but with the reds and blues, I for one couldn't tell them apart. Also, some heatsink paste would be a good addition.
In regard to supplying me with some more LEDs that would be awesome as I depleted my stock of both types of white and a couple of blues and reds, the amount of diodes you supply with the kit is more than generous.
Please feel free to contact me directly through email to clarify anything.
My original order number was 100001027, you should be able to get my details from that.
Thanks,
Blacksmith.

:yahoo:great to know you find one! That couldn't be better.:cheesygrinsmiley: you can open a grow journal or share here the grow. I'd love to see how it works!:goof:
Right now, we still have 48x3w in Canada. Apart from that, yes, Reflector 48x5w is the smallest light we have. :Namaste:

Thanks sara I do have a journal going with my 60×5 light the link is in my signature First Grow - Blue Treacle Auto - Mars Hydro 130W LED - Coco Early days at the moment so not much to see as its mostly seedlings at the moment. The 48×3 reflector on the other hand will probably stay in stralth mode and not be on this page as its not mine. But it arrived safely yesterday and appears to be working fine
 
Hi Sara,
Just wanted to let you know that one of the Reflector Series panels that I ordered recently has now made it's debut into the Ganja Grove.

I've switched my lights on time to evening hours to accommodate for the additional watts/heat from the addition of the Reflector but all is working out good so far.
Ambient room temp/RH is being maintained at about 68 to 72 degrees @ 50% RH through the use of an in room air conditioner.
Environmental conditions inside of my tent are averaging about 77 to 79 degrees F at 50% RH with lights on. Life is good! :)

Awesome idea!! Reps++

You should also post this in the grow room threads.

Just try it and do not worry about your mistakes. Mistakes are chances to learn what does or does not work. Due to a mistake the antibiotic penicillin was discovered. The light bulb never would have been invented if it were not for mistakes.
