Mars-Hydro LED Grow Light Discussion

Hi Sara I've just taken some LUX readings of both your Mars II 1600w and your Reflector series 96x3's. I'm not sure if you deliberately downplay the lumen output of these lights (especially the Mars II 1600w) as part of a marketing ploy, so that every customer is happier than they expected but let me tell you that I was pleasantly surprised! If you would like to check out my results and have anything you would like to add please feel free to drop into my Plushberry clones grow in my signature and check it out.

All the best everyone, have a great weekend :thumb:
 
Ok party people, we've finally had a chance to sit down and open these problem fixtures up. I'm really happy with everything I've found too!

You can see that the relfectors are being held up with not a stud, but a plastic screw and nut. While this sounds like a great way to fasten them, they obviously loosen up in shipment. All of the lenses I have drooping or falling off are missing the nuts and/or the studs!

Normally I would think this was an acceptable fastening and prefer it, but I have to say, a bare stud with a spring steel nut would probably be more cost effective as well as handle shipping better. A simple fix!


Sara, I'll follow this up with an email, but if you could just ship me a bag of studs and nuts, I can fix this pretty quick :high-five:

As far as the rest of the fixture goes, I'm very impressed with the build quality. Almost too much so! It's not easy to separate the back panel from the front because of the cabling. The three that go from the drivers to the boards do have quick disconnects (code required, but still nice to see) but for security, they each have a ty-wrap holding them together, nice touch!

So far, she's loving the light, I can't wait to get the other hanging up there too!


Healthy green all,

Have to install fans, intake,make scrognet and finish doors, than growroom is ready :)

Looking like a sweet setup there ganjazz, clean and discreet. You might want to consider making a journal so that other people can join you in your grow. All the best :thumb:

That sounds truly strange, because my 48*3W is 1-8cm from the canopy and there is no sign of bleaching, even at the bud site that is almost touching the light. I veg'd for 35 days, so this little monster of a plant (indica) took over the whole 40x40x120cm space and there is simply no more room to lift the light any higher. Luckily it doesn't seem to matter much because the plant is very happy and the reflector isn't nearly hot enough to cause any burns.

The main point of my post is to give Sara, the lux reading within my particular grow space.

Just for the sake of giving more information about my particular grow space:
Wall material/color: Dry Wall/ Matte white
Temperature: 25 degrees Celsius (with light on and both switches flipped to the on position)
Humidity: 50-55%

Grow medium: Humus soil mixed with compost
Container: 11.4L Smart Pot
Nutrients: Bio-Canna and additional molasses.
Water: Single pass carbon filtered tap water
 
Hey Sara!
Ive read a good deal of posts about different LED lights and I am leaning towards getting a MarsII, I do have a couple questions if you dont mind.
I have a fairly small grow tent, 36"x36"x72". Could you tell me if I would be better off with a MarsII, or a Mars reflector unit. I have read that the MarsII will produce slightly more heat than the reflector unit does. But, I am not really worried about heat being an issue as I have a decent ventilation exhaust system.

IF you think the MarsII would be better for me, would you recommend the 400w unit or the 700w for the size space I have.
I dont mind investing more in a unit if it is a good one.
really I appreciate any info you can give me!

I have a 900 in my flower tent and 2 400's in my veg tent. :peace:

how big is your veg tent? you may have already seen my other post, but what do you think about the Mars reflector144x5w its less expensive than the MarsII700w and has more wattage, as well as the added bonus of veg and flower switch(which i think is cool:) )

Consdering that your tent is 9 feet (3x3) and going by the 45-50w/square foot rule, i would say you need the 700w mars hydro minimum. I believe a 900w Mars hydro (consuming ~450w real watts) would be great.

I have 2 Mars-Hydro 3x3x6 tents side by side. Feel free to look in my links at the bottom of my signature. :peace:

Hey friends,
I have almost the same question. Except my tent is 1.5 feet X 2.5 feet (30x18in). I have almost got myself a Mars II 400W then looking at the reflector series I have to wonder.
I would like to keep the heat down. I currently have 2-250Watt CFL (one red and one blue). So I am very eager to get a LED.
My biggest concern is keeping the price below 250usd.
Cheerz all.

If I were you I might consider the 96x3 reflector. The coverage are might be better suited to your grow area. :peace:
 
I read that the 96x5 maybe available now i'm waiting on them bad boys. On the mars site it says to unplug during rainy days which would be impossible here as there is a chance almost everyday here during the summer. Should you run a voltage stabilizer? They seem kind of pricey could just buy a new light with the price of some of these things.

I'm not too sure about the 96x5's as they're not over here as of yet but I'm running 2x 96x3's and I never need to pull the plug on them when it's raining. I think it's more a case of if your house gets struck by lightning or something like that. I use power surge strips anyway, they're cheap at a fiver a throw and will (hopefully) be enough to stop any external power surges. I think maybe unplugging them is just over cautious. All the best :thumb:
 
I see most people hang their led lights rather high above their plants, why is that?

Since they dont produce mush heat, distance i use is max 15 cm with good results.

-------------------

Waiting for mars2 700w to be shipped tomorrow, :tommy: :slide:
Than everything is set and ready :yummy:

For grow gonna use 700w and for bloom combine with reflector 300w= +500w HPS :)
Want to take good care of the ladies ;)

:ganjamon:
