Mars-Hydro LED Grow Light Discussion

KingSativa said:
The new Mars has a different set of LEDs then the one I bought 6 months ago. The new one is much brighter in the red spectrum, or the other ones have just faded. It is likely the red LEDs are just fading from use. I am excited to see how the Cree XP-E2 red LEDs look after I install them.

The two in the back are 6 month old Mars II 400 watt panels, the one on the front right is the new Mars II 400 and the one on the front left is a 6 month old Mars II 700 watt panel. So compare the 400 watt panels and you will see a huge difference.

Sara, are the old LEDs just getting old or are the new LEDs just a different style from Epistar?

The photo doesn't show it as well as in person, but if you look at the front right plant you can see it has much stronger and more red light shining on it compared to the other 3 plants.

Why are you using so much light/power on those 4 small plants? Save yourself, some of that hard earned money. You could probably just use the 700w, or two of the 400w until you are ready to flower them.
 
I have two of the 300w 60x5 working in my 2x4 flower space they work well. I paid 134.00us for the pair from Ebay in august.they are 143.00 w/free shipping now.

I just transplanted into 10 gal smart pots, so they are really far apart and hard to cover with lights. But more importantly I am crushing them with light to keep them short and to build huge root balls. These are pure Sativas and I am vegging them for a solid 8 weeks. So if I don't keep up with them they will quickly become monsters. So I tried to FIM them and will LST the hell out of them till they are nothing more than a flat mat of green (I call it MOG) I actually missed the FIM on three and didn't cut enough off, and cut to much off on the fourth plant and topped it).

But they are super healthy and love the huge pots of organic soil and super amounts of lights, so I figure I will just run them full throttle from seed to flower.

Keep them

How much light are you bathing them in they look very good !! It will be fun to see the journey to curing. :thumb:
 
I have 6 Mar II 1200 they work great for growing the only problem is they don't last all 6 of mine have 10 to 16 burned bulbs. the guarantee suck they send you parts say its easy to repair not the case. send you video to watch how to fix can not even understand because audio is so bad. I would never buy again. Cheap price cheap light. BTW i have been growing with Leds for 7 years now and have had better luck with hydroponic hut pg550 had these lights for 6 years and still using them to this day and much better warranty service Mars Hydro warranty service sucks.
 
I have 5 1200w models , 4 that are a couple years old , 2 of those 4 have burned out LEDs and the reds are different. Just last night 2 more diodes burned out . It does happen , I don't even ask for parts , just do it myself, I bought cheap lights a while back and use them for parts , when enough LEDs burn out I just open them up and put new ones in .
 
I don't know if any of mine are burned out yet. A few look dim, but I think they are the IR LEDs as they are symmetrically positioned from each other. But I would not put Epistar LEDs back in at any rate. If a power supply died I would ask that it be warrenteed, but I am replacing any burned out LEDs with Cree XP-E2 top bin LED. I have 20 of them that arrived in the mail today, 5 blue, 5 warm white, 5 630nm red, and 5 670nm red. I will pull down one of the old units here in the next few weeks and swap out these for 20 Epistars on one of the panels. Hopefully all goes well and I add some efficiently and some more light. :).

It is not cheap though. The reds are about $2.75 each and the blues are about $1.75. So swapping out 80 LED gets expensive quick.
 
is 36 inches distance from my Mars 2 900 light to the soil in my solo cups a good distance for seedlings just breaking the surface? I am wondering if it may be a bit too far but i don't want to burn them
