Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

thanks for the info.

40 reds on 60 would be perfect as i know ... around 66% is a well know and tested ratio used by most. 45/60 is the max to have a complete spectrum i think.

here i have a lighthouse hydro black star 135W UFO with 85% reds and only 2% white ..... and this light is doing really bad alone, maybe only usefull as a flowering booster for a HPS or else

Hi, Graytail! think in a positive way, you have already scored three pieces. Many growers miss the Old Model 100x3w, such a pity.

Wizgrow, I was watching the sale prices on the 'bay and picking them up as the price dropped. I got three and was working on the 4th when the listing ended and re-appeared with the 60x5s at 130 watts instead of 180. Rats! But at least I noticed the difference - the listing clearly says 60x5, but I might have assumed it was the same 300W old-style, too.

If you go back a few pages, Sara posted a few comments about the "new" old-style 300W panels. They're being driven at a really low wattage and aren't of a quality that Mars-Hydro wants to promote, so they're blowing them out. Until your post I didn't realize they were a different spectrum, but I've been keeping up with the newest Cree white COBs, and white is perfectly fine. They just aren't as PAR-efficient, because they emit a lot of unnecessary spectra.

So the only real downside to the 60x5s is inefficiency and, according to Sara, quality. The price is still a good value, I believe. I just wish I could have scored one more 100x3 before they sold out - I have one panel that doesn't resemble the others and it disturbs the feng shui, y'know?

mee too.

really like your place graytail

Hey Brother - long time!

I have not been on much since I started putting way more into growing and learning from the plants than web research and often times getting a lot of baloney

The Growing is going good too!

I actually posted quite few pages back on here somewhere asking about the Amazon lights and don't remember getting any feedback.....this was months ago and just got around to needing the 2 I got 3 weeks ago. That was why I contacted Sara directly via Skype.

Any case - it is what it is and I have gotten used to it with the LED companies - just as you have

Your set up looks good. One of my tents has a Mars 1200 centered and 4 100x3's in each corner of a 4x8. Pretty effective so far!

As far as the quality statement: Not sure what they are referencing that to. They look of the same construction and quality to me. I just don't like the spectrum and would have preferred the 3's watts and had them kept at 180 watt draw.

Soooo I think DSoM has it about right - going to order up some REDs. 4x 620 3x 660 - Can't hurt and Igro made me proficient at it

Ha, I guess the balck one disturbs the feng shui.

hi Graytail,
that is an XML350 in the middle, but what is one that disturbs your feng shui? what area do you cover with this setting?
respect

That's a DormGrow 240, for total of about 1000 watts in a 4x4.

for thoses that really really want a panel very similar as the OLD old model panel 100X3 ..... look for KingLED at amazon ... or bossledgrowlights on the web (they are the same)

they are using 100X3W and consume exactly the same (170W) as the marshydro OLD old model 300W

i have a 450W (150X3) from them and the spectrum is very similar (maybe exactly the same) as marshydro OLD old models, the unit is working good and the same quality as marshydro ... and their prices are very good too

the dimension are not 40cmX20cm as the marshydro OLD old model 100X3 .... they are 33cmX20cm as the new one

ONLY FOR THOSES THAT DEEPLY WANT A VERY SIMILAR UNIT as the OLD marshydro 100X3

bossled have some amazing lights with complete control too (dimming, spectrum control, timer, overheat protection etc) at amazing prices ... and many differents panel models (lenses, 10W chips, COB and more) .... just saying lol

personnaly i like them, but i prefer marshydro .... their service is not as good as marshydro and nothing can match the price of the new mars hydro old panel 60X5 ... they also dont have a warehouse in Canada and have to ship from china. maybe they have a USA warehouse, not sure.

they also dont have the reputation of mars hydro.

Hi pypcio, our recommendation distance is 24-30inches during germination, 18-24inches during veg and 12-18inches during flower.

Hi all,

I received Mars II 700w LED lights today, my seedlings are about 1 week old, from your experience what will be the best distance to keep the lights from them till flowering stage?

thanks for your help, CO Finest.

As high as you can get them for a week or so to get the plants use to the strong led lights then lower slow to you get about 24" and watch plants. If they dont stretch then leave them if you see any then lower about 3-4 inch at a time. Have not ever found the need to go lower then 18".

the distance is not fixed, watch the plant closely and prepare for adjustment.

Thanks man Now lights are around 2.5 feet above my seedlings (my tent is only 1 m x 1 m x 1.8m). I should get second pair of ratchets in next few days, then i will lift it up again.

JC Dozer, 1st time grow with led is full of twists and turns. Don't worry, you will grow better with exprecienced learnd. The temperature is a little high. Try hard to keep the temp done. could you take a pic when the light is off, it's easier to diagnose the cause of the bleaching.

Hi all, I'm doing my 1st all led grow with Mars led and have a got a few leaves with issues. Growing in hydro with plenty of nutes and cal mag additive ,nearly 3weeks in to 12/12. Tent is hot at 33 - 34 max temperature but there nothing I can do about that this time of year. Anyway, I believe that this is light bleaching aided by high temp. I'm just about to up lights by 8-10 inches but am already nearly 2ft above and asking anyone experienced with led if I am diagnosing this correctly??? Many thanks in advance.

haha, finally, it's not easy to spot one thing you are not good at, lol.

2 foot is enought to dont have bleaching from the light for sure .... look like nutrient deficiency more than bleaching at first sight .... and im very bad for it sorry

thanks, Celt.

Hello JC

Is there any chance you could take pictures just before LEDs come on or just after the LEDs go out . Problems are much easier to diagnose when the true colors can be seen.

if it's light burn, the color would be white, got it.

Light bleach aka burn with led will be white not yellow or brown. I can not tell what color in pic.

I have checked the item on Ebay and Amazon, from the name, they simply put 300w, not as clearly as 60x5w, if growers don't come to forums and follow the thread, they will tend to mistake it for the Old Model 100x3w. Even though the specification is written 60x5w, there is still possibility that some will neglect the info, but they don't intend to mislead people. Anyway, I will advise them to put it more specific like 300w(60x5w) in the name. And thanks for the reminding

Guessing this is not "Sara" as we spoke about these issues at length last night and can't see how she would respond to my post in such a manner.

Just my opinion but it might be helpful to stop referring to these lights as "the old model" ......they have NOTHING in common and it just leads people to making mistakes with expectations of what we are to receive -

And yes, I even spoke with Sara prior to ordering them with out have any of this info given to me.

hello, Dennise, 60x5w only has one fan, it's another difference.

WizGro... I have 2 of the old style 100x3w... just got one of them today... and I have one of the new 60x5 old style... I have been using the 100x3w to veg a couple of autos and will add the 60x5w when I go to flower and so far it is working fine... I have also used them for fill ins here and there.... Sara had said a ways back that they would not be selling them on their regular site anymore and only on ebay and amazon and that after all the 100x3w were gone all there would be is the 60x5w's and that they were not the quality they want on their site but needed a cheapo model to keep up with the fakes on ebay and such... The only major difference I can see is that the 5w only has one ffan but it seems to be fine and the wattage from the wall is not quite as high but again for the money... you can't go wrong IMO......

I appreciate it very much.

Hey Denise - long time

Not here to beat up on MH...... Sara and I spoke last night and she recognized her mistake in telling me they were the same light. I ordered before the release of the info back on 6/11 but just put them into play. I am to just make due with what I got and fix them myself. As for the new spectrum and all the white: Been there already with a mistake on my Igro/CTlites. Still no expert but gaining some competence after a year now with 4 flower tents .......and getting a sense "Of what works" - and can only say that swapping out alot of white to the more reds that should have been there originally gained and sustained over 20% more yield -

So no bashing - just going to make the changes and update if there are any replacement issues for others in the same predicament as myself

awesome grow! they give me a good appetite, lunch time here.

received a 96x5w reflector yesterday its not their top line but it is great for me
they try to please many different needs. poor folks like me
all the way up to top notch like the people who will get the new cree to test
i know mars is not perfect but they are active and constantly try to improve
no business ever had a perfect rating
just being here so long should give some idea that it is not fly by night
i know it is not always sara and also that language differences still cause some problems
and many of the mishaps are totally real and would frustrate anyone
just try to be civil and believe that they want to make money and thus need to please us
all of us

what i did with my mars stuff...

 

[Mars Hydro]

to be honest, yuyo, you are very frank, haha, but I like it. Have being here for two years and experienced various accidents, I have to say, you guys are really tough, lol, anyway, we have survived and will not vanish overnight. We will try to achieve the best customer satisfaction. very good result.

Hi Sara,

We have spoken over my email recently so I have come and joined 420 rather than just lurk in the background. My old HPS ballast has given up and died so after all I have read and the growing space I have I want to go over to LED. Could you and the other experienced led growers give me some advice please?

My set up is - a standard size wardrobe as it's more covert than a tent. Fully reflective interior. I have an intake fan, 6" interior rotational fan for air movement and a rhino carbon filter/fan for extraction. I only grow max 2 plants but they are often a good size. I grow in coco.

My question is - do I buy a Mars hydro II 400w for veg now and buy a second 400 so I have one over each plant in flower? OR

Do I but the 144x5 reflector now which will run the whole length of my narrow grow space?

Plants are main lined, topped and trained to grow bushy and narrow within my grow space.

Any advice on the above is much appreciated Sara and all.

 

[DarkSidofMike]

we need to know your space area and dimensions to give you advices dopey

im growing in my wardrobe me too and i have 2 differents area in the same wardrobe .... 58cmX85cm and using 2 panels old model 300W for veg and flowering ..... and another area of 58cmX58cm and using 1 panel mars2 400W for veg and flowering ... no official intake for both and only 1 or 2 90cfm 120mm pc fan each as extractor .... having amazing results with mars hydro

you will need a speed controller for your extractor, cause you will need to step it down if you was using HPS before in that area ... LEDs produce very low heat

so give us your area dimensions ..... and will help you

 

[Dopey Bob]

Hi Mike,

Thanks for stepping in to help. I've gone and measured up and thankfully I did as I would be too short at for the 144x5.

Fairly close measurements to be safe and give a little bit of elbow room would be 53 x 82 x 180 cm interior space.

Yep, I have the fan controllers

 

[DarkSidofMike]

ok ... so i think your best options are .... 2 pcs of "new" old model 300W (60X5) will be very good for that area, and for real cheap .... 1 pcs 96X5 new reflector (not the old 96X3) will be very nice too, but for little more money (or 2 pcs 48X5 reflector) .... and finally 1 pcs mars2 400W will be good too, for little more money again.

my best choice are .... 2 old models 300W for the very good price and nice light distribution with 2 panels .... or 2 reflectors 48X5 for better quality panels and very nice light distribution too with 2 panels

happy growing

I am leaning towards the 400 mars II. I can easily control the heat now I am stepping down from HPS.
On the mars hydro website it is only given the 144 as 5w not the 96. So I would need confirmation I can get that panel in 5w but it would give a good spread of light.

My current thinking is perhaps the 400 and that would still leave me enough room to add another panel of some kind if I wanted to add more light. Again I am open to feedback

 

[DarkSidofMike]

yes, maybe you can add a little UFO 180W later, if you think you need more light

you will love marshydro LEDs no doubts ... HPS are from another age

 

[Dopey Bob]

HPS are from another age

So am I Mike lmao

I believe Sara said that all of the warehouses in US and Europe have the updated 5w panels.

 

[DarkSidofMike]

hehe

 

[Dopey Bob]

Yeah Sara said the 144 was in stock in 5w but I didn't ask about the smaller panels so am I sure she will pop by to confirm. Luckily I measured before ordering the 144 as that would have been a real pain.

I could fit a 700 mars in that space but I'm concerned with that headroom it could be overkill. But from what I have read in this thread it's advised 50w per square foot. Basing that on actual wattage the 700 is about 300ish watt output right? So my space is roughly 2ftx3ft which would make 50w per sft. I appreciate that's approximate.
