Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

this light has two switch. 192led. 120led under growth switch, 72led under bloom switch. growth switches control red,blue and white. bloom switch control red and IR. if you want, you can use both switches at whole stage but not only growth or bloom. but we suggest customer use growth switch when plants grow, and turn both switches on when the plants begin to flowering.

Sara

Thank you and thanks for the link. Much as I wanted to be surprised to see what you sent, I clicked on the link. It shows that panel setup for veg and bloom. Will the panel do both or if not is it set up for bloom or veg?

 

[Mars Hydro]

Hi Techman, wow, it seems you sent inquiry from alibaba to us. I will PM you some information to tell your our relationship with that company. thank you for telling everyone reflector light is good. and we know it, that is why our COB light design base on reflector light.

ok, I posted my pics in the Gallery. - Please, no comments on the white spots - It's drywall dust

Top LED Brand or not it is the same exact technology. There are two companies making the reflector style light. I spoke with both company reps and for my own reasons, chose their competitor. I'm not trying to promote anyone's brand just providing some FYI on this style of Chinese Lights which I thin work very well.

 

[Mars Hydro]

simple way to count LED replace hps: LED max power= hps wattage you should replace. such as our 324x3w=972w, and you can use it to replace a 1000w hps.

we suggest our customer hang the light above plants 60cm~100cm(2~3feet), but the high power light, we suggest customer hang above the plants 100cm(3.3feet) at least. if the light is too strong, it will make the plants burnt. hang higher, coverage will be bigger. becuase we have LED use 120degree lens.

apparently the lights im looking into getting claim to be 1000W replacers and they have the plants to prove it. i dont know if i can or should post the name here. i could just pm you.

 

[Mars Hydro]

yes Buck, you are right. 240x3w, they can drive to around 400w, it is impossible to replace 1000w, and the reflector light looks weak because the distance between each led is larger than other light. but it has higher lumens output.

You need to look at how many watts the panel draws. If it draws say 400 watts there is no way it can replace a 1000 watt HPS...

 

[BigIrishDoode]

this is why i havnt spent £4-500 on a single led panel dunno what shit your buying, all you see is this is "the best led panel on the market works better than hid" this is why im selling it for practically nothing a month after buying it

huh? im not buying anything at this time,im testing a light for sara & her company, & even if its not a spot on replacment for my 400 or 600watt hids i would think it could be a great supplemental tool,im not one to blindly believe the hype these different companys say, i never impluse buy,$$ is in to short a supply in my world to let go of easily, hell i hold on to a quarter so hard when i do let go theres a smear of eagle poop in my palm!

Bid
It could be that ppl are reselling Sara's light or could be that Sara simply buy in bulk and are reselling themselves as there own

yup thats what i deduced from it,just waiting on sara to say which.

Wow, your just now finding this out. Hmm......

well yeah its not like i have spent much time blindly googin' random led panels, i started researching the particular light im getting as soon as i knew what light it was, see i looked into led growlights a couple years ago,enough to know that the ones i could afford were not any good,i left it there and occasionally go look at flea bay to check prices, waiting for good lights to drop in expense to a point i could manage, had i reached a point where i was ready to get one i would research it and scan for reviews, so i guess you could say i have not been keeping up with the whole led market, make more sense to you now, what i've been consumed with is study on breeding,high brix,and high cbd info,

too much bullshit when it comes to led, tbh cant really trust anybody, proof will be in the grow outs, but even then is it gonna be the same panels were buying or is this the decent ones being shipped to you guys and we all see decent results then buy shit.

i was thinking exactly what jon705 says below, this is a big community scammers dont last long here,they get exposed and word gets around quick!

Sara works for a manufacturer,people are rebranding and reselling her lights.


Come on bro, do you really think a company is going to pay $2000 a year to become sponsors here just to have us expose them as frauds once they sell a few lights that are different than the testers we are getting?doesnt make much sense does it? Maybe these lights arent where they need to be yet but by giving a few away to experienced growers and asking for honest feedback on what needs to be changed I think Sara honestly wants to make a good product that is affordable for everyone, I believe that led grow lights are the way of the future for indoor growing, its just a matter of dialing in the right spectrums and angles, once they figure that out being a big manufacturer and being able to buy all the parts in bulk will mean quality lights for a fair price for all of us

I agree i think sara means well and wants to produce quality lights and offer them at an affordable price and make up the profits in volume vs markup,being a sponsor here is not some small thing like throwing up a flea bay auction, we influence alot of growers and doing well here can mean a major boost to the bottom line of any company,,also you will make far more $$$ being a good sponsor,than a scammer that makes a little then is ousted for suckin'!
thats my 2 cents anyway

 

[Mars Hydro]

agree .

It is not that simple. The LED diodes have to have a lens to be effective. This lens by default limits the growing area. I like Jon's vision, it will be awesome!!!

 

[Mars Hydro]

Hi BID, I can not check the link, please E-mail me, thank you. my E-mail is : sales@topledgrowlight.com

If their price is lower than ours or they have big discount, I do not think it is our customers. we are factory. no matter how many lights you order. we can not give too much discount, because our profit is limited.we need to run our company well, and we have a long way to go.

Besides, I will not tell others who is our retail customers, because we need to protect our customers. you can judge/guess yourself, I keep silent. Hope all people can understand this

hey sara check this out, i found tons of listings and different sellers of the mars II light 80x5watt (400watt equal its claiming) heres a link to it "link", now are ppl reselling your light,or whats this situation, i thought you should know,the prices are all over the place as low as 100 usd if you buy 5, specs are the same, i just did a search for the "mars II led growlight" even uses the same pics as on your site

 

[Mars Hydro]

We are the real factory. you can not find the same size and same specs light with ours in China, we do not sell our lights to any trading company in China.

A Trading company, their delivery time will be very long,one week at least. becuase they need to order your lights from their supplier after you pay them. here has very very less trading company who can stock LED grow light, even most factory can not stock lights. LED is expensive, they will cost hundreds thousand USD on stock. most company do not have money to stock.

Bid
It could be that ppl are reselling Sara's light or could be that Sara simply buy in bulk and are reselling themselves as there own

 

[Mars Hydro]

Hi Jon, thank you, yes, that is what I am planing.

Come on bro, do you really think a company is going to pay $2000 a year to become sponsors here just to have us expose them as frauds once they sell a few lights that are different than the testers we are getting?doesnt make much sense does it?

Greetings Sara

i took this from the Area 51 forum

here is their take on LEDs and spectrums

--------------------------------------------------------------------------------------------------------------------------
"I'm sure many of you have seen many 1-2 red and 1-2 blue 90w UFO's compared to 400w HPS grow lights.

How did they come up with these numbers?

It's simple, per the popular belief, and misconception, "plants only absorb blue and red, everything else is wasted". If you look at the PAR of a typical 90w UFO with 440nm, 460nm, 630nm, and 660nm, you're looking at roughly 300 Umol'/s at 12", or less.

If you took a 400w HPS and removed everything besides the same spectrums as the UFO, you'd have roughly 100 Umol'/s.

But if it were true that plants only used red and blue, why doesn't a 90w UFO even compete with a 150w HPS? It's because there's more to spectrum than just red and blue, plants absorb everything in the visible spectrum and somewhat beyond, though the absorption rates are different from color to color. We believe (most) plants will prefer a spectrum and intensity similar to this:

400-440nm 15 Umol'/s
440-480nm 65 Umol'/s
480-520nm 65 Umol'/s
520-560nm 160 Umol'/s
560-600nm 160 Umol'/s
600-640nm 240 Umol'/s
640-680nm 65 Umol'/s
680-720nm 15 Umol'/s
720-760nm 15 Umol'/s

The spectrum and intensity levels should stay the same except for lesser red and yellow in veg. Basically, you'll have 800 Umol'/s during flowering, and 500 Umol'/s in veg.

Plants have been growing under a full spectrum Sun for millions of years. And they've been growing indoors for decades under full spectrum fluoros and HPS/MH lamps. Full spectrum is what they're used to.

And since we started building our LED Grow Lights with the primary color as white, plants have been growing faster, happier, and bigger.

Even though plants prefer a full white spectrum with the red 600-640nm favored, they can and will strive under other colors as well, or lack thereof. They'll just do better with the white."
--------------------------------------------------------------------------------------------------------------------------

Sara could you please post the spectrum's and Umol'/s at a their recommended distance from the canopy, total Umol'/s for each test light at recommended distance and light penetration as well that your vegetative and flowering lights use that will be sent out for the test grow journals.

have a good day

Sara could you please respond to this

 

[Mars Hydro]

Hope this picture can help a bit, I will explain later, I have something need to be done now.

 

[Mars Hydro]

the picture I upload was maken by my friend who is also a led grow light seller. she likes making this data, but we did not make ourself. this umol will be affected by the lens of led chip. before we make 100degree for her, the umol is very low, while we make 90degree for her, the umol change a lot. from this experience, we'd like to tell customer lumens but not umol.

 

[KingJohnC]

can you give the figures in lumens then please?

 

[Mars Hydro]

sure, I will make one picture with lumens tomorrow. today I have no time to make it. sorry.

 

[TaylorMade420]

sorry guys i read back my comments from last night and seemed like a bit of a dick, im glad that some1 is actually working with the community to produce thes lights, i have been tempted before to buy leds just never had the balls to actuallly go through with it simply because ive had no confidence in them, if i had i would probably just have been another idiot who bought an led panel for a few hundred pounds selling it for sfa on ebay lol.

 

[Buckshot]

For all you folks following this is about to turn from talking to growing. BID has never grown with LED and is in for a big surprise So I thought Jon and I could fill him in in public so everyone following can benefit. Here are some things I learned...

Less water
overall less nutrients... but
More cal/mag
plant structure will be different, wider leaves even on sativas
plant leaf and stem exposed to light will become purple... this is not a deficiency
I don't know about 5 watt LEDs but for 3 watts you can get pretty close without burning.

Jon you have anything else?

 

[jon705]

I think different lights will have different requirements bro, My lights have 3 watt chips and I try to keep them at least 24 inches away, manufacturers rec is 28 inches during flower, I find with led's the closer you get them the smaller and more intense the footprint and I let my plants dry right out almost to the point of wilting before I fully saturate them,
Plant structure is definetly different, shorter stalkier with much tighter node spacing,
I agree with the red stems, for the longest time I thought I was doing something wrong lol
I think plants under led's finish up to a week faster and the nugs will be alot denser and frostier than hps,
Alot of led growers say to run the room a bit warmer with led's but I tried that and dont agree, im running my room at around 75 degrees this round and the girls look better than ever,
Watch out for bleaching if you have the light too close,another sign the lights are to close is the pistils will curl away from the intense light instead of standing straight,
thats all I can think of right now

Techman Does.....

I'm watering every 8-10 days - Easy on the Nutes.
Yes more cal/mag.(Too expensive) Instead I use lime in the soil at transplant and Epsom Salt at watering. I add molasses every so often too.
The Grow room can be warmer. - 76-84 is where mine is running
Purple leaves/stems? - Some but not all my strains do it.
Nice big fan leaves - Yes
Plant Structure - Yes, I think it brings out different traits in the plants as some strains look quite different now.
De-foliage to help light penetrate to lower branches
Keep light close to prevent stretching

*What looks finished under the LED will not look finished under regular light. Same for deficiencies, check under regular light.

Good Luck, I'll be tagging along

 

[jon705]

I judge wether they're done or not with a 100x scope with a white led in it bro, doesnt matter what light they are under when you use one, the trychs dont lie.I ve grown my cut of PK under both hps and led, they finished a week faster under the led's everytime. every grower has his or her own way of doing things, There is no one right way to do it, BID is an exellent grower I think he will end up coming up with his own way to do things, room conditions probably play a big part in all of this too, THe guy that designed my lights has done extensive test grows growing Marijuanna, and with his lights his best results were with cooler temps during flower in the 72-75 degree range and instead of defoliating he suggested cleaning up the bottom but instead of defoliating to spread the plant out to get the light down into the plants, he and alot of other growers swear that each healthy leaf plays a part,so thats what im trying this round and so far im very happy with the results but im still early in flower.Ive always been a"gotta try it myself"kinda guy, I feel its the only way to figure out what works best

 

[Buckshot]

Purple leaves/stems? - Some but not all my strains do it.

De-foliage to help light penetrate to lower branches

I read back and it did read like "leaves". What I meant is the leaf stems and if you LST the plant stems will become purple where exposed to LED light. I have not had a strain that did not do this to some extent. Since BID might use a "known" strain I thought I would warn him so he did not try to compensate for a problem that was not really there.

Oh no a defoliator ...
