Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

Morning Doobzilla, yes, you don't need two at this time. One is enough for them. Hold the surprise for your babies for a while, they will love it.

Hello and Good Morning or Evening wherever you are! I am back with another question for you all..

So far the ladies are off and running, I am happy with the start.
I am running (2) Mars 300 watt lamps on my seedlings there are three total the two white widow are 9 days old and I have a bubblegum strain that is 6 days old, very young. Do I need both lamps on my ladies so soon? Can I go with one LED for the rest of the veg cycle and then add the second for flower? I have heard a comment or two saying I may not need both right now, just wanted some more input on that. I'm thinking as long as taking one away won't affect the coverage of three pots (one is in a solo cup right now)then I will do that for now until I add more ventilation.

hello, Fiete, how does your light work?

Yes only 1 Light are enough in the First 5 weeks i think...

uncle is here, problem solved.

IMHO you should only use one for veg and wouldn't need to use the second lamp until around the beginning of the 2nd week of 12/12.

 

[Mars Hydro]

absolutely right, have a go!

so if I order a 196x3w reflector I will be getting a 196x5w instead?

 

[Mars Hydro]

Yes, we will ship from China to New Zealand.

Sara, do you ship to New Zealand?

This grower is shopping for a panel.

Which of these LED lights? Need help fast

 

[Mars Hydro]

hi Fiete, the website will be updated next month after all the warehouses are stocked with Reflector 5w leds. Either 3w or 5w has its own advantages. It's up to your preference. 5w has better penetration while 3w will produce less heat. Reflector 96x5w is available in EU, US and Australia now.
Fiete, here you will also find many growers have good result from MarsII.

Thx Sarah! On your Website MarsHydro.com are the 3 Watt availeble only on eBay the 5 Watt! Is that not true 3 Watt Chips are better than 5 Watt Chips?

Some pepole say the Mars LED are Shit and only beginners of growing like the..... Any Grow Reports here from the Reflector ore Mars 2??? Please links please so i can see... I saw some Page bevor a Damm huge plant under the Reflector incredible Growth with the Reflector but i never See buds from the Mars LED!

On eBay are the 5 Watt Reflector are availevle 96x5 i think?

the grow rocks.

Feel free to look at the links in my signature. They are all under Mars lights and in Mars tents.

 

[Mars Hydro]

the Old Model 300w is 60x5w, it will work great with the 144X5w

Yes, the stretch over the past 10 days has been incredible and I'm trying not to do anything but LST to tame.

Rotating the 144x5w tonight, think I'll order old style 300w for now vs the 48x3's.

 

[Mars Hydro]

very nice grow, it will be a good harvest.

This plant along with 4 others were grown under 2x96x3 reflectors +1 180W UFO nice dense crystal covered goodness

Hello Sarah,

Satisfied with grow progress, girls looking very good,

Sometimes since a week,the reflector 96 x 3w makes a rattling sound(fan).

What would you advice to do.
Should i open and check myself , or replace fan?

Ow, and the mars2 700w is an absolute beast, the ladys her.

@SmokeSara: 60 x5w
"I suppose the most common problem it will have may be leds, as long as you change them, it will be OK, "

Is it easy to replace and find those leds in case of....?

And the 96 x 5w reflector is available in uk you say, if so im considering to order one more.

 

[Mars Hydro]

WOW, it's very thorough. Well Done! this may be a good reference for our light improvement in the future.

hey growers,

maybe as me you are not sure how many PAR/PPFD or umol marijuana need for flowering .... i found this usefull info on a very large number of pants, including "canabis sativa" on the last category at the end .... this category is for full light plants, so make sense

each plant catefory have his own "DLI" for Daily light integral and how many PAR/PPFD in umol each plant need in a total day. as we see, flowering at 18h or 24h a day need less light power .... make sense too (great for autoflower seeds)

PAR quantum meters are giving this number in umol. PAR and PPFD is the same as i know and mean umol beetween 400nm-700nm only (blue to red), so light usable for plants only.

it's under preparation, I am also very curious to know.

Very important to say, to see this even more clear:

If flowering time is 12 hours, your plant needs minimum 510 uMol per m2 per second.

Thanks for sharing Mike!

Sara, when will MarsHydro carry out a PAR measure?

icemud did a great PAR test with the Mars2 400W (80X5) .... you can see it there ...

well said.

so to be clear me too ... it mean you need minimum 500 umol (700 is better) EVERYWHERE in your garden to have full power light and optimal results with cannabis.

if you use only 1 panel for a big area, the edge of the garden will not have 500 umol and will produce less. that why many smaller panels are better than only 1 big.

would be nice if icemud did the test to 1 foot each side, not only 6 inchs.

Hi DarkSidofMike, thanks for the info about the competitor, it doesn't matter what he says. At least, now I know how hot our LED sales is on Ebay. I wonder how come he will test the light loss after 1 year, our 60x5w has been for sale only for about two months.
the Old Model 60x5w is just not as good as our MarsII and Reflector series, in regards to materials used, design and spectrum. Althoug it only has one fan, the Old Model 60x5w also adds heat sink to help dissipate the heat. As for the light loss, there is no exact data for every LED light will lose certain light after a certain of time.

hello Sara,

one of your competitor on amazon compare their 300W panel to your NEW old model 300W (60X5) ....

they are CLEARLY talking about your product and this is what they say .... "poor heat dissipation, high working temperature, huge damage to the chips, short lifetime. Large light loss, 70% light remained after aging of half one year, 50% light remained after one year."

i know it maybe only competition tactics or something like that ... but please i need to know what is the light depreciation or light loss % of this product (300W 60X5) after 1 year.

you said this product use lower quality heat dissipation, chips, housing and more ... specially for heat dissipation, it seem to be a bad idea to go for low quality. the lifetime and brightness of the chips are very important.

so please, tell me more about this product (new old model 300W 60X5) and specially light loss % after 1 year ...


tyvm Sara

facts speak louder than words, randy, I like the way you have everything under control.

Mike if you look through the old posts I don't think the 60 X 5 lights have even been out more than a few months so how do we know what they will do in a year ? I have found truth in advertising and eBay are words that don't get used together often as for temps the best answer is a temp reading of both lights in the same environment in my tent the 60 x 5 was 106 - 112 f on face the Mars 2 900 was the same the reflector 144 x 5 was 96 - 98 f, exhaust air 60 X 5 was 96 f Mars 2 94-96 f depending on location reflector was 86 f.
As for the color are the lights the same NO there is more white in the 60 X 5 but there seems to be no difference in bud development or growth between any of the lights the only noticeable difference is the buds under the intensity of the 900 Watt lights want to keep growing so flower time has gotten extended but that has to do with plants that outgrew their home and kiss the light goodnight.

My tent is 6.5 X 6.5 ft and I run one 600 cfm exhaust and a 300 cfm exhaust with three 16 in circulation fans keep the temps mid 70 f lights off and mid 80's lights on, my area is a high temp (100 - 110 f ) one and in the summer it all runs.

This has been my experience with these lights not what I read or heard they are what they are a cheaper spare, or a light for fill in, or a way to start the hobby without spending a lot of cash or a light to start seeds while your main light grows plants

Dark, feel safe to use the Old Model,the casing will not melt after one year, they will of course last for more than a few months, I suppose the most common problem it will have may be leds, as long as you change them, it will be OK,

nice! tyvm for theses infos randy ... really appreciated.

yeah yeah, im not stupid, i know this is just ebay competition ... but i want to know if the light will last more than 1 year and how strong cause cooling is so much important in leds panels ..... with your infos, it seem very good and working as others panels. you are very kind.

just waiting on Sara to confirm if this light will last more than few months .... i think so, and hope so, cause im about to buy it

ty randy

hi, kpunx, the Old Model is not the same quality as MarsII and Reflector, if it's within the buget, I advise to choose MarsII and Reflector series, while the Old Model for the price is worth a try. The Old Model is manufactured in the same factory, the same workers and yes, with lower quality components than MarsII and Reflector series.

Hey Sara, I have read you personally saying that these 300w 60x5 panels are not high quality. Saying if you can afford more, then you should buy better lights. That these lights are only made to compete with the cheaper lights on eBay and amazon. If Greytail reads this thread, I also read that he was going to purchase another 100x3w panel, but when they were sold out, he opted against getting the 60x5w. However, I've read in a couple places where he was recommending them to other folks.

What spesifically is not as good about these lights? What brand and model LED's are they? What temp do the panels operate at? Are they manufactured in a different facility, by different people, or with lower quality components? They seem to be priced just about in line with the 100x3w ($75-100), so what is different that makes the inferior, and have less warranty?

 

[Mars Hydro]

yes, there is 100% chance for Europe friends to get Reflector 96x5w.

Hi Sara, any chance to see in short time in europe the Reflector 300w panel layout with the new 5w leds??

TIA

Mox76

 

[Mars Hydro]

thanks, RaoulDuke, I couldn't to wait to see the set-up.

Funny that this topic is coming up, I sent Sara a PM just yesterday withput reading this thread. I too just purchased a pair of the 300w models through their ebay store(alongside a 1600 from their website) and am curious about what to expect. Considering the price I really can't complain much, I'll be happy to get around a year out of them but hopefully longer.

I'm also content with replacing/upgrading components that might be faulty if there are parts available. Hopefully Sara can chime in.

 

[Mars Hydro]

my mouth is watering, they look so hot!

Bud-trichome shots
Around 3 more weeks before harvest

 

[Mars Hydro]

Haha, you are mature and have a young state of mind.

Hey Sara, are you calling me immature...?

 

[JC Dozer]

Thanks for the help/replies. So this a leaf I n daylight. I am on the 4th run of this, the last three under hps bulbs with no problems. Needed a bit of humbolt (can't remember product name - call mag iron) during end of explosive veg faze to green off new shoots but that is all. This last feed tank made up with 50/50 grow/flower nutes, 2ml litre cal-pro and oxy plus. Ec high at 2.8 but using very hard water n not had problem at this strength before with other lights. Used same amount of feed before but cal-pro is on top of that this time so could be nute burn I guess but never had it looking like this before. Many thanks for your input. Smile

So this is a bump and question for smokesara. I have backed off on nutes and will know tommorow if that is my problem. Question for Sara is I noticed that the led configuration is different between my 144x3 and my 144x5 giving a noticeable different in colour between both lights on all settings. Why is this? I'm not complaining as between the 2 I should have a bigger spectrum of light covered.. But maybe one is better than the other for veg stage??? Thanks, JC

 

[Mars Hydro]

Hi Kindr3d, MarsII 700w will cover about 100x100cm at the height of 60cm. It's a little more for vegging. MarsII 400w is the right one for 70cmx70cmx160cm tent during veg. Or you'd better hang it higher to avoid too much heat.

I have a Mars hydro II 700w light I just got in a 70cm x 70cm x 160cm Mars hydro grow tent.
My question is IS this light too strong to start vegging?
I'm in hydro ghe drip feed all parameters are perfect PH Ec and I'm getting rust spots on the 1st true leaves this is my second attempt I had to dump my 1st attempt.
Should I get with a different light and use the 700w for flowering.

700W is perfect for 80X80 ... so just little more or little less is ok.

you just need to keep the light little higher to be sure. for vegging, and if you think the light maybe little too strong ..... keep the plants 24 inchs under the light and you will be safe for any kind of light damages. 30 inchs max will be clearly enought if you want to be completly sure.

for flowering keep it at 18 inchs and you will be safe too. 15 inchs is better if all is ok.

 

[DarkSidofMike]

ok then ... where can i find thoses LEDS if one day i need it? you can sell them? if yes, how much on average?

tyvm Sara

[Mars Hydro]

nice buds! share us the result, it must be very good.

So heres my latest and greatest. This was a weird plant, I dont think I'll do it again. It's Dutch Passion Think Different Autoflower. It stayed really short, but has some huge big fat buds on it that would probably knock someone out if they were hit over the head with one. I'm not sure if this is how this plant grows or not. I saw some bigger ones on the internet of course. I'll take the results though. I had so much sticky stuff all over me I had to use a bottle of Goo Gone to get it all off

Dutch Passion Think Different Autoflower grown under Mars II 400 watt.

I love my Mars II lights, so happy I made the investment, worth every penny

Here Sara!

 

[Mars Hydro]

tonydavis, you can have a try, you'll make it.

hi there! it looks very nice! did you grow that single plant under the light?
(I tried some dutch passion autos a couple of years ago, when all this auto stuff started, but those plants stayed some 15-20cm tall... as I see, things have changed with auto plants. maybe I'll try it again.)

Ha, yes, before we have MarsII 700w on sale, the price is quite tempting.

Usually autos is about all that I'll grow. They are just much easier for me, and I only grow for my personal use, so I have a lot stored up in my secret hiding places

Yes, I always grow one plant under one light. I have 2 - 400 watters going at once in different rooms. I wanted to get one of those 700 watters when they had them on sale but I missed the sale.

 

[Mars Hydro]

hi, maccamoo.

Nobodyuknow.......

Nice plant there. Hope it smokes well for you.
How long did she take from sprouting until harvest?
Thanks

when the plants tell you to wait a little longer, you will get more.

I usually let mine go to 11 or 12 weeks total from seed to harvest. You can tell by the leaves I let it grow a long time. I like to get that narcotic effect from my plants. Seed companies will tell you 60/70 days on seeds, but I never go by that. You can, but usually you will notice that your plants can go much longer.

This particular plant went 12 weeks. I harvested her last night 7/25 exactly on her 12 week birthday.

This was one of my last plants I grew and I let her go to 11 weeks and then I just couldnt take it anymore!

do you flower with 18 hour of light or just 12?

Haha, thanks for the generous offer.

I just do 18 in the summer, off time is from 12 noon until 6pm, the hottest part of the day. In the winter I go a full 20 hours until harvest because the lights help heat up the rooms. For me, just flowering an autoflower for 12 hours is a waste. The clock is still ticking and you dont have the time to waste like you do an on a photoperiod plant.

Heres my secret stash, all 100% Mars Hydro grown with the Mars II 400 watt lights. I've given away about this much, and this is whats left for myself and Sara

The bottom jars are 2 quart jars, and the smaller ones are just a quart.

nice collection buddy!

and u grow in a very smart way with these light hours!

how much dry grs do you pull from a plant in average? your last plant on that video?

you have a scale in your heart.

Ya know, I keep saying some day I'll buy some scales, but everytime I have extra money to invest in this project I end up needing something else, and then I get to the end and I think oops, no scales. So I really have no clue
