Mars-Hydro LED Grow Light Discussion

[Mars Hydro]

wow, 3 harvest within 22 weeks, that's really awesome.

wow, vegging for 10 weeks! ScrOG are definitivly not for me with a so long vegging time. 10 weeks for vegging + 8 weeks for flowering! 18 weeks is so long! i can make 3 harvests in little more than 22 weeks!

the buds are amazing no doubt .... very big and nice looking! it make good pictures for sure

but at the end ....... 3 harvest in 22 weeks is amazingly more productive than only 1 in 18 weeks

you should think about SOG Denise. (many many plants with very short vegging) ... you will get more than 2 times your nunmber of grams after the same time with the same area.

 

[Mars Hydro]

hello CO Finest~~ so happy to see you here~~

With 9.4 sqf 347 wall watts from led will be enough for flower for sure.

 

[Mars Hydro]

haha, Mike, thanks for the info

really didnt want to putting down Denise great work .... this is only and advice for more grams at the end.

for sure you need to clone for that.


and even if you have a so nice reputation ..... 347w power draw is not enought for 9.4 sqft if he want full power. this is 36w / sqft and this is not enought.

please stop giving advices for medium light power .... 95% of the growers want full light power.


by the way .... 3.2 X 3.2 is not 9.4 sqft ... it is 10.24 sqft

a mars2 700W panel consume 315W .... so it will be 30W / sqft .... this is not enought
a mars2 900W panel consume 405W .... so it will be 40W / sqft ... this is good but not full power
a mars 1200W panel consume 525W ... so it will be 50W / sqft ... this is perfect for full power


for me, the best setting will be even more .... 4X mars2 400W will be amazing for that area ..... if you add CO2 and grow hydro, this is not overkill at all

 

[Mars Hydro]

lol, the first point makes sense.

So... if most of your 95% HPS growers us 1k watt for 25sqf aka 5x5 and LED uses use 37watts x 25 = 925wall watts you say thats medium power that 95% grower do not want which is the same 37 wall watts used in the 9.4 sqf space. Ok brother take over helping everyone good luck with that and that was 37 not 36 but if you need the true number its 347.8watts peace...If you can private message me all your grow links I would love to check them all out.

 

[Mars Hydro]

thank you, Mike for these advices. There are no abosulute right answers. People here are all experienced growers. There are a thousand Hamlets in a thousand people's eyes. I believe everyone has his own experience. Thanks to 420 forum, we have a place to share with each other.

1000W HPS for 5X5 area is not enought and is not using the area at full pace. 1000W HPS is for 4X4 and everybody know it.

yes many growers dont have high rating settings and can do really good with 1000W HPS for 5X5 .... but if you have a high rating setting you need more ..... every experience grower know that.

i repeat .... even if you are famous, you are giving bad advices .... most of new growers want full power and you are not giving good advices for them


yeah yeah, i dont have a journal for now ....... im not here for that anyway .... im here cause i noticed there was bad advices in there, and i want new growers to start with full power, not medium. even if maybe they will not need it.

this is the only reason im here .... giving good advices cause mars hydro leds panels are not doing magic like some of you are thinking.


CMDRbaked was using a 600W HPS for 1 square meter (10.8 sqft) .... so he want full power cause this setting is full power

 

[Mars Hydro]

well done! Dennise~

Hands down the best grow I have had and the most dank buds for sure... On a scale of 1-10... I would give the Mataro Blue a 8.5 and the Jack Herer about an 8... I think after they both have a good cure... they will be off the charts... I got a final weight on the JH this morning and between the 2 girls I harvested right at 8.5 zips.......

well said, Celt, plants mostly use light from a different part of the light spectrum than what human eyes are most sensitive to, grow lights – such as HPS or metal halide – that don't address plants' specific spectral needs are not tuned to effectively facilitate optimal growth (Source: Internet). This is the difference between HPS and LED.

Mike mate, I believe you need to do some more research to have a better understanding of the way plants use light.

Lumins, wall watts etc have little to do with how plants absorb light. You say people like CO Finest are giving bad advice but you are comparing apples to oranges comparing watts HPS to watts LED.

Because HPS produces a lot of waste heat and light outside of the needs of plants, that means wasted wattage. LEDs on the other hand, when designed for plant growth, produce only the spectrums needed by plants with less waste heat. As such, LEDs require less wattage per sqft to replace HPS.

Before you call out someone for giving "bad advice", especially someone who has much experience in both HPS and LED lights, do your research so you know the facts and can compare accordingly.

And as CO said, keep it growing green

 

[Shaggn]

Hi Sara, just wondering if you have any mars ii 1600s in Canada, Thank you!!

 

[Mars Hydro]

yes, but I have seen people use 600w HPS to cover bigger area.

he was using a 600W HPS for his area .... and to replace a 600W HPS you need a mars2 1200W .... i have nothing more to say

 

[arellanobrian]

Tomorrow I am ordering 3 Mars Hydro 144x5's that are going to be hanging in my 5x5 for my current grow. I guess I will find out if @ 38w/sqft is enough. Personally I am optimistic because I am going to get good light coverage and I am confident in the product and recommendations. I will further withhold my opinion until I can provide results of my own.

i think youll be fine man, im getting good results with my 144x5 so with a little TLC im sure youll get some awesome results

 

[Mars Hydro]

hi Camelion, thanks for coming here. 2pcsReflector96 will cover4.4'x4.4' @24" while MarsII900w will cover 4'x4'@24". Haha, 2pcs Reflector will give your more flexibility and Reflector has switches for veg and bloom.

Also "new" here, reading a couple of weeks already but finally the registration and the first question.
Wich one would be the best option in a 1m x 1m x 2m tent.
2x 98x5w reflector or 1x 900w Mars II?
I"am leaning towards the 2 x reflector because they are also 5w now...

 

[Mars Hydro]

thank you for the help, Mike.

minimum mars2 900W .... mars2 1200W is better

yes 2X 98X5W relfector will be good too and better than 900W ... but mars2 1200W will be better

 

[Mars Hydro]

Haha, Gnarl, how are you? Why I am so much happy...

They say you can't argue with success, but some people still try.

 

[rhetorrikz]

Hi sara ,can i trouble you for some info on the sun series lights .
What sizes are available ? Light footprint at what height? Atcual wattage draw? Less heat than mars 2? Please pm some prices thankyou!

 

[Mars Hydro]

thank you, Griz, it explains well.

TBH I have never understood the watts per square foot argument @DarksideofMike.

Not mentioning names of other products but as an example I know of one grow light that does 130000 LUX @ 440 Wall Watts for a 4x4 at 24"
The Mars 2 1600 draws @ 780 Wall Watts with @ 19000 LUX at < 31" with a 4.5 x 4.5 coverage

With the watts per sq foot theory, the Mars 2 would be the better light but the other lamp puts out way more light with a better spectrum (at 4 times the price). That light would be @27.5w/sq ft, a low power light by the standards you explain. LEDs use about 55-65% of their rated power so they last longer. If LED companies went with the watt theory wouldn't they just boost the LEDs to use more wall watts?

I'm choosing Mars Hydro for the customer service, great price, and the great recommendations backed with proof of results. Mars does the job and I think the results say more than the watts. Mars is providing a product at a far lower price which is great for a majority of those growers that want to get into LED growing at an affordable price.

 

[Mars Hydro]

WOW, Randy you always have a way to take the discussion to another higher level. I love here, I love all the friends here.

If you look at the original chart it was intended as a comparison of the different types of light used not as a absolute answer for how much light you need just a level playing field for all lights and each has their own range of wall watts. Then there are so many different aspects to take into consideration one main point is how much of the area is to be used just because you have thirty square feet if your only going to grow one plant do you need 1500 watts?
There are many successful growers here who with their styles have shown grows that even with mid thirty wpsf are readily done and they prove it with pictures and results showing they use the equipment that is recommended. Many of these growers have been here since the beginning and have well into the twenty Mars Hydro light range and have used other manufactures products but still come back so there must be something good going on here.
Then we get the people who show up tell everyone what they need and how to do it. That the lights are not right and they can grow a huge amount in a short time from seed and everyone needs the largest lights and max output but oddly we know that some of the cheaper smaller lights have been purchased but have yet to see a grow picture of even a sprout.
Personally telling someone just starting to go the max route is a quick way to failure there is a lot more to this than add light pick bud and it needs to be understood and developed at a sane rate I also believe many small lights are better than one large, I mean do I start seeds with a 1600 watt panel or use it to veg two plants?
I don't think so, myself aprox 25 wpsf sprout or clone, 30 - 35 wpsf veg to mid flower, 45 + wpsf mid flower to harvest (last 4 wks) this works best for me and gives a balance between power used, heat and output. During my last grow to establish a Mother plant for future grows from 4 strains the winner averaged 600 grams per plant and buds were near the same size, density,and resin development whether under a 900 watt Mars 2 or a 96 x 3 reflector and when the much criticized 60 x 5 was added they stretched to get under it and got larger.
The only real benefit I see with higher light output is finishing the plant it seems that with moderate light intensity some plants will just go on and on never really finishing which for a lot of people is not a bad thing resin color and effect takes awhile to understand

 

[Mars Hydro]

Thanks for the eye candy...

so frosty

 

[ganjazz]

Could it be that led grow takes abit longer than the flowering period (as discribed seeds) compare to HPS?

Looks like slower growth but only in late bloom to me, or defol maybe reason, not sure.

The buds though getting alot more dense last weeks.

All my girls are later in harvest, around 1-2 weeks i assume.

 

[Mars Hydro]

great!

I don't know where everyone gets there information, but I grow with 2 90W LEDS in a 2X4 tent. My plants grow fine and the light is currently six inches away. Sure I could get more grams from higher wattage, but when you pull seven quart jars from a single plant, I am satisfied. Maybe you guys should experiment, no telling what you may find.

 

[Mars Hydro]

I agree with you, santb. Mike is very warm-hearted and frank. and thank for the sharing!

I think DSOMike is trying to help but his english makes it sound (read) like he's being overly critical sometimes... DSOMike, you sound very enthusiastic and passionate to me! Going to the max you can afford given space/$$ makes sense; if you can nail down the environment/genetics then all mistakes would have to be the growers fault..
That being said; for myself, with zero indoor experience, with the literally 100's of hours of reading and questions about LED, soil, etc., I personally think it will come down to space usage.. Trying to put too many plants under ANY given light (the sun not included) will give lower-than-wanted results.. Even with environment dialed in...
Get the biggest/best light you can afford, and go from there... I got a 144x3 mars cos that was the easiest, best quality for me for the moment, but I'm not gonna try and cram 10 plants under it. Max 2 plants directly under it, and cross my fingers for 2-3OZ each; that's the plan (hope!) at least... I only want to veg for a short time also, but will go up to 8 weeks or more if necessary so we'll see what happens and adjust if needed...
K.I.S.S!
