nice buds!!!

Just harvested off my mars2 1200 this evening. Just a little auto grow that spent the first 4 weeks under a 400 watt hps and second 4 weeks under the mars once I'd bought it

Congratulations Maccamoo!

 

[Mars Hydro]

well done

if your choice is 80X80 you should go for old model 600W(or 2X 300W) minimum ... mars2 700W is better
if your choice is 100X100 you should go for mars2 900W minimum ... and mars2 1200W is better.

the perfect fit for the mars2 700/900/1200W for FULL LIGHT POWER and high yield flowering are .....

mars2 400W = 60cmX60cm or 2' X 2' (4 square feet)
mars2 700W = 80cmX80cm or 2,6' X 2,6' (7 square feet)
mars2 900W = 90cmX90cm or 3' X 3' (9 square feet)
mars2 1200W = 105cmX105cm or 3,5' X 3,5' (12 square feet)
mars2 1600W = 120cm X 120cm or 4' X 4' (16 square feet)

depend of your choice, 80X80 (7 square feet) and 100X100 (11 square feet) are very different and are not the same area at all

if you want to go for real cheap and save money .... go for 2X 600W "new" old model panels (120X5) instead of mars2 900/1200 and it will be very good. (600W "new" old model cover about 85cmX55cm or 5 square feet each) ... 2 panels 600W would be cheaper than mars2 900/1200 but maybe better too, cause more smaller panels mean better light distribution over the area. Old model panels are only sold at amazon or ebay.

happy growing

Morning Sara....

 

[Mars Hydro]

Morning, supergroomer, You're like my old friend.

Morning Sara (or evening ) Congrats on the 1000+ pages. I think I have been here for a little less then 1/2 of those. I think there were about 500 pages or so when I started. Here are some pics of my latest harvest. I took my Blue Blood most of the way down. I left the bottom 1/4-1/3 to fill out a little more.

Hi, LEDCanuck, thanks for choosing Mars-Hydro as your first jump, it's truly a grea honor 2pcs Reflector 144x5w and 1pcs Reflector 96x5w is able to cover the grow area, while, to replace 2X600w Hps, 2pc MarsII 1200w is better.

Hello everyone (and Sara!), thanks for this great thread. I'm an ex-HPS grower of 7 years that is finally looking to make the jump to LED's. My intensive research has me looking at the lights offered by Mars Hydro, and the posts in this thread have given me the confidence needed to take the leap of faith.

I think I've settled on using a few of the Reflector series of lights in my room, but would like some input on actual LED wattage per square foot. I have a grow room that is 4ft x 12 ft, and plan on going with a 3ft x 8ft SCROG for 24 sqft of growing area. Previously, I have used 2 x 600W HPS to cover roughly the same area. The coverages of the Reflector LED lights are listed, but I believe that they are a little exaggerated and want to make sure that I have enough light. My plan is to order 2 x Reflector 144's and 1 x Reflector 96. The 2 x 144's will be set up parallel lengthwise, pretty much touching, to cover a roughly 3 ft x 5.5 ft area. The Reflector 96 will be turned sideways and added onto the end of the other two lights to cover the remaining 2 ft x 3 ft swath. This gives a total of 670 - 800 actual watts (based on manufacturer's specs) for 24 sqft of canopy space = 27-33 actual watts per square foot. I've been reading that 25 actual LED watts/sqft is sufficient, is this the correct amount of lighting for my planned SCROG? Are the 3 Reflector lights I am planning on buying my best option? I am trying to minimize fans and noise in my set-up, and would like the coolest running lights possible, which is why I am looking at these lights over the Mars II, but any and all suggestions welcome. Thanks!

thank you

it is better to aim 45-50 watt/sqft to have result comparable to HPS.

the best replacement for a 600W HPS are the mars2 1200W or the NEW reflector 192X5 maybe not bad .... old reflector 192X3 is little short of power.

old reflector(192x3) consume around 360W and the new reflector (192X5) around 420W true watt. 2 panels of mars2 900W maybe not bad too, but not full power as 600W HPS. go for the all new reflector 192 with 5W chips ..... 2 panels 144X5 + 1 panel 96X5 maybe good yes. but with 5W chips, not 3W.

happy growing.

LEDCanuck2 Welcome!

Colorado Finest runs a lot of different Mars Hydro lights and he is a great source of information. Check out his Grow Journals on this site as well as his videos on youtube. I know of one video in particular where he is running 3 144's. I haven't seen the "real" specs on the 144x5 as it seems the info is still the info for the 144x3s on the sight. The coverage on the lights are slightly exaggerated as the 1600 is more like 4.5x4.5 than 5x5. I too plan on buying the reflectors assuming they are more like 5.5 x 2 coverage area. It was confirmed the draw from wall is also slightly lower than advertised. Don't let that deter you as people swear by these lights and have shown good evidence of their capability.

 

[Mars Hydro]

Thank You! Hmm... although it's different from data at the website, I have to day, it's of more reference significance.

coverage and perfect fit for mars2 and reflector series (Full light power flowering)

OLD reflector 144W(48X3) = 40cmX40cm each
OLD reflector 288W(96X3) = 40cmX80cm
OLD reflector 432W(144X3) = 40cmX120cm
OLD reflector 576W(192X3) = 80cmX80cm

NEW Reflector 240W(48X5) = 45cmX45cm each
NEW Reflector 480W(96X5) = 45cmX90cm
NEW Reflector 720W(144X5) = 45cmX135cm
NEW Reflector 960W(192X5) = 90cmX90cm

mars2 400W = 60cmX60cm or 2' X 2' (4 square feet)
mars2 700W = 80cmX80cm or 2,6' X 2,6' (7 square feet)
mars2 900W = 90cmX90cm or 3' X 3' (9 square feet)
mars2 1200W = 105cmX105cm or 3,5' X 3,5' (12 square feet)
mars2 1600W = 120cm X 120cm or 4' X 4' (16 square feet)


this is for full light power flowering like HPS ... less than that can be good, but is not full power.

 

[Mars Hydro]

Yes, you can daisy chain 1pcs Reflector 96x3w with 1pcs MarsII 400w. No problem with that.

Cheers Sara, so just to be clear so i dont blow any of my lights ill be pluginging a 96 x 3 Refl. into a 400w MarsII and then to power socket. This is all good to do if anyone can confirm that with me

she confirmed with that answer lol

"You can plug Reflection with MarsII, just make sure the total power will not exceed 1000w."

your total power will be 370 watts (190+180) ... so you are ok

It's the draw power you should add.

I know yea im just a little slow lol
Thats sweet then i wasnt sure if i was adding up the draw power like u did, or the output power witch would of been 700w
cheers

good question ..... the total power to considere is true watts .... watts from the wall.

Hello everyone,

I just started my grow less than a week ago. I am using (2) of the Old Version of the Mars-Hydro 300w lamps(White). I am growing White Widow and Bubblegum in Coco Coir with 3 Gal. fabric pots(and a solo cup for the bubblegum). I am using a 32x32x63 grow tent. Right now I am running both lights, and have them just under 18". What would be a good height for veg and is 2 of these LEDs @ 300 watt too much?

 

[Mars Hydro]

Right, Reflector is updating to 5w led chip.

New reflectors with 5w chip? is this right

haha, also in the middle of taking the advantage. The price has not increased yet.

yes, reflector series is upgrading to 5W ..... you have to be sure you buy the right one theses days, cause we are in the middle of the change.

 

[Mars Hydro]

best than most. The right spectrum is the key.

Welcome Canuck

Its hard to compare HPS to LED watt for watt. LED grow lights are designed to produce only the wavelengths used by plants therefore there is no wasted light.

Earlier today I came across a youtube video that compared the results of a 600 watt LED (draw watts) vs a 1000w HPS. The 2 produced more or less the same weight, within a few grams of one another, but the LED drew 400 less watts. (not to mention the heat difference)

But even more interesting was that they had the bud lab tested and the LED out preformed the HPS in both potency and terpenoid levels.

Something to consider more than just raw power

 

[Mars Hydro]

OLD reflectors with 3W chips consume 90W true watts for each 48X3 led panel ..... NEW reflectors with 5W chips consume 105W true watts for each 48X5 led panel.

new reflector 192X5 consume 105W X 4 ... so 420W ... nothing more or less

true watts = watts from the wall = actual power = power draw

 

[Mars Hydro]

Yes, Reflector 5W is for sale now. US and EU friends will get Reflector series with 5W leds.

Got Cha new reflector lights NICE I dont know to wait and get one of them or get my MarsII are they out now for sale the new 5w's ?

you better ask them via email ... this is different for each country ... depends of the stock at their warehouse for your region.

cool sound man

 

[Mars Hydro]

Mars hydro LEDs panels are not comparable to High quality LED panel like kindled or hydrogrow ...... best LED panels like kindled use around 30-35w / sqft to compare to HPS ...... mars hydro LED panels use around 45-55w /sqft to compare to HPS. (HPS use 60-65W / sqft)

so, to replace a 1000W HPS (4'X4'), high quality panels (kindled) use around 500-600W true watts .... and medium quality (mars hydro) use around 750-900W true watts

but mars hydro panels cost 1/4 of the price!!!

they also produce just little more heat than high qualitys leds panels. only little more. .... nothing to compare to HPS

 

[Mars Hydro]

Congrats on the Harvest! Yummy Yummy... curious about the weight.

Just harvested off my mars2 1200 this evening. Just a little auto grow that spent the first 4 weeks under a 400 watt hps and second 4 weeks under the mars once I'd bought it

nice buds!!!

Congratulations Maccamoo!

Welcome Doobzilla, you'd better to hang it higher above 24", the small babies may not be able to handle the heat.

Thanks for the reply Sara and thanks a lot for the help everyone, this is a fantastic thread. I am so excited to get started with this LEDs So Sara, the new Reflector 5W would not be available to me here in Canada?

 

[DarkSidofMike]

hello Doobzilla

no, 2X "new" old model 300W panels are not too much for that area. you have 7 square feet total and each of your 300W panel can cover 40cmX55cm (1.33'X1.8') or 2.5 square feet each. so in fact you are little short for full light power, but it is not bad for sure, and you will get good result for it. even if not full light power.

1 panel mars2 700W is better if you want full light power ... but 2X "new" old model panels is clearly not bad

[LEDCanuck2]

DarksidofMike, thanks for your help in this thread. It doesn't sound like the Reflector 5W panels are available in Canada, so I may re-jig my original plan and go with the Mars II lights. Based on what you and others have posted, it sounds like 2x MarsII 900W will work really well for a 3' x 6' area......I think I will shorten the length of my planned SCROG and go with that. Based on some of the pics and yields posted in this thread, I should be able to get a decent pull from two of those lights at a total of 800W actual (min) for 18 sqft = 44.4 W/sqft.

I see the options for the MarsII lights are different on the Mars Hydro site vs. topled........with the Mars Hydro site, they are full spectrum and are good to go for both veg and flower, correct?

My other question is about heat.......how much heat do these Mars II 900W put out? My 3 ft x 6 ft grow area sits in a larger 4 ft x 12 ft room with 8 foot ceilings, wondering how much they will raise my room's temp.

 

[DarkSidofMike]

yep, all their light are full spectrum and are doing good for vegging and very good for flowering.

the heat will be very low compare to HPS or any other light source, only little ventilation will be needed .... 400 cfm blower will be clearly enought , maybe 200 cfm will be enought. not sure exactly what you need for vent, my speciality is light and area lol

2X mars2 900W will rock for your area, no doubt.

happy growing.
