Mars-Hydro LED Grow Light Discussion

[Dennise]

The answer IMO is yes... I started with 1 96x3w and now have received over 10 lights from Sara.... I actually really have lost count but no doubt when I started adding more light my produce was more resinous and IMO helps increase my yields.....

Hello hunterwithpet, all our lights, no matter on EB or our website, has the same specification. Except for our old model and sun series, all our lights still have IR light in the,

"By the way, we stoped adding IR lights on our old model series since April 2014"

Is this because of the price or? And whay specification on EB,.. basically everywhere - still say IR in Spectrum?

Hello solomum, can you tell me what is your RH? Is it above 50%?

Hello, Ive bought a mars II 1200 led panel. My tent is only 80cm x 80 cm x 160cm. I was not aware that the mars would be that heavy and big.

I started growing a plant in my garden then only after two months moved to the tent for the flowering stage. THis plant is tall already and I only managed to put it 35 cm away from the led panel. THe tent temperature is at 32 celsius maximum. After two nights of 12 hrs with led on, the upper leaves are going dry, burning at the top and the plant overall look is not that healthy. What could I do? ty

Thanks hunterwithpet, in fact, with the hight solomum hang the light, the light can still be used, I was wondering if it is the RH problem.

Cooking and growing isn't the same thing.

I found this on a local forum:

Wide/deep
150W - 0,6m x 0,4m
250W - 0,8m x 0,6m
400W - 1,2m x 0,8m
600W - 1,5m x 1m
1000W -2,5 m2

Can you share us a photo so that we can help you find the problem?

Was this an answer to my questions? Sry I didnt get it. Wide/deep?


Cooking and growing isn't the same thing. Ty for the advice. What do u wanna say with that? Too hot of a temperature? How away from the mars II should the plant be? And whats the maximung temperature I should be going for? I currently have a fan scuking air from the carbon filter to outside the tent, but dont have a cooler pullng air in.

Had I started growing it in my tent from the beggining, do u think the plant would grow taller that it should? It would reach a pick before growing too large to the point it would get too much heat?

Ty again.

Hello solomun, the strong light might be the problem, you can consider replacing a smaller lights, such as our 700w light.

The heat might also cause the problem.

hey I'm just a noob, but still: the optimum temperature for growing weed is between 20ºC and 25ºC, someone will say 30ºC because you use leds, but the plant already show you how that won't work in your small specialized grow tent. Too much light from all directions, and oblivious, too freaking close for an 1200w (600 real) 5w led light.

Move your plant back to old place and go for old school hps mergers, what means: 40-55cm for 600W away from the top of plant or prepare yourself for worst scenario. I think.


But actually i never grow nofing, so wait for more expirience people.

Thanks spiritmoon,

Maybe heat issue, because i have 100cm x 100cm tent with Mars 2 1200 above 30cm from canopy and the girls like it a lot without problems

Ps: can someone tell me the maximum watts/sqf can i put above my girls with Mars 2? I have 100cmx100cm tent with 1200 mars(approximately 51w/sqf right?) how much more watts/sqf can i put on it?
TIA

 

[Mars Hydro]

Sure.

Well...you know where I live and I have extra cabins.......so when your ready for that vacation visa' s here are EZ

Hello kungsan, thanks for the sharing. Plants look good.

Bought 2 mars 1200w. i have them on lightrails. the girls are in a aeroponic system about 5 weeks old. adding 3 pic below. very low temps in the grow room 24-25 celsius.

last pic is close to harvest hps 1000w and 600w

 

[Mars Hydro]

Good morning KJC

You want from 70°-90° Fahrenheit or 20°-30° Celsius and 50%-70% humidity for vegetative growth and 30%-50% humidity for flower.

Hello BetterThisWay, thanks for trusting us.

From everything i see it seems that this is exactly the case. I wanted to buy a led for quite some time, and it seems i'll finally have the money for it in about 2 months. Thank god for their more than competitive prices! Bless you Sara!

The first preorderered Sun series will ship out just these days. But we will not have stock in our warehosue in around half year.

Btw miss Sara, can you please tell us when can we expect the Sun Series to arrive, approximately?

Hello Cthulhu, welcome to the growing family. , for the tent space, you can go with 2 mars II 700w light, it can give you amazing result. The teperature of our lights usually will be around 20 degrees, so please do not worry the heat.

Hello everyone!

I'm getting ready to order all the equipment for my first ever grow! WooT! I am buying a 4'x2' tent and 300w old model mars hydro's. I was told that while 2 300w mars lights would work, adding a 3rd in the mix would be a huge(25-33%) yield increase. Is that a realistic increase for getting one extra light?

Also how hot would 2 or 3 old model 300w mars lights get in a 4x2' space, would a 190 CFM with filter be okay to cool that area

Good point brolyuto

Hey Cthulhu,

Congrats on starting your first grow! Very exciting time indeed. IMO I would go with something from the Mars II series. The 900W ( 425W draw, $350 ) is an excellent choice. Plenty of success stories with that light. I might even go with one of the new sun series LED's over the mars II if you can afford the $450 price tag. Either of these lights will dominate in that 2 x 4 space you have...and even give you some upgrade room if you decide later you want a bigger tent.

About your questions. I think it's a good idea to use multiple lights...you can angle them and get more spread. Though no matter how many lights you have it's all about how many watts you have. So 600W in 1 light or split into 3 lights should give you the same temperature. If you can maximize air flow then either setup shouldn't give you trouble. You can take this one step further and throw in a C02 bag, it well allow the plants to tolerate higher temps and do wonders for your yield .

Email me when you are ready to order, we can help you with the payment way.

My budget is pretty wonky, basically I have 2 $300 credit cards with 0% interest, so i cant actually purchase anything over $300 despite having double that in a budget, the 3 old models are, from what I've found, my best way to get 450 watt draw in LED's in a 4x2 area, I may be wrong. I really dont even have more than $309 I have budgeted out for the lights, and i have to buy those on two seperate purchases. If you have any other ideas on lights im more than open to hear them

Also would the additional 300w light actually produce a 25-33% yield increase from the extra light or anything even close to that figure?

Also I dont know what the heat produced by any wattage of LED, thats why i asked if that size of fan would work.

CO2 is probably way out of my price range and i need the smell to go through a filter so i cant make my tent airtight and just artificially introduce CO2 anyways

 

[Mars Hydro]

Ahh I see, well that is one interesting budget. lol. But hey you do what ya have to. I think as far as performance per $ you'll be hard pressed to find a better deal than the Mars hydro LED's. For what it's worth, the Mars II 700W( 340W draw) is only 289.00. I would go with 2 of those.

I mean added wattage will give you a greater yield.. 2 lights better than 1 and 3 better than 2. I haven't read anywhere about anyone using 2 and then specifically getting a 25-33% increase but you CAN be sure the more light you have the better the yield.

That fan will work fine for what you have. Just try to crack the tent open to allow better airflow. More air= better. More light=better.

Also i'm not sure where you are but check your local hydro shops...most have some kind of c02 producing fungi bags for cheap. It's $30 where I am. Lastly C02 is hevaier than O2 so it will just fall to the tent floor.

Hello Cthuhu, may be you can go with one light first. a 96x3w can cover the space well and the price is affordable, When you have money in future, you can add more light.

Lol buying 2 700's would be awesome, unfortunately, i couldnt even buy seeds, let alone a tent, soil, nutes, a fan a filter, etc if i did that. Also just one would leave a whole foot of tent out of the light.

I'm not saying a specific yield boost, Im saying is that somewhere even close to realistic, is it at all realistic to think a plant that would of given 28g could now give 35g? I cant find much on peoples yield after adding an extra light so I was hoping someone actually has just added a second light with the same strain and seen a decent increase in yield, nothing specific but a decent enough increase for me to pay off the extra $100 in one grow.

I was going to open bottom flaps for passive intake as long as it will maintain a negative pressure.

I'll check for those actually, I've heard a lot on adding CO2 but I also heard its not really doing much unless you have your tent air tight so all the CO2 doesnt get pulled out the fan.

Good morning Dennise.

I'd like to shoot for at least a 40+ watt draw per sqft, currently I have $309 budgeted out for lights which is perfectly fine as thats just one months savings after harvest, however i really cant go over $309

 

[sknygenez2]

Quick pic update on my Mars 1200w scrog day 25 of 12/12. Took a couple of shots with the light off and an upskirt

She's about to REALLY start packing it on. I took this pheno 12 weeks last run and she gets fat ass buds.

 

[Mars Hydro]

I understand your situation, how about use one 192x3w light, it will have actual draw power of 350~400watt, will provide enough watt/sft for your space. Besides, the price is below your budget.

Hello Cthulhu,

I'm still too new to send messages to anyone but staff. However I should be getting my first credit card tomorrow, most of that will go to a tent and seeds and fan but i should have enough for one light as well.

So should I not go with 3 300w old model's and go with something smaller like the 96x3 reflector, i dont feel like i would get the same yield going from 450 watts to 170 and i'd still be paying 55% of the cost of all three old models for one reflector. I know they are your bottom of the line lights but it seems like everyone is pushing me away from them on this thread lol.

 

[Mars Hydro]

Hello everyone, this week is our last working week before our Chinese New year holiday, so if you have any questions on the lights or any needs to order our lights, please contact us ASAP. Otherwise we may not solve your problem in time, or the shipment might be delayed.
By the way, our container has arrived our UK warehouse, and we will have other container arrive our US warehouse in a few days. Please feel free to order from our website during our holiday. We will still arrange shipment for you at home then.

I can dig that, i'd have to wait an extra week to buy it for the 2nd credit card to arrive and all I can actually spend on one card is $300 so I'd have to do 2 purchases or something. Are the reflectors that much better than the old models?

Hello Cthulhu, you can go with old model for sure, three of them is still within your budget. They can bring you good result.

Sure, you can order the light the next week, but we will not work then, so if you want to order, please email me or order from our website directly. Reflector series can reflect 100% lumen output, better coverage. Also, you can save a lot energy by using the veg bloom switches. But it is your choice to choose which light to go with.
