Mars-Hydro LED Grow Light Discussion

Sara has uk Stock... :D

you tent is to small for the size of light... might not be enough height.... 2 x 700 would be good ..

One of my tents is 2.3m (7.6ft) so maybe i should use the 1200 in there? and the 900 in the 6ft6 - 6'6" tent?

Is this so much of a problem that i have to adjust the order do you think? Or can i work around?:s

Thanks for your input, much appreciated

Hey Dennise! Thanks for the hand :)

Both Veg and Flowering Tents are 4' x 4' x 7' (The Veg tent i got a little taller because there won't be a scrog screen in there and i'll have Autos)

Sorry life got hold of me for a bit... I think you will do beautifully with what you have ordered. My spaces are not as tall or as big actually and I am now using the 3w reflectors and and I love them. I won a Top Led tent that I am waiting for a Mars II 400 for so I can't really speak to them exactly but can only imagine that if the 3w does as well as it is doing that the 5w is going to rock but I looked up the coverage area for the Mars II in question and I think you will be fine and I am sure you will love them..... You are more than welcome to take a look at my journal and see what the 3w is capable of doing then you can dream of how much better the 5w will do...lol... Sara will be on here this evening I am sure and will take a look to make sure I am giving you the right advice on which power to buy but I am pretty sure she will agree that you have made a great choice.....:thumb:

You are a star, thank you so much for your help! I'm subbed to your journal now, those are some beautiful plants and some awesome flowers coming out of them! :thumb:

Lets hope our Mars lights serve us as well as your Reflectors have served you :) They can't get here quick enough, I feel like a kid at christmas, i'm absolutely buzzing (that could also be the weed though :))

Hi Wingnut420... I have 3 of the 3w reflectors and I absolutely love them. You are more than welcome to check out my journal and see what they can do but I am waiting on the Mars II 400 for my tent. It is a small tent and will most likely only finish 2 maybe 3 plants in it but I most likely will keep it down to 2 but either way it will be a bit before I can tell ya for sure which I like best but I can certainly tell you now that the 3w is making some really pretty buds on my closet girls!!!!....:high-five:

You have some awesome threads and posts!

Glad I moved over here.

Hey!

Did anyone win the first grandchild naming contest?

Seriously, my focus when studying these lights is light footprint in relation to a 1000 watt HID. As I posted earlier, I have friends with wharehouse sized legal grows. And they use 1000 watt HID and they budget a 4X4 footprint for each light. And they get a couple of lbs per lamp, give or take a few for genetics and hiccups. But they are pretty spot on years at a time.

So, even though we can buy a 1200 watt LED, and it might have the POTENTIAL to light up a bigger space, the reality is that we should budget ourselves for the lamp that will lite up a 4x4 space. So, in my mind, if 700 watts of LED equals 1000 watts of HID and actually can make 2lbs of weed (give or take) in a 4x4 area, and I have a 5x5 area or larger, I am going to get a second lamp so that the ENTIRE footprint gets light.

In my case, I have an odd sized room. Well, it is a cedar sauna no longer available for sitting in...because I have decided it is my grow room. Awesome space. Glass door...holes for ventilation, and CEDAR..bugs hate cedar.

So, it is 5 x 3.5. Odd shape. a 1000 would work, but I don't think the entire footprint will be equally lit. So, in my thinking, and PLEASE correct me if I am wrong because I have yet to use LED's, I am planning on buying THREE 400 watt Mars II, mount them on the long axis, link the two outside lites and the center one separately. Then I can veg using either 800 watts and if they are babies, just run the center 400 for starters and repots going into veg.

More lamps rather than one big lite so that the entire space gets equal lite. I can lower them if I need the intensity but I think 1200 watts distributed over three lamps is better than one 1200 watt.

Does this make sense?

Makes total sense. good plan.

Certainly does to me and sounds like a great plan! B-)

My grow tent is the same size...its the 2x4 hydrohut which actually measures 2.5x5'x7'. I have 3x Mars II 80x5w in their and it definitely covers the whole grow area nicely and is very bright. Seems equal to if not brighter than when I had a 400w cmh and 600w hps running :) but much much cooler and much less electric... sounds like the 3 mars II 4oow would suite your needs well.

I had similar beliefs in my tent, more lights at the smaller sizes equaled more custom height control for individual strains, as well as made sure to cover the area with more than enough light... I think 2 would have been ok, but might have been slightly lacking, but 3 for that size is perfect. :) With your grow area being about 1' wider than mine, you may want to consider 2 of the 700w models, slightly larger footprint..and might cover your area slightly better when considering the width..
 
Dear Friends, I have update all tracking number on our website, if you do not get email from our website, please email me and tell me your order number, I will check tracking number for you.

Thank you all and have a nice weekend.

I hadn't thought of that. I am still stuck on the limitation of footprints given the size of the light and the direction of the diodes. Even though a 700 has a few more diodes than a 400 (60 to be exact) is the lite footprint bigger, and bigger enough to provide the same intensity per square foot (2 x 700) than 1200 (400 x 3).

My brain tells me that, with LED's, exact coverage with slightly less wattage can be compensated with lowering the lamps a few inches thus increasing the intensity to the plants with better coverage.

In my mind, a 700 might be so intense that I can't lower them to compensate for the overlapping coverage blank spots. I know I am beating a dead horse, but that is what we pioneers do to lead the way for the top of the bell curve followers!!

I thank you for your suggestion. I am going to run the numbers. You have me THINKING...and, having gone to law school and many other degrees that feed into my thinking nonsense, YOU GOT ME THINKING!!

Thanks!!
 
Can't wait til I get my update and tracking info, ready to rock and roll when these 5 x 400w mars 2 roll in! My 5x5x6.5ft tent gonna be lit up!!!!!!
 
So, with this thought process going on, for the 4.25'x7.0' grow area, it would be better to have 6x400watt lights instead of ordering 2x1200watt lights? And Sara, how many 400 watts lights can you daisy chain together? I know you mentioned earlier you can daisy chain 2x1200 together.
The guy I would be ordering these for currently runs a 1000watt HID on a mover over 8 plants and has an issue with the 4 outside plants(the 2 on either end) not yielding as much as the 4 inner plants and wants better coverage but can't afford the heat of a 2 HIDs in his space.

I think you're thinking is absolutely spot on! More smaller lights to cover a space instead of less larger lights. Makes complete mathematical sense (which is my favourite kind of sense) and I think given the opportunity (and budget) i may have to apply your (and Icemud's) thinking too!

I have an existing 210w LED which I may use as supplementary light if the Mars 1200w fails to cover the entire area! I'm hoping that it is covered, as i would love to grow a ThinkDifferent Auto under the 1200w and hang the 210w vertically and pointed directly at it, would love to see what comes out of that grow!

Do you have a journal? I'd love to follow and see how you get on with your setup and light arrangement when you eventually decide what the best option is.

Happy Friday everyone!!
