Mars-Hydro LED Grow Light Discussion

ok peps update here,..

so today i get a call from my buddy to come over. on arrival he ushers me to him grow room. and there hanging was a MARs 2 700 watt.
i can tell you this this is BRIGHT. it over powers the light given of from his 600 HPS so i will watching his next grow to see how well this light does.. ps it is built like a tank

just my 2 cents With led v scrog is a waist of time, nutes and light.
led panel is flat
hid light is round

I agree with this 100%. I will be scrogging with my LED panels but just by the physical nature of the LED lights i would think a v-scrog is unnecessary... and possibly counter-productive.
 
Ok....I get it now. So I can do a SCROG with led lights cause of the flat surface the lights put out. Hell I didn't know there was a scrog and a vscrog lol
 
Happy New Year And Happy Grow For 2014:circle-of-love:Thats was great holiday with my family And thanks for everyone help me reply questions :thanks:I have good news for you, our container already release from custom, tomorrow will delivery to warehouse 7th will get ready for your order shipping. Please make your order on website,Best LED Grow Light available for you:welcome: these days really hot sale i worry will be out of stock soon

I know not enough tech info but basicly
light foot print of an led - all light is directed to a specific angle 90-120 and creating a flat square
HPS light is emitted in the round shape of the bulb creating a u shaped grow space.
A vscrog with LED would require 2 led panels hung in a v of matching angles to the screen

Thanks, U just verified what I have been looking up - Appreciated

I don't agree with this at all. (no offense). Square inverse law would make this statement false. Either light, led or HID is going to lose intensity the further away you get from the source. By bringing the edges of the screen upwards (where light intensity is weakest, HID or LED) this counteracts the square inverse law and increases intensity delivered to the foliage by decreasing the distance from the source. This can be seen if you look at PAR reading charts on HID or LED lights, the intensity falls the further you get from the direct lighting, as well as the further the distance from the light source.

Also by raising the edges of the screen you are creating slightly more surface area to "scrog" and therefor more room for tops to develop.

I also don't see how LED and a Vscrog would waste light and nutrients? please explain your theory. I'm curious to see your side of it. (and please don't be offended or agitated, I'm curious what lead you to make that statement) :)

I'm no expert, but wouldn't simply getting the correct light for your grow area, with the correct footprint and wattage, negate the need to v-scrog with a flat panel LED unit? I agree with your point in principal, but unless (for example) someone's gone for the 1200w with 4x4 footprint in a 5x5 grow space, surely a v-scrog isn't needed? I also see your point about the slight increase of surface area with a v-scrog, but conversely, i would think it slightly reduces your available height/distance from light source, which may be a factor for some people using LEDs.

In a nutshell. wouldn't just getting the right light/lights be a better idea?

Anyway, like i said, i'm no expert, i'm just trying to get my head around this one! :)

I just watched your 2-part v-scrog YouTube vids and wanted to compliment you on getting the most out of a 2-plant grow. The setup is simple and efficient, and you make it look really easy. I've been planning to LST my next grow, but might get energetic and build a screen now... :welldone:
 
Icemud.....i just found your YouTube page....man o man i have been needing the visual side of the information.

If I got questions as I get going would u mind if I PMd you for info? ??

Sara, I am looking to order 2 900w mars2. Do we still get the 420 magazine member offer first given in this thread?
 
Got my light today :) unboxed I give her an A+, super bright! I have her hung about 1.5 feet about my ladies. Thank u Sara! Hope she does the job well, got 2 la fruitta devenus who are 85 days from seed, almost finished ;) also a baby sitting under it, started under cfl she is a week or so into veg and doing wonderfully. All goes well decided to order the 96x3 and te MarsII 400. I really like this light, packaged very nicely, blindingly bright and feels sturdy. Also very cool the round about hour I've had it running.
 
to me it seems way too obvious.
Any flat scrog grower can tell ya hps light the outer edge stretches to reach light
for the life of me I can't find the demonstration of HPS vs Led that shows this commonsense
Using a spectrometer lights of comparable foot print hps fades out in the round shape of the bulb/reflctor, and led panel fades out PARALLEL to the panel .
Put them side by side and it can be seen by the human eye.
:peace:
If I must waist the 2-3 hours looking up commonsense info I have used enough to not notice the fact that I forgot it and others might need some hand holding.
the simplest way. look at a 6" square and a 6" circle on there sides.
The physical nature of the 2 lights supplies the commonsense answer

Yeah you can PM me, comment on the videos or even as questions in my journal. I don't have all the answers but I will try my best to help.

Thanks Bolivar! It actually was 6 plants total in the v-scrog but I definitely got a very nice yield each time I scrogged. Averaged about 3-5oz in the scrog per plant vs about 1 1/2-3oz per plant growing them tall. Definitely went back to the scrog because the yield was that much better as well as was more fun to grow :) LST works great and I use it a lot before putting my plants under the screen. Also I have been doing a lot of supercropping in veg and my plants respond very well to it :)

Thank you for your reply... I appreciate your time, and helping another member understand something is never a waste of time. We are all here to learn and grow as a 420 proud community. Even though I don't agree, I wanted to see your reasoning behind your opinion and I appreciate it.

Just to let you envision my idea better, regardless of the "shape" of the light output, we both can agree that with either shape, intensity is lost on the edges of the light footprint. Both LED and HID, as par test comparisons show this effect. Now when working inside this footprint (whether circle or square), due to the square inverse law, each time you double the distance away from a light source, the intensity goes down 1/4. So directly below your light you are getting much more Par Umol/lumens than on the outsides of the light footprint. So like I mentioned, regardless of the "shape" of the output, with both lights dimming near the boundary of the light footprint, wouldn't it gain intensity by bringing it closer to the light due to decreasing the distance to the light source (within the light footprint)?

This is the way I see it, right or wrong, to me it makes perfect common sense as well. Either way I appreciate your input and hope that my more elaborate description also explains why my theory isn't so far off either. Either way, v=scrog or scrog or whatever, Lets all grow some dank and medicate the world! :) peace my friend :)
