LED GROW TEST. 126W hydro grow led VS. 180W pro source LED LIGHT

[mpd]

I think there will be a bigger difference. All plants grown under the same light from the same mother will have that much deviation IMVHO.

No matter what the final weight is, we all win because I think this will prove (hands down) the efficacy of the LED lighting approach. The only downside I see is that these lights need (comparatively speaking) a lot of light distance offset for growing, so this will be a huge factor in growing environments like height-restricted cabinets and that last 10" of bud development would be a HUGE difference in the final yield.

Look at it from where I'm coming from. I'm in the middle of building out a stealth cabinet and it has a total inside bloom chamber height of around 32". If you take off 8" for the pot that takes it down to around 24" of finished plant height if the plants are allowed to bush kiss the CFLs (or fluoros as the case may be) but the LEDs would require the offset so the plants would only be able to finish at around 14" to give a 10" offset. If that were the case, the CFLs and tube fluoros would outperform the LEDs.

Setting that to the side, this is a huge advance for closet growers and would completely eliminate their exposure to IR detection by LEO while dramatically increasing yields at the same time. Less wattage, more bud output and a smaller LEO footprint make LEDs the hands-down wave of the future without a doubt.

cheaper to run by pennies

$425 = 126W
$699 = 180W

The 180W uses 30% more power. Don't see where cheaper by pennies covers a $275 price difference...

I am growing in a 16 cu area. What offset are you speaking about?

 

[irishboy]

My main question is how the hell you answer all these questions when your on almost every forum known to man, lol good work though.

Im sticking right by what I thought from the start. I don't think either light is going to Win or Loose by a mile stone. Four weeks is a real long time to go and I certainly seen plenty of games turn around from the half way mark. Right?

As of now, yes the 180 look nicer (clinch my teeth) but not by much. The bud sites look equal to me, thicker on the 180 side but the same amount. Now that the 126 is done stretching the plant is ready to develop weight and I think the next 4 weeks is going to be very very interesting.

Either way, whatever light does win I bet the winning weight will be no more then 1/4 ounce or 7 grams. Just my 2 cents.

lol its gets kinda hard posting on all of these threads. lucky i got my meds to keep me interested lol.

i don't now whats going to happen in the 3-4 week time frame? allot can happen on both sides. all i really care about is quality, dense buds, and total dry weight per plant. its all about the scale.

i agree that this dose prove that leds can grow buds, expecilay for a new comer that hasn't seen a led grow but heard bad things about them. and i think leds are great for a stealth grower. no exhaust fans or filters to keep the smell from being detected outside. you can also grow large scale crops but just need allot more light. the main reasons why i like leds so much is where i live it gets 115F* in the summer and its hard to keep things cool with HPS. so it works out great for me

I think its about variable change and in this grow the only difference in variables is the amount of power being consumed. Deviation IMO is more or less a growers mistake towards specific plants. Irish no worries man, Im not saying your making mistakes-- you doing great work but all in all I don't think 54 extra watts is going to decimate the competition. Then take account of viewing angles, ratios of different colors and specific wavelengths of light, I think all those variables add up to give promising results and I doubt either light will win/loose by more then a few grams. Sticking with 1/4 ounce.

Also Irish, I do not own Prosource light, however I do own a HGL light so I have a question relating to both. I know on the HGL the LEDs are spaced apart in what I would call a series of light engines or similar. Now with the Prosource, are all the LEDs packed together or are they spaced like the HGL? I think that is something to take into close consideration when evaluating these specific lights.

I completely understand your argument concerning offset MPD but if I let my plants touch my LED light there would be no damage done what so ever. If I took the same plant and let it come into contact with my 68w 6500k CFL it would burn it pretty bad. Despite whatever method of lighting you choice I feel safe saying there will always be an off set to take into to consideration because plants just don't grow contacting the lamp. Offset is all about light distribution for LEDs oppose to CFL and HID, offset is for light distribution, and a means to dissipate heat. I do not kid, plants could touch the glass lens on my light all day long with no damage taken. I don't recommend it but I'm just saying, plants grow a lot sometimes during those long weekend vacations.

today i went into my room with a bad picture. my BD on the PS side that had the biggest buds of all of the plants, had some of my heaviest branches laying on the ground. the main stock was still standing but 4 of my heavy branches folded over with her leaves droped over. i don't know what happen? if it was too much weight or what? i feed her with some B1 and tied her branches back up hoping she will get back into shape by helping her support herself. i am really bummed out, she was my best plant. i hope she will pull threw. i hope she makes it!!!

 

[Bionic]

LST will help with your height probs as well as the offset. Lets see some finished buds. That's really the only missing piece of the puzzle.

That's a bummer man. I think she will been just fine though. She is good hands. IMO if there is to be some positive from this is that those branches just might be a little more potent. I've also had branches fall down. Tied them up and they finished out just fine. Good luck and keep positive. Remember she is in good hands.

$425 = 126W
$699 = 180W

The 180W uses 30% more power. Don't see where cheaper by pennies covers a $275 price difference...

difference in power usage: .49 amps, .054 kw x $.10= $.0054

like i said CHEAPER TO RUN BY PENNIES.

 

[WeedIsGod]

and if you really wanna get technical. 126w is ruffly $3.38 a watt x the 54w difference is ruffly $182. $425+$182=$607. $699-$607=$92. just the facts.

And if one was to buy a 63W panel to get roughly the same wattage as the 180, the watt/$ conversion factor would be worse than that of the 126, closing that gap even more. But who's to say that even if they were exactly the same cost, watt for watt, there would not be a definite winner in performance? I mean, so far we can pretty much say LEDGirl's panel has either more vegetative potential or less intense lumen output causing stretch, right? They out grew the 180W with less power. That either says something about the varied spectrum orientations of the two panels, or perhaps the viewing angle/intensity of light, imo. How many watts are each LED in the 180W? I wonder why the plants grown under the 126W grew so much more. I mean look at the pictures. The 180W looks a fair bit brighter, look at those head nugs, even the popcorn at the bottom. I can't wait to see dried weights.

Hey Irish, on more of a side note man- I think I know what happened to your hurt plant. I distant friend of mine from another land has experienced the same problem. To most this will be shocking but it is something you have to deal with promptly, other wise your whole crop could go under.

Are you ready?...........

............

............

An alien jumped down out of that damn UFO and snapped your plant. Plain and simple. They'll do that every time if you dont keep an eye out. Sticky traps work, medium sized cats, and my personal favorite, garlic and moth balls, all work very well in removing them. Good luck in catching the little bastard(s). Oh god, I pray it isn't plural my friend because if it is, then you have a very very serious issue. Not even the Air Force could help you.

 

[botanist85]

Im not saying you dont, what Im saying is 12 inches is your complete maximum you would ever want to extend the light off the canopy.
So using the light to optimize it the most you are generally going to be with in 6 inches of your canopy or closer. Irish cant do that because everything has to remain fair for both. But someone like me usually has the light at 7 inches and that is a 30 degree model, the 60 degree could get even closer with no problem.

So over all you could probably finish your plants at 20 inches with the right LST. CFLs, and floras give off for more heat then this light does. What I was saying about the no heat was even if your plant did come in contact there would be no damage, alot of CFL will burn a plant in a short amount of time.

Im SOGing my plants, keeping them super short, just one fat cola each and using 22inch max between the light and the plant.

 

[irishboy]

i have heard about this whiting of plants when u have the leds too close. but my hindu skunk on the 126w side is only a inch from the light since she is so tall, and i have no problems with her buds. i cant raise the light and make the other better buds suffer because of her, so led girl just told me to leave it, and now she is forming a nice cola thats filling in real nice, so if anything the closer light is most likely helping her. then again every plant is diff. i also had the 126w 6" from the plants during veg and had no problems at all. thats the main diff i am seeing from these lights the 180w you cant have as close as the 126w.


also someone asked how many what led dose the 180w have and its the same as the 126w their 1w leds.

 

[irishboy]

here are some pics of the fallen plant. the whole plant seems to be doing ok, just the fallen branches don't look like their going to pull threw. two main branches got hurt and allot of bottom branches also got hurt. hopefully those branches will pull threw in a few days. but at least the whole plant ant dead even is she was stressed out of some yield, at least i will get something from her. ill keep an eye on her and see if she keeps growing as normal, or if she starts to lag.

 

[dirtyshawa]

try putting some rooting gel where it's broken and tie it so that it holds.

 

[irishboy]

i was looking at it and it seem that the steam folded over not broke. so i am hoping that this will just act like i super cropped it. if that branch makes it it should just ball up right their.

 

[botanist85]

God those flower look great though, PS is looking damn good.

 

[LEDGirl]

difference in power usage: .49 amps, .054 kw x $.10= $.0054

like i said CHEAPER TO RUN BY PENNIES.

126W x 12 hours = 1512W (1.51kw) x 30 days = 45kwh x 12 months = 540kwh

180W x 12 hours = 2160W (2.16kw) x 30 days = 65kwh x 12 months = 780kwh

780 - 540 = 240kwh per year difference. At an average cost of 10.7 cents per kwh, that's $25 difference per year. But who really cares about semantics except trolls?

By the way everyone, Irish sends me the photos every week as he's uploading them to the web. I went ahead and did some side-by-side arrangements of the pictures he displayed for the day prior to the beginning of 6 weeks, as side-by-side tends to give you a clearer comparison of the plants under each light. Anyhow, here's they are for your enjoyment:
