You are getting the 180 from growhydroled, botanist? I was looking at the size of the boards, and you both are right, for a little more board, you get a lot more led, and we have seen the 180 and its a bright bitch. Too much man, haha, too much! MY eyes hurt and its been hours since i was around led's. Strain....much strain.

Oh ok, so, the XJ13 sounds badass, I been seeking some Jack Herer for some time. With the g13 hybrid it should be a wicked plant eh??

Exciting stuff!

So am leanin towards the 180, but I want to wait for a bit to see what you end up with Irish, and Botanist? YesH?

i should be starting in a few weeks. i want to clean the grow room before i start a fresh grow. a clean room is a happy room. when you starting ur grow Botanist? anyways with my grow and his everyone should be able to see what these leds can do. be kinda nice for me to see what his 180w can do on ur grow. ur doing a side x side to right?
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

Me? I was going to do sideXside, but ended up not, because of failures of a unit, and other issues.

I am in the works of finding a good strain from some random stuff. Long process ahead of me. Thinkin gettin seeds would be easier than going through all this...I am no breeder...

I do have some upcoming sprouts, even with the extra lights from HGL I am still only using my lumigrow and the ps 180. They are side by side, kinda works good! good coverage by both units. Lots of power.

Sorry for the long response, haha, if that question didn't pertain to me, I be sorry!

actualy i was talking to Botanist. but thats cool also, keep me posted on what happen with ur side x side go green.
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

It'd be a good test to see their 180 against PS 180 eh? Then again with the new tech from their end coming out, whenever, maybe I dunno. haha. Almost ready to fire the 250 back up in the tent, but would rather try another brand than go back to hps.

Peace Irish. Can't wait for all this!

Botanist, holla at us bro!

re: LED GROW TEST. 126W hydro grow led VS. 180W

Hey Irish, Just wanted to post some figures I just came up with.

GrowLedHydro has better $ per watt value than HydroGrowLED

GLH as Follows:

120W = $2.91/watt
180W= $2.64/watt
300W= $3.16/watt
600W= $3.16/watt

HGL is as follows:

63W= $4.36/watt
126W=$3.76/watt
205W=$3.41/watt
318W=$3.77/watt

Other conclusions are:

The GLH 600W panel gives the most watt/square foot, then the 300W, then 120W, then 180W. Not what the light can do in terms of area, but the amount of area per light, and the watts which emit from that area.

The values are nearly half the watts per unit in terms of the HGL lights and their size, compared to the GHL units.

You get more watt per buck, and more watt per area the unit occupies in your grow space using GrowHydroLed.

Just thought I would share that. Took me some math, lol, but I won't claim to be a genius, promise! haha

Peace dudes, I hope y'all find interest in my findings, and please spread the knowledge.
Most figures are rounded. If you want more specifics, hit me up, I have it all on paper.

!Go Green!

damn thats allot cheaper, i knew he had better prices but but been too high to do the math. thanks for the good info.
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

I looked at the GLH site and cannot make sense of the coverage numbers for the different panels.
  • 120 has a coverage area of 2.5 x 2.5.
  • 180 is only ~30% larger than the 120 yet it covers ~40% more at 4 x 4.
  • 300's coverage is 4.5 x 4.5 - just slightly larger than the 180, however it is the same size as the 180.
  • 600 is twice the length of the 180 and 300 yet has only a slightly larger footprint at 5.5 x 4.5.
  • All of the lights are rectangular but have a square footprint. The exception is the 600 with 25% more coverage in one dimension.
Also, the Does it Work section (also titled How Does it Work) says that the units have 9 different LEDs that emit 12 wave lengths - some of these must emit more than one wavelength. Is that even possible? I think claims of 11 wavelengths are made elsewhere on the site.

What angle lens is used?

I know he claims that the wavelengths he hits are a "trade secret". I wish these LED vendors would stop doing this. Its easy enough to tell what they are given a unit and a person with a decent electronics background. Saying its a trade secret is like a BMW dealer saying the horsepower on their cars is a trade secret. It can be tested and people generally want to know before they buy.

i don't know about the foot print thing? i think the foot print thing is maybe one unit uses more leds and has then closer together so it makes a bigger foot print? i don't know.
i know the foot prints on the web site are of the older 60 degree lenses and now they use 90 degree lenses so the foot print should be bigger then whats claimed. (don't quote me on this) with the 9 spec leds that emit 11-12 spec color i am guessing its because he uses white witch is a few different colors mixed to make white so that makes it 11-12.

as far as the trade of the secret thing is because if they do have a bad ass led light they dont want other company's taking their nm's and using them. they try to make it harder for other to copy cat their products. even though its easy to take them apart and see what they use, maybe they figure screw it they have to by it to find out at least...lol
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

Its just an annoyance for the consumers and provides no protection from competitors. I have worked in consumer electronics for many years. The first thing we do when we are developing a new product is to get all of the competitors products and take them into the lab and test them, then take them completely apart.

i know bro. only very few company's list their nm. but i guess it dosent really matter anyways because we really don't know what MJ uses. or we would be rich right now. so thats why i never cared, plus i never bought my leds lights..lol i guess that has something also to do with it.
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

do the plants seem to be getting any fatter now that they're close to the end? i took the liberty of ordering a custom light from the same manufacturers they use, why pay middle man prices. i have the 600w mold, using 3w leds, 60 degree lens, 1700w, $1190. the cost for 1w leds was $916 and they said that price was higher than the other manufacturers. it's a good thing you get your lights for free. imagine the price these companies would charge for 1700w.

Care to tell us which supplier you used for your panels?

But telling a customer the horsepower of a BMW doesn't allow him to send that spec off to China to get a similar BMW for 1/4 the price...

i went to the made-in-china website and found a bunch of different semi-conductor companies that make led lights. china is a communist country and the government controls the exports so, your gonna get pretty much the same whichever company you choose.
 
re: LED GROW TEST. 126W hydro grow led VS. 180W

Sounds fishy to me. How do you know what you are getting? What about warranty, returns, defectives, etc? How is all of that handled? Not to sound like I am bashing you, by all means, if there is something out there for us to get our hands on, I would think we would have gotten there already, alongside or before these existing companies.

None the less, that is a huge panel, with tons of power. Almost 3' long aren't they?

How's things Irish? Hope all's well bro! I have yet to hear back from the spectra led place. Maybe drop me a note, let me know how to contact said person.

yea the companies on the market selling chinese manufactured led panels sounded fishy to me too, after i talked to my hydro store guy. he advised me against the chinese made units. ledgirl, told me the only difference from her panels and all the other panels manufactured in china was that hers had a 60 degree lens. so, after doing my homework i came up with the specifications i wanted and probably did the same thing all the other led companies are doing. i found every type of led panel in every color. the prices make sense considering the markup hydro-grow-led sales their units for. all the info i got from the manufacturers in china is exactly the same as the info ledgirl sites. that's probably why the comparisons to the 400w, 600w, etc. come from. here's a pic of the unit and some of one of the emails i've received:

Thank you for your inquiry.

We accept OEM, so we could make the lights according to your special requirements.

Following is the picture for 600w LED grow light:
Specification:
Power: 600w
LED: 576pcs x 1w
emiting angel: 120 degree

That is the specificaiton of the normal 600w LED grow lights.

If you need, we also could make the lights with the 3w, 60 degree LEDs as the light source.
The 25% 625nm red, 25% 640nm red, 25% 660nm red, 10% coolwhite, 15% warm white is also not the problem
According to your requuirements:
Weak Red 625nm 25% 144pcs
Red 640nm 25% 144pcs
Deep red 660nm 25% 144pcs
cool white 8000k 10% 58pcs
warm white 3000k 15% 86pcs

You also could design the location of every LED in 600w LED grow light.
Do you want to design the configuration of the 600w LED grow light yourself or you want our engineer to design it?

By the way, on your design, there is no blue light at all, but the plants' photosynthesis need some blue lights.
Do you want to add some blue light?

I just want to make one thing clear, the LED panels from china are not all the same they may look the same but the internals are not. If you decide to go straight to china and order your lights remember one thing, each one of these manufactures have no idea what these lights can do. I have asked them one after another for any kind of grow pictures showing me the lights work and no one has produced one. This is why I had to order over 20 panels to finally configure a spectrum that works with the right led intensity and find a manufacturer I can trust with a quality product.

Another thing is if your a person that buys one or two panels good luck trying to get a warranty, they'll tell you 'yeah we will take care of you' yeah right! They will say anything to you to make the sale but when it comes down to returning the light YOU have to pay for shipping to send it back and they most likely will tell you that the light failed because of user error.

Im just speaking form my personal experience, dealing direct with china is not easy. Just a heads up for you guys.

--------------------------------------------------------------------------

Oh and btw----- to clear up a question I saw regarding my spectrum, yes i use 9 wavelengths including white which puts out 3 colors RED BLUE GREEN, so that's how I get 11 wavelengths.

Ill send you guys an update on the 90 degree core saturation sometime tomorrow..

Peace...

It is for this reason that we would prefer it be compared to a 400W.

but cant you just use a 600w and the same amount of plants and it would be the same? and keep each plant in the same size area. that way it would be a accurate way of testing the yield since the light is compared to a 600w hps. just keep both plants in the same size area. i am sure you will get allot more respect using a 600w HPS for that side x side test, since customers would want to see if the 205w led light would really match a 600w hps yield as claimed. its just a thought to think about.

either way i would like to see these test, and realy like to see the 205w vs 180w, since it will be diff from my test. now your light has the higher watts. be cool to see what happens.

lol you dog Irish, why you giving HGL a hard time again, that is my job...ha
