STAY AWAY FROM LED's!!!!!

collective gardener said:
Bob, very perceptive view on HID. Power is just another operating expense. Proportionally, it's really not that much...certainly less than trimming costs. But, speaking of bottom lines, IF the LED could produce HID quality/quantity buds, they, too, would pay for themselves quite fast. The higher cost would be offset easily by lower power and bulb replacement costs. These people that keep saying that folks are not buying them because of high cost are way off course. People are not running out and buying them because they simply don't perform as well as HID. And, nobody wants to spend ANY money (let alone more money)for a light that can't do what HID can do.

Your point on heat, Bob, is certainly spot on. Heat is the bane of my existence all summer long. This weekend I'm installing another sub-panel to power the new A/C unit I ordered. This is all in prep to seal the grow and stafrt with the CO2 enrichment.

EXACTLY! LED just doesn't deliver the type of quality and quantities that HID's do. Don't get me wrong, I've seen and smoked some great LED bud, but it falls short compared to the product I get out of my 500w HPS cab.
As for the heat,I feel your pain man...I live in the tropics, and it's near impossible for me to get my temps below 80 degrees with the lights on, especially with the open reflectors that I'm currently using. I'm hoping to get my hands on some air-cooled hoods, or possibly DIY some cool tubes!

Seems pretty snippy to point this out when the guy changed it.

OT : For someone like me, who only needs to flower like 2-3 plants at a time to keep up with my needs, I think LEDs have potential. But I also agree that at this point, for large operations, they're not even close to practical. But that pr0fesseur has a neat thread up showing even more alternatives. https://www.rollitup.org/indoor-growing/358190-led-without-leds-my-first.html is what I'm talking about. Where do you think this weighs in on the heat/growth scale for small growers?
 
Used my Led panels plants will grow but streatch, they do work wonderful for cloning, used one panels all cuts rooted nicely. They should only be used as supplemental light. They need more research and development.

Earlier in the thread, I mentioned my desire to build my own LED panel to test. In one forum (I linked it on the last page), a member said that the blue light spectrum enables the plant to control it's internodal length. What do your panels look like? What is the apprx. red:blue ratio?
 
so far.....

Known Pro's:
-electricity consumption
-heat
-Light Spectrum (up to 5 Band lights, red,green,blue, UV/B, and IR)

Known Cons:
-Light intensity (most can not equal a 600W HPS let alone a 1000W)
-PRICE $$$
- Quality. most brands, and even some major brands produce very poor quality lights.
-Measured in PAR and not Lumens.
- they needed to be so close to the canopy (Clonex's Study)


My hypothesis thus far is as such:
LED Lights are Very good for cloning and vegetative growth if an individual can spend the needed money to acquire a light of sufficient quality. with the electricity costs lowered, heat output lowered, and clones produced over time the light should be able to pay for its self within one year to be a quality investment, saving an average of $30/month on electricity with the combined lower cooling needs, and lower heating costs, putting out an average of 30 Clones per month at a cost of $5 per clone. over one year this would equal roughly $2100~ and would pay for the investment in a light up-to $1500 Easily.

Flowering Growth for LED lights is another story. LED light makers need to start measuring the individual Lumen output of a single Diode. 5W Diodes are starting to change the game, but without this Vital Measurement we will never truly be able to make a light with the intensity of an HID Light using LED Technology. in 2012 there are many 5W Diode models coming out, many of which do NOT list the lumen output of a single diode, or the light as a whole. they use PAR to measure Light intensity, which is not a Useful measure when dealing with PLANTS, its only useful when finding the total energy which is displaced by the light, NOT the USABLE Light given off by the Diodes.

with a proper spectrum mixture (Red,Blue,Green and UV/B), and the proper Lumen Output (Of 10,000 Lumens, per plant for flowering...) LED Lights could have a spot on commercial growing in the future. untill that happens Commercial growers will be Forced to grow with HID Lighting.
 
bongsmilieHey Corbat , just 1 point , i would say they can-not cover a large area and add it to known cons - they needed to be so close to the canopy in my test , and this vastly reduced the coverage area and amount of plants that could sit under it , any higher and they hardly worked at all ...
 
I am also wondering this , it is true that the wattage consumption on the early Led panels was very low - and they did not work nearly well enough, the wattage power of the latest panels seems to be rising somewhat to say the least , where are they up to now 500w or so ...? my thinking is , by the time they get there , they will more than likely use alot more power so maybe there wont be much saving on power consumption at all , also if they are powering up more are the bulbs changing also ? do they still last as long ? will there infact be any heat issues ? im starting to feel like you should hang above your plants the brightest light possible despite all the science , also all the overpriced led panels that were overpriced like crazy and did not work , are they all in an LED graveyard somewhere or are they infact the new style 1's in a frock..........
 
:D that does make alot of sense. im hoping if they make the tech better they will be able to cover a HUGE area of plants :) but i think thats what growers have been dreaming of since the 70's haha.

Lmfao dumbest post of the day? wow Mr my mommy doesnt pay any attention to me so i come onto the forum and wave my Epenis around and try to look cool.... thats a Big claim from someone like you.

BTW what you ACTUALY said was

and if you take the Context you put it Into "UV Lights, Thus LED Lights are BAD for you", the context means you were saying a MH was better than LED because it has no UV/B lighting.

on the Contrary, LED's are actualy BETTER than MH on that factor, UV/B Lighting. i have to add 2 aditional bulbs, per Square meter to actualy equal the suns UV/B Spectrum in my MH and HPS rooms.

P.S: Next time you try and argue with me, actualy present something legitimate.... dont just spam "NO THIS R WHAT I DID".

Edit:
I eat Jerkys like you for breakfast. Learn English.....please.....

no actually i MEANT WHAT I SAID.....Just becaue you take plain english and think it means something else dosent mean it means something else like i said i CLEARLY said that Mh dosent give off alot of UVB rays and when you use a hood with glass you loose ALMOST all the UVB rays.......so how the f**ck does that mean led lights are bad for you ??you need to learn english you dumb ass....... do i need to say it again .. ok i will........MH does not give off alot of UVB rays and when you add a glass hood to it it almost filters ALL the UVB rays out thus meanings you dont get alot of UVB rays form MH and if you are using a hood with GLASS you dont really get any......lol

Why dont you read all my comments before jumping in ? i have used both - my comments are sensible and i will debate what i like....

Well,

It didn't take long for another LED titled thread to turn to shit. Prior to this bombardment, we were actually having a reasonable discussion. Then, it's he's a jerk, you're a jerk, he's a bigger jerk, you like to jerk, jam it, ram it, cram it , slam it. Holy fuck guys. It's a fucking light! What's up with all this "you said I said this, but I really said that, so you're a bigger jerk". My god. You kids enjoy this sandbox. I'm gone.
Click to expand...

every single LED thread will turn to what you just said and this is why...LED growers are the most snobby stubborn jerky people on the thread.... anyone coming in saying ANYTHING other then what they think they will attack them....this is the main reason i come in here is to prove my point........i say one thing agaisnt LEDS and everyone start calling me a trol and attacking me so then i stay just to see them destroy there own topic....its kinda funny really.....if you go into any other thread and leave an aposing view point no one really carss or freaks out but in ANY led thread they freak like no other........ we have gone over this before and its common knowlage now....

foot clan has done that to pretty much every led thread on this site. Still, this was one of the better discussions I've shared. Still pretty easy to read if you add him to your ignore list.

no what you mean is footclan has been out numberd and picked on for simplying posting a view point that differs from your own.then when hes attacked hes fights back......this is what you really ment and this is why you must put me on ingore because you are too weak minded to debate me with logic you can only ingore me because thats easyer then having someone tell you your wrong about something.....lol weakmind you are.....sad really
 
Clonex said:
This is exactly my stance , i have a large area to light up , i have even looked into haveing some panels on runners and using them as side lighting , but its either a 2000$ panel that works or the other crap that dont do the job, Hoss makes alot of sense with his comments , we all want the benefits leds obviously bring , 1 - i cant afford 8000 bucks 2 - i dont feel i will get the coverage ...
Click to expand...

i can afford i can afford a dozon of them but still dosent mean thats the only reason not to get them....just saying theres more to the problem then just cost.....i know i know im only a troll and nohting i say is true ......lol
 
virulient said:
Just want to add. If you bought a 20 dollar LED panel off eBay and it didn't work.......don't respond with "I USED LEDS AND THEY SUCK". You need to research a LOT more, go buy a proper light, develop some kind of input valuable to the conversation, THEN make your comment. This thread should be like 2 pages long right now -.-
Click to expand...

yes and as long as your comment is PRO led then we welcome it.....you forgot the last part so i added it for you.lol

my thought exactly i love to use them for my clones and cutting......

Sides dont matter , valued information rocks - if you have something to add - do so - i just do not see the need for "Aggressive Typing" even if i agree with some of your points -
