Led Growing Is The Way Of The Future My Friends

So... who are you talking to?
Nobody mentioned anything about a 250W HPS comparison.
The actual wattage of his Blackstars and expectations from them were already discussed pages back.
You're talking to yourself on the internet, again.

Let me tell you something Karma, you're a complete troll and a bit of a dick to be honest.
We were trying to help another member and you just keep blocking/flaming us for some reason.

I told him his panel pulls less than stated incase he didnt know, I also tried to find reasons why it would be something else NOT his panels that are the problem.

He said he grows already but its too hot during the summer, what do you think he normally grows with? The Force? No its obviously a HID, hence I made HPS comparison.

Seriously Karma, learn to play nice and not be so bloody sensitive, even Curly and a few others clearly saw I was sticking up for the LEDs there.

Its not all about you on this website, so how about cutting the unnecessary and stupid bashing of everyone who even mentions the three letters "HPS" in here and maybe try help some people out?

EDIT: And even with a faulty panel, the plants should still have started flowering...Even plants left in complete darkness for a whole week will flower.

Sorry to interrupt the argument. I just read all 70 pages. Someone mentioned a CMH bulb being even more productive than HPS. WTH is CMH. Obviously a metal Halide of some kind.

Thanx. Carry on

I'm seriously starting to believe it's one of the panels.
Let me run my scenario by you and see if it's the case or not.
So you have 6 plants lined up under the 2 lights.
Now you said none of the Jillybean's have flowered and that only 2 of the 3 Blue Cheese's under the other panel were flowering.
Let me take a guess and say that the single Blue Cheese that didn't flower was in between the 2 panels (so it was exposed to both lights) and not on one of the far ends, am I right?
If I am, I hate to say it, but it would seem their is something wrong with the panel over the Jillybean's.
At this point, everything else has been ruled out in my mind (based on the presented evidence).
Because if it was stress, the other 2 Blue Cheese's should have taken the hit too, but for some reason didn't and have flowered.
You've got one good panel and one bad panel, but you should still be under warranty though (1 year).
When you get in touch with Gotham Hydro about replacing the panel, make sure you let it be known that you are actively updating other growers about your Blackstar experience via this thread.
It should help keep them from giving you any shit about a replacement (not saying they will, but just in case they do).
Good luck.

First thanks for everyone chiming in. the one BC that is not flowering is on the end and would get know more light from the Jilly Bean light than the other 2.

I do realize that the Blackstar is not a true 240w that output is about 1/2. My goal was to product about 2oz under these lights and get a head start on plants that would finish under HPS. So my expectation is low.

I will contact Gotham about the light. Just reluctant with the nature of things. May be it will help. It just hard to understand . 12 hours of darkness is 12 hours of darkness. They should be flowering regardless of light problems. It just doesn't line up.

But again thanks for the input I will keep looking and up date.

Ceramic Metal Halides, they're basically even better spectrum Metal Halides with the intensity of a HPS. Problem is they only go up to 400w and only work in magnetic ballasts. But Iv seen some real crazy yields on here with 2 400w CMH's, they get the best of both types of HID lights.

Hey, I've been checking out LEDs for the past week, looking for something that won't cost me $500+ and i've come across a few sites offering products that seem like they'll do the trick.
Here are the links, could any one give me and advice on whether or not to trust these?

Not too sure about that first link though.
Anyway, thanks

Put up a link to that grow please, I would like to see the CMh's in action..ta.

I cant find it on Google or the search function, but I think it was Riddlem3 or one of the other old schoolers that runs it...theres loads of threads around the web with many people claiming 1lbs dry from a 400w CMH tho.

This is all neither here nor there tho, lets keep this thread for the LED's.

(Did I actually just say that, lol )

If the light spectrum is wrong they wont flower. So i think my first guess may have been right. I would follow @badkarmas advise and try to change out that light under warranty.

Figures. I've got two ballasts. One Lumatek Digital dimmable 1000W ballast and one OLD skool (ied plugs all around) magnetic HPS ballast. I guess I can't try out the CMH with more investment. Doing more research.

I'm gonna start a thread on CMH, where to get 'em, etc.

Thanks.

Plants will flower under any PAR spectrum of light,do you think the entire planet receives uniformly coloured sunlight?

I was going to guess maybe you got a couple bad seeds, especially since everything else is growing properly.

Try cut it back to 11 hours light and see if they flower,then if not try 10. Some strains/phenos won't flower under 12 hours light.

Here`s some reading for you. I used a quote to explain it better.

Lack of Full-Spectrum Light

• Providing your plant with only a single source or color in any shade can cause harm to the plant. Natural sunlight provides the full spectrum of color that a plant needs to grow and flourish. Eliminating one type or color of light from the spectrum can cause a plant to become stunted in one way or another. For instance, a lack of red or blue light exposure could cause a plant to produce only small flowers or not bloom at all.
  
  

A cannabis plant will bloom under any PAR spectrum...plus your argument above kinda screws LED lights,as they have the narrowest and least "sunlight like" spectrum,but still seem to grow great cannabis.

As long as they are recieving ANY PAR light they will photosynthesise and flower (given the correct photoperiod). People have and do grow under MH and HPS which have a low PAR value and they still grow great plants.

So basically, if his panel is putting out any PAR light at all it's not the panel stopping them from flowering,there has to be another factor.

LED users, please take a moment to add a comment to the thread linked below. It is a site request thread to create a subcatergory for led lights in the indoor forum. Thanks guys

Yeah I reset last night I don't know why I never thought about it before but I hope that will take care of it.

Kewl, so i can grow shit with my xenon headlights, there PAR lights.

PAR stands for either "Pressed glass Aluminized Reflector" or "Parabolic Aluminized Reflector," depending on who you ask. Has nothing to do with growing.

your right, par can stand for different things... but for plants its Photosynthetic Active Radiation... pretty much the wavelengths of light that plants DO use. Its incorrect to say " they will flower under any par spectrum".... a plant will flower under almost any wavelengths of light, but without that red your going to have some skimpy bitches.

To address your earlier post first, how is it trolling if I'm keeping you on topic in an LED thread when you keep wanting to talk HPS when nobody else is?

Now for this post, wow, really?!
Tricks posted the correct info for you about light spectrum's and you kept on going like it wasn't there.
Seriously, if your trying to contribute to a conversation, you usually have to acknowledge what the other party has said in order to continue moving the discussion forward.
Otherwise, you're just talking to yourself on the internet.
If a cannabis plant will bloom under any spectrum, please get some older incandescent light bulbs (not CFL's) and bloom me a plant with some decent buds.
Why didn't anybody think of that before, we can use any light source to grow and bloom our plants?
I don't even know why you'd use an HPS over an MH to bloom with then, people who switch between them from veg to bloom are so stupid, what are they thinking?

Obviously those last couple of statements were made for dramatic effect to prove a point.
It's not trolling if you're right and can state your point, it's called being a smart-ass.


Now Tricks, I have to correct you on something too.
The PAR that has been discussed stands for Photo Active Radiation, and not the terms you were suggesting.
Here's a link all about it:
http://en.wikipedia.org/wiki/Photosynthetically_active_radiation

He technically is right, a plant will flower under any spectrum, but it will be SHITTY ass yields.
