**ULTIMATE LED TEST** *GLH Spectra 290* VS *Blackstar 500* VS *Hydro Grow LED 336X*

Hey Beef, can they provide a spectral analysis? That's something I would require if I were to ever consider using LED's again. I'm not interested in using LED's right now, but I'm curious if they would provide one.

Well, at this point I have written the panels off. I haven't heard back from Mike despite him having my panels. I made my money back on them so I'm not out any real money, but it's the principle. My internet "marketer" friend is going to have a field day with his site (negative SEO is real), and I just might have to spam all irish's/mike's dickriders at his current forum.

That is totally f'ed up kid. - if I can make one suggestion, be sure to mention his company name in every message so people get it drilled in which one not to buy I'd go to war over some shit like that. Is your grow legal (ie, is he gonna try and call the pigs on you for getting back at him??)

Schwag I don't know what happened with your blackstar (sucks you had the results you had), but mine worked plenty good for me so I could care less about spectral analysis -- I averaged 3-4oz/plant. I wouldn't trust a spectral analysis anyway -- a scammer would provide a fake. IMO, other people's grows who you trust and a company that is reputable to deal with returns properly is all that matters.

Yea I agree with sensi I've had great results with with black star 500 and 900 watt lights
infact i think the plants finish earlier and the resin production seems a lil higher as well

I wouldn't say there was any difference between led and my previous HPS grows other than there was a lot less stress on the plants due to less heat and I got higher yields/as big or bigger buds than my old 600w. No more or less resiny, etc. Just another kind of lighting with fewer heat issues to deal with. My LED plants need cal mag supplementation, but that was about it.

One of the reasons I went with multiple 240ws instead of one big light, besides spreading the light sources out, was that if one went down, I still had the others while the other one was away for repair. It'd be a damper but not a deal breaker. Gotta plan for these eventualities My LED grow is less likely to have a major light outtage problem than any single light HPS or LEd system

good thinking on smaller multiple ones I also go with multiple 900 or a couple 900 and a 500, I did notice that they need more cal mag why is that? do you run hydro? and what nutes you use? I use dyna gro in hydro ( first round with it in hydro) and just finished a round in pro mix, the pro mix girls loved it when i added lime a few weeks into flower. what do you feed at?

No I'm soil and I have not heard a lot of great hydro/LED grows. There's no definitive answer on why the extra cal-mag for LEDs my best guess is that it's the spectrum the lights are at -- very tightly focused at two specific points in the spectrum so I'm guessing the extra energy at those spectrums requires a little more micronutrient support. It also is related to how close you have the lights (plant can't provide enough micronutes to keep up with the amount of energy due to closeness of light).

and speaking of panels out ive had 2 solar storms one panel out of the 4 on the light go out on 2 seperate units. I called george and he had me the lights 3 days later with out me sending the old ones back first! these 2 that went out were from a production line in the fall that i guess had some issues with their heat sink, both are running strong now, he has great customer service!! Ive heard of real night mares where guys leds go out and there stuck, I cant imagine

Sorry for the lack of updates all! My computer died and is getting worked on so I am borrowing a friends on post this.

HPS tent is cut and is drying, I will provide a total yield weight and then average yield per plant. LED Tents are coming down tomorrow!

I'll try to get pics but I cant make any promises until I have my own pc back again.

Hi Juana, excellent journals here. Have you considered the new X5 300W from hydroponicshut??

Thanks! As of recent I have just been focusing on getting this next round going in addition to trying to get the computer back in working condition. I have not had a chance to check out the specs on the new lights but it will be high on my list of things to do once I get my pc back!

Thanks for the question/info!

yeah seen this...like how they say"worlds first true 5 watt panel"...it's like lumigrow and CLW never existed.....big lol at Ben

I have grown great plant with LEDs without cal-mag, I 12/12 from seed so maybe it makes a difference, or my supersoil is good. I have cal-mag, I have used it a few times as a preventive measure but not on all the plants and I didnt see any difference. This next batch of supersoil I will water the soil with a little bit of cal-mag before it cooks but I won't be using it at all during the grow, just plain water is working wonder for me right now.

Here is an LED update for the WJ site while his computer is down:

Beautiful pic!

Pretty crazy grow going on here....

I tried to read it all but I admit after the first couple hours I skipped around to see all the results. Can't wait for the results from this latest trial!

Wejuana you are my hero for doing all of this research.

I learned to build PCs long before I learned about getting stoned, so if your computer is still down I'd be happy to help if needed.

I was happy to see the 600W HPS still "won" even if it likely used double the wattage to get there.(especially once you consider AC cost)

I'll definitely be looking into those Blackstars..... so tempting.


Also to add my personal experience to this mix - the first time I ever participated in a grow we started under CFLs and after vegging for like a month it was obviously not enough light.... the plant had grown fairly tall but not much leaf mass. So in all of our subtlety we figured a 1000 watt HPS/MH would perk it right up... Pure miracle grow soil in a 5 gallon bucket. Surprisingly it didn't even mind the change in intensity from a few CFLS.... to 1000 watts. We had a good cooling setup so that was not an issue. The plant was grown from a germinated schwag seed.(it was the only easy access seeds we had, and our friend had said the grow mattered more than the genetics) So anyway schwag plant took a good 12 weeks to flower, and we had MASSIVE PH problems that we had no idea what to do about.(so we did nothing) By the end of 12 weeks of flowering the plant did not have a single leaf left, all withered died by eight weeks, and the die off began shortly after starting flowering...... So anyway yes we grew buds on stems for 4 weeks under a 1000 watter..... The plant looked like it was begging for death, and when we finally cut her down we considered it mercy.

Anyway that grow with all of it's massive fail yielded 8.9 dry ounces of bud, and in fact it looked 1 million times danker than the headache inducing schwag it was descended from. This was all from dumb kids just trying to make a good grow with basically no serious research, and in my opinion it ended fairly well. Yes we nearly killed our plant, used miracle grow, stretched it, stressed it, heck we even picked bananas off that bitch like crazy from all the stress what with the whole plant dieing during flowering.... The bud was fairly light and fluffy but still had a good smoke to it and I didn't have to use way more to get my fix than any other decent bud I could buy around town. It cured up real nice and plenty of our friends were trying to get some, but we were all about keeping it !

So yes people don't lose hope even if your plant looks in poor shape, all that means is that the next one will for sure yield more, it doesn't mean your current plants are screwed.... I mean from my own example your can herm your plant, over water, over nute, over PH, and if your plant still has the right temperatures and gets light every day you will likely still yield something for your trouble.

Did it win? I thougth LED won on g/Watt, HPS just had the highest yield due to higher wattage... but I'm too lazy to go back and double check...

hey wejuana where have you gone? we all waiting for updates

the threads dyeing by the looks of it, where have you wejuana gutted your not hear to update and show us the results

My Kessil Results:













It works! LED definitely needs a different nute regimen
