Holy f Spuzzum....thank you...thank you. Everytime I mention that heat sinks are there for a reason I get slaughtered by the Blackstar boys....lol

Who make your 660nm's? Don't tell me its CREE :-)

I got them from China..

Cheap, but I couldn't justify $10 a pop for LedEngin's

Especially when LedEngin states that they are 5w.. though they don't tell you that's at absolute maximum ratings. They usually label these things by the "typical" values, not the maximum. So, when you buy an led that states "5w".. well, you'd think you'd still be able to raise it a bit. But if they're labeling at the "maximum".. anything more and your bulb's going to die.

LedEngin also has the 735nm InfraReds, but the same ratings.. and you need to order 223 of them at a time.. at $7.30 each!:

But this guy has some coming in February.. $7 each for 1w units:

As for optics... anytime you put a piece of plastic or glass in front of your light.. be it an air-cooled hood, a cool-tube, or a lens in this case.. you lose lumens and intensity. Best to just buy led's with 60 or 80 degree angle to begin with. .. Unless you just use mirrored reflectors.. $7 each. The guy at ledgrow.eu "had" the lenses, and chose to go without.. these are the reflectors he's still using though.. $7 each


http://www.ledgrow.eu/diy.html


If you look at the pattern of a Cree XR-E.. the ones I'm going to buy, they're pretty much in the 60 to 80 degree range already. Yes, they're rated at 100 degrees.. but look at how far a distance that is before it "flares" to 100 degrees. And then think at how close these dealers are telling us we need to keep the panels to our plants.. what.. 8" to 10", right? It would seem the Cree's are in that range at that distance.


These are the guys I'm going to buy from for my led's:
http://ledsupply.com/


Lastly.. all I can say about dealers..

Not to say that Blackstar, or any other company, is a scammer.. but the marijuana business in general, has always been full of scammers. And for a company that you deal with over the internet, newspaper, magazine, or any other form of "business" that's not "face to face in an actual store/building".. you're taking your chances. So what if they have a 3 year "guarantee".. will they actually still be around in 3 years? Or are they the same "run and gun" type of scammers that told us 1/4 watt 5mm led panels were the future.... ;)

Even if the dealer says Cree, and even if you open the panel and the stars say "Cree".. doesn't mean it's really a Cree.. counterfeits galore in China.. the home of the manufacturers of these panels. They may be North American company, but a lot of them still get them made "in China".

That's why I'm building my own.. at least I know what the fuck's inside. :-P


Cheers man.... :)

Well when you get it built I am totally subing that grow. Kudos for doing it homegrown. I looked into building but I guess I had enough of building electronics in my lifetime :) I really like the idea of those reflectors instead of lenses, I mean why give up 10-15% of your light.

The internet sure can be sketchy but face to face doesn't exactly cut it anymore either. I have a friend who works at a grow store and they carry LED's but they've been told straight up by the owner to discredit LED's and talk people into HID because their jobs rely on repeat business and bulb sales are big money.

When I phoned 357 the guy was obviously a grower and a Canadian and according to Michael Moorer Canadians aren't out to get anyone so I must be safe :razz:

Anyway somewhere in this thread I'm supposed to grow some plants with some LED's. Whether they are top grade made by good old red-white and blue blooded unionized North Americans, or second class electronics from those same Asians who brough us crap like Sony and Toshiba.....I guess only time will tell :mrgreen:

Nice garden bro! Looking niiice. I see temps at 83.3F and ppm meter.. you using co2? What was the ambient temp before the lights? I'm thinking of co2 myself, using a 20oz paint gun cannister.

I'm jealous, and can't wait 'til mine's built so I can play too! :D But I think I need to rethink mine.. turns out Cree's are really 3w'ers.. not 1w'ers. Well.. 2.5w actually.

Can't wait to see what you end up with. :D


Cheers......

Day 23 of flower. Gotta get picks up a little more regularly. It's a bit late in the flower period to trim but I'm gonna get rid of some of the salad on the bottom tonite and post pics of that tomorrow.

Well if I dont have CO2 and I'm at 1100 ppm I'm breathing awful hard...lol

CO2 is propane burner. CO2 is set at 1100 and varies between 1000-1200

Room temp with the lights off drops to 70-75 depending on the outside temp right now which varies between -25C and 5C.......Alberta weather :roll:

From the looks of it dunit it seems those lights are penetrating the hell out of that lower growth so it will be very interesting to see how that popcorn turns out man! good job bro cant wait till harvest!!!
dunit said:
Thanks! Was gonna give them a trim job on the lower parts but letting them run au naturel to see how the popcorn turns out and to see how well these lights penetrate.

Yeah it's sure gonna be interesting....was just over checking out Irishboys journal and he's about a week ahead of me in the same sized area and running double my power in LED's so it will be interesting to see how big a difference that makes. I thought I was a bit overkill on lights but apparently I'm no where near....lol

Think for ease of comparison I'm gonna try to make my first three pics in every set be from the same perspective. Would be good for time lapse later.

Hello chaps newbie here. Am very interested in the mag grow lights myself. Any ideas who makes there leds if they bridgelux dont make all the colours themselfs. Also are they currently out proforming your older led panel in flowering. Also wood you say they live up to there hype? Like i said only just signed up here so havent been able to see ya picts. But followed this journal month or so. Am also very confused by claims online that 3w leds dont increase penetration to the 1w leds. Read one watts best then hear 3 wats better. Wood like to no if any1 tested a 3w led and 3 1w leds c which penetrates distance better. Anderstand that 3 1watts are more bright but does that mean light travels further. My english brain aches with these questions. Any ways cool journel matey good luck with it. If anybody can help me please do so

me again. sorry be a pain in mids off your grow dunit. wanted to say i almost brought a mag 357 month or so back but i was put of cos they use 3w leds. I have read alot about leds and most info i get is 1w leds best fo growing smokeable herb. I no 3 w leds are brighter then a 1w led but i also hear 3 1w leds are brighter like wise. this makes sense to me but where i get lost- is there any prove that 3w leds carrys light further then 3 1w leds. if so can u send me a thread please. If 3 w leds do penetrate herbs better then why are the companys making these units not showing say 2 300w panels one with 3w leds and 1 with 1w leds side by side growing tall herbs showing final outcome i.e final dry weight, thc . and size n thickness of bud. if this was done using tall plants you could or should be able to see the difference in penetrating by the lower buds. but all ive seen are srog or scog set ups which are used so penetrating not big issue. I mean i dont no i am new to this but does anyboby no the truth to these things i said. i just wanna no asap so can buy led and get started but be convident with the light i pick and its tech.

oh and forgot to make test fair the two led panels wood have to have same led maker i.e cree or bridgelux also same lens and same height of tops plants and the sane band and spec, i guess???????? anyone out there done this or seen it? wood answer alot my hang ups. only difference should be led wats i.e 1w or 3w and guess that the 1w led unit wood have 3/1 more leds.

Bottom line, you need 3w leds for penetration in order to produce dense bud. You will end up with airy bud if you use just 1w no matter how many of them you have. Check out my first LED grow using leds that have a combination of 1w and 3w LEDs. https://www.rollitup.org/general-marijuana-growing/378470-confined-space-850w-led-master.html
