I use LEDs in my tents, all veg use em and some flower tents. In my big open area I flower in I use the 315s.
I noticed that for some reason I have to add more Cal mag under the led. Anybody else experience this?

Greenthumb seeds says he has the arcata cut and is what I have the S1 from. If it is I don't know. But he usually says what he says it is.

I bought a single cob light a couple years ago and I was disappointed with it. Super bright but also super hot. At the time I had it in a small tent and stressed the hell out of em from the heat. I didn't build it but bought it. Don't remember what brand. But only used it for a week.
Led is the future for sure but the game is changing faster than the flavor of the month for weed. Lol seems the newest and better chips come out every other month.
How much would it cost to build those cob lights to cover a 8'x 14' flower area?

I found his journal here on RIU. Scanned through it real quick and saw a 24.4 level. All the pics are gone except for the last page where he reloads some pics back up. Looks identical to mine.

Thata all dude kept saying is he likes the pine smell. He's after the piniest taste and smell
Idk man I bought some of the old cxa3070s on hlg 185s then picked up some cxb3590s and same 185 at 1400ma , so 12 of the old cxa's and 8-3590s and they wouldn't cover much more than a 4×4, well 4x5 actually, I had them every square ft I think. I ended up taking them down and running the 315s, and the ceramics did better but I still wanna get all 3590s and see what's up because with the 3070s being lower output they were used when I got them too. I think they would be pretty close, but the real advantage is the efficiency, with less power usage and heat that'll be my summer setup. Then back to the 315s for winter. But with all y'all running those strips and talking highly of them got me wanting some.
He'd probably like that 79 xmas bud.

If you figure out how the f!ck to do that, please let me know.

Also, here's a good place for anyone to start on the strips.
http://ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/
However, due to the time involved and the hassle of putting strips together and adding heat sinks, I found it's much easier and cheaper to just go with some hlg boards like the QB132. The V2 versions have the latest top-of-the-line diodes, the LM301B, and they don't require heat sinks.
They run about $125 for four, which will cover a 2 x 4 area with the HLG-320H-36A driver ($85). Of course, the more boards you run per driver, the more efficient they are. But, with the wiring and aluminum angle, that's about $240 for every 8sqft.
That's around $.80/watt, and just as good as any cob. Cheaper, and preferable, Imo, with better coverage.
I'm just mentioning those as a better alternative to the strips, but if you're filling out an area larger than a 4 x 4, I would just go with the latest and greatest QB96 Elite V2s. $99 each with heatsink, run every two on the HLG-320H-54A for every 8sqft.

Sry to hi jack your thread @Heisenbeans
@Greenthumbskunk
It's a completely different ballgame with leds than it was 2 years ago. Hell even a year ago. They werent this good. Right now you can get plc photo boost strips for like 26 bucks each. 8 of them run on hlg480 driver. Would rock n roll. Or double up on strips and 2 drivers. And you got killer light that will absolutely amaze you.
This light will push 1022watts maxed out. I run jus about 660w dimmed down. And it will flower a 4x4 easy. Built square. But I have it built in a rectangle jus bc of my area is rectangle. But just the lay out just a bit. I have less than 500 in it total. But I also get the strips cheaper than anyone else bc of my job. I work for a sign company. We do led change overs from flouro to leds. So we order a ton of stuff. But even at cost right now. Still better than anything I've used. And I've used em. Quantom boards are awesome too. Samething jus closer diode spacing essentially.
This one is built square running at just a hair over 500w built just like this will absolutely flower a 4x4 area. Like a fukn rock star. Older cobs arent close to efficient. That's the heat you were talking about. Now you can run them low current over more cobs. Less heat but the same amount of wattage.
This is dimmed all the way down for the pic. Turned up it's just a complete blur.
This is a mix of 3k and 4k F series gen 3s strips and H inFlux_L06 strips. The L06s are Lm301b diodes and the f series gen 3s are lm561c s6 diodes.

These are H inFlux_L09 4 foot strips. Double row. Lm301b diodes. 220lumen/w I think. Best strips out in my opinion. 48v. 8 of these over built on a 4x4 frame will probably flower atleast 5x5 maybe 5.5x5.5 they are extremely bright. They will absolutely ruin your eyes they are so bright. Use extreme caution do not look into them without something like method 7 glasses. No joke. Will burn the cones in your eyes.

Each to his own, I guess. I try to avoid pine taste and smell like the plague. That NL pine smell. It's just too damn prevalent in too many strains I've had. I don't seem to like the high associated with that smell.

By the time this thread is at 1200 pages, I think we'll have discussed everything from quarks to the kitchen sink and everything in between... with a lot of killer flower shots to boot.

@Greenthumbskunk right now the cheapest route to do a 4x4 is using Hlgs elite 96s. Two 96 per driver. Two drivers 4 qb96s. Will make that 315 become a door stop. I think you can get them for 99 bucks each with heatsink. And I promise my entire seed collection they will out flower your 315. Probably even dimmed down.you can run each one at 240w max. No need bc they are fukn bright and powerful. Youd have to raise it up. Two elite 96s per hlg320 type A driver. Or max them out with two hlg480 drivers. Be over 1000w. But 640+ watts in a 4x4 is 40 watts per sqft. Would be sufficient. And you 400 bucks in the 96s and about 80 bucks a driver roughly. But a hlg320 will push like 335 watts each something like that.

That is a sweet build!
@Heisenbeans take a look at that whole plant pic in that link he posted.See the look of those bigger leaves at the bottom,kinda broad with that roundish profile to the whole leaf??That is the arcata cut....if it doesn't look like those it ain't the arcata cut.

LED's seem to create a slightly different habitat for the plants. When you get it right, it produces nice flower and a lot of it.
