How do you run the Osram at 700?

Split the single main 1400ma string into 2 parallel strings of 700.

Would you mind showing in a bit of detail for me how you did that?

(-o+) is osram ssl
(-C+) is cob
(f) is fuse
Two strings of four osrams:
- -----(-o+)-----(-o+)-----(-o+)-----(-o+)-----(f)----- +
- -----(-o+)-----(-o+)-----(-o+)-----(-o+)-----(f)----- +
Tie the two + ends together. Do the same for the - end of the strings. Treat that as a single cob. That's essentially it.
Those two strings together are ------<-=+>-----
So complete:
1400ma led driver - -----<-=+>-----(-C+)-----(-C+)-----(-C+)-----(-C+)----- + led driver.
With a 1050 driver and 3 (strings of) monos in parallel the monos get 350ma, for example.

Digital temp sensor next to each cob, for fan dimming/boosting. Osram ssl stars on a piece of square alu pipe, polished, ~12 holes on each side. Fans on cob heatsinks pull the air over them. Not that they really get warm anyway.
Heatsink for the module (from old pc) fits like a glove in the center gap of the frame. Module is on a separate non-mw driver, relay and remote control button.
With just the center module (~22watt) and flash on camera
Need to relocate that temp and humidity sensor to the side, messing with my pics...
Without flash, purp module only. Will spread much better when I raise it tomorrow after making some space in my closet (lowered ceiling...)
Done for a while till I work out the enclosure. Plants, most in 2L perlite bottles, not too happy with the switch to hps and double the wattage for a few days, especially with global warming finally having reached NL, 90f in Sep... I should have planted plants outdoor...

Now that is a proper grow led. Sexy red phallus too. Very nice job.

Yeah they're loving it. They were on 12/12 for 5 weeks and a few days in those pics. Full on flowering for less than 4. Slowest transition ever. Not from the leds though, vegged and transitioned partly under 400watt mh. Switching between lights multiple times clearly had a bad effect on them. It's mostly panama x silver haze, very stretchy sativa dom, and pck x sh. Pck is a very low yielding landrace kush and crossing it with sh improved that only a little. One plant in there is a panama that was already flowering, as well as a pure hindu kush. Especially combined with having vegged way too long with the 400watter, having removed some males and pollinated buds, it's not the best situation to see what the light can do. I'll be starting a new round with led from start to finish within a month, with several exceptional OG varieties from the US. lol... If you would have told me a year ago I'd be growing OG kush under led in 2016 I would have lmao...
That all said, I'm very happy with the results so far. Plants smell great too. I moved around some panama x silver haze plants yesterday and brushed my arm against a few plants... smelled like I pissed over myself in cheetah form... exotic cat piss haze.
It is obviously not ideal for 4x4 ppf-wise but then my old 600w hps wasn't either. I will add more blue and red over time (i.e. when they get cheaper or newer versions from cree or osram or others), dim the citizens, allowing me to increase both efficiency, output, and work towards a spectrum as sexy as the one above.

I am still wondering if I should add any monos.
They look happy and healthy, I know switching lights can confuse them, hopefully you dont lose much as a result
Interesting strains, not sure about a feline piss smell, but I would have to have it in my tent to know.
I like most smells in plant form so far

Many of the hazes are either incense or perfume, this one is more dank. I think it will eventually dry into something delicious.
The results of panama x sh are clearly not uniform but this one is in the corner, in an already crowded space with roughly 570ppfd, and if I were to need proof of both quantity and quality of light that one plant would be enough already. But then I'm not surprised they are doing so well. Moderation and balance is key to achieve genetically max potential. It's a bio-chemical factory that runs smoother and more efficient when you don't push it and bother it with unnecessary ingredients. Red light is factually easiest for the plant to use, just needs enough of the rest. White is handy because we don't know how much exactly of non-red we need, but it's really not like all pro horticulture led manufacturers are wrong with monos. And whether they are 1, 3 or 5 watt is really irrelevant unlike someone suggested earlier.
It's a bit of perpetual grow with the panama and hindu kush already being in flower for a couple of weeks when I switched to led. And the pck cross is a low yielder but she's very fast. If I would add it all up by the time the panama x silver haze is done I would certainly get a higher gpw than with hps already. Including the ramp up (not using ramp down atm) I only use a little over 300 watt.
Panama itself, one of 8-9 collettes, should be done in a little over a week. Not as great as under hps but then it's in soil instead of perlite and mostly water only.
pck x sh, on soil too.

Once you got all bases covered, which is the case with white, it's an easier choice if you can combine improving efficiency at the light source and the target by improving the spectrum with monos. Even easier decision if you want more light too. There should really be no debate about red being the best photosynthesis booster. Can't go wrong adding red if they are roughly as or more efficient than you run the cobs.
It's ok, not like they hermied. The pollinated buds are from me pollinating several plants, but with a led above it with 4 fans sucking air upwards I should have been more careful... Just a few that won't reach their full potential and probably won't look pretty at the end. Got most in 2liter perlite bottles, which works great but those nearly 4 days hps 600w instead of 330w led were too big of a switch to keep up, clearly stalled a few, probably sucked the roots dry. Definitely going to use an arduino +solenoid for auto watering...

What is the Blue going to influence?
Is it for the extra resin production?
I am running 370 or so watts in my 2x4 spread out over 12 cobs right now.
My Killawatt burned out so exact driw is unknown, as I dim (2) hlg-240s to keep temps down
I like the effects of most hazes, but dont care for the taste much.
Not sure what the Sannies Jack tastes like, but not tasty to me, more chemical, ugly smell like dried hay, grass, spices, and menthol is very faint.
Smelled fruity first weeks into flower, so I dont know what happened.
This and SSH are my main experience with hazes besides C99.
The SSH smells and tastes bad to me as well, but the high is nice till the end when I run out of energy and drive.
Not sure if all good hazes taste/smell like this...
Im way down on grow area from past, but would love a perpetual grow.
I like to have different strains, and get bored easily I think, or maybe I just love seeing them flower and the smells.
What temp are the cobs? They look very dark when not illuminated, maybe 3000K?

Nah, that's just something some people made up for several selfish reasons. What it does amongst others is influence auxin production, which keeps them more compact during veg but also fucks with ethylene production during flower. There's a lot more to blue for veg and red for flowering. FR however does not combine well with blue in terms of compactness, especially when there's also green (similar shade avoidance response as FR, i.o.w stretch) but frankly, I don't mind some stretch. If I add blue it's mostly to keep the blue to red ratio from going to low (whatever that is). The more red you add, the more sense it starts to make to add some blue too. Eventually I want the center module and more blue monos on the same driver so I can run higher blue during veg, by dimming the cobs (which are 2700k) and red monos. Currently my light is more for the 9-12 weeks flowering than the couple of weeks I veg in the 4x4 space.
SSH is one of the best haze hybrids and sparked a lot of others, but it produces several phenos. It has a very similar parentage as Jack Herer (and thus sannie's jack). Skunk NL and haze. Many can be traced back to just a few haze plants Nevil grew out from Sam the Skunkman's seeds. Chemical and spices fit well but grass and hay are not something I associate with haze. Can quick dry a fresh bud and will still smell and taste great. Unlike indicas that smell like grass or hay if not dried properly and gets better after a cure. Most are either spicy, incense or perfumed (smells like actually sprayed with perfume). Love it, amnesia haze is very similar to some ssh phenos, but yeah, love it above all for the effect I associated it with. I can totally understand it smells "bad" if you're not used to it.
Sounds like a lot of cob watts for 2x4. That's what I currently use (not recommend) on 4x4 including driver losses. 370watts hps would be a great match for 2x4, like a gavita 750 in 4x4. With 370w cobs on 2x4 I wouldn't add monos. Well, I guess if you really wanted to upgrade you could run the cobs softer and then add monos and still get both a better spectrum and more efficiency (and reduce total draw, cause 250w, maybe with boost option to 300w, should be plenty for that space).

I have some (3) Retro LED 5500K Cree street lights I use for the beginning of veg and sometimes whole veg. I got them so damn cheap is stupid!!
\
Each has its own HLG-120-24 driver, but they share a single driver usually unless they are tall and flower tent is behind schedule.
I run so much in that small place because thats the only spot for flowering I have and need to maximize yield.
On my best run in 2'x4' I pulled 16.85oz from 4 plants @376W at the plug.
My best GPW ever.
Like 32W/cob roughly.
Last grow was screwed in like every way, bugs, heat neglect from me being stuck in bed you name it. Yielded only 9oz from 6 plants (too crowded also) different strains also.
I mix my Jack with other strains to smoke because it just takes like ash otherwise, like ZERO flavor.
The other pheno from SJ doesnt even want to light like flame retardant.
Ill never grow that strain again. I have 5 pack of fems left too.
I have no other fems and no room for reg sexing, and my orders from Female seeds.NL (3 orders) never came.
I might have to buy clones again, and I dont want to do that because I got bugs last time.
I have clones right now and am hoping for the best.
When I say clones I mean from the clubs, because I cant take my own here.
The seeds that never came were Sex Bud, C99, and Red Purps.
I dont think they will ever come, maybe they are a fake site?!?
