Another way you could do it, adjust the 100K pot until it the output is at 700mA and leave it at that position. Then add a switch anywhere on the dimming circuit. When the switch is closed you will get 700mA and when the switch is open you will get maximum current, ~1450mA.

Very nice I'm doing a critical hog at the moment its 1 of the strongest strains I ever smoked really enjoyed it. I wanted to try the sour jack Aswell but it was discontinued when I tried to buy it. How long will you let the hog flower for??

Ya I was bummed that G13 discontinued the Sour Jack and I loved their Durban Poison as well but lost the cutting and it is discontinued.
The HOG pictured is at ~6 weeks, it looks like it will be finished at 7-7.5 weeks in these cool temps but at ~80F it finishes ~8.5 weeks. This one has a strong skunk / meat / red wine smell, popular smoke and cooperative plant.

Do you count from the day you flip to 12/12 or do you wait a week. Reason I ask is cause I never count the 1st week. I usually let the hog go for 10 weeks including the 1st week that I don't count my temps are 80f

Sorry to keep on but I haven't seen any1 do the hog b4, if u harvest at 7/7.5 weeks do u get the maximum potential (yield/potency). Would u mind if I showed u my hog tonight it's at the last day of week 3 so 21 days just so u could give me your opinion

For sure man post it up.
When I harvest it I make sure the pistils are all dead and the plant has stopped drinking as much. Then I let it get at least 12 hours of darkness before the chop. I will def post up some macros before the harvest so we can analyze/compare.
I have noticed that some of the bigger yielders are more prone to foxtailing and high bud temps can exacerbate that in some cases, making for a very slow finish. Luckily this lady is not prone to that but it is not a huge yielder either.
Here is the same cut at 54 days, when it was cold last February so low canopy temps for this one also 75-78F

Hello Sir,
im since some days new member of this forum, i wanted to say BIG THANKS to you(SupraSPL) and to REALSTYLES.
I did build my own LED light in the optic from REALSTYLES DIY CXB3590 TUTORIAL and with that config from u SupraSPL
@64%
(8 ) CXB3590 3500K CD @ 700mA (23W ea) $380
(1) HLG-185H-C700 $65
184 dissipation W ->66W heat ->
passive cooled heatsink 7920cm² -> 4.23"X44" $68 (could split these into 2 or 4 units)
The light work since one week without any problems
and the best thing is my new light is always so cool it never got hot :O
Again big thanks guys, u both made it able that i could build my own light without any knowledge about LEDS or even ELECTRIC
Sorry for my bad english, but it isnt my 1st language

@SupraSPL 
Hello Sir,
i noticed that u have a lot of knowledge about Led, my knowledge is really bad:/ in compare to urs.
i would like to show ur some datas about a W-peak Horticulture LED(COB), it would be nice if u can tell me if it is worth to buy some of this COBS in future.
i hope this informations are enough on the 3 pictures to make an opinon.

Hello, glad you put together such an awesome light man i am sure you will be thrilled with the results.
To compare your lamp versus the Horticulture COB mentioned above:
CXB3590 3500K @ 23W = 2.98 umol/s/W
Horticulture COB @ 26W = 1.82 umol/s/W

Hi mate sorry I didn't post the pic of critical hog last night once I finished working on the lady's I was due my 12 hours of darkness lol. Here it is now anyway on day 22 of flower 
sorry about the pic it's really poor I know I will be taking better pics. Lol my Christmas tree next to my tree. Does it look about right for 22 days???

For a 4'x4' space and for bloom; With two panels of CXB3590, 4 COBs on each panel and alternating
3000K 3500K 3000K 3500K, I was thinking of adding a 3rd panel in-between those two which would have all 2700K COBs.
So the layout would look like this above the 4x4 footprint:
3000K 3500K 3000K 3500K
2700K 2700K 2700K 2700K
3500L 3000K 3500K 3000K
Would it be more effective for me to instead, continue to use only the 3000K and 3500K COBs and have three panels alternating these two temperatures only, or should I consider a different option for temperatures at this time, for bloom? It seems like the 2700K is also an important temp for bloom but maybe the benefit is not so much. I have no idea, I've just been reading as much as I can to get it right as possible.
I should add, the existing panels have lenses, I was thinking of not using lenses in the center panel to let the light spread out from the center. The existing COBs are the higher voltage COBs, the 2700 is only available in the 36V designation of CB and CD I think it is.
Thoughts?

I have read that 2700 has same phosphor content as the 3000k but just more phosphor so only efficiency loss and no real benifit.
Wait for Supra or someone knowledgeable to chime in.

One thing for sure is the different color COBs are obvious. the 5000K for Veg is much brighter than the 3500K and that one is brighter than the 3000K. The 3000K just doesn't seem to have the aggressiveness of the higher temp COBs. I'm guessing the 2700K would appear dimmer but dimmer might be a bad choice of words and they put out the same energy but that's the way the rods & cones in our eyes perceive those wavelength's intensities? No clue.

Can i ask something here ?? really intrigued with Cob's but something is on my mind i see everyone is mixing spectrum's to there Diy units
As a 1215 watt Nanolux growers running 4 of them i am looking to add 3 full spectrum lights in-between them which do you honestly think would be better COB or CMH
I been looking at both spectrums it appears CMH has a more rounded spectrum in the lower end as well in the upper end or am stoned lol ..
Either way could someone please be kind of enough to give me your imput ?
been looking at nano CMH plug and play,, Please note i am not looking for efficiency as i do own a gas Guzzling SUV.. but i want a honest opinion what route should i go as in cost and Overall performance how much would it cost to make same units in cob COB present prices
Nano 315 CMH 323 bucks
Nano 630 CMH 550 bucks
How much to make 315 or 630 full spectrum
