Yes could probably benefit from some extra red, I am thinking of mixing the 4000K 70 CRi with 3000K or 3500K and maybe they will complement each other.

Do you really think it will be enough red...cause I was planning to try 4x4000ºk alone first in the 3.5*3.5 next time...and 8 x cxb 3590 3500ºk in the 4*4 then maybe add 4 3500ºk 36V @700mA in the 3.5*3.5...next step more cob less mA more efficiency less electricity more gpw less grow more time less work!!!!
Have a great day ★

...good co2 sensors modules for arduino or similar are expensives...
...from my inexpert pov... ...maybe...
http://www.projectems.it/monitoraggio-ambientale-monitoraggio-co2-arduino/
http://www.veetech.org.uk/Prototype_CO2_Monitor.htm
...or maybe a co2 meter with data logger for good monitoring on manual way...similar to... are expensives too.. but i saw it on ebay or similar more economics($80-120)...
...links and pics.. are only for examples or ideas...
...i know Wilson... desactived ....thanks Supra...
...and sorry for my offtopic post...
Saludos

I got a mq135 sensor from a friend.
(the mq811 should be better)
Already added to the breadboard
and calibrated agains 398 ppm.
The arduino also controls the power(start/shutdown) of my Leds and flooding timmer with a relayboard.
Im looking for an effective 730nm cob that i can add to the arduino setup to send the plant faster to sleep.
hard to find one.

use 730nm monos see stevesleds or rapid led they both have them

Another question to add to the heap: Has anyone been recording any data from their light sets, DIY and/or commercial? I've been away from RIU for a few months and was curious to see any data comparisons, specifically between Vero 29 version 2 and CXB 3590 cobs had been executed and performed.

Hello @AquariusPanta
I did a test here. Supra also has his test on page one for cxb only. You have a par meter too. Please share in that thread if you have any similar data of vero VS cxb

Thank you, Robincnn, I have a few data sheets posted on the resource page for heavenbright.com for anyone who is interested. I'll see about uploading those onto here for anyone who is interested as well.

Here's a link to the live spreadsheet that you can work with and download for yourself

Hello, apologize if it's already been answered, what do these numbers mean exactly?

I can only answer what I know and the 325 represents what a cob would need to put out in Lm/W to be 100% efficient,I assume the same is true for the 4.66u moles

On the spreadsheet those numbers are slightly different for different cobs.

Yeah I noticed that, and was wondering about that

gah, without following Supra's spreadsheet trying to figure out the most efficient LED available hurts my head.

325 - LER - tells us how many lumens each radiometric watt of light produces
4.66 - QER - tell us how many photons each radiometric joule of light produces (in the 400-700nm range in this case)
These are qualities of a spectrum so they should be slightly different for each one.

one more quick question (which im pretty sure has been answered in here but thread is getting long)
where 3.9 is listed as acceptable number of cobs what is the effect of running 4 (at constant current). does it starve them for voltage or for current? (or im guessing it moves both along a constant curve of V/I for that particular COB)

Yep 3.9 might be a deal breaker. For example, if the HLG-185H-C1400 can only put out 900-1000mA for 4 Vero29s in series, it is putting out less current than the HLG-185H-C1050 would AND the HLG-185H-C1050 can run 5 Vero29s.
One solution could be to use the HLG-185H-36A and run the 4 Veros in parallel. That way you will get about 1.38A to each Vero29 and the current can't runaway on you because you can set the max voltage screw at 37.5V, which would effectively limit the current to about 1.75A for a Vero29.
