hey man for that fixture i used the meanwell APV-12-5. it runs them at 5v. I did some research beforehand and was able to find the amps that those arctic alpines pull at 5v but i'd have to do some digging to find that info again. i do believe i remember that there's some room leftover for more fans but don't quote me on that. sorry for the semi vague answer but thats the driver. good luck
Right around 75mA @ 5V
No.
Nice.
ok got ya what kind of PPFD you looking to achieve? I can maybe help out with some numbers as I have a spreadsheet to calculate PPFD and its surprisingly accurate
(4) Vero 29 per HLG-185H-C1400x ? At what voltage and current?
1 of 10 of my Alpine11 fans spinned significantly slower from the beginning and finally didn't start rotating at all. Not sure if it happened because of the 5V or a faulty part. The aluminium heatsink is now running in passive mode with a V29 at 1050mA. Though it's getting quite hot, I think it will survive until proper maintanance (probably soldering in another fan, probably changing the RS-15-5 for RS-15-12) is possible. However, due to this experience I guess my next fixture won't feature Arctic CPU heatsinks.
I would suggest to not use the arctic passively. Very good chance to fry that poor vero.
1.4A is what the driver puts out.
Thanks, but I'm logging everything with a PAR meter. No offense to any math wiz here, just trying to use real data to achieve my desired results. Under my 600W HPS my largest densest cola's grew under the "hot spot" of the reflector which receives about 1000 PAR @ 22". I would like to achieve this intensity everywhere in my grow to maximize potential yield.

Real data is always the best data. Just thought with the data I could provide it would accelerate your process of data collection by giving you an idea of what you would need to achieve your goal without going through as much trial and error to figure it out. Nothing beats real world data ever
I have a couple of the Chinese cobs in my setup along side the veros. A couple of my 6500k bars with just two of the 50W China cobs are doing great. Low heat and the ladies love them. I mainly use 5000-6500k in veg. I've seen people using 4000k claiming success but all I noticed is painfully slow growth with that spectrum..The "Return to Thunderdome" version... 585 true watts.
will that make my Johnson grow ?
my cxa3070 cobs are 8 inches over my cola's, and the ones close are loving it, its been at that height for 2 weeks and the leaves are not burning, but the cola's closest to the cob measured at 8 inches, are building more bud and frost than the colas that are 10 or 12 inches, bear in mind I am using 2 cobs for this flower, I dont know if you were using cxb3070, but for sure the cxb3570 8 cree panels could not go that close, maybe someone else could chime in, but thats where my cxa's are
Nothing stimulates your plants female parts like a Johnson lmao
@robincnn I like your lights. Do you use them for veg or flower? Do you have a journal I can look at?
