Vero 29 se “b” “c” or “d” which one ? Thinking of building 3 x 3000k 3 x 3500 k and 3 x 4000 k

[petegreenfeet]

so you think 9 cobs in x 6x2 is too much ?
i could always drive the b version at 700mha or 1050 mha and get 50 w / 70 w and much higher efficiency

im really trying to get the one light does all

Hey there

Nah I don't thinks this is too much, in fact the more cobs you have the better light spread you have, so yeah I'd advice you keeping the Cobs at 50/70W , any higher wattage would be overkill with the 9 cobs you're going to display.

Trust me 9*50W is really going to do magic already.

Well I can't tell you about mixing COBS because I would say there is enough blue in the 3000 / 3500 K already but this is only my dime.

If I were to use 4000K I would use only 4000K for veg and then switch to the 3000's and 3500's.

I myself mixed spectrums with 2* 3000K cri 90 and 1* 3500k cri 90 in a 2ft* 4ft and it was really nice, never could give the full juice to the COBS to run at 80W /COB coz the baby was grown under a shitty lamp from the begining and as soon as I switched, she went into beserker growth and ended up beiing in a too small pot but no way to transplant because 1/2 flowering made.

So I would say you should use the D version or C version depending on the driver you're going to use, wether constant voltage or constant current.

I'm more confident with series wiring with cobs so I would give my advice takin' D versions with an HLG320H-C1400 or C versions with HLG320H-C1050 or else you'd have to get another 3rd driver because of the total voltage of your COBs

If you really need more juice since your heatsinks can handle it even if I'm not sure you will need it, you could always go with 5* CObs on the 320H-C1750

Well, it really depends on how much max juice you want your COBS to spit and the total number of Drivers you plan to get, then you have to do the maths with the Drivers input

i was thinking of running 3 drivers anyway and splitting 3 different kelvin on 3 different potentiometers so i can add more red or blue when needed and probably at 1400 on the b s and 1050 on the c s

nice one thanku, this is my first build aswell so im really looking forward to it
