Hello, I would like to build an led light but only see the 2700k version available for qb 304. Would I be ok continuing with the 2700k instead of 3000k and what would be the difference. Would I supplement with additional k light during veg and then just 2700k when flowering after stretch? Any input would be appreciated, thanks.
That would be awesome…i was reading some of his stuff and he impressed me, I should have known he was a specialist. Glad I found this website. it already…
Do you want the light to potentially run both veg and flowering cycles with? I would opt to stay away from 2700k if that is the case. I was there this morning and it appeared that 3500k was available, that would be a better choice if you want to use for both. If not, possibly check on the 288 boards in 3000k or 3500k.
Thank you for the input. I think I will go with the 3500k, it’s just that I want the qb304 because more output and better efficiency as you mentioned in hlg 550 post. Thanks a million you are awesome.
That’s highly suspect to drive currents. You can run a 288 board more efficiently than a 304, or a 304 more efficiently than a 288. I’d have to double check, but at same power levels one is like 1-2% more efficient. So I would lean more towards whichever fits the space more efficiently. You can fit three 288 boards on a single constant current driver in series no problem. Can’t do it with a 304 board. Plus the new 324 board gives some spectral advantages. May be worth looking at too.
