What temp COBs for flowering

Hello,
I have at the moment: 2 x 3000 & 2 x 3500k cxbs.
I'm considering adding 2 more, this lamp will be used for vegging aswell as flowering, I assume it would be best to add 1 x 4000k & 1 x 5000k?

Any thoughts or suggetions ?

thanks, UKP

3500 is great for all around veg and flower. 5000k will make your flower times longer.

3500 seems to be the consensus. I am running the back corner with 3 k (4) 3590's. I may see a difference. It seems when I ran the 3k veros the buds were a bit better. Takes 3 months to see.

i use both..one side of room 3000k the other side 3500k...i can verify they both veg well..the 3500 k seems a little more better for veg with what i am seeing but both have don fine and the r both rocking it in flower

Thanks, 3500K it is,

3000k and 3500k work fine for veg either way so it's not like it will matter.

I have an assembly line going of 4k 3.5K and 3k.....starting with 4....I still get lots of variability after months of this....So spectrum wise, there is lots of work to be done to come to any type of conclusion of what works best or better...... they all do in some ways.....imho
