Light Temperature Advise

[Gjohnstone]

Looking to build a DIY COB setup, if the lights are full spectrum what light temperature should I go for? Most I see are 3000 or 3500k. Any input would be great

Welcome G.
I run both 3k and 4k Vero's and F-strips on my fixtures. For a full cycle fixture, I would try for 3500K, you will get a slight efficacy bump over the 3000k. Both are great choices so use what's available.

I have 4 55w cobs that are 3500k. They are the only lights I use. From seedling to harvest. I haven't had any problems with them, so I would have to agree with gbauto

Thanks for the info!! I am running a 3x4 with four plants that I scrog. Do you think I would be okay with 4 55w COBS or do I need more?

One per plant has always worked for me
