Hey guys so some of you might recall a newb LED thread I posted a little while back asking about LED recommendations. It was made very clear to stay away from commercial blurple LED even though some of them looked pretty decent but very highly over priced. Through all the kind feedback and debates from the RIU members it was recommended again and again to go the DIY route and to build my own COB fixture. Now I have been researching about building my own COB and with importing and shipping charges it's going to actually cost me around the same as buying a commercial LED. I have looked at Optic and Heavensbright and I'm also keeping an eye out for PLC, however I'm still contemplating on building my own COB LED. My questions is I've seen most guys using 3000k COBS and some guys using 4000k and some saying a mix of both is good. Then I've also seen some saying that 3500k would be a better mix. What I'd like to know is what would be the best recommendation to use for a full grow for use from veg to flower? I'm leaning towards 3500k although I've seen a lot is successful grows with only 3000k. So for all the COB DIY gurus at RIU what would you suggest or recommend? Thanks once again guys.
