Need help deciding what to grow next.

So I got my order from Herbies and there are 3 strains that I really want to try but since I am doing RDWC it may not be the best idea to grow all three at the same time even though I really want to. First off let me give you a little background. I have a 5x5 Gorilla tent with 2x600 HPS hoods. My RDWC right now only consist of 6 buckets. I was planning on doing 2 of each as a test to see what phenos I want to keep.

So what would you do or do you recommend? Should I only do two of them or go for all 3? The strains are Barneys Farm: Critical Kush, Reserva Privada OG #18, and HSO Blue Dream. I read Blue Dream is very easy to grow and forgiving, so that's good news and should pair easily with any of the others. I read somewhere OG 18 likes minimal nutes, so that is something to take into consideration. I have not found any info on the Critical Kush.

Thanks in advanced for any input.

Perhaps I should have posted this in the strain review section? I thought it was more appropriate here due to my RDWC setup, otherwise I would grow all 3 since I could take care of them personally instead of them all being connected.
