My friend, I set mine up like this...
One tent is auto flowers. Two strains.
Another tent is photo period. Three strains in there.
For my goals and grows this set up works for me. I am able to record all my progress while maximizing my grow space for both photo an auto grow experience.
Some contests on this site only allow enteries with single strains per diary...so if that matters to you then you may want to adjust accordingly. Have a look at mine and you'll see what I was referring to for my goals and grows.
Cheers
