What are the best strains??

I have a little 3X3 closet thing going. I have had fairly decent success using scrap seeds picked up here and there. Getting ready to do some switching around a bit and looking to start over with some good seed strains. Just looking for suggestions on a good strain to grow in limited space like I have. Thanks in advance. Enclosing a pic of something I found...just wondering what strain this might be.

Its all based on preference. Some genetics grow better in indoor settings because they stay short or bushy. Check around on Attitudes site and you'll find something you like. IMO, I really like any blueberry strain thats mostly indica dominant. The cheeses are also wicked wicked dank.
