That's a great place to start! I just finished a Dinafem Blue Kush, I'm smoking it right now, lol. Good genetics. I have an album for it, if you're interested. With the yield of the Critical and the sativa from the Jack I'm sure you've got a good one. I did 5 Zs under not a lot of light, scrog. Tell us a little about the castle. How far into bloom? Good Luck on your grow! Smoke em if you got em.
