I have to agree with Rick and I also think if you can hit the DLI targets with 12/12 why leave the lights on longer and pay for more electric? That said please keep us informed on how that goes, I eat my words a couple times a day and they dont taste too bad. lol. The Unknown + Spartan Kush is a killer smoke without any cure. 

I have to say there is something pretty cool about seeing seeds you made pop and grow isnt there. I hope more folks get into it. You learn a lot about a strain with repeat grows so if a person can perfect a cross they made it must be a great high. Pun intended
