The seeds are not auto they just flower basically under 15 or so hours of light outdoors. I tried 2 different crosses to make sure they worked outdoors for the last 3 or so years. Maybe 10 or so percent will flower like a photo at seasons end. Your cross sounds great. I'm thinking next cross will be mephosto female with dank Sinatra photo male. But seeds are only good for 1 season . the next generation they will be all photo flowerers .Interesting,!!
I am seriously considering, a (Grapey Walter (auto)) x (Deep Purple (photo))
Thought only 1/4 seeds auto. However, I can live with semi auto outside. Flowering at anything under 15 hours light is good by me.
Make.some.seeds this winter for next summers outdoor run.
