I'm reversing Sour Stomper, but making seeds also with this next run. I think I'll be doing that each run.......making seeds and collecting pollen...........from the prior run that impressed me. I got a new little tent just for doing this..I have a goal to reverse the Sour Stomper this go round since I only have one more seed. Same goes for the Fast Buds Lemon Pie, I only bought one seed with the intent of reversing it to make some S1 seeds for my collection.
