Sorry, I have no experience with Reverse.

I do have a strain that I crossed (Inca Spirit x Potent Purple) and has a weird hermie trait.
About one out of 6 of 'em throw-out a couple of nanners just after transplanting them to their final pot, about a week into 12/12. A few days later, the nanners start to dry-up (unopened) and I never see them again. At first I thought I was stressing 'em, but it's almost religiously 1 in 6, and I'm fairly consistent in how I treat my plants.
Have never seen a seed from this action, and it always happens at the same transplant point. Doesn't happen at all if I transplant in veg before switching to 12/12.

So to answer your question 4...I have seen plants 'grow-out' of it's hermyism, and finish nicely. Not what I'd call a common occurance, as it only happens to this one cross, but I know it happens.

I'd keep it, but I have a couple of 48" x 18" x 3/8" pieces of clear plexiglass I use to make a wind shield. I put my male (or forced hermie) in the corner, protected from the fans by the plexiglass. Works pretty good and the plexiglass gets a static charge from the breeze, making virtually all dust (and pollen) stick to it.

p.s. If you keep it, watch for bright yellow blotches inside the buds. Sometimes nanners like to hide in there, too.
