@Num1bigguy thats an awesome plant. I was just going to ask you if you grew the pounder and different than the white widow?
There are guys growing white widow all over the ILGM forum and the only thing I've ever read about popcorn buds were from some of the sidebuds being a little popcorny (?) and that was most likely the result of light penetration, I'm guessing.
I'm a bit of an analytical person so when I see something like your talking about I can't help but want to look at all aspects to see what could have been the cause and yes genetics are one possibility.Especially when I see the picture of your monster plant lol
