Well with tissue expanders you know we have some theoretical possibility but probably cheaper and quicker to just buy yourself a cape ;D but Clayton man you kill me.Someone told me that if I stretched my ballsack for an hour a night, eventually I could wear it like a cape. Is that true? Sure, I expect ya'll to say hell no, but maybe someone is actually aware of why it's true or false. Don't say size depends on stretching skills, this is another conversation.
As for the question he asked yield and potency are dependent upon the grower's skill, the environment experienced and the genetics. So there ya go.
