I was always told not to touch the buds because touching them(or pulling them)
would cause that calyx to not fully develope.
It needs the hair to finish maturing,I think.
Otherwise when you pull the hair I think it willl create a bunch of hollow calyx's.
Keep your grubby fingers off your plants people.

I don't think your ever going to get a real answer.
Just try it on one plant.
Or one branch.
