Very true, even my biggest colas I chop up into actually big sizes because mold is easy to set into those bigger bugs while dryingshits easy, but whats not easy.....is being able to supply every needed resource to that size demand.
its quality, not quantity.
when you dry that giant bud you'll likely trim all of the buds off of the middle thumb size stick, making ping pong size buds after all.
Genetics is 90% if not more. I had 4 outdoor plants 4 different strains, all fed the same, pretty much exact same conditions, and only one produced football size colas.
The smoke was ok but the ones that produced the smaller colas were way danker.
Pure power plants (ppp), big bud, and new York city diesel are a couple of big bud producers to name a few.
But just like human women, bigger isn't always better.
