yeah i dont care for a golf ball head. personally, it looks better if the kok is smaller imo. i think growth rate varies on the tank size and water quality.
What is the average growth rate of a flower and at what size do they develop a KOK?
yeah the ones with the outrageous kok looks nasty to me. if its bulging out like the one in your avatar, i don't mind that. anything bigger is just disgusting to me lol.
