I haves two "Fastbuds" Green Crack autoflowering. It has only been a month and a half and both plants are flowering. The plants aren't very big. I pinched the inner leaves off very early in the development of the plants (mistake maybe?). Anyway, how much will it continue to grow? and will I get a decent yield? 
First time growing an auto flowering plant.
