Early germination to increase yeild

Second year growing here.
If I germinate now [12/14] with feminized seed I would think I will have many more months of grow time plant size & therefore yield for a fall harvest as opposed to waiting for spring to germintate. Am I not considering something?

I’m no expert by any means but I just tested that with my last grow and yes my bigger plants gave me a bigger crop also my grow was indoors and I used no training just removed or tucked leaves that blocked bud sites , at the end I think I had the same amount of nice good big buds that got a lot of light and I had a lot more smaller buds that where lower but all and all my yield was more
