Three month cycle? You've been budding for almost three months. I did a 5 month winter/spring grow and you'd be surprised how much of a difference a 4-5 more weeks make.

5-6 weeks of veg growth before flowering is typically the sea of green method but those growers are growing dozens of plants at once, the idea is if you have the resources for dozens of clones you can harvest every four months but you're only getting a small amount per plant.
