Transplanting after flower?

Just curious if you can transplant after flowering has started? And is there a way to transplant without causing any shock at all?

Yes, you can. If you do it early enough into flower, within the first 2 or 3 weeks maybe. Anytime after that, I would this you run the risk of over stress and maybe Hermie. But who doesn't want bigger shoes when their feet are growing? I think a transplant is always good when its needed. My 2¢.
