That was my general thought as well, as when I've set up a Growth pattern, I either set it up to where it takes forever for a true change to take place, or I set it up to relatively rapidly happen, only to later disable it after it reaches a certain point. This will allow for not only a way to preserve the use of the Growth function without having to stay in a constant state of pure growth, but also additionally act as an imprecise tracker for the amount of orbs currently held.
