This accelerates the growth of a plant by 1000 times normal. This gives 16 2/3 hours worth of regular growth per minute. This becomes roughly 17.1 years worth of growth if the spell is allowed to run it's course.

The plant requires no nutrition for the duration, in order to prevent it from using up all it's resources and dying as a result. However, most plants will not grow past what local resources will allow. Weeds are often the exception.
