How to make Particles grow faster

I want to make my particles grow really fast with time. I’m using Size Grow in the Particle Animator. Setting Size Grow over 1 speeds up the growth but I’m getting an error when I do:


So I figured I’m not suppose to set Size Grow over 1. Is there another way to speed up the growth of particles without getting an error?
Thank you!

I have often used Size GRow over 1 and never got this error. How much Energy to the have? There is also a field down below saying Max Particle Size, maybe try to boost this up too?
Hope it helps!
