I read this somewhere, and using it seems to work pretty well
"7 sugar, 5 lemon, every 10 degrees = 1 cube
ie if it is 80 degrees have 8 cubes, if its 30 have 3 cubes
make it $0.50 on the first day
increase by 25 cents every 3 days"
Once I was able to, I started advertising, and never stopped, and only kept adding advertising.
