If you wanna rocket to level 5 just grow turnip. Coz it gives the best experience points per hour
[(3+20+3)/10] = 2.6
the point is using weak fertilizer to reduce the growth time to 5 hours.
then u get 5.2/hour and from 6 plots you get 31.2/hour.
so for a single day you get 31.2x24 = 748
But change this strategy when you go to level 5 to and focus on the fruits to get best cash per hour.
Hope that helps.
