In case, if you feel that you will be gone for some time , like going to school

or bed, then have all the adult Sims plant no matter how long it takes. Make

certain that they all are motivated as they will make 1.5x amount of

Simoleons. Allow the babies to sleep and allow preteens & toddlers to watch

movie marathon.

While you are sleeping, make your Sims do some work like gardening and

stuff. If you garden around seven or eight hours crops during night, you

would wake up with huge number of XO & Simoleons.
