No plant types need to be take care of more than once a day.
When planting, oversoil/overwater to the max. Plants hate it, so they grow sick. But for any type, once they drain a little, they fully recover. Then toward end of 24-hour period they run short on nutrients, so they start getting sick again. But not a lot. When harvest time comes, they are still giving 100% for at least 5-6 hours after harvest time; so you have little freedom.
Now, this only works with good IS pots (I am all Zeus, but there are others) and with best soil/water. But at 85 you should not be using anything else anyway.

Oh, and people who have more than 3 classes are clinically insane.
