It is still better to log in several times a day because there are a lot of Coin, XP and
resources that may be obtained. If you log in only when your crops are ready then
you will be missing out on these chances. There are many advantages to using up
the Power that is available, not just during planting and harvesting. When you log
at least thrice or four times a day then you will also be able to feed animals that
complete their cycle and tend to the trees that are rapidly growing.
