As far as growing crops go, the most cost-efficient way to get energy and XP for your bunnies is to grow carrots repeatedly. It is not the must fun method, as it requires the most attention.
There is no good alternative for bunny XP, but a good financial alternative for energy is strawberries, and for time, green pepper, radish, or green lettuce.
Surprisingly, carrots are not the most efficient experience for level XP. They, at most, can provide 2 XP per minute while green leaf lettuce provide 4 XP per minute. Thus, green leaf lettuce is the best crop for level XP for time, while carrots are slightly better for money.
If you want to buy your bunnies energy rather than grow it, carrots are by far the least expensive option, but also require much manual clicking and dragging. Green peppers and strawberries are acceptable alternatives.
