This chapter examines how crops in space farm stages are harvested, examining two harvest methods: big bang harvest (i.e. traditional seasonal harvest) and continuous harvest. Big bang harvest is how field crops are harvested at the end of the growing season on Earth. In the traditional method, crops are harvested, the field is cleared and then replanted. Plants are then grown to maturity months later, and all plants of the same crop are at the same level of maturity. Continuous harvest is where a portion of a crop is harvested each day and replaced by planting every day, as is done for vertical farms and some tropical crops. Both harvest methods are compared using planted area (footprint), for plants and animal crops such as fish. The resultant comparison informs stage size and mass flow, and therefore space farm size.
