A bioshelter can be used for cold-season food production, limited mostly by how cold it gets at night in winter, and how much growing space is available with full sunlight over the whole day.
If the temperature is maintained above freezing, many garden vegetables, particularly cold-hardy crops that produce greens with edible leaves, and cooking herbs can be grown inside such an environment. These can be planted either in deep soil beds or pots. Larger plants like fig trees and lemon trees can be grown in large containers.
Edible fish can also be produced in aquaculture ponds and integrated with food crops in hydroponic/aquaponic systems.
