Storage of seed potatoes
The recommended storage for seed tubers is diffused light store (DLS). Tubers are placed in chiting trays, racks or shelves in a building or storage where light can pass through transparent plastic sheets or fibreglass walls.
Sprouts from DLS have study sprouts. Sprouts from dark storage have long ad etiolated sprouts that are susceptible to damages during handling.
Vacant rooms or unused buildings can be renovated to serve as a diffused light store.
