I had mine in the box they were delivered in. After a few weeks they were very sprouty!! But I took them out of the bag, put them in an egg carton and put them on top of teh cupboard in teh pantry where it is airy, cool and filtered light. After a couple of weeks, I found that the shoots hadn't gotten longer but they were just fatter. When I planted them I didn't have the impression that the shoots were falling off, they seemed firmly attached. MAybe this is something to try??
