I grew them in bins for the first time. I wasn't impressed with the first bin........marbles! We left the second bin another month and got 8 small spuds from 5 tubers. I put it down to bad watering though, these bins were pretty deep and getting the water level right is awful.
Wont use them (bins or Epicure) again, we found they tasted ok. But not as nice as Kestrel.
