I used three bags through the season and it was great. I had the odd seed not germinate so well (second year florence fennel, old chard), but I put that down to seeds not compost.
Pretty much everything germinated really, really well. Leeks, onions, shallots, beetroot, lettuce, kale, endive, chicory, dwarf bean, runner bean, climbing bean, autumn cabbage, spring cabbage, radish, turnip, spinach, pea.
