If using hemp for feed, does it matter if it doesn't all split? would the fish still be attracted to un split hemp?, My guess is they would, so why worry. I recently got some prepared from Angling Direct, 5kg of own brand "Advanta" , with the discount worked out just over £10 delivered. Decathlon also have jars/tins of prepared hemp and other particles at a fair price, worth stoscking up for a on the spur trip. I suppose if you're getting through gallons of the stuff then buying unprepared in bulk is a no brainer.
