Stinky Hemp: Prepare a kilo of hemp seed by simmering until the husks split open. Once it is ready drain off all the water and turn the still-hot seed into a bait bucket. Quickly add 24 drops of Black Pepper Essential Oil and 12 drops of N-Butyric acid. Immediately seal the bucket and shake it well so that each seed receives a coating of the two attractors. NB. Hold the lid on tight while you do this! When the hemp has cooled it is ready to be used or stored.
Red Hemp: Prepare a kilo of hemp as above and then add a heaped tablespoonful of Robin Red (or any of the other Robins) to the warm seed.
