Colouring tobacco involves the breaking down of chlorophyll & starch. If the time given to break down chlorophyll is too short you fix green. Ethylene speeds up the enzyme process of breaking down chlorophyll. Ethylene generators are beneficial in colouring a) lower leaf, b) droughty tobacco, c) tobacco with green shoulders, d) over fertilized tobacco. Our generators use bulk dispensers, are cost-effective, can be adjusted to suit your tobacco style and ultimately increase output.
