Diesel is a sativa dominant hybrid with a 30:70 indica/ sativa ratio. As for the smell, it is quite similar to sugar coated rice crispies and freshly cut fruit. After grounding it up, it smells even more like diesel fuel and grapefruit. After smoking the strain, you will realize it has a grapefruit berry taste to it during the inhale. It can be a bit sour but it is exceptionally smooth at the same time. However, during the exhale it can be quite rough.
