This is some heat right here. You can see the Z mixed with the RS just by looking at the nugs. The tree gives you a nice sweet sherb scent from the RS with a nice zesty lemony type scent from the Z. The taste on this is very similar to the smell. The cross on this strain gives you some very good effects: heavy/lowered eyes, relaxed body, cerebral high with a positive mind, and you get a nice light headband feel above your eyebrows. This shit will have you kicking back. Clean ash and thick smoke, get your hands on this shit if you can. Hopefully this releases on a more mass scale.
