The Blueberry I grew from Zambeza is a great smoke but doesn't seem very potent. Although I've had a few strains that didn't initially trip my trigger, but after they sat in a jar for a year, lit up my world. The Zambeza Blueberry is a Blueberry/Northern Lights cross, just like Nirvana's Blue Mystic. Nirvana claims their Blueberry Kush is for people that want more Blueberry flavor and a more potent strain than their Blue Mystic. Well that was the seller for me. It was exactly what I was looking for. We'll see how it turns out.
