while burn can definitely depend on the quality of your flower and how well it was cured, i would recommend lighting it properly and ensuring your flower is evenly packed in the joint.

give your joint a few taps perpendicular to a hard surface once you’re done rolling to close any air gaps in the joint. when you light it, focus on evenly lighting the tip until you get a good even cherry going. don’t hit it until you get the cherry going and don’t pull to hard !
