Draw Resistance – This term refers to how hard you have to inhale from the mouthpiece of the vaporizer. A low draw resistance means that you do not have to expend much more effort than breathing in. A high draw resistance means that you have to use more force when inhaling and you’ll have to inhale stronger. Low darw resistance is desirable, and it means a more comfortable inhale. Here are 7 tips to help you reduce draw resistance and get more vapor.
Session – Using an oven full of herb is a session. So, if you vape the contents of an oven, that counts as one session. If you refill the oven and vape again, then that is a second session, and so on. You can continue your sessions until the battery of the vaporizer gives out, which is why batteries are sometimes measured by the number of sessions they can produce before dying. As stated in the FAQ, on-demand vaporizers allow you to have multiple sessions with just a single oven. For more info read our detailed post about session vs on-demand vaporizers.
