Hey guys, I use a lot of pre-filled vape carts from a few different companies (such as Bhang and Absolute xtracts) I've noticed that some carts are almost full, while others are just barely over half filled. This is the same strain/same company. For example, one week a cart of Sour Diesel was near full, just a small line was visible from the top. The next week, and it's literally just a hair above half. Any insight would be great, this has been bugging me for some time. Thanks!
Here is a pic for an example, this is how it looked when I got it - no hits taken. Same strain from same place a couple weeks earlier was completely full.
