I got some weed yesterday that was extremely dry. I packed a bowl into my vapor genie. I checked the bowl after a couple tokes because it started tasting burnt,and sure enough it was nearly half black already. Anyhow I have read around the forums that some people like to dry their weed out before vaping. Of course this experience would make me wonder why they would do that. Anyhow I know I will be especially careful from now on not to buy extremely dry weed. Weed that looks a bit dry can be not too bad of a deal,since it will be less dense and so at least l get more for my buck . However there is a point at which the weed is so dry like this stuff I had that ,you would have to get about four times as much of good fresh weed if you are only getting one clean hit per bowl.
