It takes a very long time for me to finish my trench, around a half hour, and I need to use 2 batteries to finish it off. My trench never turns brown either it's always green when I finish, I just stop when I don't taste anything anymore. Is there something wrong with the batteries?
ok if you follow these steps then theres something wrong 1 . make sure your batts are completely charge 2. hold the batt in, take sips for excess of 15 seconds remove battery shake box and repeat until the trench is shot and yes most weed wen donzo taste liek burn something some say burnt popcorn id say its around there if your doing this and your not killing a trench in less then 5 minutes u might have a problem
Hard to say, sounds like it isn't getting hot enough, but it could be a lot of things. How are you hitting it? Drawing quickly or slowly, long or short? Are the batteries fully charged? When you push the battery in do you see the light behind the trench?
Make sure the metal that contacts the battery is nice and shiny. Also put in some really finely ground up bud and hit it several times without shaking, then gently tip the box sideways and tap gently to flip the block of weed over and examine the color change. It should be an even color along the length of the trench. If it is darker toward one end then the lighter side of the screen has been damaged or is not heating well.
