So the other day i bough a dab rig with a tree perc inside, and the first thing i noticed was that it was almost impossible to pull any air through at all. Then i figured it was the water levels so i tried every different combination and it still wouldnt work. Then i noticed that in the tree perc, only one of the stems works and it is filled with gunk, but all the other stems are clean and wont pull air through. Im pissed off because all i want to do is pull air through like a nornal bong but it seems to me i was sold cheap chinese glass... smh...
Have you cleaned it out first? Most crappy percs get the passages blocked when they are blown, the airways close up and you end up with not great airflow.
