So I just started vaping BHO with my pax. I have been putting a little BHO at the bottom of the chamber then filling the rest with cotton. Then I make sure to hold the device upright and all the BHO drips into the cotton. My only question is. The cotton comes out black where the BHO seeps in. The rest of the cotton is white. Is this the BHO or the cotton burning. Should I be worried about the cotton?? Because according to this auto-ignition temperature of cotton is 248 F. I'm vaping at 370. The rest of the cotton seems perfectly white though. http://www.tis-gdv.de/tis_e/ware/fasern/baumwoll/baumwoll.htm#temperatur
Idk bout bho but I tried some avb iso hash in my pax but it didn't really work well. I ended up just using it in my buddha.
It's the BHO, and it's not burning by the way it's just how exhausted concentrates look like. I've had different hashes through cotton and it all looks blackish.
