Hi. I just purchased a hot box. First there was no effect, then last night I started using it and saw vapor come out. Hot box says this should not happen. I am leaving the box on because nothing seemed to happen and I thought maybe the temp was too low. I cannot say about VAPE( I am a newbie started on Saturday)but wonder if at first the temp was too low and then today was too hot. I also did't know what the best type of product was. I just inhaled a whole lungfull of GREEN leaves and it hurt and burned like hell. Didn't do that at first.....
