So, I'm new to all of this, and in the last 48 hours, I got this http://i.imgur.com/pZcVD.jpg More on the way as well. Anyway, my question is about that Pax there, in particular. Is it ok to just pack that oven good and tight with some well ground bud, and leave it there, and just break it out, vape it here and there, turn it off. Break it out again the next day, take a couple hits, etc? Basically I'm just makin sure that I can use this as a, "Hey I wanna get buzzed but don't wanna bother grindin some fresh bud and packin a bowl, breakin out everything, and taking 3 hits and then packing it all away".
