I would try looking for some sort of shisha flavoring that you can dip your nugs in.
I would, but I heard either they don't work, are gross, or are expensive. I hope that I can get results that taste better with simple things and a simple procedure.

Bannana, huh? That sounds like it'd smell/taste pretty good. I assume it's ok to put weed in a freezer, although I'm not quite positive. What you could try is putting in the fruit drawer [it's the one that will usually have some kind of ventelation system] in your fridge, so you don't completly freeze your weed. As far as I know putting it in your fridge is fine. About the freezer, hopfully a more experienced member will fill you in on that, as I have no clue whether that's ok or not.
As for the freezer, I think it's alright to keep it in there. I know that certain people preserve their weed in the freezer specifically to keep it fresh. I'm keeping the banana peel in a aluminum foil wrap with holes in it inside the jar which is sealed. This seems to be working so far, it smells FANTASTIC.

Does anyone have any info on whether or not this affects the taste?
