I never have tried nuking the weed......mostly because I read somewhere that it destroys the trichomes but I can't tell you if the statement is true.......just that I read it somewhere so never did it.

The oil I nuke for about a minute to get it to liquid state so I can add the powder.....that's the only nuking that occurs.

You can get coconut oil at your local health food store (unless you live way in the sticks) or even online. I get mine from Amazon.com.

Good luck....and thanks for the tincture tips.
