I used to use silicia packets for my weed, but in a different way. I would put my weed, and then some celestrial tea bags, and the packet in a jar and close it tight. The weed would pick up the smell of the celestrial tea bags, for instance rasberry or whatever I used. Worked alright, you could smell the rasberry in the weed when you smoked it, not so much taste though. Good thinkin for drying tho : )
