The secret to putting a lemon or orange peel in your meds is simple. Do not leave it in there for days without "burbing". If you leave it over night make sure you open the container for 10 minutes or so before resealing it. After a couple of days remove the peel and reseal your meds. Do not let it stay unattended or it will mold.

I have used this method for years, in fact if I have a really nice strain and do not want to change the flavor or smell with a slice of orange or lemon peel I will just pluck off a fan leaf from one of my plants and place it in the mason jar. The bud will absorb the moisture from the leaf and become less dry. It will not change flavor or smell.

A piece of lettuce will do the same thing without changing taste or smell too much.
