i use an orange peel too... or a small sliver of apple... and recently sugar blossoms from my yard that smell like fresh cut strawberries. iv never had it ruin the weed, the trick is in moderation. just like the idea of "natural" moisture then just dropping water in a jar of weed? but if you are worried about the taste and smell you can wet a paper towel, fold it over twice, and secure it to the lid (not mixed in withe weed!)just screww it down with the jar ring. this will perk it back up i just wouldnt leave it on there very long at all.
