Choose the largest Boveda that fits in your container. You can never use “too much” Boveda.
Use more Boveda than the minimum recommended. Think about upping the number of Boveda you use in your container if it’s in an extreme climate (desert-dry or rainforest-like) or when it’s exposed to seasonal humidity swings
Close your container once you remove your herbal medicine. The more you expose Boveda to air, the harder it has to work and the shorter it lasts.
