Sometimes when you buy stuff there's little bags of silica gel dessicant in the box or bottle or whatever to keep things dry. Keep those. If you get damp weed you can put your open bag in a sealed container with some of those dessicants. I use those new ziplock containers.

Dessicants (dryers) can be reactivated by heating them at low heat in an oven.

With dessicants you don't have to heat the weed to dry it.
