Hey whats up DGC fam,
this was a tip from a fellow grower so i cant take credit for it but its a good hack or if you are in a pinch.
I do this during curing, or if the initial drying has gotten too dry, instead of Boveda packs I keep the larger stems of the plant i just harvested and if i need to re-humidify my flower i cut a 2 inch piece of the stem and pop it in the jar. The stems dry slower then the flower and although i wont know the exact rh of the stem, once placed in the jar with a hygrometer i just adjust rh by burping as needed. i like this because I know the source of the water/humidity in the stems, its free and it works.
