I usually get 6 oz per black jack and there were 4. Had 2 blueberries as well. Like I said, 1/4 lb dried already(not in pic).
They were hanged upsidedown with wire hangers, buds still on the branches for 3 days @ 55% RH. After 72 hours, I pick the buds off and they go in large Rubbermaid snap tight containers , 3/4 full with hygrometer inside. I wait 24 hours and if reading is higher than 75%, I spread the buds out on screens for 12 hours. If reading is around 70%, 6 hrs., etc...
I find that once I get around 62%, its time to put them in mason jars.
You can also suck the air out of the jar with a food saver if you wish for a longer shelf life.
