my herb is very dry and it coughs when i drink it

I'm going to disagree with gottagrowsometime here... I rarely if ever flush my grows and not one of the people who use it has ever complained. The best thing for you to do here is to let it cure a long time... make sure they're not overly dry in the jars (if they ARE really dry, you can put a piece of lettuce in the jar with your buds and that will help rehydrate them to a decent moisture level or you can use a Boveda 62% pack). I think you'll find if they cure for a month or so, the smoke will be much better... Good luck...
