Flushing isnt that important, in my one grow video (sponsered by hesi) they dont flush once!

Well if the stems snap its too dry, maby your drying method sucks.

You should dry it in a cool, dark room, no direct airflow on the buds. Or use this method:

"For curing i am going to hang buds in a cool dark room for 24 - 48 hours, or until the surface of buds are dry, then place them in a sealed bag for about 8 hours or until they feel damp again, this will redistribute the moisture from the centre of the bud outward, then i will repeat the cycle again and again, but shortening the duration of each phase slightly as the buds will begin to dry and sweat quicker and quicker, in three or four days buds should be ready for consumption or storage."

*that was entirly plagerised from the High Times - Ready ,Set, Grow! video
