Buds are getting dry, but stems still doesn't break. please help!

Sup guys, I've been hang drying my plant in a well ventilated cardboard box for 6 days now. And her buds feels a little crisp, she even bounce back in formation when I squeeze her a bit. Only problem is the stems won't break nor snap. They just bend. And she starts to smell like
Grass too.
Temps. are usually 77°f and humidity around 55-61%
Can someone tell me what to do?
Much appreciated

great job fellow, your not doing anything wrong and the longer it takes to dry the better the smoke will be.
a bud that size, in that environment could take 2 weeks to dry but it will be worth the wait
