Can you still make water extracted hash from mildewed buds? I heard somewhere you could...

Will buds mildew even if the humidity in the room is around 50%?

And i was wondering why OG Kush is called "Kush" if it's mostly sativa. Real strains of kush are nearly if not 100% pure indica and share genetics originating from the Kush Mountain range in the far East. Maybe the name comes from similar effects of smoking? Any ideas?

Peace!
