"Thanks for this info.
I'm learning how to make dry sift hash using silk screens but there's a lot of conflicting information online (YouTube and Marijuana forums). There videos where dry sift screens are arranged from lowest micron to highest. Like, 70 micron, 110, then 130 at the bottom. In My Opinion, this arrangement only works with bubble bags.
Your article has helped me gain the right direction in terms of screen arrangement. Currently. I reside in Kenya and have access to landrace Ethiopian sativa strains filled with plenty trichomes. "
