Bubbleman's rule for assessing dry sift quality under a microscope. Pure trichome heads are round and clustered — they look like grapes. Plant debris and contaminants are irregular and elongated — they look like worms. Keep the grapes, get rid of the worms. If your dry sift is full of worms it needs further refinement through finer screens.
// From the Episode
Bubbleman demonstrated this concept as the simplest quality control test anyone can do at home. Put your dry sift under a jeweller's loupe or USB microscope and look at the shapes. Round, golden, glistening heads clustered together like grapes on a vine — that's what you want. Long, stringy, irregular shapes mixed in — those are plant material contaminants, the worms. The goal of every refinement pass through finer screens is to increase the grape-to-worm ratio until you're left with nothing but pure trichome heads — full melt quality.
