"Snow Caps" refer to high-potency cannabis flower coated or dusted in pure crystalline THC or THCa isolate, giving the buds a snow-covered appearance. 
 
Effects and Characteristics of Snow Caps
Appearance: Extremely frosty or white-dusted exterior due to the heavy layer of refined crystalline isolate rolled onto the outside of the bud. 
Potency: Exceptionally high THC levels, often pushing well past standard top-shelf flowers because of the concentrate coating. 
Experience: Heavy initial cerebral rush blending into a profound full-body melt; best suited for experienced consumers rather than beginners.
