Dabs Labs HCFSE is a high-cannabinoid variety of THCA diamonds with minimal terpenes added back in. HCFSE/HTFSE stands for high cannabinoid/terpene full spectrum extract. HC often appears in a diamond shape, while HT is saucy. By eliminating unwanted molecules from the cannabis trichome, like waxes, lipids and fats, the final hash product contains beneficial cannabinoids desired most by cannabis connoisseurs.
