Robust: FECO

What Is FECO? FECO stands for Full Extract Cannabis Oil — and here’s where it gets a little confusing: It’s also made from the whole plant, just like RSO. FECO and RSO are often used interchangeably, but they technically differ in how they’re made. How FECO is Made FECO is made using food-grade ethanol — a safer, cleaner solvent — and it’s often processed with a focus on preserving more plant compounds, including heat-sensitive terpenes.
