What is the difference between extracting RSO and FECO?

The main difference between FECO and RSO comes down to the solvent used during the cannabinoid extraction process. FECO is made by extraction with ethanol. RSO is usually made with isopropyl. The reason why isopropyl is used is mostly accessibility and price. We do not recommend the use of isopropyl. The extraction level for both RSO and FECO is roughly the same.
