Plucky, 1st off welcome. Rick Simpson oil is a fairly simple but methodical process. Haven't processed oil to date but on my bucket list. There are many sub forums on this site dedicated to oils & such. Can direct you to some peeps but don't know if they'd approve so will let you look around & browse the threads. Secondly you would need to cultivate or wind up paying copious £'s to purchase visa vie expensive!! Only the best, Peace
