I don't know how much help I'll be since I haven't managed to make any rosin, cco or even hash yet myself but I will try.
Basically, there are 2 types of cannabis oil extractions:
- Solvent
- Solventless
Butane Hash Oil (BHO), Live Resin (essentially BHO but made with fresh bud), Tinctures, Rick Simpson Oil (RSO) and Concentrated Cannabis Oil (CCO) are all extracted using a solvent, e.g. carbon dioxide, butane, or ethanol.
My preferred extraction type is solventless and my method is to infuse some warmed oil, e.g. olive, sunflower, coconut with decarbed cannabis in a mini-crockpot for about 3 hours, stirring every half hour or so to make it.
I think distillate and CO₂ are also both solventless.
There's also honey oil, which I think is a purer hash oil but I'm just guessing as I've never researched it and trying to now has become difficult as the Pineapple Express oil I took 45 minutes ago has kicked in.
