Please be aware that making CO/RSO can be very dangerous if you are not careful. The solvent used for extraction in highly flammable. Please take extra care!
Also, treat this medicine with respect. This is seriously potent and if not dosed correctly, it will put you flat on your back. Ingesting this half the size of a grain of rice will knock you sideways and the high is intense!! You’ve been warned! lol
Before you start, it's good practise for a 4 week cure. Do not decarb your buds straight from the jar. You need to dry them out more. Set your oven to it's lowest temp. Mine is between 80 & 90 C. 15-20 mins at that temp should be enough to dry them. They will feel crumbly when done. Or, leave them out for 24 hrs in low humidity but i find the oven easier
Equipment
1x nonstick, PTFE & PFOA “free” frying pan. These do not have any nasty chemicals leach out when used
Deep wok
Muslin bags / cheesecloth
Roasting bag
Silicone spatular
Isopropyl Alcohol 99.9% food grade
Unbleached coffee filters
Roasting bag
Funnel
Oven thermometer
Electric hob
Grinder
Two curing jars
So, for this test run i’m using 28 grams / 1 Oz. My buds has been curing for around 5-6 weeks now but 4 weeks is golden
1. Break the bud up into small pieces and place inside a roasting bag and tie closed
2. Heat your oven to 110c -115C using your independent oven thermometer. Do not go by your ovens!
3. Place the roasting bag in the oven on a baking tray for 60 mins
4. After 60 mins, remove from the oven and alow to cool
5. Grind the cannabis
6. Now place the cannabis (in the roasting bag), bowls, funnel, fork and solvent in the freezer, on it lowest setting for 24hrs!
7. After 24hrs, remove from freezer, place the cannabis into a bowl and pour over enough solvent to cover the contents. Do this as quickly as possible
8. Gently mix around in the solvent for around 30 seconds then leave to sit. Total time 3 mins
9. Pour into your muslin bag and strain the liquid out by squeezing the bag
10. Empty the buds back into the bowl and repeat a further 2x. So 3 washes in total
11. Strain the liquid through your unbleached coffee filters. This can take quite some time and half way through, i use a new filter to speed things up a little. If possible, allow to strain in the fridge or freezer. We want to keep this all as cold as possible!
12. Once strained, place back in the freezer for 24 hrs
13. Add boiling water to the wok and place the frying pan on top to heat through.
14. Add your solvent to the pan and after a short time, it will start to fizz
The idea of the wok with boiling water is you turn the heat off before you add the solvent to the frying pan as its highly flammable! Let the heat from the water boil off the solvent. Make you have windows open and having a fan to blow away the fumes is a great idea!
You’ll have to remove the frying pan at some point and re-heat the water in the wok, then continue to boil off the solvent. The solvent will gradually evaporate and you’ll be left with thick resin/oil.
Once the solvent had gone you’ll notice small co2 bubbles in the oil. If you want highest THC content then once all the solvent has gone, your finished.
If you would like a more sedative oil, then continue to heat until all the small bubbles have gone. This will give you more CBN.
Freezing the flowers and the solvent is called winterisation. This helps clean the fats, wax and lipids from the flowers. It also helps keep down the chlorophyll
Im sure there are other ways to do this but, this is how i do it. Any other oil makers reading this i would appreciate your input as there are aways ways to improve
I hope anyone in need of oil has found this useful and you can see how easy it is to make.
That's it folks
