Yes, a big thanks to @Moe.Red. Any contribution is more than welcome, and appreciated. I am making this thread to benefit us all.Big thanks to @Moe.Red for the link to this thread. I'm here to learn. Thank you in advance to all who share your experiences.
I've made my own cooking oil, effective. Let's me sleep 7 hours so that's worth a lot
Next, I want to fill my own cart's. I'm tinkering around currently with this goal in mind with not much luck, yet

Preferred strains is a whole other subject, except if going for mass qty. The beauty of this med is in it's delicacy, a subtle push on this cannabinoid paired with this terpene and you have a different experience. I try very hard to maintain that experience thru the entire extraction. I think of it as a purified RSO. Everything on the plant that is soluble in ETOH makes it from the moment of harvest to the capsule in a very short time. The temp never exceeds room temperature, and in fact the plant is generally at -40C during this whole process. When you start with freeze dried buds you harvested today, something approaching 100% of the stuff we want is retained in the process. The result has no water, making the cold ETOH baths even more effective.Suggested topics we can cover:
Extraction (I am sure I missed lots. Please fill in the blanks)
- Preferred strains best suited for ethanol extraction. THC / CBD / THC-CBD / CBD-THC
- Flower / trim prep prior to 'soak'. Example: dry at what temp and time. Methods of drying. Air, freeze dry, oven..... and why freeze drying is best
- Solvent choices with Pros/Cons
- Ratio of Biomass to Solvent to achieve full extraction. Example: Bio by WT and Solvent by Vol.
- "Did I get it all?" any indications all medicine has been extracted. "Do I keep washing 'till solvent clear?" How much solvent is too much and being wasted?
- 'Soak Time'. This differs depending on desired result. Lets start with 'Getting It All'. Then maybe quick-wash and other techniques.
- Pre-evaporation refinement proceedures. Such as Winterization and sub-zero vacuum filtration. Buchner funnel usage, filtering mediums such as diatomaceous earth and charcoal.
- Tips on conserving solvent and storage
Evaporation
- Safety First - VENTILATION! ...............
- Must have equipment/tools/glassware/hydrometer if recovering solvent (high proof, not beer or wine)
- Evaporation methods/equipment. $Poorboy Rig, $$Source Turbo, $$$Rotovap
- Maybe a brief "Advantages of evaporation under vacuum". Solvent recovery, less chance of accidentally damaging batch with heat, retaining desired elements ...........
- Degassing? Is it needed? Why? How.
- I know I missed lots, its late
I press all my flower into rosin personally. Then I put it in parchment paper into a Mason jar then into the freezer. I think you should be able to do the same with your ethanol extracted concentrate.My extraction method of choice is soaking in ethanol. Reason being is that I want my concentrate as clean and natural as possible. If any residual solvent, Everclear isnt harmful if ingested.
My extraction method.
Please let me know if I am doing something wrong or missing a step(s)
Is it worth the cost and effort to dehydrate the Everclear prior to extraction? Other than the finished oil having a slightly higher viscosity, is there an advantage of using anhydrous ethenol? Is a molecular sieve inert chemically? Sulfates are out of the question, so I will not go that route.
How do I know I have pulled everything? Flavor is secondary, THC/CBD content is primary. I want to ensure I am leaving nothing behind. Should I continually soak/wash the flower until solvent is clear? I winterize after extraction, so I dont care if undesirables are pulled as well. They can be removed. And I am recovering the solvent. So I dont mind using lots.
Once I have my extraction method down and efficient, I will then worry about retaining terps for flavor.
To verify my method is extracting all available THC/THCA, would I have to send samples to a lab? Or is there a way I can confirm myself? I am thinking these would be required:
1) Sample of raw un-processed flower (determine available THC/CBD)
2) Sample of extracted concentrate
3) Sample of processed flower (extraction efficiency)
Could somebody recommend a lab with integrity in B.C.? What is the cost of such testing?
STORAGE
The reason I moved from smoking flower to smoking/vaping oil is that I am a heavy cigarette smoker as well. Quitting ciggies would be optimal, but it aint happening anytime soon. Tried. So in the quest to reduce tar and carcinogen intake, I am moving to concentrates. With that said, I have to purchase flower in rather large personal quantities to be able to afford my meds (0.25lb-0.5lb). So I have to store it for some time.
Meds you might say? Yes. I am sure glad Ritalin wasnt quite the thing yet when I was a kid. I would have been the Poster Child for the ad campaign. In my mid 50s, I still struggle with ADHD today . Although I believe my cannabis use has held me back in in some aspects of life, it has also been my savior.
What is the best way to store concentrates? Vacuum sealed in freezer? How long can Full Spectrum Oil be stored and still retain core properties?
