CBD Dosing Oil: CD-1 v1.0
Chemovar/strain: Candida CD-1 by Medical Marjuana Genetics 20:1 (14-20% CBD less than 1% THC)
This is my first CBD only oil. I’m excited to try it on it’s own and guage the results. Then i will begin to experiment blending it with the other dosing oils I have made which are THC high to find blends an balances that work best for me in different circumstances.
This kind of infused oil is a kind of tincture - technically an elixir in fact.
I’ve promised a new pic-tutorial so here goes!
I use a ratio of approximately 1g of dried bud to 1oz of carrier oil. This batch used only 1cup of oil.
- 8.6g dried and decarb’d bud
- 1cup/8oz/236mls Extra Virgin Olive Oil (preferably organic. A lot of Olive oil is actually really diluted with vegetable and/or other oils))
- 1TBSP liquid sunflower lecithin (“Now” brand purchased online. Must be liquid sunflower, not soy or granules)
Steps to making a dosing oil are (I’ll elaborate on each one below):
- An oven safe container for decarboxylating buds - unless you’re lucky enough to have a Nova . Magical Butter sell a decarb box, and I want one of those i think, but you can use any tray or a cake tin or baking dish. I wrap mine in foil (a la @InTheShed).
- An oven capable of maintaining low temperatures
- Infusion can also be done using a Magical Butter machine but this has a minimum of 2cups of oil, which is a lot of oil. Today I’m only making a cup full. A little goes a long way.
- A thermometer with an oven probe or an in-oven thermometer - oven thermostats are notoriously inaccurate.
- A mason jar for the infusion process
- A small funnel and some cheesecloth for straining the oil
- A tinted glass bottle for the final product and dropper bottle for dosing (or capsules).
- Use quality flower
- Decaboxylate the dried bud/flower (different temps apply for THC and CBD, see below)
- Infuse the decarb’d bud into a carrier oil
- Add liquid sunflower lecithin to the carrier oil (either before during or after infusion).
- Strain into a tinted glass bottle and place in fridge for 24hours.
- Use the @Oldbear designed spreadsheet to get a ballpark idea of the mg/ml of cannbinoids (or just give @InTheShed the relevant information and ask him to do it for you, like I do!)
You get better results with high quality resin encrusted flower. Using leaf and trim makes great oil too, but if you’re making a medicinal oil, using high grade flower means that the final product will have a lower amount of other plant compounds in it than an oil made from leaf and/or trim.
Here is 8.6 g of beautiful dried CBD flowers
Decarboxylate the bud:
This activates the cannbinoids, transforming them from the acid forms to the active forms (CBDa > CBD, TCHa > THC etc.). Acid forms have their uses too and I plan to make an infusion with non-decarb’d bud at some stage as well.
Decarboxylation occurs when specific temperatures are maintained for specific times. It is now well known that CBDa requires higher temps than THCa to decarb’. In the course I have just completed, Samantha Miller, cheif scientist at Pure Analytics, informed us that CBDa requires 295ºF (146ºC) for 90 minutes. At lower temps conversion will be either incomplete and sometimes not happen at all so she recommends doing your best to hit that temperature.
Opinions differ about whether buds should be covered for decarb or not. I cover them. I use Shed’s innovation of making a foil pouch that looks something like a Cornish pastie made out of foil
It’s advisable to put the herb in prior to starting the 90minutes to allow for drying time.
I also sometimes use this time in the oven to sterilise my jars and bottles - if you do this, make sure the bottles and jars go in when the oven is still cool, so they warm up slowly, and spend about 20minutes at 120-140ºC.
Once the oven is stabilised, relax while some chemistry happens.
Once this is done you can run the infusion stage straight away, but some oilers like to put the buds, unopened, in the freezer for 12hours as there is some thought that this helps to retain terpenes. There’s a whole thread dedicated to these efforts, which is beyond my capacity for engagement, but I’ve adopted the freezer stage and always had good results with my oils retaining some nice flavours of the infused cannabis. Using this freezer step means I like to run my decarb’ cycles in the late afternoon/evening, put the foil pasties in the freezer overnight and then run the infusion the following day.
A NOTE on decarboxylation:
This oil I’m making is with CBD rich flower which as stated requires 295ºC/146ºC.
THC requires only 212ºF/100ºC
Take out the cooked buds and place them into a 500ml Mason Jar. I use a clean spoon to crush them up a bit. You can use your fingers but it’s not so hygienic, plus the stem bits can get very sharp - don’t find that out the hard way like I did once!
Measure out 1 cup of carrier oil. I use Extra Virgin Olive Oil becasue that always gets reported as being the “best” for medicinal use because of it bio-availability. You can also use coconut oil, grapseed oil, avocado oil, hemp oil and probably more. It is possible that different oils would be better depending on how you take it (either ingestion or sublingual/buccal). I mix the methods up a bit so for now I’m continuing with EVOO - it’s been working with all methods of delivery for me.
Cover the jar with some tinfoil and use the screw on lid to keep it in place - this is why Mason jars are the specific choice here.
Place a tiny pinprick in the foil to allow for pressure regulation (I think that what this does - I don’t know, but it was recommended to me by a few folks and it works, so I don’t argue )
Heat the oven to about as low as it can go 80ºC is a good ballpark. You ideally dont wan’t it to get above 100ºC. I figure the Magical Butter machine uses 160ºF for infusing, which is about 70ºC so I aim for around there but my oven has trouble wth that and is usually around 90ºC. This seems to be ok. If you’re guage is Fahrenheit then around 160ºF is good
Infuse for 6-8 hours, shaking gently occasionally if you can, just to help the steeping (like jiggling a tea-bag). Doesn’t matter if you can’t do this.
Some oil makers on site have had success putting a pause in the middle of infusion time and letting things cool and sit for a while before running again (so 3-4 hours > cool > 3-4hrs). I didn’t do that this time, and have made plenty of great oil without it so you don’t have to. It can reportedly make a slightly more potent oil.
Liquid Sunflower Lecithin!
This is an imperative step for a dosing oil or oil for making edibles (which are effectively the same thing, used differently). The lecithin contains molecules that bind directly to both the cannabinoid molecules and the oil molecules, forming a bond between them. This allows the cannabinoids to piggyback their way into the system on the Olive oil molecules and makes them far more bioavailable. Don’t skip the lecithin.
Use anywhere from 1tsp to 1TBSP of liquid sunflower lecithin to every cup of oil used. I like to mix it in afterwards, right into the jar while the oil is still warm.
Stir it up till it’s well blended and then strain the oil into your bottle using the small funnel and some clean cheesecloth. I like to layer the cheesecloth a few times for a nice smooth oil (the pegs holding the cheesecloth to the funnel are another innovation I picked up from @InTheShed).
Then you have a bottle of oil!
This needs to go in the fridge for 24hrs to allow time for all the molecules to “combobulate” (not the technical term for it ). Basically as i understand it it takes sometime for the bonding effected by the lecithin to take place and 24hrs in the fridge will do this.
I keep my oil stored in the fridge and decant small amounts into 25-30ml dosing dropper bottles because this is how I like to dose it. It’s a good idea to let the oil come to room temp and give it a gentle shake before decanting into the dosing bottle.
The left over mash can be used to make brownies, cookies, cakes, or put into capsules or just added to food as a garnish. I used to do the garnish thing a lot but it’s good to be careful with it because more is not always more with cannabis, even CBD, so I have become less inclined to use it loosely. I don’t have the energy, canna-loving social circle or consumption capacity to do things like making brownies or capsules so my compost worms get the full benefit of the mash on most occasions
I can’t attach any more images to the post (limit of 10 attachments) but I’m about to post the process for the Topical Oil I just made (later today) so I’l include pics of the bottles there. I hope this was helpful to folks. I tried to make it pretty detailed because I plan to link a few non-members to it who may be interested to get into making their own oils.
If anyone notices an error or if something just isn’t clear pls let me know so I can edit/correct it!
My dear SHed, if you would be so kind as to crunch thos numbers for me please. I’m comfortable estimating that my sativa leaning Candida has close to 18% CBD (and I used 230ml of oil).
Topical oil process coming up soon.
8.6gr at 18% CBD and 230ml EVOO and 80% efficiency in a jar in the oven, gets you to 5.38mg CBD/ml oil.My dear SHed, if you would be so kind as to crunch thos numbers for me please. I’m comfortable estimating that my sativa leaning Candida has close to 18% CBD (and I used 230ml of oil).
I wondered about doing that actually - but then it’s just another thread to keep track of But it is a good idea - so I may.You should copy that and create a journal for it. I know thst took some time! Nice write up!
Wonderful tutorial! I'd go with the "bravo" emoji again but they're no longer on sale, so this will have to do:
I assume you’re meaning ºF Yes - i was surprised that it was so low when she said it. I did my topical oil that i’m About to post at 100ºC and it works, but in future I won’t stress if it climbs a little higher than that during decarb’.The only thing I noticed that I do differently is decarb for THC at 240º for 90 minutes in foil (to allow for the heat to penetrate to the buds) rather than 212º. That seems too low to me.

Thank you! That gives me a ballpark to work with. Without testing we can’t be very accurate so it might not translate directly to the potency listed on a commercially available product becasue our mg/ml may be a bit off. I’m comfortable with an approximation and think that so long as I’m using the same method every time my oils should be fairly consistent. And dosing is the same as with any product - start low and go slow
15mg/ml is my minimum for topicals .But I know that @InTheShed aims for 10mg/ml (i think - pls correct me if i’m wrong)
