Lay a clean tea towel down on the bottom of the crockpot. This will create a buffer between your mason jars and the crockpot, potentially preventing any jar from moving or cracking during cooking.
Fill your crockpot with enough warm to hot water to cover the top of the mason jars you plan on using by an inch to create a water bath.
Place the digital instant-read thermometer into the water. Start the crockpot heat on high. When a temperature of 185°F is reached, turn the crockpot to low.
While the water bath is heating in the crockpot, measure and decarb the CBG-dominant cannabis flower in the oven at 220° F for 60 minutes.
Evenly divide the MCT oil between the mason jars you plan on using. You can either use pint-sized or half-pint-sized jars; it's you're preference; just be sure they fit in your crockpot. No matter the size, be sure to leave a ½ inch headspace from the top.
If you plan on using sunflower lecithin, add it to the mason jars now.
Evenly divide the decarbed CBG flower between the MCT oil-filled jars. Wipe the rim of the jars with a clean towel and place the lid on. Tighten the metal ring to finger-tip tightness; it does not have to be tightened all the way. Do not tighten too tightly.
Once the water bath has reached a temperature of 185° F, carefully place the jars into the water bath.
Place the lid on the crockpot and leave it alone to infuse for 4 hours.
After 4 hours, carefully remove the lid, followed by the jars from the hot water. Set them aside to cool.
Once cool enough to handle, you will want to strain the cannabis oil through a paper filter and funnel, cheesecloth, or French press to separate the plant-matter from the infused MCT oil.
Save the leftover pulp for use in future recipes. Then return the prepared CBG oil to whatever jar you would like to store it in, like an amber glass jar with a dropper.
Store the prepared CBG oil in a cool, dry place. It will last longer if stored in the refrigerator and even longer if stored in the freezer.
Temperature Control: The water bath does not need to stat perfectly at 185° F the entire time. Any temperature between 170°-190°F is OK.
Safety First: I recommend you sanitize your jars by keeping them submerged in the 185° F crockpot for 10 at least minutes. This step is not necessary, but good practice for safety and hygiene.
Floating Jars: Sometimes the mason jar will float when placed in the water bath. This is no need for concern, simply put something heat and water safe over the top of the jar to weigh it down, a clean rock works well.
