The math for milligram is not so hard. 1000mg of flower with 20% THC in it is: 1000mg x 20% is 200mg. total thc.
Most recipes i see call for 1 cup of oil, 1 cup of flower. But if you don't use a whole cup just try to keep the ration 50% flower/50%oil.
Or for every 1000mg of flower you use about 10 grams of oil, so 3 gram flower is 30 gram oil
So if i take 1 gram flower and 10 gram oil that would be 5 portions of 40mg thc, and if i take 4 portions of 2,5 gram oil i have 50mg thc portions.
My oil method in a nutshell.:
- break down the weed in smaller chunks but dont grind
- decarb the chunks of weed in the oven at 115 celsius / 240 fahrenheit for 35 minutes.
- i put the chunks of weed in a tea glass and add enough oil to cover the herb.
- I put a big pan with water on the stove close to boiling point.
- Inside this big pot of hot water i put a smaller sauce pan with some water
- inside this small sauce pan of water i put my tea glass with herb/oil mixture
- i leave it gently heating up for 3 hours.
You may put a lid on the tea glass and you have to add some hot water if the water in the pan starts to evaporate.
If you want to make oil for 2 or 3 different strains make sure you put them in seperate glasses and label them or write down which is which.
If you are interested in some recipes i found this youtube channel on how to make cannabutter and how to make edibles.
I asked her for a gummy bear recipe and she is working on it.
