Wow, making butter today, not sure of the potency. I'm using 2 pounds of butter with 6 oz of shake and 1 oz of bud. Will this be OK?
If your weed is 28 grams after decarbing, you did decarb, right? And it's 15% thc that would make each gram 150mg times 28 grams and it's 4200mg.
6 ounces of shake is 168 grams. If you estimate it's 5% thc and it could be less, each gram would be 50mg, and 50mg times 168 grams is 8400mg.
8400+4200= 12600mg or 6300mg per pound of butter. An ounce is 6300 ÷ 16 oz = 397 mg per fluid ounce.
Keep in mind these are only estimates and the numbers can vary widely based on estimated percentages. And the decarbing makes a huge difference, unless done properly these numbers could be way off.
Decarbing in butter doesn't work well. In the oven 40 minutes at 240°F is what most people use.
Decarbing in oil or butter doesn't work well because the oil insulates the cannabinoids. Same reason baking brownies at 350° doesn't ruin them.
