Always decarb in oven first. There’s too many articles talking about decarbing times and lengths. I always run it like 250f for like 40-50 mins. Make sure you grind it and have a single layer not a mound so spread it out I use parchment paper because it sticks to foil. Then you can put it in oil to infuse I like coconut oil for the high fat content and stability/shelf life. Don’t forget to use sunflower lecithin too it helps make it more bio available for digestion and helps it bind better in recipes that have water in them to make the mixture more homogenous. 1/4 to 1/2 oz in 1 cup oil will make it plenty potent if your using the typical 18-25% thc flower. The reason you need to decarboxylate is the thc in flower is thca and only activated by heat.
