coconut oil extract didn't work at all

[moeburn]

I've read where during cooking the thc starts to degrade at temps above 250. Particularly if its cooked for a long time. There's no reason to have a high temp during oil cooking a low simmering cook will do just as well. All you really need is get it warm enough to mix well with the oil and then its ready. Cooking it longer doesn't help anything and justs results in less potency.

So what temp, and how long?
