So you strain the plant material and then re-infuse it with the oil you just strained out of it???
I use a conventional oven for my infusions. I’ll run an infusion all day and check from time to time that the temperature is good. Then I switch it off overnight and on again the next day.
I don’t go to the trouble of filtering it in between.
I actually run undecarbed (but dried) fan leaves and trim to build a base oil. This gives a broad spectrum of flavonoids and terpenes, but also a source of THCA. THCA has similar anti inflammatory effects to CBD, but without making it difficult to get high if you take large doses.
The base oil I run twice, then hit it with decarbed flower/spent press pucks/AVB (usually all at once). Then I run that a couple of times.
I’ve been using the oil in capsules and getting good relief. Lately I have been using it to make biscuits - CBD and THC versions from different oils produced the same way.
It’s delicious in food.
