Don’t waste FECO — every milligram of Full Extract Cannabis Oil you worked hard to make is worth saving. After evaporating a full liter of tincture in a large baking dish, there’s always sticky FECO residue clinging to the sides and bottom. In this guide, we’ll show you exactly how to reclaim every last drop and turn that “dont waste feco” mindset into a delicious infused drink.
What Is FECO and Why You Should Never Waste It
FECO stands for Full Extract Cannabis Oil. It’s made by taking Green Dragon tincture (cannabis soaked in alcohol) and slowly evaporating off all the alcohol — leaving behind a thick, potent concentrate. Because of its high concentration, even a small amount of leftover FECO residue stuck to your dish can pack a serious punch. This is exactly why “don’t waste FECO” is such an important principle for any home extract maker.
In this video, Herbistry420’s host 40 shows us how he made a couple of ounces of FECO using a large glass baking dish — no heat, just placing it in the oven (turned off) to evaporate over the course of a week. After scraping out the bulk of the FECO, a significant residue remained. Here’s how he reclaimed it.
Dont Waste Feco: 3 Proven Reclaim Methods
1. The Warm Milk Method (Best for Large Batches)
This is the most effective way to dont waste feco after a large batch extraction:
- Pour approximately 300 ml of whole milk (or full-fat coconut milk) directly into the dish with the FECO residue
- Place the dish in the oven on the lowest temperature setting (50–70°C / 120–160°F)
- Leave for 10–15 minutes until the residue becomes liquidy
- Use a silicone spatula to scrape and stir all sides and the bottom
- Return to the oven for another 30 minutes at the lowest setting
- Remove and carefully pour the infused FECO milk into a storage container
