Let me show you how I make FECO (full-extract cannabis oil) capsules by decarbing, making a tincture, running that tincture through my Extract Craft Source Turbo to reclaim the alcohol and reduce it down to a thick FECO oil, and then filling size “00” capsules by hand with the help of a small syringe. From start to finish, it’s my favorite way to turn a jar of flower into a discreet, swallow-and-forget medicine cabinet staple.

Why You Will Love This Guide

If you’ve been in my Well With Cannabis Community for any length of time, you already know FECO is basically my ride-or-die extraction. I’ve made it the old-fashioned way in a mason jar on my counter more times than I can count, and I still love that method for people just getting started.

But once I got my hands on the Extract Craft Source Turbo, my whole process changed, less alcohol smell in my kitchen, less babysitting a crockpot, and a cleaner final product.

So I filmed a reel showing exactly how I do it now, and I wanted to put the full write-up here too, because I know you like to pause, re-read, and take notes (I do too).

This isn’t a replacement for my full FECO guide or my cannabis capsule guide, think of this as the “here’s exactly what’s happening in my kitchen this week” version, using the tool I’ve genuinely swapped in for my everyday FECO making.

Instructions 

  • Step 1 – Decarboxylate

    This step never changes, no matter what method I'm using. Before any extraction, my flower gets decarbed low and slow so the THCA or CBDA converts into the active THC or CBD I actually want in my final oil. I typically bake mine at 240°F for about 40 minutes for THC flower, adjusting time and temp depending on the cannabinoid I'm working with. If you need the full breakdown by cannabinoid, I've got exact times and temps in my FECO guide.

  • Step 2 – Make a Tincture

    Next, I make an alcohol-based cannabis tincture — the same first move as my traditional FECO method. I place the decarbed flower in a mason jar and cover it completely with high-proof grain alcohol, then seal it up and let it sit in a cool, dark place. Depending on how strong I want it, I'll let it soak anywhere from 24 hours to a few weeks, giving it a gentle shake every so often.
    Once it's done soaking, I strain the tincture through a coffee filter or cheesecloth into a clean jar, separating the plant matter from the liquid. This strained tincture is what goes into the Source Turbo next.

  • Step 3 – Reduce with the Source Turbo

    This is where my process has changed the most. Instead of putting the strained tincture in a mini-crockpot water bath and babysitting it for hours, I pour it into my Source Turbo, which reclaims the alcohol and reduces the tincture down for me — with way less odor and way less hands-on time. What's left behind is that familiar thick, dark, sticky FECO — the same "black gold" I get with my traditional method, just with a cleaner process to get there.

  • Step 4 – Fill Your Capsules

    This is where FECO becomes something I can actually take without wincing at the taste. FECO on its own is intensely bitter, so putting it into a capsule is my favorite way to use it.
    Here's what I personally do:
    Warm the FECO slightly so it's easier to work with — never in the microwave, always a gentle double-boiler style warm-up.If it's too thick or sticky to draw into a syringe, I mix in a few drops of MCT oil or another carrier oil to loosen it up.Using a glass syringe, I add a small amount of FECO to each capsule, remember, a dose is often just about the size of a grain of rice. I fill the rest of the capsule with a carrier oil like MCT or olive oil, which also helps with absorption since cannabinoids are fat-soluble.Seal the capsules and give them a wipe down before storing.
    If you've never filled a capsule before, I walk through the whole process — including flower-filled and oil-filled capsules — in my cannabis capsule guide.

  • Step 5 – Dose & Store

    FECO is one of the most potent things I make in my kitchen, so I always follow my own golden rule: start low and go slow. Because I don't have access to lab testing, I use my edible dosage calculator to get a reasonable estimate based on how much flower I started with.
    Storage: I store my finished capsules in an amber glass jar in a cool, dark place — the fridge or a cabinet away from light and heat both work. Properly made and stored, they'll keep for months.

Notes

Amounts: You do not need to use the full 14 grams of cannabis called for in this recipe. You can use as much or as little cannabis as you want. Just understand that your yield will be very small, as little as 1mL, and dependent on how much cannabis you start with. You also do not need to use the full 8 ounces of alcohol, you just need enough to cover all of the cannabis in the container you are using. Anything more is a waste.
Alcohol: Only use high-proof alcohol; the higher, the better. Lower-proof alcohol, like vodka, is not ideal. Use this guide to find high-proof alcohol, if needed.
Soak Times: I’ve seen traditional, long-soak tinctures steep anywhere between a few hours to up to 6 months, or longer, in some cases. Soaking your plant material for longer will slightly increase the potency but will also increase the amount of chlorophyll and plant matter in your final infusion.
Evaporation Options: If you want alternative options for evaporation, follow this guide on how to evaporate the alcohol safely.

Why I Switched to the Source Turbo for FECO

I’ll be honest with you, for years my process was a mason jar, a mini-crockpot, an open window, and a lot of patience.

It works, and it’s still exactly what I teach beginners in my original FECO guide. But it also meant my kitchen smelled like alcohol for an afternoon and I was constantly checking on a jar sitting in a water bath.

The Extract Craft Source Turbo changed that for me. I still make my tincture the same way I always have. that part doesn’t change. What’s different is what happens next: instead of a crockpot water bath, my finished tincture goes into the Source Turbo, which reclaims the alcohol and reduces everything down for me, with way less mess and way less odor.

For this reel, I wanted to show you my exact process from flower to finished capsule, using the tool I actually reach for these days.

My Honest Tips

  • Strain thoroughly. The cleaner your tincture going into the Source Turbo, the cleaner your final FECO.
  • Ventilation still matters. Even with the Source Turbo doing most of the work, I keep a window cracked or a fan running during reduction.
  • Weigh everything. I write down my starting flower weight every single time, because it’s the only way I can get close to an accurate dose later.
  • Start with one capsule. Wait at least two hours before deciding whether you need another. FECO sneaks up on you.

Frequently Asked Questions

Do I need the Source Turbo to make FECO capsules?

No, my original FECO guide walks through the traditional mason jar and crockpot method for the reduction step, which works great. The Source Turbo is simply the tool I’ve personally switched to for a cleaner, more hands-off process once my tincture is made.

Can I use CBD flower instead of THC flower?

Yes. The process is identical, just start with a high-CBD flower if that’s the cannabinoid you’re after and decarb for a total of 90 minutes.

How strong are FECO capsules?

Very. FECO is one of the most concentrated products I make, which is exactly why it goes so well in a capsule, a tiny amount, precisely dosed, no strong taste.

How long do FECO capsules last?

Stored properly in an airtight amber glass jar in a cool, dark place, mine typically last several months.
