Why You Will Love This Guide

Edibles are a great way to consume cannabis to relieve unwanted symptoms, but if you’re buying them from a dispensary, the costs can add up.

That’s why so many of my Well With Cannabis Community members love to save money by making edibles at home.

This can be done with a simple infusion of cannabis flower and fat like butter, coconut oil, or olive oil to make weed butter or weed oil.

But the same question is always asked: how much cannabis and oil should I use?

It’s a great question because how much of each you decide to use will impact the potency of your final product.

This guide will discuss determining the perfect flower-to-oil ratio for your infusion to get your chill on and save money!

How to Use The Ratio Chart

The easy-to-use chart above will help you decide how much flower and oil to use based on how big you want your final batch to be.

This works for infusions made in a crockpot, Instant Pot, or even an infusion machine, depending on the capacity it can hold.

The chart has two parts: a 1:2 ratio (1 ounce to 2 cups) and a 1:1 ratio (1 ounce to 1 cup).

But which chart should you use?

One of the best parts about making infused butter is that you can make it as strong or mild as you prefer.

If you have a low tolerance or are looking for a small dose, you should use the 1:2 ratio chart listed first.

If you have a high tolerance or want a stronger dose, you can reference the second chart and use a 1:1 ratio.

For a 1:1 example, one ounce of decarboxylated flower will be mixed with one cup of butter.

This will create an infusion twice as potent as if you used the 1:2 ratio.

When deciding which ratio to pick, consider your tolerance, and if you’re new to edibles, be sure to follow the golden rule of “start low and go slow.”

Other Factors to Consider

As a general rule, it’s essential to know that the more cannabis flower you add to your infusion, the more potent your edibles will be.

You can also increase the potency by decreasing the amount of oil or butter to get the same effect.

My flower-to-oil ratio chart above breaks it down so you can easily and accurately mix the right amounts – but there are a few other factors to consider.

The Potency Of The Flower

While the amount of flower and oil you use matters, so does the potency of the flower you use.

Cannabis flowers can contain 0-30% cannabinoids or the important compounds we want, like CBD, CBG, and THC.

Different strains can have different percentages of cannabinoids. Without lab testing, it is impossible to know this exact number.

If you purchased cannabis from a dispensary, it should come with a lab report or printed number stating the total percent of cannabinoids in the product.

If you grew your flower and know the strain you used, online resources like Leafly should be able to give you an average percentage of what the strain typically produces.

Remember, the higher the percentage of cannabinoids, the more potent the final infusion will be.

If You’re Working With Trim

The chart above was designed with the thought that you would be using traditional cannabis flower buds.

But what if you want to make an infusion with trim or shake?

If you’re working with trim, I recommend doubling the amount of flower in the cart.

This is because trim, like fan leaves or sugar leaves, is typically less potent than flowers, so doubling up on the amount will help keep the potency higher.

Of course, this is just a rough guesstimate and will again depend on the strength of the flower and your personal tolerance.

You can repeat the same process if you work with CBD flowers to make CBD cannabutter.

If You’re Working With Kief

Again, the chart above was designed for using cannabis flower buds.

However, if you’re lucky enough to have collected a nice amount of kief, you can easily infuse it into butter or oil.

If you’re working with kief, I typically recommend you *at least* halve the amount of “flower” in the cart.

This is because kief has the potential to be anywhere between 50-70% more potent than traditional cannabis flower due to its high trichome content.

Take care when preparing kief oil or kief butter, as they can be very potent depending on how they are made.

A Calculator Can Help

While it is no substitute for lab testing, an online calculator can help you determine the potency of your final product.

For this to work, you will need to know the potency of the material you are working with or at least have a general idea.

You can input values into my edibles dosage calculator and see the final potency before infusing.

Get To Know Your Tolerance

By changing the amount of flower to oil in your recipe, you can manipulate the final product to be as potent as you’d like.

The more flower you use, the more potent it will be. The more oil you use, the more you will dilute the infusion.

Since cannabis affects everyone differently and the endocannabinoid system is highly individualized from person to person, it’s essential to know your tolerance level.

Cannabis enthusiasts agree that the best way to consume THC edibles safely is to “start low and go slow.”

That way, you are less likely to experience the unpleasant side effects of too much THC consumption, like anxiety and paranoia.

It’s always advised to start with a low flower-to-oil ratio for your first batch of edibles and see whether it meets your needs.

If it’s not as potent as you’d like, you can try a stronger ratio next time.

To find the perfect ratio for your tolerance level, experiment with different amounts of cannabis flower and oil.

Once you’ve got the right potency, you’ll be able to make all kinds of edible recipes at home on your own.

Traditionally, cannabis brownies are a fan favorite, but you can make anything from cookies and candies to no-bake edibles and more with your infusions.

Whether you’re just beginning your journey into homemade cannabis-infused treats or if you’re a seasoned baker, this flower-to-oil ratio chart will help as a quick guide.


In wrapping up, I want you to embrace the flexibility and control that homemade infusions offer.

Not only do they provide a cost-effective alternative to store-bought edibles, but they also allow you to fine-tune the potency of your recipes to fit your specific needs.

Remember, the quality and potency of the material you start with and the precise ratios of flower to fat play an important role in determining the strength of your final product.

Using tools like my edible dosage calculator can offer a rough estimate of the potency of your final product, helping to avoid the common pitfall of overly potent or underpotent edibles.

Now that you’re ready to make your own infusion, it is time to get excited about the variety of recipes and products you can create.

The possibilities are endless, from classic brownies to savory dishes and even non-bake treats.

Enjoy the process, stay curious, and here’s to creating delightful, potent, and, most importantly, safe cannabis-infused treats right from the comfort of your own home.

  1. Karen, thank you so much for your kind words and for sharing a bit about your journey with me. It means so much to know that the format of my content has resonated with you, especially as you navigate making tinctures for your son with epilepsy. I’m humbled that I could be part of your journey 😊

  2. What is the purpose of a water bath in the crockpot? Why can’t the oil and flower be mixed in the crockpot and set on ‘low’ which should be adequate heat? Then strain the whole thing and jar it up?

  3. Thank you so much for reaching out with your question, Cynthia! Using a water bath in the crockpot helps maintain a consistent and gentle heat. This method reduces the risk of overheating, ensuring that the beneficial compounds are preserved. While mixing the oil and flower directly in the crockpot set on ‘low’ might be OK, the direct heat can create hotspots, potentially leading to uneven heating and the degradation of quality. Cleaning up without using a water bath can be a bit more cumbersome, and straining the mixture may require an extra helping hand, but that’s not to say you can’t do it this way. It’s all about finding the balance that works best for you. Some prefer the direct method for its simplicity, while others opt for the water bath for its consistency and control over the temperature. I hope this clarifies things a bit! If you decide to try either method (or both!), I’d love to hear about your experiences.

  4. I’ve been looking into making my own cannabis oil at home, and everything I’m reading is showing 1/8 ounce decarboxylated cannabis to 1 cup of oil.

    Does 1:1 cannabis to the cup really pull a much stronger thc content without reaching a saturation point of the oil? I’d like to make hard candies, and there’s a limit to how much oil I can put into them.

    I don’t want to sound skeptical, I just want a very strong oil I can make safely. I believe by my rough calculations on what I have (25% THC), I’d end up with something like 90mg of THC in 1 cup of oil, or 4312mg for the whole batch.

  5. HI Eamon. In my experience, oil saturation isn’t typically a concern with cannabis, especially when you use oils with a higher fat content, which can effectively absorb THC. The 1:1 ratio, or even 2:1, should allow you to create a very potent oil without hitting a saturation point.

    However, I’m curious about your calculations. Could you share more about how you arrived at the 90mg of THC in 1 cup of oil, or 4312mg for the entire batch? Understanding your process might help us offer more tailored advice.

  6. Hi Emily-

    I was wondering about a Feco to butter ratio. I want the more potent, I use the 1:1 flower ratio.
    I use it for edibles for insomnia.
    Thanks for all your great recipes, tips, and all you do!!!!

  7. Hi April. For a more potent result using FECO (Full Extract Cannabis Oil), consider starting with a ratio of 1 gram of FECO to 1 cup of butter. This is stronger than the 1:1 flower ratio you’ve mentioned, but don’t hesitate to experiment a bit to find the perfect balance for your needs.

    Thank you so much for your kind words and for reaching out with your question!

  8. I made some infused olive oil to drizzle over my salads. It was far too strong. Spent the night fighting existential demons. Ouf !
    Can i dilute with more oil ?

  9. Absolutely, you can definitely dilute the potency by adding more oil to your infusion. This should help mellow out the intensity. Additionally, if you’re looking to counteract the effects of THC, incorporating CBD can help balance things out. Hopefully after dilution, your oil will be more enjoyable for salad drizzling!
