Rosin dab

While pressing the hash to flatten it out, Salazar noticed that resin started spewing out the side, leaving the original hash dry and unusable. Thinking he may have stumbled upon a new technique, he took a piece of hash, put it between parchment paper, and pressed it against a hot dab nail . Then came the oil, now known as rosin. He began using a hair straightener after experimenting with his wife’s hair curler. She suggested he then use the flat-iron tool, and after running out of hash, began using buds. The oil came out the same way.

In the few years since, rosin production has evolved to using screens and an industrial press to make mass quantities and more consistent products.

Consumer Preference for Rosin

Why do some prefer rosin? Although it’s a slight misnomer, rosin is known as a solventless technique because it doesn’t use any external solvents to dissolve the trichome. However, natural hydrocarbon terpenes act as a solvent. Thus, the only “solvents” left are the natural hydrocarbon terpenes from the trichome glands.

Rosin can turn low-quality hash into a dabbable wax. It’s also a very quick process compared with other extraction methods. It doesn’t require time in a vacuum oven to purge out residual solvents. It can be made safely at home with minimal investment, allowing home growers to make the most of their trim , typically a byproduct that’s thrown away.

Rosin Input Material

A variety of input materials can be used to create rosin. The input material can affect how many plant contaminants are left in the rosin, which can therefore affect the quality of rosin. Rosin from a flower is going to be different from rosin from kief or ice hash, for example.

Rosin from buds typically has some contaminants in the form of plant material that makes it through to the final product. They tend to be small pieces, but they can make a big difference to the flavor when dabbing rosin . The plant material will add a layer of burnt flavor to the overall experience. To avoid having too much plant material in your rosin, try using a rosin screen or mesh bag.

Dry Sift Kief or Hash

Rosin from kief adds an extra step to the preparation but tends to be cleaner, as the trichomes are removed from the buds prior to exposing them to heat and pressure. This extra step ensures that no plant impurities make their way into the final product.

Bubble Hash Rosin

Rosin from bubble hash is a great way to make use of lower-quality hash that does not fully melt as a result of plant contaminants. While you would not want to rosin 5-star or 6-star hash, rosin is a simple way to make your non-dabbable one to two-star hash into a flavorful dab.

Fresh Frozen Ice Hash

This process makes live rosin, which is highly sought after due to the high cannabinoid and terpene retention of the fresh frozen cannabis. Similar to live resin — butane hash oil made from frozen buds — live rosin is rosin made from frozen buds.

While flowers that were frozen directly after being harvested are considered “live,” to get to live rosin, you’ll need to first make ice hash with the fresh from plant material. If the resulting ice hash concentrate falls between a one- and four-star rating, it can be placed into a bag and put through the rosin production process to create live rosin. The end result is a strong and flavorful pure concentrate.

Live Resin vs Rosin

Although the terms are distinguished by a single letter, there’s a major difference between live rosin and live resin. While rosin is considered to be a solventless extract, live resin refers to a solvent-based extract, usually BHO, that is made with live or freshly frozen plant material. With the live resin process, a single-pass extraction is used to capture the plant’s terpene and cannabinoid profile by processing the resin glands before the plant is dried and cured. For live rosin, the chemical profile of the plant variety is maintained without the use of solvents, offering a flavorful concentrate without the use of potentially hazardous chemicals.

Making Rosin at Home

Making your own rosin at home is incredibly easy and fairly safe, unless you’re prone to burning your fingers while holding a hot iron (it happens). To make your own rosin, you’ll need specific equipment and to follow a few simple steps.

Equipment Needed

In order to make rosin at home, you need to collect the following starting materials :

  • A hair straightener or press, preferably with 2-inch-wide heated plates and a temperature display
  • Parchment paper
  • Filter bags (optional if using flower, but required if using any type of hash)
  • Cannabis material (nugs, dry sift, bubble hash, etc.)
  • Dabber to collect the rosin
  • Heat-resistant gloves (optional, but recommended)

Rosin Step-by-Step

Next, follow these steps to make your own rosin at home.

  1. Break down the plant material. Buds should be properly cured and not wet or too dry.
  2. Place the plant material into a teabag-like filter, preferably nylon food-grade screens or a mesh bag. This is optional for flower, but required for hash.
  3. Set the temperature on your hair straightener or press. A lower temperature of 180-220 degrees Fahrenheit, or 82-104 degrees Celsius, will yield less rosin that tend to produce a sappy or buddery consistency. Higher temperatures of 230 to 250 degrees Fahrenheit, or 110-122 degrees Celsius, will give the highest yield with a more flavorful and stable consistency, like shatter. Start with low temperatures and work your way up.
  4. Place your bag or loose flower in between two pieces of parchment paper. Use only as much material that will fit under the heating element, about one-fourth the size of the parchment paper. Do not overfill! Make sure to leave a couple of inches or centimeters of extra parchment paper on all sides to catch the rosin that is produced.
  5. Wear optional heat-resistant gloves and press the parchment paper with the preheated straightener or plates for between four to 30 seconds. The time depends on the quality of the flower and temperature used, and pressing firmly with the straightener laying flat like a stapler will generally yield better results. This may take a few times experimenting to get the hang of it.
  6. After removing the flower from the parchment paper, check the amount of oil. If you’ve got a low yield, you may need to place the parchment back under the straightener and repeat the process once or twice more. If that doesn’t do the trick, consider raising the temperature, applying more pressure, or spending a few extras seconds pressing the product.
  7. Once you have pressed your product, use a dabber to collect the rosin.
  8. Package or store the rosin for later use, or turn it into rosin taffy by stretching and pulling it, resulting in a taffylike consistency also referred to as snap-and-pull.

Rosin Equipment

Although you can keep rosin production simple with a hair straightener at home, cannabis enthusiasts may want to go the extra mile. For commercial rosin production, manufacturers use a similar step-by-step process, but with more expensive equipment and a few added steps. A lot of rosin equipment and techniques exist out there, including press kits, hydraulic presses, handheld presses, heater controllers, and more. Some come with extra-large plates, multiple plates, and include up to 20 tons of pressure that are capable of applying up to 3,000 pounds per square inch (PSI) of pressure on both plates. They aren’t cheap, though. Prices for rosin presses range from $300 to more than $4,000.

Consuming Rosin

A little bit of rosin goes a long way. Once you’ve made your rosin at home, you can smoke it in a glass bowl or joint, dab it in a rig (the preferred method) or vape it in a pen made for concentrates.

Remember, this is a highly concentrated product full of cannabinoids and has a robust terpene profile . Start with a small dose and work your way up. For medical patients who need fast-acting cannabis, rosin is an easy way to fast-track the plant’s healthful properties.

Aside from immediately consuming rosin, you can also use it in edibles and topical treatments.

The resulting concentrate when heat and pressure are applied to the cannabis plant. Rosin is a desirable technique because its concentration doesn’t require the use of external solvents.

What Is Rosin?

If you’re going to make Rosin, it’s a good idea to know what you’re getting! Rosin is a solventless (that means no chemicals) cannabis concentrate that you can make at home. Since it’s solventless, it’s a lot safer than concentrates that use solvents like BHO, Shatter and Wax. Rosin is versatile; you can place it on flowers as a “topper”, or you can smoke it as a “dab” if you have the appropriate equipment. In fact, if you’re looking to turn your weed into a dab-able concentrate, rosin is a great way to go.

Rosin vs Resin vs Live Resin

If you’ve been to a dispensary, or if you’re active in the cannabis niche online, you’ve probably heard of these three similar sounding things. They’re actually pretty different from each other, but it’s not as complicated as people make it seem.


Rosin is the result of putting cannabis under intense heat and pressure. If you stick some weed between two hot plates and press the plates together as hard as you can, a golden/golden-brown substance will be left over and that substance is rosin!


When you hear the word resin, it can refer to one of two very different things. One usage refers to “the sticky stuff” on your plants, aka the trichomes. This is the stuff you can collect in a grinder as “kief”. You could also use cold water to agitate resin off your weed (bubble hash) or freeze the trichomes off your plant matter (dry-ice hash).

Resin also refers to the black sludge left over in bongs and pipes after extended use. This type of resin is also called “reclaim”, and many people smoke this leftover gunk so they don’t waste weed. Although this can be effective in a pinch, it’s about as gross as it sounds and we don’t recommend using it. The stuff is sticky and stinky (not in a good way) and it stains anything it touches.

Live Resin

As the newest kid on the block, Live Resin is the most sought-after of these three. Live Resin is a concentrate made from freezing a newly harvested plant then using additional means to extract the trichomes from the plant. This is usually done with a solvent and it takes some sophisticated equipment to do.

Wait, I’ve heard these names before…

If you think you’ve heard the terms “Rosin” or “Resin” before, it’s because you probably have! The lack of legal legitimacy makes it so that many of the terms we use as cannabis growers are repurposed from other stuff.

  • Rosin refers to a substance used on the bows of cellos and violins. Rosin makes it easier for the bows to grip the strings of their respective instrument.
  • Resin is a thick substance made by plants that is usually composed of terpenes. This definition is perfect for what we’re talking about, but Resin can also refer to the sticky stuff from any plant.

Rosin vs Bubble Hash/Kief/Dry Ice Hash

There are already a ton of cannabis concentrates, so it might be hard to remember what the difference is between them. Here’s a really quick breakdown of some differences between some of the heavy-hitters:

Rosin (left), dry-ice hash, bubble hash, kief (right)


  • Made with high-heat and intense pressure.
  • Makes a strong, sticky substance that you can dab or put on flowers

Bubble Hash

  • Combine weed, ice-cold water and agitate to make Bubble Hash
  • After drying, you’ll have a crumbly pile of tiny, super-potent pebbles and dust
  • Learn how to make Bubble Hash
  • This stuff just falls right off of dry cannabis if it’s agitated enough
  • Makes a golden-green powder that can be sprinkled on flowers

Dry-Ice Hash

  • Like Bubble Hash, but uses Dry-Ice instead of cold water
  • Dry-Ice Hash is essentially Kief, but using dry-ice makes the process more efficient
  • Learn How to make Dry-Ice Hash

If you’re going to make your own homemade rosin, there are two main methods: you can use a dedicated Rosin Press, or you can use a hair straightener. Both these methods will work, but they each have their strengths and weaknesses. Let’s go through each method of making rosin and some of the pros and cons of each technique.

Before You Start Making Rosin…

Rosin is just plain great! It’s impressive, fun to make, and even more fun to use. However, before you start on your rosin making journey, there are a few important pieces of information you should know:

  1. Rosin is weed intensive. It takes a bunch of weed to do, and if you’re lucky with a high-quality hydraulic press and a cooperative strain, you’ll get 25% of your weed-weight back as rosin. In my experience, a hair straightener should return between 5%-10% while a non-hydraulic press (like the one I use in this tutorial) will get you 8%-17% That number can get a little higher or a lot lower and that largely depends on your rosin press, your technique, and the weed you start with. Some strains will make lots of rosin, and some will make very little. Seriously, your weed will make a huge difference in determining how much rosin you can press out of it.
    1. If you harvest lots of weed at a time like with this method, you can make rosin without much worry.
  2. Making rosin involves high levels of heat. Be careful not to burn yourself during the process of pressing, no matter which method you use.
  3. You will have to experiment a bit. Although you can use the default settings provided below, you’ll do even better if you test out different strains, temperatures and length of pressing time.

How Much Rosin Will I Get?

This is a common question growers have before they invest their homegrown weed into making rosin. There isn’t an exact answer since no one can predict the future, however, there are a few factors that will give you a good idea of what to expect from your next pressing.

  1. Strain – The strain you use will make a huge difference! Some strains make tons of trichomes and will give you good returns on rosin, so weed will make next to nothing.
  2. Pressure – The more pressure your Rosin Press can produce, the more rosin you’re likely to get.
  3. Grow Method (Lights) – Powerful grow lights are more likely to produce weed with lots of resin. So, good lights = more rosin!
  4. Heat – In short, less heat (down to 220°F) will produce a better product, but less yield. Higher temps will produce more rosin of lower quality.
  5. Moisture – Dry buds will soak up much more of your rosin before it can make it to your parchment paper. Buds at about 62%RH will work great.
  6. Age – Although we can’t say this definitively, our testing shows that newer bud seems to put out more rosin that older bud. This could be a side-effect of moisture, but again, we don’t have proof besides informal testing.

As a very rough estimate, you can expect about

  • 5-10% return from a hair straightener (in good scenarios)
  • 8-17% returned from a manual press
  • 20-25+% from a hydraulic press

Factors 2 and 4 are largely dependent on your rosin press. In general, you can expect the most rosin from a hydraulic press, a fair amount of rosin from a manual press, and the least from a hair straightener.

If you want a high-quality rosin press, be prepared to PAY!
(Note how the price jumps from $500 to $2000. Guess which ones are hydraulic…)

All 6 factors will drastically affect how much rosin you’re able to press out of your cannabis. When pressing your rosin, try testing out these factors individually. Not only will you have a good time producing rosin, but you’ll learn the best way for you to maximize the amount of rosin you get in while maintaining a level of quality you like.

How to Make Rosin with a Rosin Press

The MyPress Gen 2 Rosin Press – A midrange press that gets the job done

  • Easier method
  • More efficient; you’ll get more rosin per press
  • Fun! Making your own rosin is actually fun with a press!
  • Expensive. A decent press costs a pretty penny and higher-end presses can cost thousands!

You’ll want to thoroughly read the instructions for your Rosin Press before you use it. Although the instructions are simple, they can vary quite a bit depending who makes the press.

What You’ll Need:

  • Rosin Press
    • In this tutorial, I’ll be using the MyPress Gen 2, but there are higher grade (more expensive) ones like the Nugsmasher XP
  • Minimum 1g of weed (you’re going to want more, but only press 1g at a time unless your machine says otherwise)
  • Parchment paper (do not substitute with wax paper)
    • You can get squares or a roll
  • Pollen press (not absolutely necessary, but it helps)
  • Wax collecting tools
  • 25-micron press bags (for pressing hash/kief)

Making Rosin

  1. Plug in your Rosin Press and turn it on.
    • You’ll need to figure out what temperature works best for each strain, but 220°F is a good place to start.
  2. While your press heats up, grind up 1-1.5g of cannabis. You can also just use a whole nug to avoid wasting resin.
    • You can also press kief, dry-ice hash, or bubble hash.
  3. Use your pollen press to turn your weed or hash/kief into a thin disk.
  4. Make an envelope out of parchment paper for your weed.
  5. Place your weed at the back of the envelope.
    • If you’re using hash, place the disk in a 25-micron bag first to keep the hash from absorbing rosin.
    • Warning: the micron bag will absorb some of the rosin. It’s just the way it is.
  6. Open the heated plates of your press.
  7. Place the envelope on the bottom plate and then press your weed by closing the plates (consult your Rosin Press instructions)
  8. Leave the disk between the plates at 220°F for 60-90 seconds.
    • You’ll have to experiment to find the best heat/time combination for the strain you’re doing, but that’s part of the fun!
  9. Carefully open the plates (please don’t burn yourself) and remove the envelope
  10. Carefully open the envelope. Note the sticky substance all around your weed. That’s homemade rosin!
  11. Take out the used disk of weed without letting it touch the rosin and allow the rosin on the parchment paper to cool for about a minute.
  12. Use a scraping tool to collect your new rosin.
  13. (Optional) Press your weed once more to get all the rosin you can.

How to Make Rosin with a Hair Straightener (the low-budget method)

Kipozi makes a high-quality hair straightener that can also make rosin!

  • Dirt cheap compared to a Rosin Press. If you have a hair straightener or a very forgiving partner with a hair straightener, you already have most of what you need!
  • The act of pressing only takes about 20 seconds compared to a Rosin Press that takes 90 seconds.
  • The resulting product just isn’t as good.
  • Much more likely to burn yourself!
  • Little-to-no control over the level of heat. This can be fixed by using a high-quality straightener like this one.
  • Less efficient. You’ll actually get less rosin per press than if you had used a dedicated press.

What You’ll Need:

  • Hair Straightener
    • I used a hair straightener by Kipozi and honestly, I was surprised at the options it had and how well it performed.
  • At least 1g of weed (doing more than 1g at a time can be wasteful)
  • Parchment paper (do not substitute with wax paper)
    • You can get squares or a roll
  • Oven-safe gloves
  • Pollen press (not absolutely necessary, but it helps)
  • Wax collecting tools
  • 25-micron press bags (for pressing hash/kief)

A few rosin presses collect on a wax tool. Yummy!

Making Rosin

  1. Grind up 1g of cannabis or just use a whole (1g) nug if you’re feeling saucy.
    • You can also press kief, dry-ice hash, or bubble hash.
  2. Use your pollen press to turn your weed or hash/kief into a thin disk.
    • Again, you can also just use a whole nug to avoid wasting resin.
  3. Use your parchment paper to make an envelope for your weed.
  4. Place your weed at the back of the envelope.
    1. If you’re using hash, place the disk in a 25-micron bag first to keep the hash from mingling with the rosin.
    2. Warning: You will lose some rosin to the press bag. I know it hurts, but it’s normal.
  5. Plug in your hair straightener and turn it on. Make sure it’s on a surface that won’t be affected by the heat (like a kitchen counter).
    1. Turn it down to the lowest setting if you have the option. If your straightener has a temperature control like this one, set it to 220°F.
  6. Put on your oven-safe gloves while the hair straightener heats up.
  7. Place the envelope on the bottom heating element of the hair straightener plate and then close the straightener around your weed-envelope.
  8. Press down firmly on the hair straightener for 15-20 seconds. You should hear sizzling.
    • Seriously, press down hard!
  9. Remove the envelope from the hair straightener and put the straightener out of the way so you don’t accidentally burn yourself.
  10. Carefully open the envelope. Note the sticky substance all around your weed. That’s homemade rosin!
  11. Take out the used disk of weed without letting it touch the rosin and allow the rosin on the parchment paper to cool.
  12. Use a scraping tool to collect your new rosin.
  13. (Optional) Press your weed once more to get all the rosin you can.

Using and Storing Rosin

Now that you know how to make rosin, it’s important that you know what to do with it!


Rosin can be placed on top of flowers to make your bud stronger and tastier. It can also be used directly as a dab if you have a dab rig or a portable dab vaporizer/rig.


Firstly, you’re going to need containers to put your rosin in. Rosin is super-sticky (and some strains can be even stickier than others), so you’ll want a silicone container so your product is easier to handle.

There are the “standard” silicone containers you’ll see in dispensaries, and then there are cool wax containers like these if you prefer a little more flair.

Officially, it’s advised that rosin only is kept for around 3 days in regular conditions, or up to a week if stored inside an air-tight container in a refrigerator. The reasoning behind this schedule is that rosin will lose its distinctive flavor quickly, and keeping it for a short amount of time will prevent that from happening.

Just to be safe, this is a good rule to follow. It ensures that you don’t waste anything and that any rosin you make will be super-fresh. That being said…

Some growers just aren’t as concerned with flavor profiles. If your main concern is potency, you can probably keep your rosin for much longer without a noticeable drop in its apparent strength. I’ve stored rosin at room temperature in a non-airtight container for about 3 weeks and it felt just and powerful as the day I got it.

There you have it! Now get out there, make a bunch of tasty rosin and send us pictures to show how well it worked out for you!
