Curated: 11 of the Best Weed Strains to Grow for Rosin

When it comes to Cannabis preparation, making solventless hash oil (also known as rosin) is one of the best ways to get the most out of your weed. Read below to learn how we ranked and recommend the best strains for rosin.

Rosin contains higher amounts of THC compared to other types of cannabis preparation. In fact, the best rosin outclasses any type of cannabis product in terms of delivering strong effects. There are also therapeutic benefits that help with pain relief and nausea.

What is rosin?

Rosin is different from extracts like shatter or other concentrates such as wax. One main difference is how it is made. Making rosin doesn’t require chemicals because the main technique to produce rosin involves only heat and pressure, making it one of the best natural (not to mention safe) methods of making cannabis concentrates.

Rosin also doesn’t require you to separate the trichomes from your buds. If anything, rosin uses all of the buds – although you can still make rosin from kief or hash. You would want to use buds specifically because rosin made from buds has a more pronounced flavor than kief or hash.

As for how you make rosin, the simplest method is using a hair straightener, it provides the necessary heat and pressure to squeeze out the rosin from your buds. You would also need parchment baking paper to prevent the gooey hash oil from sticking to the hair straightener. You can also try dry sifting and bubble hash to make concentrates. Dry sifting and bubble hash are methods to separate the trichomes from your buds.

The difference between the two is in the process of separating the trichomes. Dry sifting is an efficient and simple method using only a fine screen.  On the other hand, Bubble hash requires more work as you need to submerge and shake your cannabis in ice water to remove the trichomes from the plant. Additionally, you would need multiple filter bags to get the most hash from the process.

What is the worst cannabis strain for pressing rosin?

The worst type of strain you can press for rosin is those with low amounts of trichomes. Typically, the best strains for hash rosin are indicas since they produce more trichomes than sativas.

Can I press any strain of cannabis for rosin?

Yes, however, your yield will vary depending on your strain. It’s important to consider these three factors when choosing a strain for rosin production: potency, flavor, and resin.

What to look for in a rosin strain

For the highest quality rosin, you need to start with the highest quality marijuana strains. There are a couple of things you can keep in mind to ensure you end up with a solid end product that'll keep your head spinning for days. If you so choose, of course, we're not here to judge. Let's dive in.

Potency

To get the most concentrates from your buds, you need the best strains for rosin production. One trait to look out for is potency. Although rosin already has a high THC content of 75% to 85%, there’s nothing wrong with choosing strains that also pack a punch.  Doing so ensures that the concentrates are potent enough to your liking.

Flavor

Rosin is known to be one of the more flavorful concentrates out there despite the process involved in making the gooey hash oil. There’s still plenty of flavor left over to enjoy, so choose a strain with your preferred flavor profile. Additionally, use freshly harvested buds for the best results.

Resin

Resin and rosin might sound similar, but they are actually two different things. While rosin is what you get from putting your Cannabis buds through a lot of heat and pressure, resin is simply the substance that Cannabis naturally produces and stores in its trichome. Resin also refers to the active compounds such as THC that give cannabis its effects.

The 11 best strains to grow for rosin weed

When it comes to making concentrates, the method you use to separate the trichomes from your buds can affect your overall rosin yields. Some strains yield more through dry sifting, while others work better with bubble hash. There are even strains that are good all around. It’s important to consider this when looking for the highest-yielding rosin strains.

White Widow is a favorite strain because of its high THC content that works right away, giving you a steady cerebral head high while also providing a relaxing buzz.  It’s also one of the best strains for rosin since the buds it produces are sticky, meaning it’s high in resin content.

If you want to have an easy time growing White Widow, you can choose our autoflowering variant, which reduces the grow time and the difficulty of growing this strain.

If you’re looking for a strain with an intense flavor profile and high THC content, try Wedding Cake. This sweet strain will hit you with its strong flavor and scent of vanilla with a hint of cherry pie while leaving you uplifted and relaxed. Besides its taste and effects, Wedding Cake is one of the top strains of pressing rosin because of its high concentration of trichomes.

Although it’s already easy to grow, an autoflowering variant of Wedding Cake will help growers cultivate weed discreetly since Wedding Cake Autoflower produces much smaller plants.

Sour Diesel is a potent strain that combines intense flavors with high resin content, making it one of the best strains for rosin. The high levels of THC of this strain give Sour Diesel its mood-boosting and energizing effects. Its flavors also match these effects, as you’re left tasting lemon and diesel.

Sour Diesel is known for how difficult it is to cultivate, so we offer a much easier alternative: Sour Diesel Autoflower.

Do-Si-Dos is a hybrid strain known for its flavor and potency, but many people seem to forget that it’s also high in resin content.

It is one of the best strains for concentrates because not only do its buds produce a lot of resin, but it’s also high in THC, which, when consumed, will leave you feeling uplifted and euphoric.

There’s nothing quite like Girl Scout Cookies Extreme regarding potent and resinous strains. Despite its friendly name, this strain packs quite the punch, leaving you feeling relaxed and happy.

Part of what makes GSC Extreme a potent strain is not just its high THC level but also its high resin content.

Gorilla Glue (GG4) is a Cannabis strain that produces plants with high resin content. Its sticky buds are known and loved by many cannabis connoisseurs, both for their deeply relaxing effects and complex flavor profile.

Moreover, Gorilla Glue’s super sticky buds make some of the best rosin if you don’t lose most of it on your fingers. If you’re looking to grow Gorilla Glue but don’t have the space for its tall plants, you can choose to grow Gorilla Glue Autoflower instead.

Known for its high THC content, OG Kush is a natural pick if you’re looking for the best flower for rosin making. Its full-body high will hit you with a strong feeling of euphoria while also helping you unwind.

Additionally, OG Kush produces highly resinous flowers, which means you need to be careful not to get any of it stuck on your fingers once you’re harvesting its buds.

Although it is a moderately difficult strain to grow, it does have an autoflowering variant that helps new growers experience OG Kush for themselves.

Sunset Sherbet is an indica-dominant strain that’s both potent and flavorful. Its high THC levels provide a long-lasting feeling of euphoria that will leave you calm and relaxed. Its sweet flavors with a hint of mint only add to its sedative qualities.

Gelato is one of the best strains for hash rosin because of its high THC content that will first leave you feeling euphoric before hitting you with a piercing physical relaxation.

Outside of its potent effects, Gelato’s flavor is also recognizable. Like Girl Scout Cookies, this potent strain has a sweet taste with a hint of mint.

Tropicana Cookies is a resin-heavy strain that produces flavorful buds that have a fruity taste with hints of baked cookies. And despite having resinous buds, it provides a balanced high that energizes your mind and fills you with euphoria.

Although it may not have the same potent effects as other strains, its flavor and resin content are noteworthy enough to warrant its place as one of the best strains for bubble hash.

Chemdawg is a potent strain known for its head high that gives way to a strong yet soothing relaxation experience. Its sedative properties are enhanced by the additional touches of euphoria and happiness that you get from each puff. Outside of its potent effects, Chemdawg is also known for its strong diesel-like flavor with a lemon-pine aftertaste.

Other options for making hash and concentrate

When it comes to making extracts and concentrates, there are other methods. One of these methods is solvent extraction, which involves heat, pressure, and a hydrocarbon solvent. The main concern with making this type of extract is the risk. The process itself is dangerous, and it’s also illegal in some states.

However, hydrocarbon extraction produces more products than all other options regarding hash rosin yields. It’s also a much more effective process for a more potent product. Another method for making concentrates is a fine screen or herb grinder. This method produces kief, one of the few types of concentrates that new growers can make for themselves. It doesn’t require any chemicals, heat, or pressure.

Remember, solventless extraction is the best option if you’re looking for a safe way to make the gooey full-melt results that you get from hydrocarbon extraction. This method requires only heat and pressure, which you can easily produce with a hair straightener. Additionally, the solventless process preserves your buds’ flavor and smell,  which methods like hydrocarbon extraction usually lose.

The process of making solventless hash oil is safe as it is easy. You only need to press your freshly harvested buds between the hair straightener, making sure to use parchment baking paper to keep your rosin extractors clean and free from resin.
