Discover the MAC Stomper Strain (MAC X Grape Stomper OG)

The MAC Stomper strain is Capulator’s cross of MAC and Grape Stomper OG: the frost and creamy citrus of Miracle Alien Cookies paired with a classic grape and fuel line.

I’m James Bean, founder of Seeds Here Now since 2010. This MAC Stomper strain review covers the lineage, the breeder, the aroma and look, reported potency, and how it compares with other MAC and Grape Stomper strains.

MAC Stomper at a Glance

Lab figures vary by sample, so treat THC numbers as reported ranges, not guarantees. We describe lineage, aroma and appearance only; we make no claims about effects.

MAC Stomper Genetics and History

The MAC Stomper strain comes from Capulator, the California breeder best known for creating MAC, short for Miracle Alien Cookies. With MAC Stomper, Capulator paired its signature line with Grape Stomper OG to add grape and fuel to MAC’s creamy citrus base.

MAC is listed as Alien Cookies x (Colombian x Starfighter). It became one of the most collected strains of the past decade, famous for heavy frost, a creamy sour citrus nose and a striking look. Read our MAC 1 strain review for the full story on that parent.

Grape Stomper OG is the grape side of the cross. The original Grape Stomper line is commonly credited to Gage Green Genetics and listed as Purple Elephant x Chemdawg Sour Diesel, and Grape Stomper OG adds an OG parent on top. Our earlier review listed that OG parent as Underdawg OG, while some databases list it more generally as OG, so we treat the exact OG cut as reported rather than confirmed. Read our Grape Stomper strain review for more on that family.

Together, the parents give MAC Stomper seeds a pedigree that reaches into Cookies, Colombian sativa, Chemdawg and OG genetics, which is a lot of history for a single pack.

MAC Stomper Aroma and Appearance

The MAC Stomper strain blends sweet berry and grape with diesel and earth. Many descriptions also mention citrus and a light spice that add depth, a sign of the MAC parent’s sour citrus side.

Flavor notes usually land on sweet and sour grape with earthy pine and a hint of spice. The grape and fuel come mostly from Grape Stomper OG, while the creamy, citrus lift points back to MAC. Aroma always varies from one sample to the next, so treat these notes as a general guide.

Visually, MAC Stomper is a standout. Buds are dense and resinous, with green and purple coloring set off by bright orange pistils, and the heavy frost that MAC is known for. To learn more about that frost, read our guide to what cannabis trichomes are, and for the smells, our guide to what terpenes are and why they matter.

About Capulator, the Breeder Behind MAC Stomper

Capulator is a California breeder whose name is tied to MAC. After MAC became a phenomenon, Capulator built a catalog that uses MAC and other house selections as building blocks, which is why so many Capulator lines share that frosty, creamy citrus signature.

The catalog goes well beyond MAC crosses. Chem Chillz pairs GMO with Chillz, and Miracle Grow combines Scott’s OG and Blockhead genetics. Little Tokyo and Big Chillz round out a lineup that leans on fuel, cream and frost.

Capulator shares its work at thecapulator.com and on Instagram at @capulator. Browse the Capulator catalog at Seeds Here Now, including Chem Chillz, Miracle Grow and Little Tokyo. Individual lines rotate, so some may be between restocks.

The Story of MAC, MAC Stomper’s Famous Parent

MAC started as a Capulator selection from Alien Cookies crossed with a Colombian x Starfighter line. It earned the name Miracle Alien Cookies, and the first well-known cut, MAC 1, spread quickly through California and then across the country.

Breeders love MAC because it passes on frost, color and a distinctive sour cream and citrus nose. That makes it a common parent, and it explains why the MAC Stomper strain carries so much bag appeal even with a grape-forward partner.

For buyers, MAC crosses from Capulator itself carry extra weight, because they come from the breeder who made the original.

The Grape Stomper Side of the Family

Grape Stomper is one of the classic grape strains. Its commonly listed parents, Purple Elephant and Chemdawg Sour Diesel, explain the mix of sweet grape and sharp fuel that runs through every Grape Stomper descendant.

Grape Stomper OG adds an OG parent to that base, bringing earthy pine and more gas. When that line meets MAC, the result is the grape, berry and diesel profile that defines the MAC Stomper strain.

What the MAC Stomper Name Tells You

Like many modern strains, MAC Stomper is named for its parents. MAC comes from Miracle Alien Cookies, and Stomper comes from Grape Stomper OG. Reading the name that way is a quick shortcut to the lineage before you even turn the pack over.

That naming habit runs through the whole family. Grape Stomper itself has been crossed into many lines that keep the Stomper name, and MAC appears in a long list of crosses that keep the MAC name. When a strain carries both, it usually means a breeder joined those two families on purpose.

The name also hints at the profile. MAC suggests frost, cream and citrus, and Stomper suggests grape and fuel. The MAC Stomper strain delivers both halves, which is part of why the name stuck.

MAC Stomper vs. Other MAC Crosses

Many MAC crosses pair it with dessert or candy partners, which pushes the result toward cream and sweetness. MAC Stomper takes a different route. By using a grape and fuel parent, Capulator kept MAC’s frost and citrus but added a darker, gassier layer underneath.

That makes MAC Stomper a useful comparison piece in a MAC collection. Set it next to MAC 1 and you can see how much one partner changes the nose, the color and the overall character of the line.

Grape strain buyers and MAC buyers both have a reason to want MAC Stomper seeds, which is not true of every MAC cross.

Why People Pick the MAC Stomper Strain

Three things set MAC Stomper apart. First, it comes straight from the breeder who created MAC. Second, it pairs MAC’s cream and citrus with a classic grape and fuel line, a combination that is less common than the many MAC x dessert crosses on the market. Third, its green and purple coloring with bright orange pistils makes it one of the more striking MAC crosses to look at.

How to Grow the MAC Stomper Strain: Tips and Tricks

Are you ready to grow MAC Stomper like a pro? We’ve got you covered with expert tips and tricks to ensure your cultivation process is successful.

First and foremost, it’s important to note that MAC Stomper is a relatively easy strain to grow, making it a great choice for novices and experienced cultivators alike.

When it comes to germination, we recommend using the paper towel method. Simply place your seeds in between two damp paper towels and store them in a warm, dark place. Once they sprout, plant them in their final grow container, preferably a five-gallon pot.

MAC Stomper thrives in a warm and humid environment. Keep the temperature between 70 and 85 degrees Fahrenheit and the humidity between 50 percent and 70 percent. Make sure to provide good air circulation with fans and avoid overwatering, as MAC Stomper prefers soil that is slightly dry.

During the vegetative stage, MAC Stomper responds well to frequent feedings. We recommend using a high-quality nutrient mix with an NPK ratio of 3-1-2. Once it moves into the flowering stage, switch to a nutrient mix with a higher level of phosphorus and a lower level of nitrogen.

MAC Stomper has a flowering time of 8 to 10 weeks and yields an average of 400-500 grams per square meter. Keep a close eye on the trichome development, and harvest when they turn cloudy and amber in color for a high THC content.

Now that you know the basics of growing MAC Stomper, it’s time to put your skills to the test. Happy growing!
