The Grease Monkey strain is a potent indica dominant hybrid strain with average THC levels between 22-28%. First developed by Exotic Genetix, a cannabis breeder based in Tacoma, Washington, Grease Monkey is a cross between indica Gorilla Glue #4 and their hybrid house strain Cookies and Cream.

Besides its high potency, Gorilla Glue is known for its highly gassy aroma, and sweet diesel flavor. It has dense, attractive buds that smoke well with little harshness. 

Grease Monkey provides classic indica effects like relaxation, increased appetite, and sedation. It is a great strain for relaxing in the evening, relieving pain or anxiety, or preparing for sleep.

Where Does Grease Monkey Come From?

Grease Monkey was first produced by cannabis breeding company Exotic Genetix in Tacoma, Washington. The strain is a cross between Gorilla Glue #4 and Cookies and Cream and combines many of the well liked properties of both parents. 

When Did Grease Monkey Come Out?

Exotic Genetix has been offering the original Grease Monkey strain since the mid 2010s, and have since moved on to breeding Grease Monkey to other strains. Lemon Drop, Slippery Susan, and Funky Charms are a few of the strains created with Grease Monkey as the mother. 

In the past year or so, they have also released the series “Grease Monkey Volume 2” which contains the strains Truffle Monkey, Tarts, Sweat Helmet, and Carmelita. Unlike previous hybrids, these strains use pollen from Grease Monkey to fertilize a different cannabis plant.

What Does Grease Monkey Look Like?

Grease monkey produces very dense, small buds, with a forest green base color streaked with purple. The buds are heavily frosted with white trichomes and bright orange hairs. The overall look is highly colorful and great for display, with moderate stickiness when handled.

What Does Grease Monkey Taste Like?

Similar to its parent Cookies and Cream, Grease Monkey leaves a lingering sweet flavor in the mouth after smoking, while its second parent Gorilla Glue #4 adds a pungent, gassy taste. Grease monkey has a complex flavor profile overall with flavor notes of gasoline and vanilla. 

The strain tends to be smooth, and does not usually cause much coughing or discomfort when smoked.

What Does Grease Monkey Smell Like?

Grease Monkey is highly aromatic with an earthy and pungent smell that makes smoking the strain discreetly difficult. Ideal for enjoyers of gassy weed, this strain releases a strong yet balanced smell that combines sweet fruits and diesel. 

Is Grease Monkey an Indica or Sativa?

Grease Monkey is considered an Indica dominant hybrid, with about 70% indica genetics and 30% sativa genetics. Its parents were Gorilla Glue #4, an indica, and Cookies and Cream, a balanced hybrid. 

This strain boasts many typical Indica effects, including full body relaxation, increased appetite, and light sedation. 

How Strong is Grease Monkey?

Grease Monkey is quite strong, and often produces couch lock or intense munchies in even veteran smokers. The strain is a great choice for those looking for potent relaxing or sedating properties, but may be uncomfortably strong for novice smokers. 

How Much THC in Grease Monkey?

Grease Monkey is considered a potent strain, with THC levels typically falling between 22-28%, although some batches have been reported to contain 30% or higher THC levels. 

This makes Grease Monkey stronger than both of its parents, Gorilla glue #4 and Cookies and Cream. Although potent in their own right, these two strains typically have slightly lower THC values in the low to mid 20s.

How Much CBD in Grease Monkey?

Grease Monkey is a low CBD Strain, with values for CBD and CBG both typically testing between 0.4-0.8%. This strain is not an ideal choice for those looking for a CBD heavy experience. Being a relatively new strain, Grease Monkey does not have any high CBD variants on the market at this time.

What Effects Does Grease Monkey Have?

Grease Monkey produces many of the classic effects of a strong indica, including bodily relaxation and euphoria that eventually give way to feelings of heaviness and sedation. This is a great after work strain for relaxing and preparing for sleep. 

Because of its potency, Grease Monkey does cause some side effects, especially in users with a lower THC tolerance. These can include anxiety, munchies/ food cravings, dry eyes and mouth, and dizziness. The sedating effects of this strain can also be problematic if you need to stay awake and alert for something later in the day.

What Conditions is Grease Monkey Good For?

Grease Monkey has strong pain relieving properties, and is often used to relieve chronic pain, inflammation, or headaches. Its sedative effects also make it a great choice for those who struggle with insomnia. Finally, Grease Monkey is a strong appetite stimulant and can be a great choice for those who struggle with lack of appetite, nausea, or indigestion.

Some people also use this strain to calm their anxiety, since it can be very relaxing to smoke. However, inexperienced users with anxiety may wish to stay away from this strain, as smoking high THC buds when you have a low tolerance may actually increase feelings of anxiety.

What is the Flowering Time of Grease Monkey?

Grease Monkey has a relatively short flowering time of 8-9 weeks when grown indoors. In order to mature, Grease Monkey needs bright lights and relatively hot temperatures in the upper 70s or lower 80s. Additionally, a strong filter on your exhaust fan is essential due to the strong smell of these plants when grown indoors, especially once they begin flowering.

How Tall Does Grease Monkey Grow?

Although Grease Monkey has predominantly indica genetics, its growth habits are more similar to a sativa. Grease Monkey can grow between 30-80 inches tall with a dense and bushy growth habit. Although its natural resistance to many diseases makes it relatively easy to grow indoors, Grease Monkey needs regular pruning and trimming of the lower fan leaves to keep its size in check. 

When to Harvest Grease Monkey?

First, wait until after the stated flowering time of 8-9 weeks. Then use a handheld magnifying glass to inspect the trichomes on the buds. The buds are ready for harvest when the trichomes are 50% milky white and 50% amber. If the trichomes are clear and not sticky, they are not yet ripe. 

For lighter, more energetic effects, the buds can be harvested earlier, when there are a lower percentage of amber trichomes. For heavier, more sedating effects, harvest a little later.

How Much Does Grease Monkey Yield?

When grown indoors, Grease Monkey can be expected to yield about 18 ounces of bud per square meter of floor space. After drying and curing, your buds will lose between 40-60% of their weight in evaporated water, leaving you with about 7-10 ounces of finished product per square meter. 


Grease monkey is a highly potent indica dominant hybrid, with about 70% indica genetics to 30% sativa genetics. With average THC levels of around 22-28% or higher, this strain delivers a strong high best suited for more experienced smokers.

Grease Monkey has dense, forest green buds with heavy frosting of white trichomes and bright orange hairs. The smell and flavor is highly pungent and earthy, with notes of sweet vanilla and diesel. The strong aroma is well liked by fanciers of gassy weed, but may be a poor choice for those looking to smoke discreetly. 

The effects of Grease Monkey are in line with other indica dominant strains. The high begins with bodily relaxation and euphoria before progressing to increased appetite and sedation. Medical users prefer this strain for relieving chronic pain and inflammation, insomnia, lack of appetite, and nausea. 

Although the effects of Grease Monkey are generally positive, the high may be anxiety inducing for those with a low THC tolerance. Other side effects may include dry eyes and mouth, dizziness, and excessive tiredness or hunger.

Grease Monkey is relatively fast growing and resistant to many common pests and fungal infections. However, it grows very large for an indica and needs a good amount of trimming and training to fit well in an indoor grow. Growers can expect up to 18 ounces of fresh buds at harvest time.
