Top 5 Best Purple Weed Strains

Many of us have only seen purple cannabis plants in pictures, admiring their striking lavender hues and wondering how to get some for ourselves. The science behind their vibrant appearance is fascinating.

One method to achieve purple marijuana applies to almost any cannabis variety: by lowering the nighttime temperatures in the grow room to create a consistent 15 °C (27 °F) difference with daytime temperatures once flowering begins.

This cool night air triggers the leaves to change color, much like autumn leaves. For more details, check out our guide on how to grow purple weed.

Alternatively, you can choose specific cannabis strains bred for their violet coloration. With the right varieties, growers can enjoy vibrant purple plants without needing to adjust temperatures.

Read on to explore the best purple strains of weed and learn how enjoyable it can be to cultivate a colorful tent full of potent purple pot.

1. Granddaddy Purple Feminized & Autoflower

The best purple weed strain ever created is Grandaddy Purple (GDP), an Indica-dominant hybrid developed in the California Bay Area in the early 2000s. 

A genetic cross between Purple Urkle and Big Bud, GDP is prized for its potent, flavorful, and generous yields, showcasing a striking purple hue.

Known for its complex flavors, Grandaddy Purple offers a juicy blend of sweet berries, citrus, and earthy pine notes, with THC levels reaching up to 23%. Users report full-bodied relaxation, calmness, happiness, and euphoria.

GDP can be grown indoors, outdoors, or in greenhouses, but it prefers consistent humidity around 50% and good ventilation, making it ideal for indoor setups.

This strain is also beginner-friendly, with mold resistance and a manageable height of about 100 cm. Flowering typically occurs in 9 to 10 weeks, yielding up to 500 grams per square meter.

Starting with Grandaddy Purple feminized seeds ensures a girls-only grow, while autoflower seeds simplify the process by removing the need to adjust lighting.

In just weeks, you'll enjoy the great taste and powerful relaxation that Grandaddy Purple brings.

2. Purple Kush Feminized

Another stunning violet variety is Purple Kush, a pure Indica that originated from Hindu Kush and Purple Afghani parents in the early 2000s in Oakland, California. 

Known for its impressive THC levels of up to 27%, Purple Kush offers full-bodied relaxation that can lead to couch lock, along with appetite stimulation and restful sleep.

Purple Kush feminized seeds produce plants that reflect their vibrant appearance, featuring flavors of spicy grape and sweet fruit. This strain grows into a squat, bushy plant, typically around 80 cm tall indoors, and is just as compact outdoors.

With high fungal resistance, it’s an excellent choice for beginners, ensuring a girls-only grow room.

With proper care, growers can expect a quick bloom time of 7 to 8 weeks, yielding fat buds with a harvest of up to 500 grams per square meter.

Purple Kush is not only colorful with its glowing purples and oranges but also one of the easiest strains to cultivate indoors, making it a top choice in the Weedseedsexpress collection.

3. Purple Punch Feminized & Autoflower

Purple Punch is a relatively new strain, developed in 2013 by crossing two Indica heavyweights: Larry OG and Grandaddy Purple. This 80/20 Indica-dominant hybrid has quickly gained popularity among breeders for its premium genetics.

With THC levels reaching up to 20%, Purple Punch provides deep relaxation and euphoric effects that often lead to a tranquil sleepiness. Its aroma resembles freshly baked blueberry muffins, complemented by sweet fruity flavors.

While Purple Punch feminized seeds are sometimes recommended for experienced growers due to its specific climate needs and susceptibility to pests, it thrives best in indoor environments.

This strain is short with strong lateral branches, making training easy. Flowering typically takes 8 to 10 weeks, yielding impressive indoor harvests of up to 650 grams per square meter.

Starting with Purple Punch feminized seeds ensures an all-female grow, while autoflower seeds offer a quicker harvest without light setup concerns. Either way, you'll soon enjoy a bounty of tasty, potent purple weed.

4. Purple Urkle Feminized

Purple Urkle is a classic California strain that originated in Humboldt County in the 1980s. This 80/20 Indica-leaning hybrid is a descendant of the original purple weed strain, Mendocino Purps, and is ideal for nighttime use.

Purple Urkle is known for its happy and calming effects, starting with a burst of creativity that transitions into full-body relaxation. With THC levels reaching up to 20%, it’s a popular choice for unwinding after a long day.

The strain boasts breathtaking flavors and aromas reminiscent of tropical fruits and sweet grapes. Best suited for indoor grows, Purple Urkle's structure is perfect for ScrOG training, and heavy pruning is recommended for better ventilation.

With proper care, feminized seeds will flower in seven to eight weeks, yielding up to 450 grams per square meter of sticky purple buds.

Consistently rated among the best purple weed strains, Purple Urkle’s genetics are in high demand.

Notably, its namesake, actor Jaleel White, known for his role as Steve Urkel on Family Matters, has launched a new line of cannabis varieties based on Purple Urkle.

5. CBD Purple Kush Autoflower

For an easy-to-grow, high-CBD, low-THC strain, look no further than CBD Purple Kush autoflower seeds available at Weedseedsexpress.

This Indica-dominant strain is a descendant of Purple Kush CBD and Purple Afghan CBD, with some Cannabis ruderalis genetics to enable autoflowering.

With CBD levels as high as 19% and THC under 1%, CBD Purple Kush autoflower provides deep physical relaxation without psychoactive effects. Users enjoy sweet fruity flavors with hints of berries and citrus, typical of the best purple strains.

This strain is perfect for indoor growing, as it has high resistance to fungus, mold, and pests, making it ideal for beginners.

For optimal CBD concentration, growers should allow a full eight weeks of bloom before harvest, resulting in a heavy yield of potent purple CBD flowers.
