What is the Granddaddy Purple strain?

Granddaddy Purple, which is sometimes spelled as “Grand Daddy Purple” and is often referred to as “GDP” or “Granddaddy Purps,” and is a pure indica that was created by the Ken Estes’ San Francisco lab in Northern California. Known for being quite the potent strain, Granddaddy Purple is the offspring of parent strains Big Bud and Purple Urkle–both of which are indica-dominant hybrids.

As one of the most popular indicas in the State of California, Granddaddy Purple is often compared to another highly popular indica-dominant strain known as “Grape Ape.” However, its popularity isn’t relegated just to Californians, which is why so many growers flock to us at Growers Choice Seeds to buy their Granddaddy Purple feminized marijuana seeds to grow at home for medical and/or recreational purposes.

Packing quite the punch, novice users and those with a low tolerance to THC will definitely want to start off conservatively with maybe just one or two hits at most and wait to see how its potent effects land before indulging in more.

What are the effects of the Granddaddy Purple strain?

  • Relaxing
  • Uplifting
  • Unwinding
  • Euphoric

Known for its powerful cerebral effects and soothing physical reaction that is said to quickly eradicate stress, Granddaddy Purple is about calming both mind and body whilst leaving recreational users happily floating in a warm fuzzy blanket of good feelings before drifting off to the land of dreams.

However, before Granddaddy Purple has you blissfully sawing logs, you’re likely to first experience a strong and uplifting mental high that will probably impart some potent psychoactive effects that, depending on your tolerance level, could either result in a nice humming and euphoric brain buzz or leave you feeling a bit overwhelmed. Used in moderation though, chances are you’ll just be able to enjoy the happiness and sense of contentment you start to feel as this indica’s cerebral effects wash over you. Even though this strain is heavy on the relaxing effects, many say that the mood boost it provides tends to leave them initially feeling filled with so much joy that they cannot help but burst out into laughter.

All that said, don’t let Granddaddy Purple’s initial effects fool you into thinking that this is a strain for hitting the town with, as sedation is nearly guaranteed with this powerhouse of an indica. It is considered by more seasoned users to be an ideal choice for ending the day with a sense of serenity and joy. As such, Granddaddy Purple and its powerful effects may be the solution to unwinding from a long and stress-filled day that has you feeling mentally and physically tensed up, as once its physical effects take hold, users tend to report feeling a deep sense of relaxation and, sometimes, a little bit peckish before merrily toddling off to bed.

What are the potential therapeutic benefits of the Granddaddy Purple strain?

While Granddaddy Purple doesn’t contain a significant amount of CBD, that doesn’t mean that it lacks the potential to serve as an aid to medical marijuana users. At the same time, you must remember that the purported ability of any marijuana strain, including Granddaddy Purple, to address a medical condition is purely anecdotal and is not to be understood as a serious medical claim of guaranteed efficacy.

As such, many medicinal users have reported that using Granddaddy Purple has helped them to manage issues like stress, feelings of anxiousness, mood swings, worried thinking, and feelings of being down in the dumps–all thanks to how it both elates and calms the mind.

In terms of physical pain, this indica is often said by those in the medical marijuana community to possess the potential to alleviate chronic pain symptoms, muscle spasms, nausea, and appetite loss–the latter two of which, anecdotal evidence from some research suggests may be especially beneficial to patients undergoing chemotherapy and/or radiation. Lastly, the strong physical relaxation that Granddaddy Purple tends to induce will likely be of great help to those who struggle with being able to fall and/or stay asleep.

What are the adverse effects of the Granddaddy Purple cannabis strain?

As mentioned at the start, this popular cannabis strain is one power-filled indica, which means that inexperienced users should start out slowly so as not to be overcome by its potential side effects of dizziness, an unlikely but possible increase in already-existing paranoia levels, and maybe even a minor headache that does not quickly dissipate.

Other than that, Granddaddy Purple’s most common adverse effects are the ones common to most all cannabis strains–dry, itchy eyes and cottonmouth. Fortunately, these two are easily addressed by staying hydrated and drinking plenty of water.

What are Granddaddy Purple’s fragrance and flavor profiles?

Before getting into Granddaddy Purple’s flavor and aromatic profiles, let’s first provide you with the terpenes that are responsible for its delightful aroma and taste.

Granddaddy Purple’s Terpenes

Terpenes, which are naturally occurring chemical compounds found in plant life, and even some animals, are responsible for the fragrance, flavors, and sometimes even the coloration of all kinds of vegetative forms, including marijuana plants.

When it comes to Granddaddy Purple’s terpenes, it contains linalool, myrcene, β-Pinene, caryophyllene, geraniol, and α-Bisabolol.

The Aroma and Taste of Granddaddy Purple

Granddaddy Purple is known for its tempting berry aroma profile that many users say smells of grapes and berries. Its sweet aroma is likely to linger in the room long after you’ve finished enjoying this indica.

As for its taste, Granddaddy Purple tastes very similar to its fragrance, offering users a tasty fruity flavor of grapes and berries but with an added hint of pine and citrus.

How do I grow Granddaddy Purple cannabis seeds?

Not only is Granddaddy Purple a popular choice amongst recreational and medical users for its uplifting and sedative effects, but it’s also a fan favorite amongst cultivators thanks to its ease of growth, which is due in part to its naturally high resistance to common diseases. In addition, since we at Growers Choice Seeds only sell feminized seeds growers have a near-100% likelihood of ending up with all-female plants.

While Granddaddy Purple plants can definitely be grown outdoors in a moderately warm climate where they get plenty of sun, as well as protection from the elements, it tends to thrive best indoors. However, if you are going to cultivate this one outside, you’ll want to keep an eye on it as around day 60 its hefty buds may start to weigh down its limbs and branches, at which point you will want to provide them some additional supports.

To cultivate this fabulous marijuana strain inside, know that it will respond well to both hydroponics and soil so long as it is in a well-ventilated space. In addition, it prefers temperatures in the 70s (Fahrenheit) and humidity levels that are in the 50-55% range.

What do Granddaddy Purple cannabis plants look like?

Granddaddy Purple tends to produce bushy plants that are short and stocky with very dense buds–all of which are common indica structural traits. However, its nuggets are quite large, which is generally more of a sativa trait. For the curious, it is believed that Granddaddy’s Purple has such large buds thanks to its parent Big Bud.

Speaking of this indica’s nuggets, which feature vibrant orange pistils and a very generous frosty layer of white trichomes, word on the street is that they get their deep purple hues from their other parent Purple Urkle.

When is the harvest time for your Granddaddy Purple cannabis plants?

When it comes to yields both indoors and out, Granddaddy Purple does not disappoint. However, while most strains, like indica-dominant GMO Cookies and indica-leaning THC Bomb, produce larger outdoor yields than indoor ones, Granddaddy Purple tends to provide indoor cultivators with slightly larger harvests.

When grown inside, this indica should render approximately 540 grams per square meter after completing its flowering time in 8 to 11 weeks.

Although Granddaddy Purple does produce bigger yields indoors, its outdoor harvests aren’t exactly disappointing as they tend to average around 480+ grams per plant sometime around the middle of October.

    Excellent choice if you like purple weed and a moderate challenge in the garden. Purchased 10 seeds online and they were FAST to ship to my apartment! I was honestly amazed! The seeds took about 1 week to germinate and popped right out of the ground with a little purple crown that grew taller than me over the course of 3 months! Awesome choice, very fresh!

    Granddaddy Purple is the ultimate insomniac strain. It melts away pain and stress while leaving you feeling euphoric and relaxed. It’s a go-to for those who need a heavy indica to help them sleep. The taste is like a sweet grape candy and the high is long-lasting. Highly recommend for nighttime use.

    Very high THC percentages on Granddaddy will have you flying fast and cruising right into bed. Growing this was easy outdoors, this seed was quite forgiving with its conditions and rewarded me with a great amount of weed. Absolutely perfect!

    Great for smoking with your homies on a Friday night. It kills stress but keeps you chatty….the perfect combo for someone with social anxiety (aka me lol).

  11. Verified Owner

    These nugs do NOT disappoint. I was able to harvest flower clusters the size of my hand, and sometimes even bigger. The yields were impressive! I measured out about 100 or so grams per plant, and around 500 G in total (across 5 plants).

    GDP is a sweet, deeply soothing indica that helps with stress and anxiety. It’s been a great experience working with MJ again, feels like it has been so long. I am very excited for this upcoming growing season. My skills are sharper than ever!

    Another excellent cultivar that really seems to enjoy and tolerate the summer heat. Much like the Blackberry Kush review I left. Beautiful green foliage, but a slow starter. This particular cultivar was planted directly into the garden with only a small addition of any amendments to the soil. Impressive nonetheless and recommended! Easy to grow and clone.

  22. Verified Owner

    Granddaddy purple, or GDP as my friends and I call it, is really something special. Gotta have this weed in my life. It’s so dang tasty and helps a lot with stress and anxiety. I promis you, you will enjoy this weed, even the growing process is fun! I got nearly 600 Grams from 3 plants, that’s nearly 200 G per plant!! Always quality products from GCS!

  23. Verified Owner

    These fat purple nugs aren’t gonna grow themselves! Get your dang butt over to the checkout line and BUY these weed seeds! Online is the way to go, SO much more convenient and fast! Plus the seeds are great, maybe a little small?

  24. Verified Owner

    This purple weed is so bright it almost hurt my eyes! Buying online is the ONLY way to go, especially if you’re living in a rural community without consistent access to marijuana! It’s as convenient as can be, they ship anywhere in the US and Canada! You can also expect a pretty nice looking yield friends 🙂

    23% THC is nothing to joke about. This stuff hits hard and FAST and is mostly best for experienced smokers and growers. The purple nugs are light and fluffy, pack very well into a bong or a joint. Excellent marijuana for the masses.

    After a long hike in the mountains, I really look forward to smoking the granddaddy purple at the trailhead. It’s my way of telling myself “job well done.” Had 5 seeds delivered after ordering them online. I am a total outdoors person so I loved working with these plants, they made good summer companions, along with my doggo.

  27. Verified Owner

    So purple you’ll probably look twice. It’s a berry-flavored weed, perfect on the weekends or after work. I used to come home to my plant every evening, I prune and water it like crazy. 6 months go by and I am swimming in purple flower. Never thought it was possible.

  28. Verified Owner

    One of the few strains that thrives outdoors better than indoors. Lucky that I live in SoCal, literally the perfect growing conditions for all kinds of weed. I really like the taste, the smell, and the vibezzzz. The fat purple nugs are exciting, they are like “special” haha. I feel like a true weed wizard when I grow this strain.

  29. Verified Owner

    Grandaddy purple is an OG west coast strain started here in SF, and I am proud to grow it right here where it originated. Best looking grow I have had so far, it’s a very robust plant with a lot of cRAYYYYYYY looking flower, that’s so sticky and tight and just plain NAST. Do a kickflip BRUH!

  30. Verified Owner

    Shipping was fast and germinated nicely. They are growing nicely and I’m very happy so far. I’ll add another review after harvest. Great company!!!
