Did you know that the Granddaddy Purple strain is considered legendary by many people in the cannabis community?

Let’s find out more about the benefits you’ll get when you grow or use it in our Granddaddy Purple strain review.

Granddaddy Purple strain (aka GDP, Granddaddy Purps)

If you’ve not heard of the Granddaddy Purple weed, you might know it from the abbreviation “GDP.” It’s also affectionately called Granddaddy Purps.

Whether you’re a user or a cultivator, you’ll learn about the effects and medical benefits that this Indica-dominant cultivar offers and how to grow and harvest a substantial yield. But first, here’s a summary of the Granddaddy Purple strain info: 

Granddaddy Purple Strain Info

Granddaddy Purple strain description

The first thing you need to know about the strain Granddaddy Purple is that it’s an indica offspring of Purple Urkle and Big Bud.

Its genetics explain why it produces large, violet buds. The size of its nugs is a trait it inherited from Big Bud, while its colors come from its other parent. Purple Urkle is also responsible for the Granddaddy Purple strain’s berry aroma and grape soda taste. Some describe its fragrance as reminding them of their childhood candy store.

The first impressions you’ll get from the cultivar’s mature appearance are its dark purple nugs coated with bright orange hairs and snow-like whitish crystal trichomes.

Granddaddy Purple strain effects

Aside from what you can expect when you grow the Granddaddy Purple strain, the cultivar also offers users many benefits, whether you consume it for recreational or medical reasons.

As it’s mostly-Indica, it’ll uplift you before making you feel euphoric, then totally relaxed. Some users, especially newbies, may feel uncomfortable because of the high Granddaddy Purple’s THC level, which can be up to 24%. However, rest assured that GDP is not reputed to cause paranoia or raise your anxiety level.

We recommended that you consume the strain during weekends or in the evening when your daily tasks are complete because it’s a natural sedative. 

The Granddaddy Purple marijuana strain will make you feel completely relaxed from head to toe. As your muscles loosen, you’ll experience heaviness in your head. All you’ll want to do is slouch on your couch. It’s best to give in to the sensation as it’ll be challenging to stay awake.

The Granddaddy Purple strain effectively relieves anxiety and stress because the relaxation it provides is immediate and long-lasting. It’s a great way to chill out when you have troubles on your mind.

Be prepared with munchies as the cultivar also stimulates your appetite. It’s advisable to avoid spicy food unless you’re accustomed to it because everything you eat will have a stronger than usual taste.

Granddaddy Purple marijuana is reputed for helping people with several physical and emotional ailments because it was created for medical use

The mild euphoria experienced is helpful for people with depression, and because of its sedative effects, it reduces anxiety and stress

The Granddaddy Purple strain is popular among users for pain relief, including easing migraines and headaches. Its ability to improve users’ palates has made it useful for people with loss of appetite due to chemotherapy.

You may experience dry eyes and cottonmouth, which is typical when consuming any cannabis strain. When using Granddaddy Purple marijuana, keep yourself hydrated and use eye drops when necessary, and you’ll be alright. It’ll help if you prepare those items beforehand, as you’re likely to be glued to your seat afterward.

Granddaddy Purple weed strain grow information

Cannabis cultivators will be pleased to know that GDP plants are tough, durable, and resistant to pest infestations and molds—the cultivar flourishes in dry and ventilated environments. As such this strain is suitable for growers of all levels.

Another reason growers favor the Granddaddy Purple marijuana cultivar is its extra-large buds compared to other weed strains. This is why the plant has thick and strong branches to hold the heavy nugs. 

One minor challenge for growers is that they should take note of the humidity conditions when growing this cultivar. The Granddaddy Purple strain is sensitive to damp areas. The pores on its leaves will close, reducing the absorption of the liquid nutrients you feed it, and the plant will not produce to its potential.

Aside from those precautions, the GDP is very versatile. You can cultivate it indoors and outdoors. The Granddaddy Purple weed will grow effortlessly if you feed it well and keep it warm. A standard nutrient pack is a perfect way to bump up its vitamins and minerals quotient. Be prepared to support its sturdy branches.

You can expect yields within a relatively short period. When growing in your garden, the cultivar will flower between early to mid-October, and you can collect its buds two weeks later. 

The Granddaddy Purple strain outdoor yield provides a bountiful 17.6 ounces per plant when grown correctly. This abundant harvest is why commercial cultivators love the GDP.

If you cultivate it indoors, the Sea of Green (SOG) method is most effective. Your plants will give you 17.6 ounces of buds per square meter. Remember to keep them free of moisture.

Growing great very sweet smells


Great strain for sleep. The answer to my hopes to sleep again.


Received 5 seeds and all germinated. They were all very uniform. Trouble free and very easy to grow. Dropped the room temp 8° which really released the anthocyanins. Plants yielded 11 to 13 ounces apiece dry.Definitively a nice plant and worth growing.


Seeds spouted quick! Very healthy as well!
