Many avid recreational and medicinal growers from Canada and the USA have already grown the Granddaddy Purple feminized plant once, and if not, it is probably high on their list. The same is true for Dutch home growers.

This beautiful purple-colored plant originated in the Bay Area (California) and resulted from a cross between the powerful Big Bud X Purple Urkle. She has since become one of the absolute top cannabis strains due to her generous yields and layered fruity flavors.

Have you never grown Granddaddy Purple? Then buy these feminized Granddaddy Purple marijuana seeds and assure yourself of high-quality weed.

Why you should buy feminized Granddaddy Purple seeds:

  • Stunning appearance with a purple glow
  • High-quality weed and generous yields
  • High mold resistance 
  • One of the most sought after strains in the USA, Canada, and the UK

Growing Granddaddy Purple seeds (indoors and outdoors)

As with almost all other cannabis plants, you can use Granddaddy Purple cannabis seeds for indoor, outdoor, or greenhouse cultivation.

However, it is essential to know that the plant prefers a humidity level of around 50% for successful growth and should also be well ventilated. Is it too dry or too humid? Consider growing your Granddaddy Purple seeds indoors, where the growing conditions can easily be adequately regulated. Moreover, it is a plant that desires ventilation, just like its parent (the Big Bud).

Granddaddy Purple is also known for its high resistance to mold. Therefore, you don't have to worry about plant diseases. This makes our Granddaddy Purple feminized seeds the perfect choice for novice growers with no experience and advanced growers who like to grow high-quality weed.

When you start growing Granddaddy Purple, you'll soon notice that she's a true Indica. It doesn't take long for the plants to grow into compact, bushy bushes. Her Indica dominant traits are also reflected in her internode spacing and broad-leaved fingers, with which she efficiently absorbs sunlight.

Flowering time

Although the grower can partially control the flowering time, the plants are usually ready for harvest after a flowering period of 63 to 70 days.

GDP's buds always look great; they are thick, have a compact structure, and have beautiful purple hues that range from the darkest purple to mauve and light green that you can see through a layer of glistening white trichomes.

Plant height

Granddaddy Purple is a relatively short plant and grows to an average height of 60 to 100 cm indoors. Outdoors, however, the plant can grow considerably to a maximum height of 180 cm.

Granddaddy Purple feminized yield

Granddaddy Purple obtains the best harvests when grown outdoors. In the Northern Hemisphere, the plant is preferably harvested in mid-October, and under ideal conditions, it will yield 400 to 600 grams per plant.


However, indoor growers will not be disappointed either. Indoor growers can harvest up to 500 grams per m². Of course, these numbers are based on healthy growth and under ideal conditions, but advanced growers should undoubtedly be able to achieve such a harvest.

Effects of Granddaddy Purple feminized

Granddaddy Purple weed is an excellent weed for the evening. The weed is potent and immediately noticeable thanks to its high THC content of typically 23%. It offers a calming effect on your train of thought and provides total relaxation. In addition to these effects, users report feeling happy, euphoric even.

Side Effects

High doses can lead to anxiety and paranoia. It is therefore advisable to take it easy. Other side effects include dry mouth and eyes.

Smell and taste

Granddaddy Purple features distinct smells and tastes that exactly match the expectations of this purple weed. For example, you can smell the sweet aroma of berries and herbs combined with delicious sweet fruity flavors. Moreover, taste earthy pine and tart, slightly sharp notes of citrus. In short: a tasty weed with a complex taste sensation.


Granddaddy Purple was created in 2003 and was initially developed by Ken Estes. This beautiful purple-colored plant originated in the Bay Area (California) and resulted from a cross between the powerful Big Bud X Purple Urkle.

Very nice Plants and good delivery.

Dale Baker (Verified customer) 2022-10-18

Not really a review although, I'm quite happy with the plants. There much more then 180cm tall. More like 71/2'. But my question is, I live in NY an we're starting on the edge of cold weather. The GDP has not stared to turn purple. It's mid Oct. In an outdoor grow. Anyone have any idea how much longer? I would hate to lose then to cold weather. We have had 2 light frosts. I've covered them. But remember there over 7' tall. Thanks All for any in put.

Ice (Verified customer) 2022-08-18

Made some awesome pictures of the end results but unfortunately there is no upload option here so i can't share. Beautiful plant. Don't let her fool you at 6 or 7 weeks. She looks ready but she is not .. the growth slows down but she still is busy fattening up. The tops were approximately 7cm in diameter. Greedy plant for water so i gave her plenty. She is also capable of taking in alot of feeding but that will just make her flower too quickly. So next year i will restrict more on the feeding as i have the motherplant continuously on grow mode and clone from there. Excellent quality!

Jason (Verified customer) 2022-04-22

Quick shipping and super stealthy. Large buds and beautiful colors. Took 13 weeks to finish in flower, awhile longer than expected. Nose was earthy, like dirt, even though it was grown in Hydro.

ian (Weedseedsexpress) replied on 2022-04-25

Hey Jason, In the end, the plant can have a mind of her own. It does seem like the end result was more than worth the wait. Thanks for the review, very much appreciated! Cheers, Ian

Mike S. (Verified customer) 2022-04-08

I don’t usually write reviews but here goes. Got these seeds quickly. 100 % of seeds grew into the most beautiful plants I have ever grown. Big firm buds, and the smell was amazing. The smoke is great a nice high with a kick in the a$$ to get to doing odd jobs around the house. The wife really likes it too so win win. I just ordered the Northern Lights X Big Buds. Again 100 % germination. They are now 5 days old and looking great. I will purchase all my future seeds from Weed Seeds Express. Thanks WSE for a most present ordering and growing experience.

I’m so happy with my gdp! Shopping: ..kept great contact and rapid response time with questions. Seeds: planted three, saved two. I wish I could post a pic I just took with a soda can sitting next to the center most colas for comparison on one of my outdoor ones. They (two of the three), are HUGE! I harvested my indoor one and it is 22 days into cure. It is a very nice smoke, and powerful, too! I harvest my outdoor two next Saturday (10/2/21 @ Phx suburb), and I’m expecting nothing less than perfection! Thanks for the quality seeds! I’m shopping for my next project as we speak!

Hi Ron, Thanks for leaving the wonderful review! Would be nice if you can send us a picture of your plants. We are happy to hear that you will visit our site again. Have a nice growth!🌿 Cheers, Vincent

NR (Verified customer) 2021-08-25

I grew 1 seed from 5 that I’d purchased as part of a multiple strain grow. Although the plant didn’t show any purple colouring the yield was outstanding and by the best performing plant out of 5 that I was growing. I can’t comment on the effects or taste as it is currently in the drying phase. I would recommend this strain on the basis of yield. Thank you WSE

Marc (Weedseedsexpress) replied on 2021-08-26

Hi NR, Thanks for leaving a review. I'm glad to read you're happy with the results, even though the purple didn't pop. There are some things you can do to trigger the purple color, we've written a blog about it. Check it out here: Have a great one! Cheers, Marc

I received my 20 seeds today, no extra seeds. I thought I would get a couple free. Three of the GDP Feminized seeds were yellow. Germinating them now, hopefully they will come up. I might have a really good review in a few days, hopefully.

Diana (Verified customer) 2020-08-24

hi, i was wondering what soil you used for the gdp? ( i tried with ph 5,5- 6,5 with one of the seeds and it didn’t work) did any of you try with coco coir?

Jeremy (Verified customer) 2020-05-22

Got my seeds! It took a month but it was a great start to the May long weekend and an awesome surprise when I got home from work. All these crazy germination methods are crazy! I’ve planted 2 seeds of granddaddy purple 2 seeds of godfather OG and 2 seeds of northern lights On Saturday afternoon and it’s now Thursday night and all of the plants are over 2 inches tall. Just put the seeds in water for 18 hrs and then plant the seeds into i good seedling soil (promix seedling soil) and lightly water the soil just so that the soil is damp ( not running out the bottom! ) Even use a spray bottle to water the soil if you want. Your plants should pop up in about 48 hrs and if you have a good seedling growing environment with about 60-70% humidity and temperature of 70-80 Fahrenheit the plants will grow rapidly! Remember young plants take in water through leaves so high humidity is needed. ( don’t just drench your plants in water!!)

Riley (Verified customer) 2020-05-11

I'm a begginner grower here, and I grew 3 seeds outdoor and they yeilded about a half pound each. Well worth the money, thanks heaps.

goodremallouise45 (Verified customer) 2019-10-25

All my GDP seeds have germinated 100% and are in their first stage but all have symptoms of being older seeds and have had the struggles getting the seed husks off needing help, having not grown long enough tap root before throwing off the seed husks, some got stuck under soil for too long before reaching the top and needed help also, all have gotten through this rough stage are green, strong and growing ok, hoping none of these matters effect their future yeilds and potency, will review again after they've made it to the next growth stage,

goodremallouise45 (Verified customer) 2019-10-17

Received my GDP today on time✔ descreet shipping✔ great customer service✔ 4 stars for now, will review again after they've germinated Thanx guys 👌

Christoph (Verified customer) 2019-08-20

I ordered this strain because I read that specifically this strain helps for muscle spasms. I can definitely say it helps till a certain extent. Growing the seeds was quite easy and the color on the buds is really typical for the weed. It was not as purple as I have seen on other picture, but nevertheless beautiful. Bless Many thanks for the quick delivery and good customer service.

Donnie (Verified customer) 2019-06-20

marcis (Verified customer) 2019-06-03

Can't imagine any better strain than the GDP is. Such a color rich plant which super dense buds! I grow regularly and the granddaddy has become one of my favorites, I grow these at least once a year. Currently growing gdp for the first time using genetics from weedseedsexpress and they are doing great. If it stays like this I will buy them with you each year David. Just send you the pics by mail.

Wethington (Verified customer) 2019-05-16
