Many fanatic growers from Canada and the USA have already grown the Granddaddy Purple plant and in case you haven’t, this awesome strain is probably high on your list. The beautiful purple-colored plant has its origin in Bay Area (California) and is the result of a cross between the powerful Big Bud X Purple Uncle. Nowadays this strain belongs to the absolute cannabis top, so if you haven't taste it before, buy our Granddaddy Purple feminized seeds, roll up your sleeves let's get to work! 

Granddaddy Purple seeds

Our Granddaddy Purple seeds are known for their high fungal resistance, so the change of plant diseases is very limited. The seeds are therefore the perfect choice for both novice growers without (much) experience and advanced growers who like high quality weed. Just like almost all other weed plants, the plants can be grown indoors, outdoors or in a greenhouse. 

Plant height

Granddaddy purple seeds grow fairly short plants to an average height of 60 to 100 cm. However, outdoors the plant can easily reach a height of 180 cm.

Flowering time

Although the flowering time can be partially controlled by the grower, the plant is usually ready for harvest after a flowering period of 8 to 11 weeks. During flowering, the buds are richly covered with a thick layer of THC trichomes and beautiful red hairs.


The harvest is the largest outdoors. Outdoor growers preferably harvest in mid-October and can harvest a maximum of 450 grams per plant. Indoor growers harvest on average a maximum of 400 grams per m2. Of course, these numbers are based on healthy breeding and ideal conditions, but advanced growers must certainly be able to achieve these results.

Effects of Granddaddy Purple weed

The effect of Granddaddy Purple weed is, due to its high THC content of 23%, very powerful and provides a calming effect on your thoughts and a total relaxation. Therefore the weed is very suitable to smoke in the evening. In addition to these effects, users report that they feel euphoric and a bit giggly.

Smell and taste of Grand Daddy Purple

Granddaddy Purple has a number of distinct scents and flavors that match the expectation of this purple weed. For example, you clearly smell the sweet scent of berries and grapes combined with delicious sweet fruity flavors. You will definitely taste earthy pines, but also the sour notes of citrus fruits. In short: a delicious weed with a complete taste sensation.

    Definitely deserves the five stars!

  2. Christoph (verified owner)

    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.
    Many thanks for the quick delivery and good customer service.

    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.
