Granddaddy Purple strain

Our Granddaddy Purple seeds are known for growing strains with a high fungal resistance, so changes that you plant will suffer from diseases during growing is very limited. The seeds are therefore the perfect choice for both novice growers without (much) experience and advanced growers who like a high quality weed. Just like almost all other strains, the plant 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 when grown indoors. However, outdoors the plant can easily reach a height of 180 cm.

Flowering time

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


Your harvest will be the biggest when growing outdoors. Outdoor growers preferably harvest in mid-October and can harvest up to 450 grams per plant. Indoor growers harvest on average a maximum of 400 grams per m2. Of course, these estimations are based on healthy breeding conditions, but advanced growers must certainly be able to achieve these results.

Effects of Granddaddy Purple weed

Due to its high THC content of 23% the effect of Granddaddy Purple weed is very powerful and provides a calming effect on your mind. The weed is therefore 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 Granddaddy 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.

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!!)

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

I love the grandaddy P, this was a legendary grow guys! Yield was awesome and pretty easy to grow outside. Definitely deserves the five stars!

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
