Why you should buy Granddaddy Purple seeds
Granddaddy Purple isn’t trying to reinvent the wheel. She’s just been rolling over everything in her path since the early 2000s. Thick purple buds? Check. Dense layers of trichomes? Absolutely. A grape-sweet aroma that fills the room before you even open the jar? You better believe it.
This is the kind of weed that doesn’t whisper. It wraps you up, gently at first, then melts you into the cushions before you realize your playlist's been on pause for twenty minutes. GDP is a mood reset in plant form. She’s calming, euphoric, and so heavy you might forget how to finish your sentence, in the best possible way.
And when it’s grow time? She behaves like an old friend. Stable, predictable, and surprisingly easygoing. It’s not hype. It’s heritage.
Strain Overview
Origin
Born in the Bay Area back in 2003, Granddaddy Purple came from the minds that crossed Purple Urkle with Big Bud. The name doesn’t lie. She’s got the colour from Urkle and the girth from Big Bud, making her one of the most iconic West Coast indicas of all time. A medical scene staple that turned into a global cult classic.
Effects & flavours
It starts in the head, a warm sense of ease that makes you giggle at nothing and nod along to conversations you're not even part of. Then comes the full-body cascade. Muscles loosen. Stress exits stage left. It’s deep, physical, and perfect for nights when you want the world to quiet down.
flavour-wise, it’s rich and unmistakable. Think berry and sweet grape up front, with earthy, herbal notes on the exhale and just a whisper of pine. Tastes like it smells, loud and lush.
THC & CBD Levels
Expect around 23% THC, which is plenty when paired with this kind of relaxing profile. CBD clocks in at 0.40%, giving just enough balance to smooth things out. Strong, but not overwhelming, unless you go back for that third hit too fast.
Terpenes
GDP leans on camphene, valencene, and linalool to deliver that sweet-meets-funky punch. Camphene brings the piney sharpness, linalool adds that lavender-like chill, and valencene rounds it out with citrusy brightness. The result is a complex, deeply aromatic experience that lingers.
Growing Granddaddy Purple Seeds
Grow Difficulty
Beginner-friendly with pro-level results. Granddaddy Purple is sturdy, reliable, and a dream for anyone still fine-tuning their grow setup. She handles stress well and shrugs off mould and mildew without making a fuss. Just be ready to support those heavy buds late in flower.
Indoor vs. Outdoor Growing
She stays compact indoors, usually between 24 inch and 39 inch, which makes her perfect for tents or limited vertical space. Outdoors, she stretches a bit more, up to 71 inch in the right conditions, and rarely below 47 inch, but still keeps a bushy structure that’s easy to manage.
Mediterranean and temperate climates are where she really shines, but she’s tough enough to handle drier regions too. Whether you’re in a greenhouse or growing guerrilla style in the hills, GDP adapts well.
Flowering Time & Yield
Expect a flowering time of 63 to 70 days. Indoors, yields hit around 14.1 oz to 17.6 oz. Outdoors, you’re looking at 14.1 oz to 21.2 oz, assuming she gets good light and airflow. Not the fastest, but the payoff is worth every day of the wait.

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!

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.

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!!)

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.

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.

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,
