Strain Description

The Grandaddy Purple strain is a legendary Indica-dominant hybrid combining Purple Urkle with Big Bud. With around 22% THC and 0.60% CBD, it delivers the classic deeply relaxing and euphoric high across body and mind. Plants remain compact and bushy, producing dense buds with a rich profile of berry, grape, citrus, pine, and sweet notes.

Growing Information

This strain is beginner-friendly and thrives in both indoor and outdoor settings. Flowering takes 8 to 10 weeks, with harvest in October. Compact size (up to ~4 ft indoors, up to 6 ft outdoors in sun) makes it manageable, while minimal pruning supports airflow. Yields range around 400 g/m² indoors and 550 g per plant outdoors.

Quick Grow Tips

  • Lighting: Use a 12/12 photoperiod to trigger flowering after the veg stage
  • Nutrients: Use typical indica‑dominant feeding schedules, shifting toward bloom nutrients when buds begin
  • Watering: Maintain airflow & trim lower growth to reduce mold risk
  • Environment: Ideal for moderate climates; control humidity and temperature, especially during late flowering

Summary

Grandaddy Purple Feminized Seeds deliver potent Indica effects with berry‑grape aromatics in a compact, easy‑to-grow plant. Expect harvest-ready buds in 8–10 weeks, ideal for beginner growers seeking high quality with minimal space or maintenance requirements.

"1.) I never germinate seeds as CK suggests. However, I wanted the "warranty". I germed all 5, all 5 had 1/2 tails within 72 hrs. 100% 2.) I screwed up 3 transplants, all 3 bounced back fast. Strong genetics 3.) She takes 4 rounds of topping with minimal shock. 4.) She grows fast, low and wide. 5.) As consistent as the early 2000s GDP as I've found. Beautiful genes."

"Crop king is great every time. No problems with seeds, fast discrete shipping to Michigan. Good customer service, used online chat. Excellent grow indoors, very strong smell in flower. Sweet smelling Solid buds. Strong cloner too, and with aero cloner and gel had roots in under 2 weeks. Friends all love the happy, feel-good buzz, and want more, even the heavy smokers with high tolerance are asking for more. One buddy says it helps his hip pain at night and is able to sleep. I found No purple colors on any of the plants which I thought would be cool to see but not a dealbreaker. Everyone loves it so much I’m going to run this one for a few more harvests. Bubbleponics with 600 hps, 4 plant Scrog in 4x4, 2-3 zips per plant in 8 week flower. Thumbs up!"

"I purchased these seeds and not 1 popped. I've purchased any times from Crop Kings and have never ever had an issue up until now. I'm not sure what the deal is. I was looking forward to trying this strain..."

"This was my first grow, bought these seeds and all 5 sprouted. Light was too far away and they all stretched, and I had to prop them up. Put them in hydroponic system for 2 months and they wouldn't even grow roots, most other plants in the system for root rot, leaf problems, and died. after trying everything realized my ph tester was not working and the ph was at 1.5!!! Corrected issue and the plants shot to life filled the bucket with beautiful roots and growing like crazy. How these plants held on for two months enduring without a single plant dying is beyond me. Definitely buying again!"

"These seeds had a 100% seed rate but compared to the other strains this one seems to be slow growing, stunted a bit and more delicate to its environment. all other strains are growing like crazy and this one requires all my attention. Grand daddy Purple is one of my favorite strains though so will be worth the extra effort!!"

    i’ve always heard that indica’s grow short. well, my GDP grew 13′ and was topped once. Hindu Kush 11′ and topped once. actually, it didn’t seem to matter what variety i grew they all got at least 10′ and didn’t have hardly any pests or disease growing here in eastern oklahoma. also, i’ve read that alot of folks are afraid to take leaves off the plant in mass. been doing that for 50 yrs and it makes my plants grow more vigorous. all of the leaves taken grow back very quickly!
