Granddaddy Purple Feminized Information


Granddaddy Purple (aka Grand Daddy Purps) is one of the most popular indica strains on the West Coast and the most well-known ‘purple’ cannabis strain in the US.

Creation and Appearance Created in 2003 by Ken Estes in the San Francisco Bay Area, Granddaddy Purple is a hybrid of Purple Urkle and Big Bud. It combines the deep purple hue of Purple Urkle with the dense, oversized buds of Big Bud. The dark purple buds are complemented by bright orange hairs and frosted white trichomes, making it a photogenic strain.

Popularity and Similarity to Grape Ape From San Francisco to Los Angeles, Granddaddy Purple is highly sought after for its striking appearance and classic indica effects. Some growers and dispensaries claim it is almost identical to another famous purple strain, Grape Ape, due to their similar lineage, look, taste, and effects.

Aroma and Taste Granddaddy Purple has a potent grape aroma and a sweet grape taste that lingers on the tongue. The effects are long-lasting and provide a smooth, even feeling. Surprisingly, for an indica, it offers an alert and energetic buzz rather than a sedating one, making it a good choice for outdoor activities.

Effects Granddaddy Purple is perfect for nighttime use. It provides both mental and physical relaxation, quickly leading to a smooth body buzz and classic indica couch-lock. It is immensely relaxing and ideal for ending the day.

Medical Benefits This strain is ideal for pain management and can also help with insomnia, depression, and anxiety. Novice users should start with a small amount, as it can be very potent.

Growing Information Granddaddy Purple grows best indoors but can also be grown outside. Flowering takes about 70-77 days indoors, with outdoor harvests ready by early October. The plant may need support as the oversized buds can weigh it down. Indoor yields can reach 4 ounces per plant, while outdoor yields can exceed 3 pounds per plant. For best results, maintain temperatures in the 70s and humidity between 50-55%. The plant is happy in both hydro and soil setups, grows to about 3 feet indoors or up to 8 feet outdoors, and has a short, bushy stature with tight internodes and dense dark green to purple leaves.

Awards Granddaddy Purple has won several awards, including the Inglewood Medical Cannabis Cup in 2004 and the Green Cup in 2004, 2005, and 2006.



  • All Cannabis strains, require a full spectrum nutrient complete with the macro nutrients such as Nitrogen, phosphorus, and potassium and the secondary nutrients and micronutrients like, calcium, sulphur, hydrogen, magnesium, manganese, carbon, iron, zinc etc.
  • For coco/perlite grows, we recommend Nutrifield Coco A&B for use throughout the entire grow, with Nutrifield Organic BUD BURST at the beginning of the flowering phase right through to harvest.  As bud burst is organic, this ensures a nice smooth, super clean tasting smoke that you will love!
  • For soil based growing (not recommended), just make sure you use a high quality soil rich in organic matter such as compost and manure.   Note that manure if high in nitrogen which you’ll want to reduce during the flowering stage. 
  • During the flowering stage, change the ratio so you are using up to three times more phosphorus than nitrogen and potassium. Also continue to add in secondary nutrients such as iron, copper, and manganese.  The best way to do this is simply to use orgnanic Bud Burst during flowering all the way as this will ensure a smooth finish with no chemical taste.   Amazing stuff!
  • For organic grows, we recommend Aptus Baseboost organic nutrient   with coco/perlite 70/30 ratio.   This stuff is highly concentrated so a little goes a long way making it great value.     Simply add the pellets to the coco as per the instructions and it will completely transform any inert growing medium into a powerful full spectrum grow media.. 

Growing Tips

  • Your plants will need consistent air flow and good ventilation, whether you are choosing the perfect spot for an outdoor grow, or are growing in an indoor grow room. They need air that is rich in oxygen, to help prevent respiration, deter any pests, and allow your plant to grow healthy and strong. Use fans to help circulate air, or if you can afford it, exhaust systems are an excellent choice.

Why buy ‘Feminized’ Seeds

  • Marijuana plants are either male or female.   The male flower produces sacs or pollen designed to fertilize the female flower which produces white pistols designed to absorb the pollen.   If no male plants are present in the growing area, than the female plant will just grow larger and larger flowers in search of pollen.   These flowers are the cannabis buds that we all know and love.   The male plants hold only minuscule amount of THC, while the female flowers are oozing with THC crystals (the good stuff).   For this reason, marijuana growers are seeking only female plants in the grow room (unless they want alot of seedy buds).Feminsed seeds have been cultivated in a precise way so that the seed is genetically more likely to produce a female plant.   Autoflower seeds automatically transition from the vegetative phase to the flowering stage without you needing to adjust their light exposure.   Fore more detailed growing information, see our in depth grow guide.
