Aroma & Flavour
Granddaddy Purple Autoflower is the autoflowering sister of the well known and loved Granddaddy Purple. These formidable genetics simply had to get the ruderalis makeover. With 75% indica genetics and 19% of THC, Granddaddy Purple Auto seeds are a must-try for those who enjoy cannabis bud with relaxing properties and loads of flavour.
GDP Auto weed strain has a superb genetic pool created from Purple Urkle (Afghan x Skunk) and Big Bud Auto (a Mendocino Purps pheno). This indica-dominant profile offers 75% indica, 20% sativa and 5% ruderalis influences.
The rich heritage culminates in a moreish terpene profile offering complex, multifaceted aromas. Juicy notes of blueberry mix with other fruit for a well-rounded, inviting fragrance that is undercut by herbal undertones and a touch of pine—definitely a flavoursome experience.
Granddaddy Purple Autoflower makes for a relaxing smoke that can help wind down and catch some z's, while lifting the user up. These seeds suit both indoor and outdoor growers, producing manageable, medium-sized plants with an easy-going variety lifecycle of 10–12 weeks.
