Tips for Growing Granddaddy Purple Cannabis

Ever wanted to grow your favorite strain? Leafly and Botanicare are teaming up on a series of grow guides that will equip you with all the tips and tricks you need to grow different strains successfully.


Strain Overview:  A timeless indica classic born in the early 2000s, Granddaddy Purple is a genetic cross between Purple Urkle and Big Bud. This California native produces large buds rich with trichomes and ripe blueberry flavors. Characterized by its sedating attributes, GDP can help with pain, nausea, and many other symptoms.

Grow Techniques: Granddaddy Purple is best kept indoors so an ideal climate can be maintained while the large buds take shape. Pruning and humidity control are crucial to keeping powdery mildew and bud rot at bay. Granddaddy Purple is a great strain to explore training techniques that will further increase yields of this vigorous plant. This strain is well suited for both soil and hydro grows. 

Flowering Time: 8 weeks

Yield: High

Grow Difficulty: Easy to moderate

Climate: GDP prefers a dry climate and can handle a little cold if grown outside. Ideal temperature ranges between 70 and 80 degrees Fahrenheit.

Indoor/Outdoor: Keep this strain inside unless you live in a location with dry fall weather; the large colas are prone to rotting if moisture is present.

Feeding: Products high in phosphorous will help keep the buds growing dense and healthy during GDP’s flowering stage. Bat guano and kelp are unique organic products that can be used to increase the strength and development of the plant and buds.
