Plants respond well to training techniques like LST and topping, which help maximise light penetration and significantly boost yields. Due to the buds’ density and size, you may need to provide extra support during late flowering and carefully monitor humidity to prevent mould. Consider growing in super soil with organic nutrients for optimal flavour development and those signature deep purple colours by exposing plants to cooler night temperatures late in flowering.

GrandDaddy Purple finishes flowering in approximately 65 days. Indoors, plants remain manageable at 100 cm and yield roughly 600 g/m². Outdoors, plants can reach up to 180 cm and yield up to 1000g per plant by mid-October.
