Easy to gtow hybrid, mould-resistant with huge yields, sky high cannabinoid production. Ideal for humid and wet climates.

Grandpa's Stash R2 is agreat strain for both the beginner and expert grower alike. A three-way cross between Super Skunk, Afghan Kush and OG Kush, Grandpa's Stash R2 produces very big harvests with very high total cannabinoid levels in a mould-resistant package.

Grandpa's Stash R2 grows in all environments and is perfect for both wet locations and those with high humidity with its natural resistance to both mould and powdery mildew. Plants are very easy-going and its relatively fast flowering time makes it suitable for short growing seasons outdoors. Indoor flowering times are 56 - 60 days. Plants are stocky and bear contiguous buds all down the stems following a fast onset of florescence providing very big crops..

Terps. produce earthy aromas of sweet pine, chem and Skunk. With total active cannabinoid production of between 25 - 30% this is a strain with very high levels of potency.
