Indoor Pure Grapes is an indica-dominant cross between two infamous strains: OG Kush and Purple Punch. The result is a diverse terpene profile. Upon cracking open the dense nugs, users can detect an aroma of cake and fruit. On the exhale, you can detect the concord grape flavor that gives the strain its name. The effects and flavors of the Purple Punch point back to its genetics. Purple Punch is a heavy Indica plant with strong flavors of grape throughout. Purple Punch is used by some to treat health problems such as insomnia, minor body aches, and stress. The OG Kush, another heavy indica plant, is known for its skunky aroma and hard-hitting effects.
