OG #18 (also known as Private Reserve,) is a sour phenotype of OG Kush from Reserva Privada, a subdivision of Amsterdam’s DNA Genetics.
When DNA created a series of feminized OG Kush phenotype seeds, OG #18 made a lasting impression with its sour, diesel flavor profile and significantly higher yields than the original OG Kush. OG #18 won 1st Indoor Hydro at Spannabis Cup in 2011, 2nd Indica at High Times’ Cannabis Cup in 2009 and 3rd Indica at High Times’ Cannabis Cup in 2007.
The strain reportedly offers deeply relaxing and sedative effects that leave the user with a clear mind, an elevated mood and possibly a case of the munchies.
