SR71P

SR71 by Purple City Genetics is an indica-dominant, feminised hybrid that combines classic OG genetics with modern US breeding. The cross between Oaksterdam OG and Street Guru produces vigorous plants, high yields and a very intense terpene profile. The strain impresses with a short flowering time of around 8–9 weeks, stable growth and great results, both indoors and outdoors.

This makes it well suited for growers looking for reliable and high-performing genetics. In terms of flavour, SR71 has a loud, gassy aroma, complemented by earthy, rubbery and doughy notes – typical of modern US strains.

• Lineage: Oaksterdam OG x Street Guru
• Genetics: mostly Indica
• Flowering: 8 - 9 weeks
• Smell: gas, rubber, biscuits, dough
• THC: 25%

Purple City Genetics – Oakland, California

Purple City Genetics, or PCG for short, has been around since 2008. They are based in Oakland and started out as a cannabis collective. Over the years, as the cannabis scene in the States kept shifting, they adjusted too. These days, they breed for everyone from home growers to large-scale farms, but they still keep their quality standards high. They have picked up plenty of awards along the way at different events and cups. Their strains are easy enough for beginners setups to work with, but experienced growers will get a lot out of them too.

PCG’s catalogue is not just about yield – though they do that well – it is about flavour and potency too. They put out some pretty wild crosses, and their terpene profiles are always something to talk about. Sometimes they release small batch strains that disappear fast, so it is worth keeping an eye out.
