Coastal Seed Co’s is a Sativa dominant cross of two killer landrace strains that is sure to impress any Sativa lover. Plus it has a flowering time of just 10 weeks!

Oaxacan is a 100% pure Sativa strain that is native to the Oaxaca region of Mexico. Named for its super gorgeous appearance, Oaxacan Gold packs a punch of bright daytime effects that will get you up off the couch almost immediately. This baby has beautiful popcorn-shaped bright neon green nugs with lots of vivid orange hairs and a coating of glitter amber crystal trichomes that are practically dripping with sweet syrupy resin.

Colombian is also a 100% pure Sativa strain that is a classic Landrace strain from Santa Marta, Columbia. Colombian nugs have an infamous classic aroma of sweet lemon skunk and an equally delicious taste of sweet lemony skunk with a hint of tangy lime upon exhale.

Because of these potent Sativa effects, Oaxacan Columbian is said to be ideal for treating patients suffering from conditions such as muscle spasms, chronic pain, ADD/ADHD, and depression.
