Prūf No. 38: Steel Bridge

Steel Bridge

Prūf No. 38

This monstrously flavorful plant has moved quickly into our hearts. Golden Goat parentage is quickened by the intensity and additional chemistry of the TH1. This is our first exclusive beta-caryophyllene dominant plant. This rare profile strikes a balance from generous amounts of limonene, myrcene and the far more rarely occurring guiaol.

Among numerous fresh releases of new strains bred and cultivated at Pruf, Steel Bridge has particularly refreshed the excitement of smoking flower. I tried No. 38, a batch that tested at 24.5 percent THC and 4.44 percent total terpenes. Made from combining the beloved Golden Goat cultivar and TH1 (#3), this plant is an example of successfully customized cultivation to bring out rarer, less common terpenes, with a dominant concentration of beta-caryophyllene. That may not mean anything to you—it wasn't something I necessarily sought out—but what it means is this cultivar may produce effects you've never experienced before. The taste is similar to citrusy, skunky varieties like Island Sweet Skunk, like a tropical breeze from very unfamiliar, untraveled waters.

Every cannabis strain possesses a unique ratio of THC to CBD. THC (tetrahydrocannabinol) is the psychoactive component of cannabis. CBD (cannabidiol) is a therapeutic compound showing promise at relieving pain and anxiety. A Type 1 plant, with high THC and low CBD, is more intoxicating than a plant than a mixed ratio Type 2, or a Type 3 high CBD/low THC plant.
