Bermuda Triangle is GTR Seeds' feminized F1 hybrid from Triangle Kush S1 crossed with AVL, the breeder's in-house Auto Varin Lime line. The brief is specific: keep Triangle Kush's depth, add the lime line's brightness, and fix the parts of Triangle Kush that frustrate growers.
Where It Comes From
GTR Seeds is the THC-focused arm of a long Oregon breeding story. The company has been Oregon-grown since its 2015 founding, when it operated as Oregon CBD, and its founders Seth and Eric Crawford bring more than 35 years of combined breeding experience between them.
They built the reputation on being first to produce consistently stable, reliably feminized F1 hybrid seed in high-CBD, CBG and CBDV lines. The company kept heavy-hitting recreational varieties in reserve for years while seed-sale restrictions held them back, then re-emerged as GTR Seeds to release the THC-rich material — Type I, Type II, THCV and triploid lines.
The Cross
Triangle Kush S1 × AVL, sold as feminized seed and classified by the breeder as an F1 hybrid.
The S1 notation is the part worth understanding. It means a selected Triangle Kush was self-pollinated to make the parent line rather than crossed to a male — a way of locking a clone's traits in place before hybridizing it. Triangle Kush is the Florida-associated OG-family cultivar; AVL is GTR's own Auto Varin Lime work.
GTR is direct about the payoff: the F1 offspring show what the breeder calls dramatic improvements over the Triangle Kush parent on its own, which is the entire reason the cross exists.
Where To Get It
It sells directly from GTR in 5, 10, 100 and 1,000-seed packs and has been in the catalog since 2023. There is also a Bermuda Triangle Seedless triploid version — a sign the line is being pushed toward production rather than novelty.
The High Rise Take
This is what happens when people who spent a decade doing rigorous hemp seed work point that same discipline at a temperamental OG clone. Bermuda Triangle is a breeding-program artifact in the best sense: it exists to solve a specific problem with a specific plant.
