In House Genetics is a United States cannabis seed breeder best known for Slurricane and a deep catalog of resin-forward hybrid crosses. It operates as a micro-breeder, releasing new crosses on a rolling monthly cadence in limited runs rather than maintaining a fixed permanent line. Its seeds reach growers through seed banks and nurseries rather than a company storefront.
The catalog
The line is dominated by feminized photoperiod seeds sold in limited packs and drops. North Atlantic Seed Co., a US retailer of the breeder, carries roughly 150 In House releases sorted into Gold Packs, Black Packs, annual drop series for 2024, 2025 and 2026, a Last Chance group and a small regular photoperiod set. Because releases are sold as drops, a given cross can leave circulation once a run sells through.
Slurricane
Slurricane is the breeder's signature cultivar, a feminized cross of Do-Si-Dos and Purple Punch. It is the release that carried the In House name into wide commercial circulation, and flower, hash and concentrates sold under the Slurricane name across licensed markets trace back to it.
Other releases
In House is credited as the original breeder of Dolato, Jelly Breath, Apricot and Black Cherry Punch alongside Slurricane. Documented lineages include Sugar Cane, a Platinum and Slurricane cross; Black Cherry Punch, from Black Cherry Pie and Purple Punch; and Jelly Breath S1, a selfed line taken from the North Cascade cut of Jelly Breath. Platinum Kush Breath and Pancakes also circulate under the breeder's name.
Reach and distribution
Retailers describe the work in terms of bag appeal and bold terpene profiles, and In House genetics turn up in clone libraries, commercial flower and crosses made by other breeders. US seed banks carrying the line include Seeds Here Now and North Atlantic Seed Co. The breeder's Instagram account is @inhousegenetics.official.
