In House Genetics is a two-man outfit in Snohomish, Washington, with more than twenty years of growing behind them and a backbone plant that explains everything since: Platinum, their UW Hashplant and Permafrost cross, the frost engine they built the catalog on.

Slurricane is the famous product of it, Do-Si-Dos over Purple Punch, and the numbered phenos out of that line became fixtures in gardens worldwide. Small team, limited drops, ruthless selection. The crosses below carry In House work.
