We are brothers, Colorado natives, and 3rd generation farmers. Our involvement with hemp began as soon as it was legalized in Colorado.  What started off as a pursuit to perfect large scale industrial hemp farming, has now broadened to include specialized genetics and high-yielding feminized seeds. Driven by a passion for creating the best genetics while making hemp affordable to produce whether you are growing an acre or a thousand. 

In mid-2018, Mile High partnered with Tritium 3H. Standing behind the Tritium 3H brand is more than 20 years of Certified seed production experience in multiple hybrid crops, serving international markets in Canada, USA, Europe, South America and Australia.  The Tritium partnership merges Mile High’s proven genetic portfolio with T3H’s international asset base and extensive experience in large scale hybrid crop production. Bringing all of this together has resulted in top quality feminized hemp seeds at a price that is affordable for all!
