Start Now!

Designed for alums of my Grow course, it's the advanced class students have been asking for. The Advanced Grow class happens concurrently with the Grow course so returning students have access to both sets of live Q & A sessions AND allows us to spend time on four deeper topics. Each topic will have it's own live zoom class for learning the techniques of: cloning, advanced foliar applications and breeding. The fourth topic will be the common thread throughout the six months, venturing into Cannabis as plant ally.

Included in this course:

⭐️ Four live online classes.

⭐️ 12 pack of regular seeds, 3 each of: Queen of Hope, Blackberry Kush, Blueberry Muffin & Pinkleberry Lemonade

⭐️ Automatic enrollment in the 2025 Grow Course Cohort

⭐️ Invitation to join any of the In Person Grow sessions on the land at Heartstone.

Tammi Sweet

Tammi Sweet loves to teach. It’s her superpower. She has a magical ability to connect with almost anyone when teaching and help them understand complex material. For over 30 years, Tammi has shared her gift of teaching at various colleges, massage schools and herbal schools throughout the country. Her background in physiology makes her an invaluable resource to developing herbalists, massage therapists and anyone wanting to care for their bodies alike, who want to deepen their foundational knowledge of the body. In addition to her physiology expertise, Tammi is also a practitioner and teacher of herbal medicine. She is deeply influenced by her studies with accomplished herbalists, including Rosemary Gladstar, Pam Montgomery, Brooke Medicine Eagle,Tom Brown, Jr. and especially Stephen Buhner’s pioneering work on the heart as an organ of perception. In 2007, Tammi set out to “combine all the things I love into one curriculum and teach whatever I wanted in ways that made sense--on my own terms.” So she and her partner Kris Miller launched the Heartstone Center for Earth Essentials. At Heartstone, Tammi and Kris run two residential programs, an Herbal Apprenticeship and Journey of the Heart. They also offer online courses that integrate physiology and plant medicine with Tammi’s love of teaching, such as her signature course Anatomy & Physiology for Herbalists. Tammi’s vision is for Heartstone to co-create a space with the land, where people can come "home," take refuge and find the sacred both on the land and within themselves and facilitate healing. When not teaching, Tammi loves to spend time alone and ‘recharge’ by exploring the land, writing, and hiking.
