Our Programs

Everything the Foundation does comes back to one question: How do we get KNF knowledge into more hands?

KNF Office Hours

The longest-running KNF education program in English.

Every week, practitioners gather online to learn, share, and troubleshoot KNF methods. Office Hours has been running for years, reaching farmers and gardeners on every continent. Sessions cover everything from basic solution preparation to advanced application strategies. The full archive of recordings is available in our Library — hundreds of hours of practical KNF education, free and searchable.

Monthly Meetings in Hilo

Second Tuesday of every month. Komohana building, Hilo, Hawaii.

The Foundation's local anchor. First hour is education — a deep dive into a KNF solution, led by experienced practitioners. Second hour is a community potluck with one rule: sit with someone you don't know. This is where relationships form, where new practitioners find mentors, and where the local KNF community grows roots. Also available via Zoom for remote members.

Research Program

Proving what practitioners already know — with science.

The Research Committee, chaired by Erik Degunther, runs the member research program. Growers log their grows in one shared format — what they applied, what they saw, what they harvested — so patterns show up across farms and the right questions reach university researchers and funders. KNF has done this before: in 2013–14 Hawaiʻi farmers and UH extension published the core solutions together. Members can take part directly — log a project on your own land, follow the step-by-step guide, and add to the growing record of KNF results.

Certification Program

Setting the standard for KNF practice.

Not all KNF is created equal. The Certification Program establishes clear standards of knowledge and competence for KNF practitioners. Certification verifies that a practitioner understands the principles, can prepare the solutions correctly, and can apply them effectively. For the community, it's a way to identify skilled, knowledgeable people. For the movement, it's a commitment to quality.

Drone Spraying Program

KNF at scale.

One of the barriers to KNF adoption on commercial farms is application — hand-spraying works for a backyard, but what about 10 acres? 50 acres? The Foundation operates a DJI Agras T40 agricultural drone with RTK precision guidance, capable of applying KNF solutions at commercial scale. Based in Hawaii, the drone program demonstrates that KNF methods can work for serious agriculture, not just hobby gardens. We're collecting flight data, application rates, and crop response data to build the case for precision KNF agriculture.

Instructional Video Series

9–12 professional episodes. Every core KNF solution. Start to finish.

Working with video editor Jordan, the Micro-Documentary Committee is producing a documentary-style instructional series that walks viewers through every step of KNF solution preparation — from gathering ingredients to fermentation to application. Each episode covers one core solution: what it does, where to find the ingredients, step-by-step preparation, storage and shelf life, and when and how to apply it. Available to members through the Foundation platform.

Spirit of Master Cho

Ask a question. Get wisdom.

Master Cho Han-kyu's teachings are preserved in years of Office Hours transcripts — thousands of pages of practical KNF knowledge. The Spirit of Master Cho is an AI-powered knowledge base that can search this archive and surface relevant guidance for any KNF question. Type !help followed by your question in the #mastercho channel on chat, and the system finds the most relevant ~4-minute segment from the archive that addresses your question.

Pure KNF Times

Monthly themed content exploring KNF in depth.

Each month, we publish an article diving into a specific aspect of KNF — from Minerals to Fuel to Reproduction to Cleanser. These articles go beyond how-to guides to explore the why behind KNF methods, connecting ancient practice to modern understanding.
