Grow it yourself, one plant at a time.
Soil, water, sowing and harvest for medicinal and useful plants, written plainly with exact numbers and tested by the people who grow them.

Pick what you want to grow, keep or learn.
Medicinal plants
What each plant does, how to grow it, and how to turn it into something usable.
40 guidesFood crops, orchards and preserving
Growing what you eat, and keeping the harvest: vegetables, grain, fruit, the trees that carry it, and drying, fermenting and storing it.
18 guidesExtraction and processing
Getting the active compounds out, and what each method costs you.
9 guidesCompounds and science
What the actives actually are, and how they work once they are in you.
12 guidesLand, water and livestock
The ground it grows in and the systems around it: soil, water, fences, animals.
9 guidesAll guides
Every guide in one searchable list, plant by plant.
88 guidesKnowledge people can use on their own.
We teach growing, and extraction, plant by plant, from the basics anyone can start with to the methods used at industrial scale.
Self sufficiency
Our goal is to give back what we have learned by teaching growing methods on as many plants as we can, so people have the knowledge they need to take care of themselves.
Explained so you can trust it
Every complex topic comes with an example from everyday life, plus exact instructions, numbers, equipment and processes. The point is to understand it, not to memorize it.
Old knowledge, modern tools
We read old texts from around the world next to modern soil and nutrient chemistry. Regenerative growing combined with modern equipment is where we think agriculture is going.
Free to read
Simplified versions of everything we teach are free here as articles, because we want people to have access to this information.
What sits behind every guide.
The guides come from systems we have built and run, not from reading about them.
Automated irrigation
An irrigation system we built measures soil moisture on its own, syncs with weather data so it skips watering when rain is coming, and is controlled from a phone.
Propagation at scale
Automated systems we built and ran propagated thousands of cuttings a week, using aquaponics and aeroponics, and breeding work produced new plant varieties.
Light and air, measured
Greenhouses and indoor grows tuned by vapor pressure deficit (how hard the air pulls water out of the leaves), PPFD (the light that actually reaches the leaves) and lux.
Soil and tissue chemistry
Soil nutrient testing and plant tissue analysis, nutrient uptake, the root microbiome, and substrates from pumice and peat to coco, compost and biochar.
Land and water
Reverse osmosis systems, natural irrigation, raised beds from whatever materials are on hand, and terraces cut with equipment we operate ourselves.
Growing for extraction
Part of the work is aimed at extraction: which growing methods raise yields, and how the nutrients a plant gets change the amount of its compounds.



How the work got here.
We are a family farm in Kerrville, Texas, where everyone pitches in. About five years of growing and extracting medicinal plants, and each guide comes out of that hands-on work.
Plants and soil first
The work began with learning how plants take up nutrients and how a root meets the soil around it.
Water that thinks for itself
Irrigation moved from a hose to sensors, weather data and zone watering that runs without anyone standing there.
Propagation at scale
Cloning and propagation grew into automated systems, with aquaponics, aeroponics and breeding.
Light, air and land
Greenhouses and indoor grows were built and tuned, and land was cleared and terraced.
Teaching what works
The goal today is to teach the methods on as many plants as possible, one careful guide at a time.

Start with these.
A few places to begin. Every guide is free to read.
Ebooks and courses are coming.
Each one follows one plant at a time.
Our growing guides, as full books.
Full-length books, one plant each, with every schedule and figure in one place.
- Growing Chamomile
- More plants after it
Plant-by-plant courses, in our Skool community.
A season with one plant, taught in short lessons with a checklist for each step.
- Lesson by lesson
