The BuildASoil Way

Feed the soil, not the plant. Build it once, and let the biology do the work.

The whole idea behind living organic soil is simple: instead of feeding your plant with a steady drip of water-soluble nutrients out of bottles, you build a living soil that feeds the plant for you. Get the soil right, and the guessing mostly disappears.

The modern way is to make NPK and micronutrients plant-available through liquid feeding, where the pH of your nutrient supply heavily affects the outcome. That’s the “feeding the plant” paradigm. The BuildASoil way is the opposite: combine premium, tested compost with diverse mineral inputs and let biology do the work. We want it all in the soil, available on demand, so the plant takes exactly what it needs, when it needs it. A living soil food web is the engine, and a healthy one grows stronger, more resilient, better-tasting plants while you do less.

The best part: indoors, you have a blank canvas. You can literally build the best soil possible and grow in it for years. This guide is written around vegetables and medicinal herbs, but it works for most fast annual flowering plants, the same principles apply across the board. Read through it, and you’ll start to “get it” and build your own system that fits your space and your goals.

Where This Came From

I think it’s important you know the roots of this, because the BuildASoil way wasn’t invented in a marketing meeting. It came out of a real community, during a specific moment in time.

Indoor no-till living organic soil, grown the way we teach it, was figured out collectively on the grow forums. It started on ICMag and continued on Grasscity, RollItUp, and others, growers trading recipes, running experiments, and sharing what actually worked, post by post, grow by grow.

The thread that started it all for me was Gascanastan’s “Living Organic Soil from Start Through Recycling.” Before that, “organic” growing mostly meant bottled organic nutrients, or small containers with layered amendments. It wasn’t yet a real method. The community changed that by paying attention to nature: the forest mulches itself from the top down, and the forest floor has real depth and volume.

At first, recycling your soil meant dumping it onto a tarp and re-amending it by hand between every run. Then growers like BlueJayWay started running bigger containers and simply planting back in without dumping and re-amending, and it worked. Others jumped in, and over the years we all learned a ton together, including the arguments that were half the fun, like whether you should cook your soil for two weeks first or plant directly into it.

Compost tea was huge in that era, and there were a lot of myths flying around, along with plenty of expensive courses and dogma about the “right” way to do it. MicrobeMan (Tim Wilson) kept it real and BS-free. He shared his protocols for actively aerated compost tea for free, grounded in his own microscope work rather than hearsay or hype. Coots was the same way: no dogma, just what actually worked. That commitment to real observation over expensive theory is a big part of what made this community trustworthy.

And I learned this from the best. Clackamas Coots was my mentor, the man behind so much of the foundational thinking, including a truth I’ve never forgotten: when you make great compost, the actual grow is almost a non-event. Gascanastan lit the fuse and shared freely. After the fallout on ICMag, I helped start the original LivingOrganicSoil forums and stayed active for years, though I was always clear my real goal was BuildASoil. Eventually BuildASoil took all my time, so I handed the domain and the forums over entirely to Gascanastan and MissGreenDreams, and the rest is history.

This community didn’t just stay online, either. Through relationships built on these forums, we helped start some of the very first commercial living soil grows in the country. My friend PermaLos, who I met on ICMag, went on to become a grower and consultant for large-scale commercial no-till operations nationwide, and helped start Green Life Productions in Nevada, one of the first, and still going strong today.

It was built alongside countless others, Scrappy4, MissGreenDreams, DARC MIND, Desert Dan, Neo420, Spurr, Cann, verdantgreen, heady Blunts, silversurferOG, and so many more, plus everyone who lurked, learned, and grew right alongside us. There was drama, there were splits, people came and went and forums rose and faded, that’s how real communities go. But the soil outlasted all of it.

That’s the soil BuildASoil grew out of. We didn’t invent this. We learned it in that community, helped push it forward, and helped grow the living soil community into what it is today. We’re connected to that lineage, not bandwagoning on a trend, and every time we improve the method, we’re adding to something a lot of people built together.

Continuous credit to Clackamas Coots, Gascanastan, MicrobeMan, BlueJayWay, and every grower who came before us and shared what they knew.

The Core of It (6 Simple Rules)

If you remember nothing else, remember these.

1. Don’t try to grow a plant, build a soil that grows it for you. Use premium inputs, keep the soil alive and moist, and treat it like a pet. Put more in than you take out and it lasts forever, getting better over time.
2. Use premium compost or worm castings, ideally homemade. This is the heart of living soil. Make your own if you can (you’d be surprised how little space it takes), or buy a genuinely good source. Quality compost is where the magic comes from.
3. Don’t go back to bottled nutrients. Even “organic” bottles often aren’t as good as your own living soil. Get the soil right and your garden does more of the work for you. Focus on building soil, not feeding plants.
4. Be picky about your ingredients. The “organic” label doesn’t guarantee quality. Know what’s actually in your inputs, good ingredients in means good results out.
5. Always mulch. If you skip the mulch layer, you’re missing the boat. It protects the soil, feeds the biology, and keeps everything alive on the surface where the action happens.
6. Keep it alive and moist. The biology needs consistent moisture to work. Never let your soil, or your topdressing, dry out and go dormant.

What Makes Living Soil Different

A bag of potting mix is mostly an inert sponge, it holds water and a little fertilizer, and once that’s used up, it’s done. Living organic soil is the opposite: it’s a complete, self-sustaining ecosystem. It holds and cycles nutrients, builds long-term fertility, and feeds your plant on demand through the partnership between roots and soil biology, a relationship nature has been refining for hundreds of millions of years.

That’s why it matters that it’s alive. The microbes are the real engine of plant health, turning compost, minerals, and mulch into plant-ready nutrition exactly when your plant calls for it. Instead of you controlling every variable, you’re tending an ecosystem and letting it do what it already knows how to do. The result is healthier, more resilient plants, better flavor and aroma, and a whole lot less daily fuss.

And because you build it from scratch with quality compost and diverse mineral inputs, instead of relying on water-soluble shortcuts, you set the ceiling on everything downstream before you ever plant. Start with the best, and the rest gets easy.

Think Farmer, Not Scientist. Think Alive, Not Sterile.

If you’re anything like me (and if you’re reading this deep on an organic soil website, you probably are), you’ve noticed how our culture has long feared microbes. I avoid hand sanitizer and unnecessary antibiotics for the same reason, I believe in working with the microbiome, not against it.

For years, people said bringing raised-bed-style organic growing indoors just wouldn’t work. They claimed you’d get pests, diseases, and poor results, and the hydroponics industry pushed sterile systems as the only way forward. Some instructors even taught people to “sterilize” their soil by baking it in the oven.

But the truth is the opposite. You can grow the same way you’d grow your grandmother’s tomatoes and get better results, even indoors. Living soil growers now have solutions for nearly every challenge, all by mimicking nature instead of fighting it. It’s no surprise living soil is quickly becoming the most popular way to grow for home growers across the country.

Tying It All Together

When growing, the most important thing isn’t any single product, it’s the mindset. Build a living soil that feeds your plants, keep it alive and moist, mulch it, and observe. Put more in than you take out, and the soil rewards you season after season, getting better every round.

You don’t need magic bottles. You need living soil that does the work for you. Start simple with a water-only setup, trust the soil, and let it teach you. Observe, adjust, and grow, you’re going to be glad you did.
