Organic inputs fluctuate. No two batches of a real living soil are ever identical, and any company claiming otherwise is not being straight with you. What does not move is the target range we build to, and every batch lands inside it. We send each one to an independent lab and publish the full result, so you never have to take our word for it.
See every 3.0 batch result →SoiLab, the lab-backed channel run by MySoil, put 26 bagged soils through the same analysis in their Know Before You Grow series. Viewers picked the soils. Nobody sponsored it. They scored each one on smell, look and feel, nutrients and pH, and whether it would actually grow.
We did not pay for this and we did not know the result until they published it. That is the only kind of test worth pointing at.
Tell the calculator about your pots or beds and it does the rest, including finding you the cheapest way to buy it.
Every one of them is in here for a reason, and there is nothing in the bag doing nothing.
Compost, Worm Castings, Canadian Sphagnum Peat Moss, Pumice, Rice Hulls, Chunky Basalt, Fine Basalt, BIG 6 Trace Minerals, Fish Bone Meal, Rice Bran, Kelp Meal, Mustard Seed Meal, Gnarly Barley Organic Pre-Sprouted Seed Flour Blend (organic barley, organic lentil, organic corn), Gypsum, Oyster Shell Flour, Calcium Silicate, Biochar (charged).
Your soil is alive. We don't sterilize our compost or potting soils. The life in the bag is the entire point.
3.0 is our most loaded mix. It's built to carry a plant all the way through flower with nothing but water. That richness is exactly why it isn't right for everything.
You're taking a plant through full term and flowering. You want everything in the bag on day one. No bottles, no feed chart. You're transplanting in from a smaller pot. You've run Super Soil before and liked it.
You're starting seeds or rooting clones. You can plant them straight into 3.0 and they will be fine, they just grow a little slower at first because the soil is so rich. BuildASoil Light is designed for that stage. Houseplants and tropicals want Perma Soil.
We built 3.0 with the water-only grower in mind, and we mean that literally: no bottled liquid nutrients, ever. What it does not mean is that soil volume is free. A big pot holds enough soil to carry a plant all the way through on its own. A small one will run out, and you will want to feed the surface. Here are the two ways people run it.
Put 3.0 in a large enough container, plant into it, and water. That is genuinely it. The bigger the pot, the further the soil carries the plant on its own. Plenty of people grow beautiful plants this way and never top-dress a thing.
Best for: first-timers, bigger containers, keeping it simple.
Same soil, same water-only watering. You build a layered surface at planting and feed it again at the flip to flower, so the biology has food exactly where the feeder roots are. This is our system, and it is what we run in our own tents.
Best for: getting everything the soil is capable of, and no-till.
Amounts below are per plant in a 15 gallon pot, which is the size we recommend starting with. Something clicks at 15 gallons: the soil hits enough volume that the biology really takes over.
Same amounts again, 1/4 cup Craft Blend and about a gallon of BuildAFlower. Premix them, spread over the straw, wiggle it down through the mulch with your hands, and water in. This feeds the plant through the stretch.
Water no more than 5 to 10 percent of your soil volume at a time. In a 15 gallon pot that is roughly 0.75 to 1.5 gallons. Evenly moist, not drenched, not bone dry.
You do not need any of this to grow a good plant in 3.0. This is what we run ourselves, and what most people add on their second order.
The workhorse top-dress. Feeds the soil through the whole run.
From $31
Go on before and during early flower. Replaces bottled bloom products.
From $33
Protects the surface so the soil life stays where the roots are.
From $29Mulch is not an accessory. A bare soil surface dries out and the biology in that top layer dies off, which is exactly the zone your top-dress is trying to feed. Cover it.

The price tag gives a lot of growers pause. It did for me too.
Then I realized this isn't disposable soil. You fill your containers once, re-amend after each cycle, and the soil only gets better as the biology matures. Viewed as a long-term system, it's one of the best investments I've made in my garden.
The soil is incredible, but so is the education. Jeremy and the BuildASoil team don't just sell products, they teach growers 'why' things work, and that's been just as valuable to me as the soil itself.
Don't judge it by the price of a bag. Judge it by where your garden will be two or three years from now. @RegularGrower
