Why BuildASoil?
We didn't set out to be the biggest soil company. Just the best one. Here's what happened when people with no ties to us put that to the test.
Ranked #1 of 26 Bagged Soils
Lab tested, grown out, and scored across nutrients, soil structure, and real plant performance. BuildASoil 3.0 took the top spot. See exactly why.
We had no involvement in this review. Know Before You Grow purchased our soil at retail, tested it alongside 25 competitors, and published their findings without our knowledge. We found out when the video went live. This wasn't a sponsorship, a partnership, or a paid placement. We didn't ask for it, and we didn't pay for it.
Jeremy mixing soil by hand in the early days
Thirteen years ago it was just me, a tarp, and a shovel in my garage in Colorado. I never thought we'd end up ranked right next to the biggest soil companies out there. Truth is, making soil wasn't even the goal when we started. But once we did, our only goal became making the best in the world.
Here's the part most companies skip: we mix the soil once, then let it rest at the perfect moisture so it can compost together. Once it has, we remix and re-moisten it before it ever hits a bag. Yes, it costs more, but you keep it forever, and the ingredients and the care it takes to do this right just cost more. We don't cut that corner.
So when an outside crew with zero ties to us tested the whole field and landed on the same thing we already knew, man, that hit different. We're still the little guys going up against the big corporations, and the fact that you discovered us is what keeps us stoked to do this.
Why our 3.0 is different
Real living soil, built over time to keep forever. Not mixed once and bagged.
Every ingredient, sourced and tested before it ever goes in the bag.
Each small batch is mixed once, composted, then mixed again before bagging.
Every batch is lab tested to guarantee quality and consistency.
Every ingredient sourced and tested by BuildASoil, so you can trust it.
Built with minerals and volcanic pumice to last a lifetime. Re-amend and reuse.
We won “Soil Wars.” Not even close.
Virginia hemp farmer York River Cannabis grew identical plants in 11 different bagged soils, side by side, across an entire season. Twenty-one episodes of documented results. We didn't sponsor it, didn't pay for placement, and didn't know about it ahead of time. Here's how it ended.
BuildASoil swept 1st and 2nd place.
Watch the winner reveal, 11 bags ranked
Eleven soils. One season. Identical plants in identical conditions. The results weren't even close, and we didn't pay a dollar to make it happen.
The independent test that speaks for itself
Real growers. Real results.
Independent labs put us #1. Here's what the people actually growing in our soil say after full seasons and years of running BuildASoil 3.0.
