Shipping is expensive, and it gets more expensive almost every year. We are not going to pretend otherwise. What we can tell you is that we work hard to find the most reliable and affordable way to get your order to you, and we pass along free shipping wherever it makes sense.
Free shipping on any order with two or more items. The one exception is bulk items, meaning the large or heavy products that have to move by freight or oversized parcel. If your cart qualifies, free shipping is applied automatically at checkout.
Most stores set free shipping at a dollar threshold. That works when you sell light things like clothing. We don't. We ship soil, amendments, and heavy real goods that are expensive and awkward to move, so a dollar minimum doesn't reflect what shipping actually costs us.
We are a small business with no outside financial backing, and we are not Amazon. We manufacture, pack, and ship everything in house so we can control quality, which means real people picking, boxing, taping, and labeling every order, and that means real jobs. When we ship a single item for free, the only way to cover it is to raise prices across the board, and we would rather not do that. Asking for two or more items on free orders lets us keep prices lower for everyone and keep shipping sustainable. We hate high shipping costs as much as you do, and this is the fairest way we have found to keep them down.
Every product page shows an estimated delivery window based on current fulfillment and carrier schedules, so you know what to expect before you buy.
Free on eligible orders with two or more items. We select the carrier and method.
Standard ground service.
Order by noon MT on a business day and it ships the same day. Order after noon or on a weekend and it ships the next business day. If we miss that, we refund your shipping charge.
Faster transit with the same handling guarantee as Rushed Out the Door.
The fastest option we offer.
Bring your order confirmation and a valid ID.
For large or heavy orders.
For large or heavy orders, faster transit.
If a Rushed Out the Door or Get It Fast order does not ship on time, we refund your shipping charge. You do not need to ask. Business days are Monday to Friday, not counting holidays. The guarantee covers when your order leaves our building. Transit times are carrier estimates.
We ship with FedEx, UPS, and USPS, and we pick the carrier that gets your order to you reliably at the best cost. We cannot guarantee a specific carrier unless you arrange it with us ahead of time.
Orders to PO Boxes often cost more and usually do not qualify for free shipping. Use a physical address to avoid delays and added fees.
We ship to Alaska, Hawaii, Puerto Rico, Guam, the Northern Mariana Islands, and the US Virgin Islands. Free shipping generally does not apply to large or bulky items going to these destinations, though Hawaii and Alaska have more flexibility depending on carrier policy. Rates are quoted at checkout or on request.
We ship select items to Canada. Canadian customers need to choose "UPS Standard Shipping to Canada" at checkout so your order clears customs cleanly and you avoid surprise brokerage fees. Orders placed with other methods can be delayed or rejected at the border.
Some products ship directly from our vendor partners and show their own estimated ship dates on the product page. For questions about these, reach out through our contact page or the chat button on any page.
Freight orders arrive on pallets by box truck or semi. We assume you need liftgate service unless you tell us otherwise.
Inspect every freight shipment before you sign. Count the packages and check for damage. Signing the delivery receipt confirms the order arrived complete and undamaged, so note any problem on the receipt before you sign it.
Full truckload (FTL) orders are custom quoted after checkout based on your location, order volume, and how the truck will be unloaded.
We email tracking as soon as your order ships. If it does not arrive, check buildasoil.aftership.com with your order details, or reach out through our contact page.
This optional add-on at checkout covers your shipment against loss, theft, and damage, and we fast-track those claims for replacement or resolution. Even with protection, photos and documentation help us move carrier claims along faster.
Send all claims through our contact page. We do not process claims by phone.
Please report damaged or missing items as soon as you open your order, and no later than 30 days after delivery. Include:
Hold onto the packaging and any damaged items until the claim is resolved, since carriers may require an inspection.
We help with every carrier claim we can. But once an order is in the carrier's hands, we cannot control delays, damage, or misdelivery, and the carrier makes the final call on claims.
BuildASoil Mineral Kit - (For Peatmoss) - 27 lb Mineral Mix - Mixes into 9 Cubic Feet of Soil (1/3 Yard) is backordered and will ship as soon as it is back in stock.
Mineral Kit for peat moss
Canadian sphagnum peat is acidic straight out of the bale. This kit brings it into range and loads it with calcium, sulfur, and trace minerals: basalt, gypsum, and oyster shell flour in a 2 to 1 to 1 ratio. Mix it in with the Nutrient Kit and your base, and you have built a living soil.
Start here
This kit is built for new soil. Peat or coco coir, same kit, same rate.
A new batch built on peat moss
You are mixing fresh soil from scratch with Canadian sphagnum peat as the base. The oyster shell flour in here is sized to lime that peat.
A custom mix with coco coir
Living soil is designed around peat moss, and it performs best that way. Many growers build their own mix with coco, often half coco and half peat. This kit works there too, at the same 4 cups per cubic foot.
Re-amending used soil
Soil you already built was limed when you made it. Re-amending calls for a lighter mineral mix, not a second full liming.
What is in it
Every bag is mixed to the same recipe. Half of it is rock dust for the long game, and half of it is calcium in two forms to balance the peat.
2parts
BuildASoil Basalt
Trace minerals
Our favorite rock dust. A broad spread of trace elements that weather out slowly over the life of the soil. Highly paramagnetic.
1part
Gypsum
Calcium and sulfur
Calcium and sulfur without pushing pH, so it adds calcium on top of the liming instead of more liming.
1part
Oyster shell flour
Calcium and liming
Calcium carbonate. This is the part that lifts the pH of the peat and adds available calcium as it does.
By volume. A full bag is half basalt, a quarter gypsum, and a quarter oyster shell flour.
Why oyster shell
Most peat-based mixes are limed with dolomite because it is cheap and it moves pH. The problem is that dolomite carries calcium and magnesium together, and the two release at different rates. Once it is in the soil, the calcium to magnesium balance is out of your hands.
We lime with oyster shell flour instead and add calcium a second way with gypsum. You know exactly what went in, and if a soil test later shows magnesium running short, you can add it on its own at the rate you need.
Two bags, one soil
Minerals alone do not make a soil. You need the Nutrient Kit too. Both go into the same base at mixing time.
Your base
Peat, aeration, compost
The body of the soil. You source this or pick it up locally.
Mineral Kit
You are here
Brings the peat into range and adds calcium, sulfur, and trace minerals.
Nutrient Kit
Clackamas Coot style
The meals and organic inputs that feed the soil life and the plant.
Why two bags instead of one. Rock dust holds natural moisture. Packed in with raw nutrient meals, that moisture would start working on them in the bag. Keeping them separate means both arrive the way they left us.
How much
Use 4 cups per cubic foot of finished soil, or about a half cup per gallon. Pick the bag that matches the batch you are building.
| Size | About | Mixes into |
|---|---|---|
| 27 lb | 37 cups | 9 cubic feet (1/3 yard) |
| 40 lb | 55 cups | 14 cubic feet (1/2 yard) |
| 80 lb | 110 cups | 27 cubic feet (1 yard) |
| 2,000 lb tote | Bulk | 25 cubic yards |
Questions
Yes. We focus on peat moss because that is how living soil is designed, and a living soil built on coco is not quite as good. Many growers still make their own custom mix, often half coco and half peat, and this kit works for that. Use the same 4 cups per cubic foot.
No. Your soil was limed when you built it. Re-amending calls for a lighter mineral mix, which you will find with our other soil building kits.
Yes, if you are building a complete soil. This kit covers the minerals. The Nutrient Kit covers the meals and organic inputs. The Complete Soil Building Kit gets you both for less than buying them separately.
Rock dust carries natural moisture. Bagging it with raw nutrient meals would let that moisture start working on them before they ever reach your soil.

Massive diffrence in product. The 1 thing forgot when making own soil last time, had fight little magnesium deficiency & phosphorous deficiency. Zero deficiencies this time.
Great product
The best hands down
If im growing in it 2 cups to start, and 2 cups each month unless its near transition a week before. Its just simple and the spectrum is covered!
My plants are exploding with vibrant new life !!
