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.

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. Questions about these go to support@buildasoil.com.
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 email support@buildasoil.com.
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 to support@buildasoil.com. We do not process claims by phone.
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.

Logan Labs, one complete package
Every test a living soil grower needs to re-amend accurately, in one package, for $115 with prepaid postage to the lab. No configuration to get wrong. No second invoice. You do not need to know anything about soil testing to order it.
Nothing to learn right now
Four steps. Two of them are ours, two are yours, and yours add up to about ten minutes and one trip to the carrier.
Complete instructions arrive by email, along with a prepaid shipping label and a submission form already filled out with the right tests selected. They come separately from your order confirmation, so check spam if nothing has landed within a day.
UsTwo cups of soil from a few spots in the same bed, into a bag. Our guide shows you exactly where to pull from and why it matters.
You, about ten minutesSample and form in a box, prepaid label on the outside, hand it to the carrier. That is your entire job done.
You, one tripAbout a week at the lab, then the report emails straight to you and to us at the same time. We follow up with free guides for reading it, and you can buy a written interpretation if you would rather have a person do it.
UsYou do not need to understand any of this before you order. Everything below explains what is in the package and why, and it is here for people who want to know. If you would rather just get your soil tested, add it to the cart and read the emails when they come.
What this price covers: the lab work, the postage, the paperwork, and the guides for reading your results. Reading the report is either free with our interpretation tool or a paid add on if you want a person to do it. We keep that separate rather than bundling it, because most growers do not need it.
Want to read ahead? Every guide we send is free and public at our soil test guides page.
Why three tests and not one
Growers usually pick one test, get half an answer, and then make a decision that needed the other half. These are the two questions, and this package covers both.
Question one
What are my plants drinking right now?
The saturated paste measures what is dissolved in the soil water, which is what roots actually take up today. Every potting soil should be read this way. It is the test that tells you whether something is available, not just present.
Question two
What is held in reserve, and how much do I add back?
Re-amending by volume is math, and that math runs off your cation exchange capacity. Get the CEC wrong and every amendment number you calculate afterward is wrong with it. The Mehlich 3 and the AA 8.2 together are what make the CEC honest.
The reason we made AA 8.2 mandatory
If you built your soil with oyster shell flour, or you have top dressed with a liming mineral, there is very likely free calcium sitting in it. Here is what that does to a standard test, and why we no longer sell the standard test on its own.
Starts here
Free calcium is sitting in the mix
Oyster shell flour is calcium carbonate. It is coarse and it dissolves slowly, so undissolved particles stay in the soil for a long time, especially in a fresh mix or after a recent top dress.
The extraction
Mehlich 3 dissolves it and counts it
Mehlich 3 is an acid extractant at roughly pH 2.5. It does not care what your soil pH reads. It dissolves those carbonate particles and reports that calcium as though it had been sitting on an exchange site all along.
The knock on
Your CEC inflates, and everything else deflates
CEC is summed from the cations on the report. An inflated calcium figure inflates the whole exchange capacity, so every other base saturation percentage gets divided by a number that is too big and reads lower than it really is.
What it costs you
You amend against fiction
Potassium looks short when it is not. Magnesium looks short when it is not. You mix in amendments you did not need, at rates calculated from a capacity your soil does not have, and you pay for all of it.
The AA 8.2 is buffered at pH 8.2, so it leaves the free carbonate alone and returns your real exchangeable calcium. Swap that figure in, recalculate the CEC, and the rest of the math holds.
The package
One package covers one sample. We are happy to run as many reports as you want, it is simply the same price each time. If you are a commercial operation pulling a lot of samples, you will save real money going direct to Logan Labs, because you can ship every sample in one bag instead of paying our per package price on each. For a home grower with a bed or two, working with us is the simple route.
Buying direct
They sell every one of these tests on its own, they publish their pricing, and they are genuinely helpful on the phone. Go do your own research over there before you buy from us. We would rather you did.
We charge a little more than the tests cost on their own. That difference covers your prepaid postage to Ohio and a submission form that shows up already filled out with the right tests selected. Once you add a box and postage of your own, the two routes land close together, and what you are really paying us for is not having to learn the lab's ordering system to get a usable answer.
We used to sell this package three different ways and let you assemble it yourself. We stopped, because on a potting soil the cheaper configurations produce confident numbers that are wrong, and we would rather sell one package that gives a real answer than three that give you something to misread.
If your situation calls for a different combination of tests, or you are a professional pulling a lot of samples at once, the lab is the right place to buy it. Not us.
After your report lands
This package is the lab work. It is not an interpretation, and we sell those separately now so nobody ends up waiting on an answer they did not know they had to buy.
Plenty of growers run their own report through our free tool, which does the same math we run internally. Plenty of others would rather hand it to somebody who reads these every day. Both are fine.
Do it yourself, free. Drop the PDF Logan sends you into our interpretation tool and it returns an amendment plan. Your Complete test comes back with the Mehlich 3 and the AA 8.2 on the same PDF, so it is one file and one upload. No account, and your file never leaves your browser.
Have it read for you. Paid interpretation with amendment recommendations, sold separately. We work with more than one interpreter, so pricing and turnaround depend on who reads it. Current options are listed on their own page.

Questions we actually get
If you built your soil with oyster shell flour or any liming mineral, and nearly every living soil recipe does, then yes. Without it your calcium reads high, your CEC reads high, and every amendment rate you calculate from that CEC is wrong. We used to sell it as an optional add on and that was a mistake, because the people skipping it were exactly the people who needed it. Now it is simply in the package.
Probably, yes. This is the part that trips people up. Mehlich 3 extracts at roughly pH 2.5, so it dissolves carbonate particles regardless of what your bulk soil pH reads. A mix sitting at 6.4 can still have plenty of undissolved oyster shell in it. Soil pH is not a reliable way to rule out free calcium in a potting mix.
One package covers one sample. We can run as many reports as you like, but each one is the same price, so several beds means several packages. Some growers combine spots from a few beds into one homogeneous sample to keep costs down, which is a fair approach, it just gives you an average instead of a per bed picture. If you are a professional running a lot of samples at once, go direct to Logan Labs. You can put every sample in one bag and ship them together, and you will pay less than you would buying multiple packages from us.
Typically about a week from your order to the final report. Most of that is the lab's queue, which moves with their workload and is not something we control. If it has been noticeably longer, email us and we will chase it.
No. This is the lab work only. Interpretation is sold separately so that it has its own turnaround and nobody is left waiting on something they did not realize they had to order. You can also run your own numbers through our free calculator.
If you are comfortable setting up an account, choosing the right tests, filling in the submission form and paying your own postage, then honestly, go ahead. They publish their pricing and they are good people to deal with. This package exists for growers who want the correct tests selected for them and the shipping handled, not because we are the only way to reach the lab.
