FedEx Freight (Economy or Priority)
Large or heavy orders that qualify for freight shipping will be offered these options. All freight ships via FedEx Freight unless otherwise arranged. If you require a non-liftgate delivery (e.g. dock or forklift available), please contact us in advance.
We primarily ship with FedEx, UPS, and USPS. If you need a specific carrier for a specific shipping address, please reach out to us by phone at 855-877-7645, or send us an email to support@buildasoil.com, which will create a customer support ticket. You also have the option of submitting a ticket through the support.buildasoil.com site.
Orders addressed to PO Boxes often incur additional costs and are ineligible for free shipping. To avoid delays or fees, we recommend using a physical shipping address whenever possible.
We do ship to Alaska, Hawaii, Puerto Rico, Guam, the U.S. Virgin Islands, and other U.S. territories.
Free shipping does not apply to most large or bulky items sent to these locations. Standard or custom rates will be calculated at checkout. Contact us if you need a freight quote for outlying areas.
Some products ship directly from our vendor partners. These will display accurate estimated ship dates on their product pages. Any concerns or delays with these items should be directed to support@buildasoil.com.
Freight shipping involves delivery of pallets via box trucks or semi-trailers.
By default, all freight is assumed to require liftgate service. If you do not need a liftgate, please notify us prior to shipment.
Inspect your freight order before signing the delivery receipt.
Count the number of packages and check for visible or concealed damage. Do not sign unless everything is accounted for and undamaged. Signing a receipt waives the right to claim missing or damaged freight unless noted at delivery.
Tracking information will be emailed to the address on file once the order ships.
If you do not see the tracking email, visit https://buildasoil.aftership.com/ to locate your order using your email and order number. You may also contact support@buildasoil.com for assistance.
You can add BuildASoil Shipping Protection at checkout. This low-cost option insures your order against loss, theft, and damage.
If something goes wrong during transit, your replacement order will be fast-tracked through our claims system.
Even when protection is purchased, we request that you submit photos, videos, and any supporting evidence of the issue. This allows us to file formal claims with carriers and ensure the long-term success of our shipping network.
All claims must be made via support@buildasoil.com.
We do not accept claim submissions via phone.
To process your claim, we require the following:
A clear description of the issue
Photos or videos documenting damage, missing items, or incorrect products
Images of packaging, shipping labels, and box condition if relevant
Do not discard any shipping materials or products involved in the claim—carriers may require inspection.
Claim Deadlines:
Visible or Concealed Damage / Missing Items: Report within 5 business days of delivery
Incorrect Products: Report within 30 days of delivery
Lost Packages or Incorrect Delivery: Report within 30 days of shipment date
Once an order has left our facility, BuildASoil is not responsible for carrier-related issues such as delays, misroutes, or mishandled deliveries.
We will support claims to the best of our ability, but the final resolution is subject to carrier approval.
Additionally, we maintain zero tolerance for mistreatment of delivery drivers, delivery dispatchers, or anyone with the shipping/freight carrier. Any reported conflict resulting in a failed delivery will result in the order being refunded, minus the cost of shipping and a 15% restocking fee.
Korean natural farming, or KNF, is a style of gardening and farming created by Master Cho. There are several inputs that it utilizes, such as indigenous microorganisms, fermented products, and lactic acid bacteria serum.
By providing optimal plant nutrition, KNF reduces the need for pesticides and chemical fixes. As healthy plants are able to resist pests, disease, mold, etc. by improving the soil, KNF grown plants thrive even when environmental conditions are poor.

Bought this twice now. I use it when I use JLF or FPEs or anything that might have some "bad" microbes in it. Last a long time. I dig it
Great option for anyone wanting to explore KNF or if in need/want of something not on deck this is perfect as well. Really actives soil microbiology and also works great as pest repellent. A little swig of OHN or in shake/smoothie is solid as well ;). Kiefr goat milk being base liquid with flax milk then all other goodies
Really gets the ladies perky. Highly recommended for any KNF growers.
Wow awesome
