Delivery and Shipping

Shipping Policy

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.

Why two items and not a dollar amount?

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.

Carriers

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.

PO Boxes

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.

Outside the Continental US

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.

Canada

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.

Vendor-Fulfilled Items

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 Shipments

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 Truckloads

Full truckload (FTL) orders are custom quoted after checkout based on your location, order volume, and how the truck will be unloaded.

  • Let us know if you have a dock, forklift, or other unloading equipment.
  • Tell us if you need liftgate or manual unload service.
  • Reach out through our contact page ahead of time for an FTL quote.
Order Tracking

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.

Shipping Protection

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.

Claims

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:

  • A description of the issue
  • Photos of the box as it arrived and all packaging
  • Photos or video of the items you received, including any damage
  • A photo of the packing slip

Hold onto the packaging and any damaged items until the claim is resolved, since carriers may require an inspection.

Claim deadlines

  • Damage or missing items: within 30 days of delivery
  • Incorrect products: within 60 days of shipment
  • Lost or misdelivered packages: within 60 days of shipment
Once Your Order Leaves Our Facility

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.

Description

Your seedlings and clones deserve the best start possible. Too often, growers struggle with seedling soils that dry out too quickly, stay too wet, or simply don’t provide the right nutrition. A poor start can mean weak roots, slow growth, and ultimately, plants that never reach their full potential.

That’s why we created Heady Starts Seedling Soil, a carefully crafted blend designed for perfect moisture retention, aeration, and nutrition. We started from scratch, sourcing only the highest-quality ingredients, including premium Canadian Sphagnum Peat moss and organic, non-buffered Char-Coir coco coir. With 33% perlite, this mix provides unbeatable texture, ensuring your seedlings and clones develop vigorous root systems.

 What Makes Heady Starts Different?

✅ The Perfect Blend of Texture & Nutrition

  • Canadian Sphagnum Peat moss – High-quality peat for moisture retention and structure.
  • Organic Char-Coir Coco Coir – Premium non-buffered coco for balanced aeration.
  • 33% Small Perlite – Provides perfect drainage and prevents compaction.
  • BuildASoil Worm Castings – Nutrient-rich organic matter for strong plant development.
  • BuildASoil Basalt Volcanic Rock Dust – Packed with trace minerals for plant health.
  • Montana Grow High Available Silica Volcanic Rock Dust – Supports strong cell walls and resilience.
  • Charged Bio Char – Helps retain nutrients and boosts soil microbiology.
  • BuildASoil Mustard Seed Meal – Naturally biofumigates to suppress pathogens and larvae.
  • High Phosphorus Rice Bran – A powerful source of slow-release organic nutrients.
  • Kelp Meal – Provides natural growth hormones and essential minerals and soil structure.
  • Diamond K Gypsum – Enhances soil structure and provides calcium and sulfur.
  • Oyster Shell Flour – Adds long-lasting calcium to balance pH.
  • Calcium Silicate – Strengthens plant cell walls for improved vigor.
  • Camelina Meal – Rich in proteins and nutrients for healthy microbial activity.
