Dominion Potting Soil Blend: Crafted in Collaboration with Duke Diamond

To avoid your premium soil from sitting in a bag, we have devised a limited drop schedule to sell out before bagging. This will ensure that your soil can be fully cooked, tested and then only in a bag for the short trip to your home. This is as close to homemade as we can make it.

  • Drop #2: (Selling Now Based On Inventory)Mixing 9/21/2023, Soil Testing 10/12/2023, Bagging 10/23/2023
  • Only 180 Bags were produced for the first drop. 
  • 270 Bags are being produced for the second drop. 

For over a year, we've been on a passionate journey to craft the ideal soil closely working with the esteemed Duke Diamond of Dominion Seed Company. Every step of our process was influenced by Duke's vision and deep knowledge of plant cultivation. This led us to several test batches, each critically assessed through rigorous lab evaluations, ensuring we were inching closer to Duke's ideal formula. 

Duke, with his lifelong experience, took our blend and grew two complete rounds in it. After aging, we revisited the soil to further assess its potency and balance. The outcome? Our Dominion Potting Soil Blend stood out as the epitome of what Duke would make for himself. It isn’t just another soil; it's a manifestation of Duke's ideal formula and the unmatched quality assurance of BuildASoil.

To emulate the mastery of Duke Diamond in your garden, look no further. Tap in to the Dominion Potting Soil Blend and delve deep into the Dominion Tech. Experience gardening at its pinnacle, and grow as Duke does; with passion, love for the plant, and the Dominion soil.

Notice: A portion of the proceeds will go directly to Duke Diamond. BuildASoil loves supporting fellow growers.


Notice: Limited Batch Production with PRE-ORDER drops only! Each drop will be small batch produced as the nutrient and mineral kit has over 20 items and we want to ensure the highest quality. Once the batch drops, it will be available as pre-order for 30 days until it's done cooking. Soil testing will be taken after day 21 of cooking and added to the drop so you know exactly what you are getting. 

1. Small Batches Only

2. Soil Test on Every Single Batch

3. 30 Days minimum Cook Time before Bagging

4. Initial drops are Cubic Foot Bags ONLY



Full Size Transplants: You can plant directly into the Dominion Potting Soil blend. Make sure the transplant root ball is fully covered with the soil, pressing down gently to avoid any air pockets.

For Fresh Clones or Seedlings: Due to its potency, for younger plants like fresh clones or seedlings, mix the Dominion Potting Soil blend 50% with a starter soil. This ensures a gentler environment for the young roots to establish. Surround the new transplant with this mix, allowing the young plant to grow into the richer soil as it matures.


Store in a cool, dry place away from direct sunlight. If the soil becomes too dry, lightly moisten it with water. Ensure the storage area has good air circulation to prevent mold or mildew.


This soil blend is POTENT. Its rich composition is meant to last, providing you a mix that can be kept and reused for a lifetime. Disclaimer: This Soil is Alive and BuildASoil does not sterilize. Avoid Breathing Dust and Use at your own risk.
