KIS Organics Water Only Soil Mix is a revolutionary "water only" soil mix for all container and raised bed plants. Specially formulated to go from seedling to flower with no inputs but water, our Water Only Soil Mix has all the beneficial biology, nutrients and minerals your plants needs to be happy and healthy for several months. 

Here at KiS, we have made the extra steps to register our soil as fertilizer due to the high level of fertility we have added to the mix.  Our Water Only Soil Mix is registered for organic use in organic production with CDFA and Certified KIND.

We use high quality amendments that work together to create balanced, nutrient dense, biologically active and diverse soil mixes.  The unique combination of minerals and our manipulation of pH have allowed our growers to pass all Heavy Metal testing in numerous states since the original formulation of our recipe.  Any heavy metals present in the formulation have been tested and proven to be relatively unavailable to the plant.

We have taken a lot of time, research and lab testing to perfect our soil mixes. Using high quality amendments that work together we have created balanced, nutrient dense, biologically active and diverse soil mixes with a high ratio of ingredients compared to other soils on the market.   All our mixes are ready to use. 

100% natural and organic ingredients, no synthetic chemicals. Bottled nutrients are not required and there is no need to worry about burning your plants - just plant and water until next harvest.

Additional advantages of our soil mix:

  • We use lab and microscope tested compost and peat to ensure good biological activity.
  • We inoculate our soil mix with additional microorganisms to further increase microbial life and nutrient cycling.
  • No need for further nutrients or fertilizer, saving you tons of money! That being said, we do have an advanced nutrient schedule available on our blog (click here).
  • Can be reused over and over again, with only small amendments between cycles. We have tested and re-amended the soil up to 5 years in indoor beds.
  • Can be used indoors or outdoors, though keep in mind that this soil is alive and there will be some insects and other small organisms in the soil. This is necessary to maintain a healthy soil food web and achieve proper nutrient cycling. You don’t want a sterile soil for organic gardening/growing!

*Not to be considered as a full mycorrhizal application, a separate inoculation of the proper mycorrhiza is recommended, depending on your plant.


We recommend a minimum of 7 gallon containers for maximum benefit on a full cycle plant.

For indoor growing environments, use 60-90 gallons of soil per light. 

Water frequently to keep the soil evenly moist.  For best results, keep soil near field capacity.  To test the soil, take a handful and squeeze it firmly.  If only a drop of two of water comes out, then the soil is near capacity.

When using a moisture meter aim for 80-120 mbar; for best results use Tropf Blumat irrigation.

If you wish to add additional nutrients, please refer to the rest of our product line or use other nutrients at 1/4 of their recommended rate.

NOTE: If growing a larger plant in a small container, you will need to top dress weekly with our KiS Organics Nutrient Pack to achieve optimal plant growth.


All our soil mixes are available in bulk.  Minimum bulk order is 1 cubic yard and we offer discounts on larger quantity orders.

Please note that the cubic foot and half cubic foot sizes come in different bags to the 1.5 cubic foot bags.  These smaller sizes are unmarked with basic labels.  This helps us keep our costs down for you.  The 1/2 cubic ft bags are the only size available with free shipping.

Due to high shipping costs to some parts of the US (due to the weight of the soil), we also offer our Nutrient Pack for those who prefer to make their own organic living soil using locally sourced inputs.

Pick up is available at a selection of local WA locations. These orders will need to be fulfilled with us directly.  Please call 425.558.0990 or email with any inquiries, to process your payment and book an in-person appointment.

First time customer

High quality soil. The mix smelled, looked and felt great, plus the plants are happy right out of the bag. Based on the quality of this product, I would feel comfortable buying this again or any other KIS product.

Thank you Benjiplant!

I love it. Benjiplant gets all the credit. He uses your products in his YouTube videos… I mix orchid bark and perlite in the mix cause I tend to overwater. Don’t have to fertilize for 6 months. Let nature do it’s thing!

Fastest I've ever had seedling grow!

So far it has been stunning! The seedlings I have are growing faster and thicker than any soil I have previously used! Excited to see how it continues!

Great Company

Have had a few great experiences. The only problem I had with my last order was a busted bag in the box. No big deal I was still able to use the Best soil company out there.
