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.

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!

SUGGESTED APPLICATIONS AND TIPS

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 mbar; for best results use 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.
