This coupled with our 100% organic nutrients and beneficial bacteria, you won't have to worry about feeding your plants during your entire growth.

How To Use

As the name suggests, OLDGROWTH water only soil contains all the nutrients required to grow and finish your plants within a 9-10 week cycle. This eliminates the need for expensive nutrient regimes. As all the nutrition your plants will require is already built into the soil, all you need to focus on is maintaining a strong population of beneficial bacteria.
To successfully replenish and nurture these bacteria simply inoculate your soil on alternating weeks with our Root Roids and Fruit Roids. By doing so you deliver millions of beneficial bacteria & fungi to your soil. This will help your plants withstand adverse conditions & stress from drought, and also suppress any pathogens that might be introduced to your growing area.
We suggest maintaining an even moisture within your growing containers for best results (moist, not wet). Constant wet and dry fluctuations can have adverse effects on your root's ability to uptake nutrients as it requires. The easiest approach for gardeners is to water your soil with a low-pressure stream provided by a "pump sprayer pack". These units are inexpensive and easy to clean. Most importantly they deliver your water evenly across the surface of the soil as you move the jet back and forth.
Alternatively, for larger gardens, automatic gravity-fed systems such as the well-known Blumats, work extremely well. Other styles of growing such as Self Irrigated Planters and Earth Boxes, also have tremendous results with our Water Only Soil.
