Frequently Asked Questions

As little as 10-14 days

Yes, in fact we recommend this method

Yes, but with some conditions. Top-dressing with HGO is recommended with looser, potting soils. Be especially conscious to water HGO down into the topsoil if applied outdoors. HGO works best if you can incorporate it into the substrate for a homogenous application.

1.5 cups

1 application, mixed into the soil.

The silica in HGO reduces fungal activity. Silica is incorporated into the xylem and phloem of the plant, thus strengthening the ‘main plumbing’ of the plant. In return the plant can tolerate more environmental stress. It is environment stress that can weaken a plant making the plant more susceptible to pest damage.

Mix thoroughly with your desired potting soil at the recommended application rate on the package.

Applying a 2-4 inch layer to the bottom of a newly
constructed raised bed will create a great barrier between your bed’s soil and the exterior environment, as well as the drainage zone. For your actual soil mixture, use the proportions recommended on the package and mix thoroughly throughout.

You will need to be conscious, especially with potted plants, of over-watering, since HGO retains water for your plants. Be sure to check your soil for moistness before each watering session to get a feel for your new watering schedule.

HGO will supply the plants with some micronutrients. Depending upon what you are growing and the base material you are using, fertilization may change.

Even though HGO has a pH level of 8.4, it will not cause many major swing in overall pH. In terms of CCE (calcium carbonate equivalent), HGO has a low Effectiveness factor and %CCE. Therefore HGO should not significantly raise the soil pH.

HGO comes to you in a state of mineral decomposition, meaning that the Silica and it’s accompanying nutrients are bio-available to your plant as soon as you apply it.

HGO works best at the beginning. Mix it into the soil you plan to start with, but it still work when added to various stages of gardening/ farming.

Works great with both!

It depends on the hydroponics system. Some systems are water only where others use potting soil that is heavy in perlite. (I would need to test the water solubility of the nutrients for hydroponics).

Yes! Add 1/10 HGO to your 9/10 compost mixture during the composting process. The minerals and silica will contribute greatly to the health and balance of the resulting soil.

HGO doesn’t expire!

Anything that fruits, flowers, or produces vegetables.

All of the chemicals used in leeching are neutralized naturally over time, or through our processing plant.

Take care not to inhale

It does not dissolve or dissipate, so if you reuse your soil, you reuse HGO. HGO is also a recycled material.

Too much HGO can reduce the CEC of the soil. Low CEC means that the soil cannot hold onto nutrients so you have to fertilizer a little bit all the time. To increase the CEC you can apply organic matter like compost.

Yes, per NOP standards
