Frequently Asked Questions

Does HGO work with worm castings?
Yes
How long will it take to notice any changes?
As little as 10-14 days
Does HGO still work if I reuse my soil?
Yes, in fact we recommend this method
Can it be used with CoCo?
Yes
Can you top-dress with HGO?
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.
How much do I use with 1 gallon of soil?
1.5 cups
How many times should I apply HGO during a single season?
1 application, mixed into the soil.
How does HGO help with pest control?
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.
How do I apply HGO to potted plants?
Mix thoroughly with your desired potting soil at the recommended application rate on the package.
What is the best way to apply HGO to raised beds?
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.
Do I need to change my watering regimen after I apply HGO?
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.
Do I need to change my fertilizer regimen after I apply HGO?
HGO will supply the plants with some micronutrients. Depending upon what you are growing and the base material you are using, fertilization may change.
How much will HGO affect the pH levels of my soil?
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.
How are the minerals in HGO made available to the plants?
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.
When is the best time to add HGO to my soil?
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.
Does HGO work better indoors, or outdoors?
Works great with both!
Can I use HGO with hydroponics?
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).
Can I use HGO during composting?
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.
What is the shelf-life of HGO?
HGO doesn’t expire!
Which types of plants benefit most from HGO?
Anything that fruits, flowers, or produces vegetables.
Are there any synthetics chemicals or substances in HGO?
No
Are there any pesticides in HGO?
No
If HGO comes from old mining operations, how can I be sure that nothing harmful is still in the mixture?
All of the chemicals used in leeching are neutralized naturally over time, or through our processing plant.
Can I eat fruits and vegetables grown with HGO?
Yes
Are there any health hazards I need to consider when working with HGO?
Take care not to inhale
How does HGO contribute to sustainable gardening/ farming practices?
It does not dissolve or dissipate, so if you reuse your soil, you reuse HGO. HGO is also a recycled material.
What happens if I use too much HGO?
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.
Are there any plants that I can’t use HGO with?
No
Is HGO compliant to use for organic gardening/ farming?
Yes, per NOP standards
