Limestone (Calcitic and Dolomitic)
Used to balance pH levels.
Limestone (Calcitic and Dolomitic) Key Properties
- Correcting overly acidic substrate with limestone can improve the availability of essential nutrients to plants. In acidic substrates, elements like calcium (Ca), magnesium (Mg), and phosphorus (P) may become less accessible to plants. By raising the pH, limestone helps release these nutrients and makes them more available for plant uptake
- Many beneficial substrate microorganisms, such as bacteria and fungi, thrive in substrates with near-neutral pH levels. By adjusting substrate pH with limestone, you create a more hospitable environment for these microorganisms, which can enhance nutrient cycling and overall substrate health.
An inorganic, non-toxic, and lightweight material.
Perlite Key Properties

Pinus Radiata Bark
More absorbent and stronger than fir bark, Pinus radiata is better at soaking up and retaining water and breaks down more slowly vs. fir and other bark products
Pinus Radiata Bark Key Properties
- Processed through maturation rather than composting, making the particles resilient, clean, and free from contamination with soil or other organic materials
- Aging process allows beneficial microorganisms to proliferate while pathogens are eliminated. The outer surface of the bark chip is broken down, allowing it to hold water and nutrients for the plant, while the inner structure remains hard and stable
- Provides a pH level of 5.5 - 6.5 and never requires flushing as the bark does not accumulate salts
- Air-filled porosity 47-54%, water-holding capacity 55-57%, water retention efficiency 25%.
Pumice and Hyuga Pumice
Pumice and Hyuga Pumice Key Properties
Pumice is a type of volcanic rock that forms when molten lava is rapidly cooled and depressurized, causing it to trap gas bubbles within its structure. This unique formation process gives pumice its distinctive lightweight and porous properties, making it a valuable material for
- Pumice is highly porous and has a network of interconnected air pockets, which allows excess water to drain quickly from the substrate. This property is crucial for preventing waterlogged roots and root rot, which can be detrimental to potted plants (Hyuga Pumice is softer and more porous than regular pumice)
- The porous structure of pumice also provides aeration to the root zone. This ensures that the roots have access to oxygen, which is vital for their health and proper growth. Well-aerated substrate promotes strong and healthy root development
- Pumice particles do not compact easily, which helps maintain substrate structure over time. In contrast, compacted substrate can hinder root growth and water infiltration
- While pumice promotes good drainage, it also retains some moisture due to its porosity. This means that it can help maintain a consistent level of moisture in the substrate without allowing it to become overly dry
- Pumice typically has a neutral pH, which means it won't significantly affect the pH of the substrate. This neutrality is beneficial for a wide range of plant species, as they can thrive in substrate with a pH close to neutral
- Pumice is a durable material that doesn't break down quickly, providing a stable growing medium for your potted plants over an extended period
- Pumice is lightweight, which can be advantageous for larger potted plants. It reduces the overall weight of the pot, making it easier to move and handle.
