CharcoalEdit

  • pH:7
  • Thermal Mass: Medium
  • Water retention: Medium
  • Stability: Medium

Charcoal is a black colored residue containing impure carbon created by burning and extruding raw wood material. Charcoal is known to collect salts and absorbs the acid in excess fertilizer.

Coconut Husk fiberEdit

  • pH:
  • Thermal Mass: Low
  • Water retention: Low
  • Stability: Medium

Fir BarkEdit

  • pH:4.2 - 7.4
  • Thermal Mass: Medium
  • Water retention: Medium
  • Stability: Low

Fir Bark is a relatively cheap medium produced from plants in the genus Abes. It is good for providing air circulation and with holding moisture. The bark degrades slowly and pieces shrink as the bark degrades. Degrading is sped up when a high nitrogenous fertilizer is used. Fir bark comes in three grades fine, medium, and coarse.

Fine bark is around 0.6 cm (¼ inch) wide and usually used for plants with fine and thin roots. It is also used for new and developing plants.

Medium bark is around 1.3 cm (½ inch) wide and is usually used for epiphytes such as Cattleyas

Coarse bark is 2.5 cm wide (1 inch) wide and is used for plants with aerial roots such as Vandas and Phalaenopsis

GravelEdit

  • pH:7
  • Thermal Mass: High
  • Water retention: Medium
  • Stability: High

Lava rockEdit

  • pH:7
  • Thermal Mass: Low
  • Water retention:Med
  • Stability: High

New Zealand Sphagnum mossEdit

  • pH:7
  • Thermal Mass: Low
  • Water retention: High
  • Stability: Low

Peat MossEdit

  • pH: 5
  • Thermal Mass: High
  • Water retention:High
  • Stability: Low

Osmunda fibersEdit

  • pH:
  • Thermal Mass: Low
  • Water retention:Low
  • Stability: Medium

PerliteEdit

Perlite
  • pH: 7
  • Thermal Mass: Medium
  • Water retention:Medium
  • Stability: High

Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. Perlite is relatively light and it is used to make composts more open to air, while still having good water-retention properties. It is commonly used in hydroponics.

Tree fern fibersEdit

  • pH:
  • Thermal Mass: Low
  • Water retention: Low
  • Stability:Low

Tree fern fibers is the material from the bark of plants in the genus Cyatheales They are resistant to decay but retain lesser water.

SandEdit

Beach sand
  • pH:7
  • Thermal Mass: Medium
  • Water retention: Medium
  • Stability: High

Sand particles are 20 to 2000 µm wide


SiltEdit

  • pH:7
  • Thermal Mass: Medium
  • Water retention: Medium
  • Stability: Moderate

Silt particles are 2 to 20 µm wide


ClayEdit

  • pH:7
  • Thermal Mass: Medium
  • Water retention: Medium
  • Stability: High

Clay particles are less than 2 µm wide. Clay particles are an essential element in some soils due to its electro negative charges which attracts and holds cation such as K+, Mg+2, Ca+, and H+ which causes the nutrients to less likely be leached away by water. Clay also plays an essential role in cation exchange system with terrestrial roots.
