Orchids? Anybody?

[CapricornFarm]

Define "substrate." Mine are in a chopped woody substance in plastic cups. When I remove them from the wood chips there is a small, damp root ball about the size of a golf ball. Which of these is "substrate?"

Substrate is what they're planted in. Always use one made for orchids. If it holds too much water, the roots can rot.

Thank you! What do you think about sphagnum moss?
