L10054  Murashige & Skoog Orchid-medium 2b (MSO 2b)

Instant medium with complex additives and activated charcoal.
Complete with sugar and gelling agent! Does not contain plant growth regulators.
Still one of the best media for final replating of Paphiopedilum seedlings. Only
some species and hybrids that can stand media with high salts, especially 
high nitrogen, can be replated dircetly as protocorms on MSO 2b, most other
paphiopedilums will cease growth for a long time or will die alltogether and need
to be replated on a special stage II Paphiopedilum medium for early development.
We recommend HPM 1a (Prod. #L10195), it promotes development of protocorms
to healthy young seedlings, which subsequently can be replated on MSO 2b.
