L10062  GD-Thomale original Medium, complete

Complete medium for sowing species and hybrids of Paphiopedilum.
GD-Thomale full-strength is a good medium for many easy germinating
Paphiopedilums. Modern modifications of GD-Thomale are the RE medium
(R. Ernst, 1992) and the BM medium (J.M. van Waes, 1984). This product
is the original medium as described by the late Hans Thomale, a German
orchidist and professional nursery man, and performs well with the easier to
germinate species and hybrids of Paphiopedilum. Note: The content of
iron salt without chelating agent is sufficient for germination purposes,
but for replating to add chelating agent or additional chelated iron is
recommended.
