| Original mix as described by Thomale 1954 and 1957 . The GD-Thomale medium |
| has stand the test of time and is the base for several modern media for slipper |
| orchids and difficult to germinate hardy terrestrial orchids. This mix does not |
| contain NAA, an ingredient recommended as 'Wuchsstoff 66-f' by Thomale! |
|
| Salt mix sealed in a heavy-duty plastic bag. The salt mix is very hygroscopic and |
| needs to be used up right after opening the bag. However, if sealed airtight immediately |
| after use it can be stored for some time. Every reopening will increase water content |
| of the salt mix. |
