Floris and Hilda Haasbroek

Floris and Hilda have a very nice growing area located between the side of their house and a brick garden wall.  Floris has enclosed this area by suspending a plastic covering over the whole area.  This is essentially a shade structure type of setting with no heat in the winter but the top does keep off any damaging rain. One end is also enclosed with a brick garden wall.  The last end is just shadecloth with a cooling fan /mister combination to help cool things during the summer.  He has incorporated a number of clever tricks into his growing setup to help overcome the cultural conditions favored by Disas.
The first trick is that he uses nozzles that put out a flat circular spray of water only inches above the top of the pots. He does this because he top waters and has to be careful so that the pollinia don't get wet and easily rot which is not only unsightly but interferes with hybridization attempts.  When the plants spike, the flowers effectively rise above the level of water and thus are not wet during the watering.
They grow in a silica sand / fern fiber mix and Floris has developed one of the most complex methods I have ever seen for dispensing water that is slightly acidified by nitric acid.  A picture of that setup is shown below.
Cooling is an ever present problem for those who choose to grow Disas away from their foggy, rainy mountain tops.  Floris also has a clever method of cooling the plants.  They sit on a table of porous concrete blocks.  The blocks have a hole through the center so that there is airflow through this concrete table, which is kept wet.  This provides cooling at the base of the pots and also helps raise the overall humidity on hot summer days.
