I don't think I said before, but I had a disaster in my collection last year , and lost maybe 3/4 of all my plants - or had them so badly damaged that got rid of them anyway. Since then I have been rebuilding, having changed my conditions to suit much cooler growing orchids ; gone are the large Vandas, and most of the cattleyas ; in come cymbidiums, masdevallias, pleiones, disas etc.
I am growing the disas in a stream of water running in a length of gutter. The water is recirculated continuously and flows through a refrigerator ( I had a bit of fun building this ; and modifying it from time to time ). But the point here is that some of these plants grow in the wild on top of Table Mountain, in South Africa, where there is a mist, low cloud, hanging about all day for 3 days out of 4. So the stream is formed of newly condensed mist, and is cold. My 'frig drops the temperature by about 7 degrees C ( 14 degrees F.). Today - England south coast - we had a lovely eartly summer day , 20 C in the shade in my garden, 30 in the greenhouse, but 23 in the stream. 20 or even lower would be better - Mark 4 is being planned in my head to achieve this.
The top one is D.,uniflora - which usually has three flowers despite the name , here seen in the formn 'Red River' where it grows wild. The next is a hybrid - D.Kewensis , and the clone is 'Alice' ; the two with much smaller flowers are species - tripetalloides with white floweers, and aurata with yellow flowers.
I hope to start hybridising next year, when these plants are a bit bigger and stronger -it is too much to expect a young plant in its first year of flowering to bear a seed pod, without the risk of killing it. Fortunately ( since I am already a young 82 year old) they are fairly quick to grow - or so I am told.
