The first results with the semi-hydroponic Small phalaenopsis seem encouraging and that now the majority of transplants have recently been made in this way.
The substrate consists of expanded clay. On the sites we recommend a selection of the size of grains of expanded clay but I have considered a finesse a bit 'extreme. As containers I used a bit 'ordinary jars, plastic plants, a few glasses of various plastic and container. In the plastic cups I practiced three or four circular holes about an inch from the bottom. I've then filled with expanded clay thoroughly washed and above I have laid the seedlings of phalaenopsis sfiascate just covering the roots with some other clay expanded to give a minimum of stability. Under normal ones placed in jars I put a small saucer in which a thin layer of water allowed to accumulate.
The advantages of this type of operation are given by the fact that the expanded clay, being a neutral material, will not rot, and prevents the proliferation of pests that can still be easily washed away. Both normal in jars that have the saucer, both in plastic cups with holes half an inch from the bottom, it accumulates the water by capillary action back to the top always providing a good dose of liquid plant. The expanded clay
counter does not provide any nourishment to the plant so that in almost every watering is good to add a lot of balanced fertilizer diluted. I do a 5-5-5 and a half milliliter for orchids in about one liter of distilled water by adding a little 'tap water to provide a minimum of calcium.
The results were surprising at the time. Plants sfiascate just do not seem to be any shock, such as those placed in sphagnum. Shock which normally stop growing for more a month. In contrast, perhaps because it placed in a ventilated environment and with new food, the plants tend to grow quickly, issuing new roots that stretch very quickly making its way between the balls of expanded clay. The leaves tend to lie with a certain speed and forth new ones.
Soon I will publish the progress of this sfiascamento which were pretty interesting.
