This type of isolation of young plants occurs in orchids by transferring them to new nutrient media, because they grow faster in the closed atmosphere of the glass vessels. The same culture media are used as were used for sowing. Again, complete sterility is the first requirement for success. The way of working is similar to that of sowing. Hold both glasses in your left hand over the steamer, picks up a small amount of the young plants with a long-handled spatula and transfers them, without touching the glass walls, on the new breeding ground. After careful distribution over the entire area, the Protocorme should have that much space, that they can grow to the point of being transferred to the open air. Now – and more later – shows up, that a closer community promotes development more than the advanced level.
This first part of the development then ends, when the young plants crowd and have no room to spread out. A transfer to the open atmosphere should by no means take place too early. Experience teaches again and again, that the seedlings grow so much the better, the stronger they are. A more precise indication, at what age should be transferred, can not, because there are significant differences in development within the genera. The culture medium and the environmental conditions also have an influence ; their effects can produce significant differences, especially when they are installed in the room. One can about 8-12 Expect months after sowing, that the transfer must take place.
