The pic shows two backbulbs from Cycnodes Taiwan Gold "Orchis" separated from the plant during repotting on 10th March 2010, put in a pot with soaked Perlite, stood in (one of ) my ordinary aquaculture trays with water/nutrient mix about 1 inch deep. The pot is about 4 or 4 1/2 inch size. When the new bulbs reached this size a couple of weeks ago, I took the pot out of the water and placed it in this hanger pot so as to hang it up and let the bulbs mature and the compost dry out. I shall watch it, and when the new growths start which - from experience maybe tomorrow, next week or next month - unlikely to be as late as next year !
I shall probably separate into two new plants , remove the original now yellowed bulb, and let them grow away to flowering size which I expect to be on the next growths.
The original plant has bulbs now about 7 inches high , maybe 2 inches thick, and the flower buds are bumps on the bulbs ready to break through any time now - the parent has the same treatment of growing in this hydroponics system, and being taken out to dry off a bit when the bulbs are complete, and stay out until the flowering is over - probably it will be in flower for 3-6 weeks over Xmas and the New Year.
