Growing and Flowering Hoya graveolens Part One

I was unsuccessful in bringing Hoya graveolens to flower under artificial lighting.  Peduncles would form and eventually dry up and fall off.  Buds would never form.  I believe it requires strong light in order to flower, and this was achieved for me in an outdoor tent greenhouse where most of the plants in the tent got sunburned.  Three peduncles eventually developed buds and flowered under those conditions.
