After many years of waiting... My Phal. gigantea has two spikes growing. I am very surprised how fast they are elongating, in this rather dark time of the year.
I am not sure how old the plant is, but the leaf span is 28 inches. I grow it in a very large west window with under pot heating. Keeps the plant above 25C at minimum during the day at this time of year.
I have it in a clear vented pot with hydroton, but do not let it sit in water. As they hate to have their roots disturbed inert media will decrease the number of times I need to repot. It sits in a heavy ceramic cache pot with enough room to allow for circulation within.

Now let's see if it will bloom...
