I had reported in another thread that when I transferred some of my plants to S/H, only one was not actively growing at the time - my den farmeri.
This was a plant I received from someone several years ago who was not an orchid grower and it was in very bad shape. All of its canes were completely shriveled and it had maybe one viable root. It has not grown at all in the past three years and was destined for the trash bin to save space for heathier plants until I decided to give it one more chance. It was transferred to S/H in the middle of April. This morning, I gave it a good inspection. Not only is it growing new roots, it also has two new growths just starting!
I'll try to take pictures later. If this plant blooms next winter, I'll forever be a convert.
