We bloomed ours to death, so take this advise as you will: We grew the psychopis right along with the oncidiums. Same water, fert, and light. The spike can get very long. 3'+ We finally tied it up so that we would not break it off when watering. The cool thing about a psychopis is that the spike is stiff enough to support the bloom and as it moves in circulating air, it looks like a butterfly fluttering around.
