I bought this bulb from JEM 2 years before they closed. Friends with me laughed because it took 2 hours to decide which plant to buy. It started out with two leads. Mounted on a 8 X8 inch piece of tree fern. Grew this a little too shady previously but grew any way, didn't bloom though. This spring I moved it sit near the greenhouse roof, right above the thin leaf oncidiums. It grew up one side of the slab, I turned the slab around and it's now grown up the other side. I water daily if the weather permits (i.e., no rain). I water with RO water, but when I fertilize I mix half tap water with half RO for buffering. i would say its grown warm.
