This is my first attempt to grow rupicolous Laelia. But this one grows quickly and flowered! I got if from Olympic Orchids as a relatively small seedling with 2-3 bulbs, but it has 7 or so bulbs now within a year. Are other rupicolous Laelia species more difficult than this species? I'm thinking of getting more rupicolous Laelia species.
I don't think I'm using the typical rupicolous Laelia potting mix, but it seems to work. Repotting, which I have to do soon, could cause problems (I've heard that they don't like to get disturbed).
Growing condition: 2.25" deep pot, sphagnum moss, 3" between the top of the leaves and T5 HO, in a grow tent (so 100% artificial lighting), RH 65% day, 80-90% night, Temp: 60F night, 86F day, fertilize at every watering with 50-60ppm N (rotate Jerry's Grow, Grow More Urea Free, MSU) + KLN 2-5 drops/gallon, KelpMax 2tsp/gal every 2 weeks.
