I presently grow my Phals. and mini Cattleyas under a bunch of 54 watt t-5 lights. They have been doing quite nicely so far. Never being satisfied unless I can tweak stuff further, I recently purchased an LED grow light fixture from a Canadian company called MarsHydro. It is the TSL 2000W model. I have not yet set it up so stay tuned. See the specs at:
