I grow only in an indoor plant room using all LED lighting. It is not a large room so I can not hold more than about 125 mature plants. I decided to focus on Cattleyas, particularly species. I also have a focused Phrag collection because of long term connection to Orchids Limited. A few Paphs are thrown in. I have good control of temperatures so mid-winter I run 56 F at night and 70 day for a few months and mid summer I run 70 F night and 84 day. Spring and Fall temperatures gradually transition. I grow using a parfait of Hydroton and Grodan rockwool cubes. I use Green Jungle, K-Lite, and KelpMax for nutrition.
