Finally got signed in. I've been growing orchids for close to 40 years, mostly species, and under lights. I especially like miniatures, and of those, I seem to be drawn to those with tiny flowers. I'm currently working on a Arduino-based control system for my cool growing space - it will control light cycle, ventilation, humidification and cooling, with a Raspberry Pi-based web interface. I live in the Philadelphia (US) area.
