I need CP experts:
I usually raise orchids and epiphytic cacti and broms. I have one ping (purchased to get rig of pesky fungus gnats). Problem, the ping doesn't seem to making any dew - as evident by several gnats swarming around the plant, landing on it and flying away.
Conditions: W/SW window no shading other than by larger orchids (dends and cattleyas, as well as adenium obessum - for comparrison). Humidity 45-70% and daytime temps 60-70F and night temps 50-60F, depending on outside conditions. I water with RO or rainwater and tap water (rotate) once or twice a week,no fertilizer. It flowered twice, and made another rosette of leaves, they don't seem sticky. Is the dew seasonal?
