Pebble Tray To Increase Humidity
Pebble tray to increase humidity
This change in humidity above a pebble tray was tested by an orchid enthusiast. He found that in winter (see top meme), the humidity at 1.5″ above a pebble tray was 3% higher than the rest of the room. At 4″ this dropped to 2% and at 1 foot above the tray there was no increase in humidity.
