Advertisement How frequent should I put droplets of water for my A. Metallica sling? It's still 1" and it seems kinda happy. But I read online that Avicularia slings are very sensitive to ventilation and humidity I currently put around 3 droplets of water in its web every 2 days. I keep it in a small temporary enclosure with cross ventilation and it has a mini ceramic heater that keeps it warm. Would the heater affect how I should control the humidity? My hygrometer/thermometer is still being shipped but I'd estimate it to be kept at around 75-79 degrees Fahrenheit. I have a mechanical timer that turns the heater off every few hours to let the cool in. Should I change this? My heating bulb is coming with the hygrometer. Would it be better to just use the lamp and get rid of the ceramic heater? I'm planning on keeping the heater for my slings and having the lamp for the juveniles-adult Ts should I go through with it?
