My quick vacation with my family this weekend made me realize how high-maintenance my CPs are right now. I've read about people using miniature pumps on a timer to water their nepenthes in terraria. What kind of pumps are you people using, and where do you get them? I'd like to automate watering of plants with different needs, and therefore need multiple pumps. So i'd like to find the least expensive pumps that will reliably do the job.
I was also thinking it would be nice to run the pumps when the tray runs dry. Does anyone use a float-switch or some kind of moisture-switch to control their watering system?
