Last weekend I left her with a dripper and some crickets/mealworms with veggies at the bottom of her cage so crickets have something to eat. When I came back Monday she seemed perfectly fine and her urate is still white so I do not think there was any dehydration issues. Will this become an issue if I continue simply using a dripper? Ive asked local petstores that leave their chams over the weekends and they simply leave a dripper on as well. Its much easier said than done to invest $150 on a good auto-mister.
However, I used a water fountain pump ($15) and some rubber tubing to create a rain system. I plan on using that this weekend on a timer so she gets water over the weekends. It obviously not as good as a mister but it does provide artificial rain over her terrarium so I do not see any issues with this. Thoughts??
You could build a rain system with a Mistking.
Without seeing the rain system and how well it performs no one could tell you if its enough or not.
However going to have to be the voice of concern here. There is a reason people pay 150 for a mist king, it isn't because a pond pump cant do the job. It is because a pond pump doesn't last, and is far far from reliable.
Mistkings can and do fail, however a 15 dollar pond pump is much much more prone to failure. Then you have to look at temps, if on a semi hot weekend that pond pump fails and you are not there for 2+ days, that could easily become a death sentence.
Let say you leave on friday at 2, and its a warm day, the pump fails before the night mist, then you return on Monday morning. That is 3 days without water, that could prove fatal at worst, at best will cause some serious dehydration issues.
In a case of a house, where you can watch the pump all the time and make sure it is working is one thing. When you are gone for weekends its a major issue, you need that reliability and that comes with a price.
Let me be clear I am not saying you cant build a pond pump system that will work well and be reliable. I am saying that a reliable good pond pump is going to cost more than a Mist King (or about the same). Reliable high end pumps you can trust cost money it is that simple, if you cant afford a reliable pump then I would suggest you take the cham home on the weekends or go there on the weekends to water.
A failure is just too risky. I see this all the time in my other hobby, which is PC watercooling. There is some great pumps in that hobby, they cost 100+. People all the time go to home depot and buy a pond pump or some Chinese version of our pumps. 2-3 months later, they end up with a 2-3k dollar brick they're computer is trashed because they bought a crap pump(worst case, mostly the PC shuts itself off, and they keep replacing pumps).
In your case, I would go further than 150, because honestly in your case I would buy a mist king and a second mistking pump and run 2 pumps in parallel. You can not afford a failure.
At the very least, if you insit on using your pump setup. I would setup a shelf above the cage and make a dripper that holds a few gallons. That way when the pond pump fails (this isnt an if, this is a when) the dripper will still be dripping. You need to make sure the dripper has enough storage to make it till monday.
Edit: just saw you plan to use a dropper with it. In that case, I think it will be okay. However if temps get really hot one Saturday I would urge you to check the system that day. As temps play a vital role. Providing enough water when the ambient is 70 and when ambient is 90 are totally different.
