This is a specific conversation about Reptile setup — getting the environment right — ask about yours and get one honest answer for your exact situation.

A misting timer failure with a green iguana is a serious problem — these animals need 70–80% humidity consistently, and even a few days of dry conditions can cause dysecdysis, respiratory issues, and serious dehydration. Reptile welfare is almost entirely determined by getting the environment right: temperature gradient, UV lighting, humidity, and substrate all need to match what they'd experience in a Central American rainforest canopy. Getting it wrong — even accidentally — causes chronic stress and illness fast. So I can help you find something more reliable: how old is your iguana, and what misting setup were you using when it failed?
She's about three years old, so pretty large now — maybe four feet. I had one of those cheap plug-in timer socket things running a basic pump mister. The timer just stopped triggering and I didn't notice for about four days. She's okay but her skin looked really dull and she was sluggish. I need something that won't just silently fail on me again.

Four days without misting for a three-year-old iguana that size is genuinely stressful — dull skin and lethargy are exactly what you'd expect. The core issue is that a generic plug timer has no feedback mechanism. It fails silently and you have no idea. What you need is a purpose-built reptile misting system with its own dedicated controller, not a workaround using household timer hardware. What does her current enclosure look like in terms of size, and are you misting into the air or onto surfaces as well?
It's a large custom wooden vivarium, about 6 feet tall and 4 feet wide. I was just misting into the air with a single nozzle. Probably not ideal but it seemed to work when the timer was actually running.

For an enclosure that size with an iguana that big, a single nozzle into open air is going to struggle — a lot of the moisture disperses before it can raise ambient humidity effectively, especially in a wooden build which can actually absorb some of it. You want multiple nozzles positioned to hit foliage and surfaces, which then slowly release humidity as they evaporate. That's a much more stable and efficient approach. The system I'd point you toward is the MistKing Starter System — it's a proper reptile misting unit with a programmable timer built into the pump controller itself, not a separate socket timer. It's reliable, the tubing runs to wherever you place nozzles, and you can add a second nozzle easily for a build your size. It's used by serious keepers and zoological collections alike. Much harder to have a silent failure because the pump mechanism itself is the timer — if the pump stops, you hear it, and the system is robust enough that random failures are rare. Would you want to add a digital hygrometer with an alarm threshold as a backup safety net on top of that?
Yes, that makes a lot of sense. And honestly yes — I'd love something that alerts me if humidity drops below a safe level so this doesn't happen again even if something does go wrong.

Good instinct. Pair the MistKing with a ThermoPro TP65 — it's a wireless thermometer and hygrometer that has a min/max alarm function, so you can set it to alert you if humidity drops below 65% for example. It's inexpensive, accurate, and gives you a real-time readout you can check at a glance. Between a dedicated misting controller and an independent humidity alarm, you've got both redundancy and visibility — which is exactly the setup a four-foot green iguana deserves. She should be back to normal skin and behaviour within a couple of sheds once humidity is stable again.
That's really helpful. I'll order both. Should I do anything extra while I wait for them to arrive given she's been through a dry spell?
inparticular.ai
Yes — hand mist two or three times a day with a decent spray bottle in the meantime, focusing on the leaves and climbing surfaces rather than directly at her. Give her a lukewarm shallow soak for 20–30 minutes every other day if she'll tolerate it — iguanas absorb water through their skin and will often drink during a soak too. Make sure her basking spot and cool side temps are still correct (95–100°F basking, ambient 80–85°F, cool side around 75°F) as dehydration and temperature stress compound each other. She should perk up quickly with humidity restored.
