Reptile Terrariums Misting Accessories kit, Reptile Mister Nozzles, with 10 Misting Nozzle, 5 Brass Plugs, 3 Plugs, 1 Misting System Filter, 16ft 1/4 inch Tube, Black

If you don't mind spending about $50 I have used this in my paludarium and will be putting a couple in my greenhouse when I stop being lazy. It lets you set misting frequency and duration. Just run the inlet tube into whatever container of water you want. You can also just unscrew the misting tips if you want to increase flow and stop misting. It uses the same size tube as aquarium air hose so you can get a small roll of it if you want a long run. You can also buy more misting heads from them or from other listings on amazon. I highly recommend getting extra brass tips if you plan to use the misting function long term with anything but distilled water since the mineral buildup will clog them. I tried using vinegar and a toothpick to unclog mine but it didn't really work.
