Controller: Zoo Med Environmental Control Center
Controls heaters, coolers, humidifiers, and lights!
Show/Hide Controller Detail 
NEHERP Staff Description:
The reviews for the newest version of this controller are just awesome, and represent a huge step forward by Zoo Med. This single unit is a standard thermostat, dimming thermostat, hygrostat, and day/night light timer combined. It can be set up to heat or cool as well as humidify or dehumidify depending on your goals. There are three probes (cool side, hot side, humidity), and an awesome nighttime mode which can be programmed to drop temperatures automatically. The wired LCD Remote Controller has a 6-foot lead with a cradle, and can be attached where it's convenient. Like Zoo Med's standard Thermostat, their Environmental Control Center will remember all it's settings in the event of a power failure and has a programmable temperature alarm for safety. There's a whole lot to this thing, and we'd recommend watching their instructional YouTube videoext. link when it comes time to set it up.
Long-time customers of NEHERP know we generally don't recommend automating misting systems with anything but a timer. At our shop we'd be more likely to connect a misting system to Outlet #4 ("timed accessory"), rather than outlet #2's hygrostat. If you plan to use this Environmental Controller's humidification function, our recommendation would be to tie it to a Zoo Med Reptifogger. Simply set the humidity to whatever level you are looking for, and adjust the Reptifogger to a low setting on it's dial. That should end up producing a gentle humidifying effect which can be used independently, or as a backup to a timed Misting System.

Thermostat: Zoo Med Reptitemp
A digital thermostat for heating or cooling terrariums & incubators
NEHERP Staff Description:
Zoo Med's Reptitemp is our favorite On/Off thermostat, and is surprisingly accurate for the price. Reviews elsewhere and our own independent tests have shown that this little unit is probably the best inexpensive mainstream thermostat on the market right now. Unlike most digital controllers, this one can switch from cooling to heating mode seasonally, or for specific applications which require either method of control. In our test unit, we saw a +/-1F swing using this model of thermostat, which is solid for anything in this price range. Like all thermostats, it's critical to use a separate thermometer to meter temperature independently. Doing so will allow the user to have the most accurate and consistent results over time. This has a built-in alarm function, will remember it's settings after a power failure, and is incredibly quick & easy to set up.

Standard On/Off Thermostats
(How the Zoo Med Reptitherm Thermostat works!)
This is how most thermostats work, with the digital variants usually being more accurate than their mechanical counterparts. Mechanical "wafer style" thermostats are notoriously inaccurate by comparison! Standard on/off thermostats work very simply by sending power or disabling power depending on a set temperature and a measured temperature. This is an extremely well proven, functional, and simple solution which works for the vast majority of applications. Please note the graphic is accelerated & exaggerated for the sake of visual animation.
Pulse Proportional Thermostats
(Not how the Zoo Med Reptitherm Thermostat works!)
Pulse Proportional Thermostats gradually raise & lower ("pulse") the power going to the heating element to maintain a steady temperature. This is thought to help minimize temperature swing, but can only be used on certain electronic devices which are compatible with dimmers and/or pulse-capable thermostats. Pulse proportional thermostats are considered a little more precise than on/off thermostats, due to the gradual pulsing of power to the heating element(s). Please note the graphic is accelerated & exaggerated for the sake of visual animation.

Thermostat: Exo Terra Pulse Proportional 300W
A pulse proportional thermostat for heating terrariums & incubators
NEHERP Staff Description:
A pulse proportional thermostat for less than a hundred bucks would have been unheard of just a few years ago. Exo Terra has been stepping up their game with their new line of thermostats, which each include a 5-year manufacturer guarantee. This is an ideal heat controller for many different applications. Like all thermostats, it's critical to use a separate thermometer to meter temperature independently. Doing so will allow the user to have the most accurate and consistent results over time. This will remember it's settings after a power failure, and is incredibly quick & easy to set up. Not sure about the difference between On/Off and Pulse Proportional thermostats? Learn More!

Timer: Analog Outlet Timer
An economical grounded 1725W (15A) timer
NEHERP Staff Description:
This inexpensive timer is simple, reliable, and long-lasting. We had some of these running our grow lights at NEHERP for years before moving locations and upgrading to our digital model. Using a timer to automate the day/night cycle for a live vivarium helps promote a healthy circadian rhythm, which benefits both plants and animals. Includes a manual "on" switch to bypass the timer for convenience. Minimum 15 minute on/off intervals. Rated for 15A/1725W.

Timer: Dual Outlet Digital Seconds Timer
Our most precise timer with digital seconds control!
NEHERP Staff Description:
These digital timers offer 8 user-selected on/off cycles per day, with each day's schedule individually programmable down to the second. We recommend them controlling misting systems, foggers, day/night lighting, lighting effects (storm, overcast, lightning-emulating LEDs, hydroponics, and more. Two grounded outlets offer easier connection of multiple devices. (Note: Each outlet not separately programmable.) Unlike analog timers, this digital unit won't require adjustment after a power outage. Minimum 1 second on/off intervals. Rated for 15A/1725W. UL Listed for safety.

Timer - Dual Outlet Digital Minute Timer
A budget-focused timer featuring minute (not second) control
NEHERP Staff Recommendation:
If you don't need down-to-the-second control, and aren't worried as much about brand names, and aren't concerned about resetting a timer after a power outage, a generic digital outlet timer could save you a few bucks. These digital timers offer 8 user-selected on/off cycles per day, with each day's schedule individually programmable with minimum of 1-minute intervals. We discovered this brand in particular when searching for remote outlet timers, and ended up using a few of their minute timers at our shop when our primary distributor was sold out during the pandemic. To put it simply, these timers work great for basic lighting controllers. 
We don't carry these at NEHERP, so please check them out at the above link.

Timer: Digital Terrarium Controller
A reliable digital power strip
NEHERP Staff Description:
We've found these digital power centers to be very useful when working with live vivariums. There are 8 grounded outlets in total. Two outlets are dedicated to daytime, two are dedicated to nighttime, and four outlets remain constantly powered. The constantly powered ones are perfect for thermostats, misting systems, foggers, or water feature pumps. There are up to 7 daily time cycles, but we've only ever needed the basic 12-hour cycle for live vivarium use. For reliability & peace of mind, we stock & ship authentic US brands (Zilla/Coralife) only. Each outlet has a sliding cap for safety, and this unit comes with a grounded 3ft cord.

Timer: Zoo Med Terrarium Controller
24-Hour programmable analog timer
NEHERP Staff Description:
The Zoo Med terrarium controller is handy for all sorts of different setups which require both continuous and timed outlets. Just about every species benefits from a scheduled day/night lighting cycle controlled by a reliable timer. (Usually 12 or so hours on/off) Then there are the other accessories like thermostats, heaters, fans, and misting systems which require power 24/7 in order to function properly. This nifty controller has 4 outlets which are always on plus 4 outlets which are controlled by the built-in timer. With this setup, you could keep all of your accessories plugged into the "always on" outlets and use the timed outlets for your enclosure's day light. This is now our only "terrarium controller" model, after dropping a competing digital product which couldn't match the good reputation of the Zoo Med model. Includes "all on" switch to bypass the timer for convenience. Each outlet is grounded, and the controller is rated for a total of 1000W.
Manufacturer Description:

NEHERP Tip: Keeping Conditions Stable
Using Glass Inserts & Tops
NEHERP Product Recommendation:
Working to keep conditions stable in a terrarium can be tough with a full screen top. Every single one of our live vivariums uses Glass Inserts to control airflow and keep conditions stable within the enclosure. Our Glass Inserts and Glass Tops are cut by hand right here in Connecticut using real glass. Expect a perfect fit on your terrarium with excellent light transmission. Since they are real glass (not cheap plexi/acrylic/plastic), they won't bend/warp over time!

Sorry, our inserts aren't a perfect fit with other brands!
