About Heating
Most of the vivariums our customers build require a minimum of 55% relative humidity to thrive. Many methods of heating enclosures will drastically reduce humidity levels, so it's important to balance air flow when possible. Sealing part of the enclosure's top using glass inserts (or similar) will act as a basic insulator & help keep both heat & humidity within the enclosure. Once airflow is controlled properly, both temperature & humidity should remain more consistent & easier to control.
If you'll be using a basking area, we strongly recommend utilizing a thermostat with a probe mounted near the hottest area. There are many available heating solutions, but we don't recommend using any without a thermostat for safety. Our favorite setup for a basking area would be with a Pulse Proportional Thermostat, Wire Fixture, and Ceramic Heat Emitter. The simplest setup would be with a Basic Thermostat, Basic Dome Fixture, and a Black Incandescent Light. (This paragraph assumes you'll be using a NEHERP Vivarium Lighting Kit, so you won't need additional visual light from a "day" basking spotlight!)
To slightly raise the temperature within an enclosure, we recommend using a Zoo Med Under Tank Heater mounted to the side or rear of an enclosure. Zoo Med Repti Heat Cables can alternatively be used in either of those locations. We try to mount these types of heaters as low as possible, and out of sight. A thermostat is a good idea for this type of thing, and either heating method is compatible with any thermostat we carry.
2) Our vivarium lighting kits can be placed over our glass inserts without issue, but it's important to never position UVB or heat lamps over glass inserts.
3) Under tank heaters are technically not supposed to be used underneath a properly built live vivarium, due to the water in the drainage layer.
4) If the ambient room temperature will ever get cold enough to be potentially dangerous for your pet, please read this important info.

Ceramic Heat Emitters
High quality & long lasting heating solutions

Ceramic heat emitters produce intense infrared heat while producing no visible light. These are suitable as a 24-hour heat source for a wide variety of situations ranging from tropical to desert environments. Since they don't produce any light, Ceramic Heat Emitters won't negatively affect any animal's circadian rhythm. (Day/night cycle) These are compatible with rheostats (dimmers), standard (on/off) thermostats, or pulse proportional thermostats. In our experience, ceramic heat emitters last considerably longer than incandescent bulbs.
We strongly recommend using a heat controlling device (thermostat or rheostat) and a probe thermometer with all Ceramic Heat Emitters. (Especially 60-150W models!) If you are using a partial glass top or our Glass Inserts, be sure to position the heat emitter over the screen portion to prevent thermal stress cracks on the glass. Also ensure your fixture's rated wattage meets-or-exceeds the wattage of these very hot ceramic heat emitters. We recommend Zoo Med Nano Domes for the 25-40W models, and either Wire or Mini Deep Dome fixtures for the 60-150W models. Brands vary by model, and we only carry major US brands w/12-month replacement warranties serviceable directly through us for your convenience!

Glass Tops For Aquarium-Based Terrariums
The industry-standard glass lid for any standard aquarium!

Keeping humidity in an enclosure is critical to a live vivarium's long-term success, and these glass tops can be used to help achieve that goal. These tops are made from two pieces of hinged glass, plus one piece of flexible clear plastic. Depending on your application, different combinations of glass/plastic panels can be used to achieve the ideal amount of airflow. (Rarely are all three panels used at once!) Although these were originally designed for aquariums, live vivarium environment enthusiasts use these glass lids in a non-traditional way which combines a screen top with the glass top. Read more...Read less...
Aquarium Glass Top Modification - Quick & easy method:
The simplest & least expensive way to use a Glass Top on a live vivarium is by pairing it with a standard metal screen terrarium lid. Once you've selected which panel(s) you'll be using to help hold in humidity/heat (usually only 1-2 of the 3), set the top into the aquarium rim, and place a Fluker's Screen Top over it. The glass lid will fit into the inset lip of the aquarium and the screen top fits on the outside rim, so they can both fit without contacting each other. This method blocks some light, so be sure to select an appropriate Vivarium Lighting Kit! Also, if your animal species is smaller than the gap between the screen and glass top, it may be worth adding a single line of adhesive insulation strip from a hardware store between the two parts to ensure the animal won't get stuck between the two. This method is not recommended if you are caring for an animal which relies on a diet of small insects (fruit flies, tiny crickets, etc), since the Fluker's screen tops aren't considered "fruit fly proof".
Aquarium Glass Top Modification - How we'd do it:
Up for a challenge? The top style we recommend & use in-house allows for plenty of light, prevents feeder insect escape, and only takes a couple hours of extra labor. This method removes one or more of the plastic or glass panels from the Glass Top and replaces it with a custom made screen frame. Screen frame kits are available from most hardware stores, and the process is pretty straightforward if you've got a hacksaw (or better). Simply install the area of the glass top you plan to use, measure the remaining open space, and build your Screen Frame Kit (using the kit's instructions) to fit. Once fitted, you can install our screen separator as the actual screen material using Screen Spline & a Spline Tool from the hardware store. Remaining gaps around the screen frame can then be filled with beads of aquarium safe silicone, and all excess silicone can be wiped off using latex gloves. (Residual silicone residue can always be scraped off with a razor later!) Once cured, you'll be able to open the enclosure on the glass side, while the screen remains in place. This project is considered "difficult", and shouldn't be attempted unless you are comfortable with a pretty hands-on DIY project involving cutting aluminum framing, sanding down aluminum edges, fitting/mounting screen, and working with silicone to create custom seals.
• Many Aquarium + Top solutions cost the same or more than a better-performing front-opening terrarium, so compare costs!
• Our Vivarium Lighting Kits are OK to place over glass, but never place heat or UVB lamps over a glass section of a top.
