Buying Guide
Understanding Airflow vs. Humidity
I have learned that choosing a screen cover is a balancing act. A full screen top provides excellent ventilation, which prevents mold and respiratory bacteria. However, in dry climates, too much airflow can cause your humidity to plummet.
* If you live in a dry area, look for hinged covers so you can partially cover the non-opening side with foil or glass to trap moisture.
* If you live in a humid area, a full mesh top is your best friend to prevent stagnant, “heavy” air.
Structural Integrity for Lighting
As an electronics expert, I always look at how the screen interacts with heat lamps.
* Weight Capacity: Ensure the mesh is “tension-rolled” into the frame so it doesn’t sag under the weight of a 100W ceramic heat emitter.
* Melting Points: Never use plastic-coated mesh with high-wattage heat lamps. Stick to the metal exo terra screen terrarium models to avoid fire hazards.
* UV Penetration: Check the “aperture” (the size of the holes). Finer mesh blocks more UV. The models reviewed here are all optimized for high UV transmission.
Common Questions About Exo Terra Screen Terrarium
How do I secure an Exo Terra Screen Terrarium cover?
I always recommend using specialized screen cover clips. These clips tension the metal frame against the glass lip of the tank. For larger, stronger animals like snakes, using four clips (two on each side) is the only way to ensure 100% security against “push-outs.”
Does the mesh on a screen terrarium block UVB rays?
Yes, all mesh blocks some UV light, usually between 5% and 15% depending on the weave density. In my testing, I’ve found that Exo Terra screens are designed with a wider aperture that allows more beneficial rays to pass through compared to standard window screening.
Can I spray water directly onto the screen?
While you can, I suggest avoiding constant heavy saturation on steel mesh covers, as they can eventually develop surface oxidation. If you are using an automatic misting system, aluminum frames like the ReptiBreeze are a more durable choice for long-term moisture exposure.
Why is a hinged cover better than a standard one?
In my experience, moving a hot lamp every time you need to mist the tank or add food is a recipe for a burn or a broken bulb. A hinged cover allows you to leave your lighting fixtures undisturbed on one half of the tank while you access the other half safely.
How often should I clean the screen top?
Dust and mineral deposits from misting can clog the mesh over time, reducing both airflow and light penetration. I recommend wiping the screen down with a dry brush once a week and doing a deep clean with a damp cloth every month to keep the environment healthy.
