What is the difference between the two arboreal towers, AeroVent & LightVent?

The AeroVent and LightVent arboreal towers have distinct bottom sections and ventilation placements to accommodate different species' ventilation and humidity management needs. Both models are compatible with several accessories, allowing for numerous configuration possibilities.

Choosing the proper jumping spider enclosure is crucial for your pet's health and well-being. The AeroVent and LightVent models offer innovative solutions tailored to arboreal species' specific ventilation and humidity requirements, making them an excellent choice for any enthusiast.

Ventilation and Structure:

The AeroVent "Glass-Core" includes additional ventilation lines across the side-bottom glass panels, enhancing cross-ventilation, which is essential when using a substrate tray directly. In contrast, the LightVent features a slim, fully ventilated bottom plate, allowing full-length glass panels on three sides, maximizing visibility and airflow.


These jumping spider enclosures have a very efficient ventilation mechanism, allowing for a nice view through the glass panels. The humid air rises from the bottom, promoting cross-ventilation through the stacking effect driven by the buoyancy of moist air (learn more in detail with our "Enclosure Ventilation, Humidity & Temperature Guide").

Substrate Tray and Ventilation Plate Integration:


The AeroVent habitat includes a substrate tray by default, and the LightVent habitat includes a ventilated bottom plate. Ventilated plates and substrate trays can be purchased separately or as add-ons. 


The substrate tray is a detachable bottom that holds inert or inorganic materials such as coconut fibre, moss, coarse dust-free sand, wet cotton, or paper towels. These materials serve as a humidity buffer but are not suitable for burrowing. The tray facilitates easy material replacement to maintain cleanliness and manage waste.


The ventilation plate enhances airflow and provides a clean, open look. It can be installed at the bottom or on top of the "glass core" to provide even further airflow. 


When the substrate tray is used with the ventilation plate, it acts as a barrier to prevent organic waste from contaminating the wet material beneath. This setup simplifies maintenance by allowing the removal of the magnetic tray without fully opening the jumping spider enclosure, while also creating a moist air buffer under the ventilation plate. This configuration ensures strong airflow and effectively utilizes the evaporating tray's moisture, which is drawn into the glass core through aligned magnets on each stack.

Species Suitability and Environmental Adaptation:

The AeroVent is well-suited for species with high ventilation and humidity needs, making it ideal for environments with dry air. The buoyancy-driven stacking effect helps circulate moist air throughout the habitat as it evaporates from the substrate tray. Placing the substrate at the bottom can create a more natural look. 

On the other hand, the LightVent is optimized for species that require significant airflow in properly acclimated rooms. Species that do not require substrate often benefit from the added ventilation while keeping a relatively clean, spacious, empty bottom. However, the tray and plate can be combined for the best of both worlds.

Selecting the appropriate jumping spider enclosure is key for enthusiasts looking to create the perfect habitat. Our arboreal glass towers provide unmatched flexibility and customization options, ensuring your pet has a comfortable and safe environment.

Differences with the Duo & Tri Glass Habitats:

Simple: The “Duo and Tri glass spider enclosures” are meant to use long-term or more significant substrates and do not have a removable bottom. They are meant for species that need substrate to burrow or catch prey. For example, many arboreal tarantulas require a substrate, even if they have arboreal behaviours.


The Duo & Tri glass product can be customized long, wide, or tall, with different proportions and many more size options than the towers. This is because there are many more terrestrial species with different needs than only arboreals. When made tall or with long proportions, the Duo & Tri glass habitats can also function as a pet jumping spider enclosure.

One key difference is that the arboreal glass towers utilize a bottom-to-top ventilation flow, while the duo and tri glass systems rely on air entering through one or two side walls and exiting through the top lid. The top lid features a ventilated rim and a removable glass section.

The arboreal glass towers have a removable bottom, which allows for more service access and allows for frequent cleaning of the bottom surface.

Ventilation Lines vs Holes

Ventilation, why lines instead of holes or mesh:

Traditionally, cross ventilation in acrylic jumping spider enclosures is achieved through holes or mesh on opposite sides, as drilling holes or installing mesh discs is more straightforward than creating precise thin lines. However, 3D printing technology makes crafting thin, long ventilation lines within intricate plastic parts feasible. Such lines provide excellent airflow and prevent escapes by spiderlings or fruit flies while avoiding the risks of leg or fang entrapment often associated with mesh in tarantula setups.

The big question is: do lines provide more ventilation? Yes, they do.

Let's break down the ventilation metrics for a standard 10x6 cm ventilated wall. The rear panel features ten vertical ventilation lines, each 9 cm long and averaging 0.45 mm in width, although we'll calculate using a maximum width of 0.5 mm for simplicity. Thus, the open area per line is calculated as 90 mm multiplied by 0.5 mm, giving 45 mm² per line. This results in a total of 450 mm² of open area across all ten lines.

For comparison, consider a typical small hole in an acrylic jumping spider enclosure measuring 1 mm in diameter. The area of each hole, calculated as Pi times the radius squared (radius being half of the diameter), gives approximately 0.79 mm² per hole. To provide a ventilation area equivalent to the ten lines, approximately 570 holes are needed, as calculated by dividing 450 mm² by 0.79 mm².

Additionally, the AeroVent edition incorporates three ventilation lines on the bottom of each side. The total area for these lines is calculated as 3 times 90 mm times 0.5 mm, equating to 135 mm² per side, equivalent to about 172 holes.

The Light Edition's ventilated bottom is equivalent to about 598 holes. This configuration also supports top ventilation if both the glass and ventilated top options are selected.

This calculation highlights the efficient design of our ventilation system, ensuring optimal airflow with minimal structural disruption. Furthermore, it provides a clear and pristine view through the undisturbed glass, enhancing visibility and aesthetics.

Cross ventilation happens when air enters one side of the structure and exits through the opposite furthest side, facilitating airflow throughout the habitable volume and preventing stagnant air. While ventilation through holes on two opposite sides can promote some air circulation, strategic placement of vents, especially at the top and bottom, is crucial. Our jumping spider enclosures maximize airflow efficiency with strategically placed thin ventilation lines, enhancing the overall environment for the inhabitants.
