Now you can have the moss covered background you always dreamt of. Dusk Tropic has developed a system for backgrounds in terrariums, vivariums and other growing cabinets. The concept is called IIS and stands for Integrated Irrigation System.

This system is totally self watering and suits all kinds of epiphytic plants. There are several modules and branches that you can add to get a more complete system that fits your taste. These modules and branches are easily attached to the background. Once attached they are also part of the irrigate system. EpiWebs structure and other characteristic, together with the specific moss mix makes this system 100 % effective. It gives mosses, ferns, orchids and other sensitive tropical species the optimal growth environment.

The background modules are complete and ready to attach in all kind of terrariums with a waterproof back piece. There are silent pumps that suits the system.

The system can be built in any sizes and therefore be used in building "green walls". Please enquire of non-standard sizes.

There is also a range of kits for the complete range of Exo Terra vivaria.

Please note we only have limited stocks of panels, modules, liana and kits so delivery can take up to 3 - 4 weeks.
