Design and Features

The Zoo Med New Zealand Sphagnum Moss comes in two sizes: the 80 cubic inch block, and the 150g block.

This sphagnum moss comes from New Zealand and offers excellent absorbency to provide a humid environment for your reptilian pet.

This long-lasting moss can be washed and reused a number of times.

Sustainable methods are used in the harvesting of the moss, which is able to hold up to twenty times its weight in moisture.

This moss is fantastic for natural bio enclosures, where you want to have live plants.

The moss can be used in a hide to create a humid hide to assist with shedding to helping boost humidity levels to ensure your reptile remains happy and healthy.

Parts and Accessories

While boosting humidity to make your pet feel comfortable and ensure their overall health and well-being, you need to be able to measure your humidity levels accurately.

The Zoo Med Labs Digital Thermometer and Humidity Gauge enables you to quickly read your humidity levels, so you can see how the moss is working and whether you need to mist or reduce your moisture accordingly.

The gauge comes with a waterproof probe, making it suitable for use in a humid environment.

Usage and Maintenance

When the Zoo Med New Zealand Sphagnum Moss arrives, it will be compressed in a bag.

When you wet it, it will expand. All you have to do is soak the moss in a bucket of water, give it a little squeeze now and then to help it absorb the water.

You want it just damp, so you can wring it out before you add it into the enclosure. You don’t want it soaking wet.

The moss is excellent when used to cover another substrate, creating a carpet like layer similar to what would be found in the wild.

Another substrate below, such as coconut husk, can provide the burrowing and digging substrate your reptile needs.

Place the moss around your water bowl, so it can absorb any spills.

You can clean and reuse the moss quickly and easily.

How to Clean

To clean and reuse the moss, remove it from the enclosure and put it in some clean water, similar to when you first prepared it. Swirl it around a bit and wring it out.

Follow this process a few times until the water runs clear and the moss smells clean.

Remove feces daily to keep your enclosure fresh and clean.

How Often Must You Replace?

This moss is designed to be used up to four times before you need to replace it with new moss.
