We investigate the key steps involved, including soaking, fluffing, and the importance of gentle handling to avoid damaging the moss's delicate structure.This comprehensive review assesses the accuracy of the advertised seven-quart expansion and addresses common pitfalls to avoid during the process. We also discuss the texture, volume, and overall usability of the expanded moss, offering insights into its suitability for various terrarium setups. Whether you're a seasoned terrarium builder or a beginner, this guide provides valuable information and practical advice to help you successfully utilize ExoTerra moss in creating a thriving and aesthetically pleasing habitat for your reptiles or amphibians.

Pros And Cons

Exo Terra Forest Moss Brick
  • Comes in a compressed brick for easy storage and transport.
  • Expands to create a large volume of usable moss (approximately seven quarts according to the packaging).
  • May not fully absorb the suggested amount of water (one liter).
  • Can become waterlogged and fall apart if not handled carefully.
  • Should not be squeezed to remove excess water as this can cause soil to disperse and affect the moss's texture.
  • Squeezing the moss can result in a matted, less usable consistency.

Unboxing and Initial Impressions

The ExoTerra moss arrives compressed into a brick, a surprisingly dense package. The label indicates that this moss is collected from Asian forests and is different from New Zealand or US varieties. Each package contains two bricks, offering a substantial amount of moss once expanded.

The compressed brick is remarkably compact, showcasing just how much the moss will expand. The packaging promises seven quarts of expanded moss once hydrated, a claim we will investigate further during this review.

The Expansion Process: A Time-Lapse

The expansion process is significantly sped up in the video, but it's clear that submerging the brick in water is key. The presenter mentions using approximately two liters of water, more than the suggested one liter, to ensure complete saturation. Periodically, the brick needs to be turned to address dry spots and aid even hydration.

During the time-lapse, you can see the moss gradually expanding. Note that the presenter frequently turns the brick to ensure even moisture absorption throughout the expansion process. The final size and volume should reveal if the product meets the manufacturer's claims.

Fluffing and Final Volume

After the initial soaking period, the moss is removed and gently fluffed. This step is crucial for achieving the advertised seven quarts of volume, as it separates the moss fibers and allows for better air circulation. Avoid squeezing the moss to remove excess water as this damages the texture and structure.

The final step involves fluffing the moss. This step helps the moss regain its texture and fluffy feel. Once fluffed, the moss is ready for use. The result is a significant increase in volume, making the seven-quart claim seem quite realistic.

Important Considerations and Conclusion

Avoid squeezing the expanded moss to remove excess water. Squeezing not only causes the moss to become matted but also pushes soil from the base of the brick throughout the moss, diminishing its aesthetic quality. Gently fluffing and spreading the moss is the best approach.

The ExoTerra moss, despite the initial compression, successfully expands to a usable volume. While the manufacturer's claims are largely accurate, the expansion process might take longer than initially anticipated, and patience is key. The final product is a fluffy, versatile substrate, ideal for various terrarium setups.
