Product description





Keep plants and animals growing strong and healthy by supporting your terrarium with all-natural coconut husk substrate.
When it comes to pets there’s few things more fun and exciting than raising snakes, turtles, frogs, and spiders. But these unique animals require a little extra care, especially when it comes to their terrarium balance. That’s why we created this natural coconut husk fiber substrate that helps you maintain a healthier, cleaner environment, so they can feel more at home, and you can keep indoor tanks smelling fresher and looking cleaner far better than wood chips, rocks, or other poor-quality substitutes.
Increased Terrarium Humidity
A natural substrate for plants and animals, coconut husk fiber substrate stimulates natural digging and burrowing behaviors. It also helps maintain a warmer tank environment which is important for reptiles and amphibians. This increased humidity allows them to maintain their body temperature more effectively, which can help increase their natural energy levels. Important for growth, sustainability, and overall animal happiness.

Works fantastically
This is a giant pain in the ass to chip away at (my most success was the back end of a hammer) however, that *makes sense* because it is *compressed* so… like… be aware of what you’re buying?? (Not looking at the other commenters on here >_> )Anyway! Once it’s been reconstituted, it’s super soft and lovely and it lasts soooooo long.Super awesome.Oh, it was a total mess lol (I broke it down in a tub, slowly pulling it apart and mixing it with water)

Highly recommend
This stuff is amazing for my ball python enclosure. It holds humidity super good and looks really nice. You definitely get your moneys worth since itâs condensed. Little messy to work with but not too bad. Surprisingly smells kinda good too, outdoorsy.

This was my first time buying the coconut brick and Iâll never buy loose substrate again! Great price point and more than enough for my snake. Holds humidity well and smells good

Easier to break up than the smaller bricks
The large brick was easier to break apart than the smaller bricks, so when adding water I didn’t have to add as much water to get it reconstituted. Therefore I didn’t have to let it dry out at all. I was able to put it right in our tortoises pen as it was not sopping wet. Saved lots of time.

Not too shabby
Snake seems to enjoy it. Kind of messy but it seems to best bang for your buck. Would buy again
Amazon Customer –
Great product
Holds humidity really well and perfectly fills a 70 gallon tank (ball python) … I will buy this routinely

Great quality substrate
I got this for my new 6x2x2 enclosure for my boa and I wasn’t positive if it would fill to enough height that I wanted but it was perfect!I put the giant brick into a tub and watered it and broke it up in chunks until it was all dirt like looseness. Took maybe 20-30 mins of tilling it before I felt it was fully hydrated, just be warned it’s extremely heavy once it’s expanded.I will be buying this again down the line, but it’s holding humidity and doesn’t have any sharp bark chunks, all soft small coconut dirt.

It’s okay as in like good stuff but it’s a pain in the backside as it’s a solid block when it comes. I am new to this stuff for my tortoise so I didn’t know it would arrive as like I said a solid block haha
