This substrate gave our reptiles mites. I’m furious. This is going to be such a pain to treat. We didn’t introduce any new animals or any new hides. All we did was change our substrate. Every reptile we have who was given this substrate has mites now

Product is not as shown

I choose this because it appeared blocky, but it is actually very fibrous. I will not be getting this again.

All fiber, no chunks

After hydrating the block, it was all fibers and very few chunks. I really hope this doesn't cause issues for our BP... dire need of a bedding change so I need to go with this.

Know the actual size of your pet BEFORE you purchase substrate.

My daughter and I prepared for weeks before purchasing her Pacman frog. The terrarium was set-up, succulents were planted, temperature and humidity were spot on, even the mealworms were alive and waiting. My daughter told me that a Pacman frog is about as big as my palm, and to make sure that I purchase substate large enough so that he/she can borrow. Which I did, and substrate was soaked, spread and misted each day until our new friend arrived. Turns out that a Pacman will grow to be the size of the palm of my hand!! Lol! Our gal or guy was only about 3/4” cube! New substrate ordered!! We’ll save the remaining bricks for when our frog is much bigger!

Not What I Thought

So, the fault may be mine in not knowing what the difference between husk & fiber? but this stuff did not work for my needs which was for my worms. It was 0 stars for that. Another brand was much better. The chunks are large and not at all like the stuff I was used to getting which was more like dirt. I would say it was considerably less broken down then what i thought & the worms dont even seem to break it down & they make everything disappear in short order. So anyone looking for worm substrate, this is the wrong kind.

This is great when mixed with Coco soil and moss. Yes there are some big pieces but that's what you're getting. This isn't fine like Coco soil. If you want fine get that, if you want definition to your habitat, get this and mix it with soil and moss.

Overall a good choice!

This was my first time using compressed substrate and it absorbed SO quickly! It was very easy to do and the instructions were very clear. I just don't like how stringy it is. I wish it were more like chips because the stringy husk gets caught in my snakes' mouths a lot.
