Espresso

[lilly_sand99]

So Starbucks (or at least the one I work at) does this really cool thing were we take the ground espresso and bag it for people's gardens. The espresso grounds are super fine and it looks almost like the coconut dirt (can you tell I'm bio major?)

Would it be ok to mix in the espresso grounds with my current substrate?

I wouldn't do it. It may be acidic or otherwise harmful to the tortoise's shell. It would be fine to mix into your garden or worm pile, but not substrate.

From my understanding, used grounds have lost their acidity to the coffee. They are very high in nitrogen so you could get some composting action going in the enclosure.
I do not know if the caffeine residues could be very toxic.
Better to put them in your garden! They really make stuff grow.

Thank you!

Another thing is that mold readily grows on damp grounds. You want a substrate that resists mold.
