Hey y’all, I apparently don’t know how to do math, lol. So, I’m building an 8’x4’x2’ indoor enclosure for my Russian. I’m planning on doing 12” of packed coconut coir as substrate, which means I’m likely going to have to buy in bulk. How much substrate do I need to buy? Or like, honestly, even if someone could tell me the relative volume of a hydrated, packed down coconut coir brick that would be super helpful. Thank you!
