WHICH COMPOST?
Coir compost is great for most terrarium plants. You can buy coir compost in dry, block form. Without water, coir compost is very light and compact, useful if you’re ordering online. Once you add water, the compost block increases in size to fill a bucket! The coir compost block will usually provide enough compost to plant between three and five terrariums, depending on their size. You can cut pieces from a block of coir compost and save the rest for another time.
