Sponge mushroom caps create dynamic microhabitats within bioactive enclosures, offering isopods and springtails shelter while simultaneously enriching substrate as they decompose. The porous structure encourages natural foraging and exploratory behaviors, mimicking the forest floor environment these detritivores inhabit. As the cap breaks down, it releases nutrients that support microbial colonies and plant growth—essential components of a balanced bioactive system. A distinctive addition that merges function with aesthetic appeal.
