how “Mushroom Grow Kits” only say they fruit once or twice on the box, but wild/cultivated mushrooms usually don’t stop.

Question

I’ve seen a mushroom grow kit from Back to the Roots. It says that the vacuum sealed bag is mycelium and you can follow instructions to get it to fruit once, maybe even a second time on the other side of the bag. Why does it imply that it stops there? I thought mycelium continues to spread and fruit periodically?

Thank you in advance for the insight!

Edit: Awesome explanations guys, thank you again

Answer 1

Closed ecosystem. No new nutrients are being introduced and waste and by-products aren’t being removed like it happens in nature.
