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

For oyster mushroom grow kits my friend brought some with her to college so she could have fresh mushrooms, they fruited multiple times over the full 2.5 years before she left for her clinicals, and when she left they were still viable so she passed them on to an incoming student who wanted them. She did add new growth media as needed in order to maintain nutrients, but if you care for it, you can fruit them as long as you like.
