What a mushroom kit is doing
A culinary grow kit is usually a block already run through with mycelium. Fruiting is a change in air and humidity, not photosynthesis.

Cultivation
What domesticated wood-decayers need in order to fruit, written for readers rather than for a grow room.

Green mold on a block is not a moral failure. It is other organisms winning the same substrate race your crop was running.
What spawn is
Spawn is living mycelium on a carrier — often grain — used to inoculate a larger substrate. It is not a seed, and it is the quiet middle chapter of cultivation.
