Grow bags
Mushroom Van grow bags are prepared for home growers who want the process to feel clear, careful, and possible.

A grow bag is a prepared substrate block with live mycelium, timed close to fruiting for a practical first harvest.
Keep it clean, cut or open as instructed, mist when needed, and watch airflow and humidity.
Use the first harvest to learn the fruiting rhythm before moving into grain, substrate, and repeat batches.
For bigger runs, pair cultures with prepared bags and ask for timing support so batches do not all arrive at once.
