This is a REFILL KIT for the popular HydroShroom Mushroom Growing System.
The HydroShroom is the first consumer mushroom growing system that operates on the theory of hydroponics. Drawing moisture into their mycelial "roots" from the nutrient-enriched hydroton base, your mushrooms will grow larger fruits, and grow them fast! Look forward to multiple flushes with every cake cycle.

The HydroShroom is a fully featured mushroom growing kit that comes with everything you need to grow edible mushrooms (spores not included).

Once the HydroShroom is assembled, it is designed to reproduce the optimal environment for growing fungi. With controls giving you the ability to adjust moisture, temperature, and air content, the HydroShroom acts as a self-contained, AUTOMATED mushroom ecosystem.
