Frequently Asked Questions
Q: How hard is this to install in my garage?
A: Installation is similar to adding an outlet for a dryer or electric car charger. Most electricians can wire it in easily, and the unit comes ready for a standard 30AMP connection.
Q: What’s the sterilization process for grain bags?
A: Add 4–4.5 gallons of filtered or RO water, load the grain bags in stacks, tighten the clamps, and start the cycle. For a full load, we recommend 121°C for 3-3.5 hours.
Q: How long does a cycle take from start to finish?
A: Most cycles take about 4–4.5 hours total, including heat-up and cooldown. You can use natural cooling for a longer cool-down period or computerized slow venting for faster turnaround.
Q: How much can I sterilize at once?
A: This unit can handle up to 48 × 3 lb grain bags, 24 × 5 lb substrate bags, or 12 × 10 lb substrate bags per cycle.
Q: What do replacement parts cost?
A:
- Silicone Gasket: $60
- Heating Element: $249
- Temperature Sensor: $99
- Control Boards (Call to order)
Q: Why buy from us?
A: Many competing units ship from overseas with long lead times. We stock our autoclaves in the U.S. for faster delivery, provide in-house technical support, and work with the factory on performance upgrades that improve real-world results for mushroom growers.
