5 lb Sterile Grain Bag – Premium Corn

Popcorn Grain. Pressure Sterilized. Ready to Inoculate.

Now Includes FREE Injection Port
Our 5 lb Premium Corn Sterile Grain Bag is crafted using high-quality organic popcorn, carefully simmered and hydrated for optimal moisture content. Pressure sterilized in SH Scientific autoclaves for consistent, reliable performance.

Key Features

  • Premium organic popcorn grain
  • Simmer-hydrated for balanced moisture content
  • Sterilized 2.5 hours in SH Scientific autoclaves at 15–17 PSI
  • Large kernel structure for strong colonization
  • Vacuum-sealed for extended shelf life and sterility protection

Why Choose Corn?

Popcorn grain offers durable kernels that hold structure well during colonization. Its size makes it easy to inspect, shake, and break apart — making it a favorite for both beginners and experienced growers.

What’s Included

  • Unicorn 3T bag with 0.2 micron filter
  • 5 lb hydrated organic popcorn grain
  • Microppose self-healing injection port
  • Vacuum sealed inside a secondary 4 mil protective bag

Quick Start Guide

Step Instructions
1. Inspect Ensure the bag is sealed and the filter patch and injection port are intact.
2. Inoculate Clean the injection port with alcohol. Inject 8–10 mL of liquid culture or spores using a sterile syringe.
3. Shake (Optional) Once 20–30% colonized, gently break up the mycelium to distribute growth.
4. Incubate Let colonize at 70–75°F in a clean, dark space. Most bags finish in 10–18 days.
5. Use or Store Once fully colonized, use immediately or refrigerate for up to 2 weeks before transferring to bulk substrate.

Storage Guidelines

  • Store between 45°F and 70°F
  • Keep sealed until ready to use
  • Use as soon as possible for best performance
  • Do not freeze

B.P.

the grain: i picked milo took off nicely, 2 cc’s per bag, 5 bags per syringe. Works very nice, bags will be done withing a week. I should break and shake right now but, I think ill wait another week or so. As for the bulk substrate, looks great ive been keeping it in our storage room, its super chilly in there. And, it should work great when the time comes. Personally, ive never had issues with any of the bags ive purchased. I hardly inoc in my SAB anymore, as theres no need I just flame sterilize the needle, and inoculate.
