Our Four-Pound BRF Cake – The Big Daddy of the BRF Family
For those who want to go big, our four-pound all-in-one BRF cake is the ultimate choice. This new and improved version makes cultivation easier than ever—no need for fruiting chambers, monotubs, misting, or cutting. Simply inject the bag and forget it.
Made with a superior blend of organic brown rice flour and vermiculite, this PF-Tek substrate provides the perfect environment for a variety of mushroom species. With thousands of inoculation points, the increased volume allows for faster colonization and yields reaching up to 1,000 grams or more.
Using it couldn’t be simpler: inject the sterilized bag, keep temperatures stable, and store it in the dark until fully colonized. Once colonization is complete, introduce light, and that’s it—no extra steps required.
Each four-pound bag is built to the highest standards, featuring a 0.22μm filter patch for optimal airflow and a medical-grade self-healing injection port for straightforward inoculation. Every bag is sealed and sterilized at 121°C for a minimum of 120 minutes in a computer-controlled autoclave, ensuring a perfectly clean and ready-to-use substrate.
For those looking to maximize their harvests with zero effort, the four-pound BRF cake is the big boss—a high-quality, all-in-one grow bag designed for outstanding results with minimal effort.

This was my first time growing, and I was nervous, but this bag made it super easy. Just injected my spores, waited, and boom—growth everywhere! Highly recommend.

The bag was well-packed and arrived on time. My spores took a bit longer to colonize, but that might be due to my storage conditions. Still, great quality and easy to use

“I’ve tried a few grow bags, but this one was the best so far. The moisture content was just right, and my mycelium took off fast! No contamination issues either. Will definitely order again!
