Master's Mix pellets combine the classic 50/50 formula, 50% oak hardwood and 50% soy hull, in a single pellet. There is nothing to weigh, blend or supplement: add water, bag it, sterilize and inoculate.

Sold in 40 lb bags or by the 2,000 lb pallet. Because both ingredients are in every pellet, each batch you hydrate comes out at the same ratio, which matters when you are making blocks on a schedule.

Why growers use Master's Mix pellets

The formula, pre-built

No separate sawdust and hulls to source, store and measure.

Consistent

One ingredient means one ratio, every batch.

Compact

Dry pellets store in far less space than loose sawdust.

Making Master's Mix blocks

1Hydrate

Add water and let the pellets break down into fluffy sawdust. A firm squeeze should release only a few drops.

2Bag it

Fill filter patch grow bags, keep the patch clear of wet substrate, then fold and clip the tops.

3Sterilize

Pressure sterilize at 250 F (15 PSI) for about 3.5 hours. Bigger bags and fuller loads may need longer.

4Cool and inoculate

Let the bags cool to room temperature, then add grain spawn in front of a flow hood.

Sterilize, do not pasteurize. Master's Mix is too nutritious for open tubs or pasteurization. It needs a full pressure sterilization and sterile inoculation.
