What is Masters Mix and why is it popular for gourmet mushrooms?

Masters Mix is a 50 50 blend of oak hardwood and soy hulls. It provides both structure and nutrition, so mycelium colonizes fast and fruits heavily. Pellet form makes it simple to hydrate and measure consistently across batches.

Do I need to add supplements to Fast Fruiting Pellets?

Fast Fruiting Pellets already include the soy plus hardwood ratio most hardwood loving species want. Many growers add nothing else. If you want to experiment, small amounts of wheat bran can boost yield, but too much can raise contamination risk.

Which mushrooms grow best on oak based substrates?

Oak substrates are ideal for wood loving gourmet species like oyster, lions mane, shiitake, reishi, and pioppino. Oak provides a steady lignin and cellulose food source that supports dense fruiting blocks and multiple flushes.

When should I choose straight soy hull pellets instead of a blend?

Straight soy hull pellets are best as a nitrogen rich supplement you mix with hardwood to form your own Masters Mix. They are also useful when you have local hardwood but need a consistent high nutrition add in pellet form.

Are straw pellets good for indoor gourmet mushroom farming?

Yes, straw pellets are a solid choice for oyster and other straw friendly species. Pellets rehydrate evenly, pasteurize well, and reduce chopping and dust. They are often used for bucket grows or smaller indoor production runs.

How does a bag shaker help a growing farm?

A bag shaker breaks up spawn and mixes substrate evenly in seconds. That improves colonization consistency, reduces manual strain, and cuts labor time. It is especially helpful once you are running multiple batches each week.

Why use a flow hood for inoculation?

A flow hood pushes hepa filtered clean air across your work area. That keeps airborne spores and bacteria off your grain and substrate during inoculation. Cleaner starts mean fewer lost blocks and more predictable harvest schedules.

Special Fruiting Mix

This popular new mix is ideal for many varieties of mushrooms that require a slower growth rate.

Special Fruiting Mix Pellets are designed to provide a great nutritional makeup for varieties with a longer colonization and overall growth cycle. Comprising 80% Oak and 20% Organic Wheat Bran, these pellets are blended and compressed into an easy-to-use form. This mixture provides an optimal growing medium for Shiitake, Maitaka, Reishi, and more. Pelletized simplifies labor and measurements typically involved in mixing sawdust and wheat bran or wheat midds.

When crafting your ideal substrate mix for many slow fruiting species, the two essential ingredients are 100% Red Oak Sawdust and Wheat Bran. These pellets offer a convenient alternative, being easier to handle, transport, mix, and measure than loose b. They also break down rapidly when water is added.

100% ORGANIC VERSION

Our Organic soy hulls are from fresh farmed soy beans. These hulls are prepared for us into pellets by our Amish pellet manufacturer. These are some of the same great craftsman that have supplied our customers with the hardwood oak pellets for some time now. These contain no oils or extra filler.

Each pellet will break down easy with water and just normal mixing. This makes them ideal for use as an ingredient in mushroom substrate, feed supplementation, and many more uses.

Soybean Hulls provide much needed nutrients to your ideal substrate mix. It is possible to grow mushrooms on many substrates, but if you want the best you want oak pellets, and soybean hull pellets for the ideal mix.

If you are making your own ideal substrate mix, you know there are two key ingredients. 100% Oak Sawdust and Soybean Hulls. These pellets are easier to handle, move, mix, and measure than loose hulls. They also break down just as the sawdust does from hardwood pellets by just adding moister and mixing.

More about Soy Hulls

Common names

Soybean mill feed, soybean mill run, soybean hulls

Soy Hulls are a by-product of the extraction of oil from soybean seeds. After entering the oil mill, soybeans are screened to remove broken and damaged beans, the soy beans are then cracked and their hulls are removed. These freshly removed hulls can than be used as nutritional supplementation in various ways. These are not intended for human consumption but can be an important part of the food chain since they provide dense nutrients to crops like mushrooms.

Soy Hulls are abundant and in 2018 farmers crushed over 2 billion U.S. bushels (120 billion lbs.) of soy beans. Since soy beans contain 3-5lbs of hulls per bushel, that means over 80 million pounds of soy hulls are produced each year. We can also ship larger quantity orders on pallet form to farmers.

As with our 100% Oak Mushroom Media pellets you can order these individually, or use our request a quote form for bulk orders of bagged Soy Hull Pellets.

During shipping some pellets may break down a bit and be dustier than other varieties of pellets, but this just makes their use easier with a faster breakdown on your end.
