Whole Rye Berries Mushroom Grain Spawn

Rye Grain Instructions:

Sold in 1lb, 2lb, 3lb, 4lb,  5lb quantities.

  1. Soak grain for 24 hours in cold water.
  2. Add any additional nutrients you wish (optional)
  3. Simmer in hot water until grain puffs up with water (Normally 30 minutes)
  4. Strain and dry grain until it is mostly dry on the outside.
  5. Sterilize the grain for 120 to 180 minutes between 15 and 22 psi.

Whole Rye Berries – Mushroom Grain Spawn

Planet Spore’s rye berry grain spawn bags consist of locally sourced 100% organic natural premium rye berries which are commonly regarded as the best grain spawn for mushroom cultivation. Our grain spawn is free of chemicals or any additives.

Rye Berry Spawn Features

Why Choose Rye Over Other Mushroom Spawn?

Rye grain has been the go to choice for mushroom cultivation since the 1970’s. Rye gets a bad reputation because it’s rather challenging to prepare, but once mastered, rye berry mushroom spawn is the highest performing spawn available. Rye has many shell layers that can prevent full sterilization, in order to get around this it must be sterilized at higher temperatures and for longer than other grains like oats and millet. 

Rye is known for its resistance to contamination and is able to retain the most water and has the highest nitrogen levels when compared to other grains. Its elevated water retention and high nitrogen levels not only provide the best nutrients for growing mushrooms but also lengthen your mycelium’s life, allowing for dense higher yielding second and third flushes.

Applications of Rye Berry Spawn Bags

Inoculation of Rye Spawn with Mushroom Spores or Culture

Once fully prepared, sterilized, and cooled, rye berry mushroom spawn can be inoculated with mushroom spores or mushroom culture to promote the growth of mycelium and ultimately mushroom fruiting. 

This process is quite straightforward, simply inject spore solution, liquid culture solution, or drop mushroom agar culture into the rye berry spawn bag, then seal it. Keep the bags in a clean, warm, dark room for 2 to 6 weeks to achieve full colonization. For more detailed instructions check out our step-by step mushroom growing guide.

Inoculation of Rye Spawn by Colonized Grain Transfer

You may also perform what is called a grain transfer. A grain transfer is taking a colonized grain spawn bag and transferring it to more sterilized grain spawn bags to promote further propagation of mushroom mycelium growth. 

Generally you can transfer one bag of fully colonized grain spawn to five to ten bags of sterilized grain (depending on the weight of the initial bag). We have a detailed grain to grain transfer guide here.

Mixing Colonized Rye Spawn with Bulk Substrate

After rye mushroom spawn bags have fully colonized you may move to the next step of the mushroom growing cycle which is preparing and mixing bulk substrate. This step involves mixing colonized mushroom spawn with a substrate of your choice. For optimal nutrients for mushrooms try our in house bulk substrate. 

We recommend mixing a 3 parts substrate to 1 part mushroom grain spawn ratio for the best bulk substrate results. Similarly to grain colonization, the colonized grain spawn must colonize the bulk substrate as well (this step is called the incubation phase). Once fully incubated the bulk substrate is ready to be pushed to the fruiting phase.

PLEASE NOTE – YOU WILL NEED TO PASTEURIZE/STERILIZE YOURSELF
