Sakato PP Mushroom Grow Bags

Superior Quality From Japan’s Largest Mushroom Bag Producer

From the meticulously sourced polypropylene to quality tests at every stage of production, Sakato bags earn their reputation for quality and reliability with every harvest.

Creates a Controlled Growth Environment

Grow bags turn each block of substrate into its own separate biome, with either a 25 mm diameter 0.2-micron or 5-micron filter patch to create ideal airflow while filtering out contaminants and microbes. Sakato Grow Bags provide stability, control, ease of handling, and consistency.

The Right Bag For Each Task

Sakato mushroom grow bags are designed to meet the specific needs of different cultivation stages and environmental conditions, with each version tailored by filter type. 

0.2-micron filter bags are ideal for grain spawn production, providing a sterile environment that effectively blocks contaminants while allowing gas exchange, essential for the healthy development of mycelium. These bags are perfect for growers who need to ensure maximum protection against molds and other competing fungi. 

5-micron filter bags are best suited for substrate, offering increased airflow that supports faster colonization. These bags facilitate optimal oxygen levels, promoting robust mushroom growth.

Usage

• Fill the bag with desired material 
• Be careful not to spill any substrate on the upper regions of the bag as it can impact sealing
• Fold the gussets and roll neck of bag over contents to remove excess air
• Place in sterilizer
• Avoid overpacking sterilizer to ensure complete sterilization; leave space for steam circulation
