Filters with a larger pore size provide increased air exchange, but there’s a higher chance of competitor organisms getting in. Mushroom growing bags are plastic bags specifically designed for growing mushrooms. They make the mushroom growing process much easier and often have one or more of the following features: Gusseted They come in various shapes and sizes with a range of filter pore sizes to suit all mushroom-growing techniques. Filter patch mushroom growing bags are readily available online. When gusseted bags are filled with a substrate, they become sturdy stand-up bags with a strong, flat base. You can utilize mushroom growing bags in several ways, allowing you to use them for most mushroom species.

Lay flat tubing is a long, continuous plastic tube made from Polythene or Polypropylene that usually comes in a large roll. With repeated use, the plastic gets weaker, and multiple sterilizations can affect the filter, increasing the chances of contamination. Why Use Mushroom Growing Bags? The material used for these bags is polyethylene, and they’re not autoclavable and don’t have breathable filter patches. But to initiate mushroom pinning, you’ll need to expose the mycelium to more fresh air by cutting holes in the bag or opening the top. Can You Reuse Mushroom Grow Bags?

Many Asian mushroom farmers use inexpensive, cylindrical polyethylene bags without filters, usually 6 to 7 inches (15 to 17 cm) wide and about 12 inches (30 cm) long. They offer different filters for spawn and substrate, and, like filter patch bags, you can choose from a range of bag and filter sizes. Open the top for top-growing species like king oysters or enoki, cut holes in the sides for side-fruiting species like lion’s mane or remove the bag entirely for species like shiitake. Thus, it’s best to use larger filters for faster-growing species to help reduce the chances of contamination that come with a larger filter size. 3. Bag Size Filter patches come in various shapes and sizes, and their pore sizes range from 0.2 to 5 microns.A smaller pore size means fewer contaminants, but there is also less fresh air exchange. Polypropylene

If you’re pasteurizing your substrate, you can use any sturdy plastic bag with holes poked in for air exchange. 2. Filter SizeMany bags also have filters that allow the mycelium to breathe while keeping moisture inside and contaminants outside. What to Look for When Choosing Mushroom Growing Bags One of the first decisions mushroom growers have to make is what type of containers to use, bearing in mind the functionality required.
