Unicorn Grow Bag with Injection Port

The Unicorn Grow Bag with Injection Port is a sturdy grow bag designed for the controlled cultivation of mushrooms. The bag features a self-sealing injection port. This allows you to add a spore solution or liquid culture without having to reopen the bag. The built-in Tyvek filter facilitates gas exchange during the development of the mycelium.

A Unicorn Grow Bag combines an injection port and a breathable filter in a single, practical grow bag.

The grow bag is made from strong polypropylene and, according to the product information, can be autoclaved up to 121 °C. The Grow Bag is available in two sizes: 4T and 10T. This allows you to choose the size to suit the amount of substrate you wish to work with.

What is a Unicorn Grow Bag with an injection port?

A Unicorn Grow Bag is a specialised bag for colonising substrate with mushroom mycelium. The injection port allows the bag to be inoculated without opening it. This helps to minimise the substrate’s exposure to the environment during this stage.

At the same time, the Tyvek filter ensures gas exchange. This is important during colonisation, as the growing mycelium needs to be able to breathe.

Why choose a grow bag with an injection port?

The injection port makes controlled inoculation easier. You do not need to open the cultivation bag to do this. The port seals itself again once the needle has been removed.

How do you use a Unicorn Grow Bag?

Fill the Grow Bag with the desired substrate. Sterilise the substrate if required by your cultivation method. Once cooled, the bag can be inoculated via the injection port with a suitable spore solution or liquid culture.

Then allow the bag to colonise under suitable conditions. The filter facilitates the necessary gas exchange without you having to open the Grow Bag.

What should you bear in mind during use?

Working cleanly is important when inoculating and colonising the substrate. Ensure your hands, materials and work surface are clean. Keep the injection port and filter intact during use.

Contamination is a key concern when growing mushrooms yourself. Read our guide on mistakes and lessons learnt when growing your own for more background on common cultivation problems.

Who is the Unicorn Grow Bag suitable for?

The Unicorn Grow Bag is suitable for both novice and experienced mushroom growers. The 4T is practical for smaller projects. The larger 10T offers more capacity for growers working with larger quantities of substrate.

Which size is best for you depends mainly on your growing method and the amount of substrate you wish to use.
