Sterilised Mushroom Grow Bag 1300g with Injection Port | 123GrowBag
Looking for a clean, no-fuss way to start your next cultivation project? The Sterilised Mushroom Grow Bag 1300g with Injection Port combines a sterilised grain base and a nutrient-rich bulk substrate in one sealed bag. No transfers, no extra preparation — simply inoculate and let the mycelium do the work.
An all-in-one sterilised substrate grow bag
Produced in controlled batches for consistent cleanliness and stable availability, this ready-to-inoculate grow bag holds 1300g of prehydrated substrate (60–65% moisture). The blend pairs a sterilised grain base, such as rye or sorghum, with a bulk mix of coco coir, vermiculite and gypsum to support steady colonisation. A self-healing injection port and a 0.2 µm microfilter handle inoculation and gas exchange in a single, sealed unit.
Why growers choose this grow bag
- Less hands-on work: the grain and bulk substrate come combined, so there’s no need to mix or transfer between containers.
- Lower contamination risk: the sealed bag, microfilter and self-healing port keep the substrate protected during inoculation.
- Consistent results: controlled batch production keeps moisture and composition stable from bag to bag.
- Approachable setup: a practical option for beginners and seasoned hobby cultivators who prefer minimal equipment.
- Reliable availability: continuous production supports fast order fulfilment.
Inoculation is done directly through the injection port using your own spore syringe or liquid culture. The bag is intended as a cultivation supply and is supplied without spores. You can pair it with related items from our Grow Supplies range, or browse other Mushroom Grow Bags to suit your project.
