Pre-sterilised Bulk Substrate 2kg with Self-healing injection port

Sterilised Mushroom Substrate, the perfect choice for mushroom cultivators seeking convenience and guaranteed success. Our sterilised substrate is meticulously prepared using high-quality organic materials, eliminating the need for time-consuming and potentially risky sterilisation processes. Using our Sterilised Mushroom Substrate is simple and straightforward. Just open the package, transfer the substrate to your desired growing container, and inoculate it with your chosen mushroom spawn. With the sterilisation process already taken care of, you can focus your efforts on providing the right conditions for optimal mushroom development.

Buy this product when your spawn is almost fully colonised and is ready ready to go to bulk substrate.

This product is intended to be used immediately upon arrival to minimise the chances of contamination.

Very rough guide:

20-24 Litre tub accommodates 2kg (Grain + Substrate)

30-45 Litre tub accommodates 3 - 3.5kg (Grain + Substrate)

45-60 Litre tub accommodates 4 - 5kg (Grain + Substrate)

We recommend 50% Substrate to 50% Grain spawn ratio.

GENERAL ITEM DESCRIPTION

The bags are assured 100% contaminant-free due to their sterilisation process of 2.5 hours at 15 psi in a commercial autoclave. In the unlikely event that you see contamination in your bag that may be due to shipping, please send us a photo within 2 weeks of receiving the item for a full refund or replacement.

Your bags are made to order; please allow 2 to 3 days of handling time.

Weight: 2kg

Your kit includes:

• 100 % Substrate (Sterile and prepared at field capacity)

• 1x Self-healing injection port

• Alcohol swab

How to avoid contamination: Take the bags out of their packaging as soon as possible, and keep them at room temperature, away from direct cold/heat sources. The bags need to breathe and should not be kept where there is no free airflow. Keeping the bag in a closed environment will result in anaerobic contaminants thriving and making the bag mouldy. We recommend that the bags be used as soon as possible to minimise the chances of contamination or within 2 weeks. Work in front of a flow hood or a still air box using a completely sterile workspace. Mix at least 15% grain spawn or higher of your desired species and mix it thoroughly in the bag and let it colonise. Incubate at 24°C in a dark spot and keep all the bags at a distance from each other to avoid excess heat, which leads to contamination. A temperature lower than 24°C makes mycelium grow slowly, which could give a chance to competing organisms to flourish. Temperature above 24°C favours competing for organisms than fungi which increases likely hood of contamination.

1. Keep the bag again for a week in a dry and dark spot at 24-25°c.

2. Ready to fruit as per your mushroom specie- Some are top fruiting, and others are side fruiting.

The recommended time frame for use once received max 2 weeks.
