CVG Monotub Mushroom Bulk Substrate Coco Verm Gypsum

$35.00$280.00 inc. GST

Description

Our 2 kg pre-sterilised, ready-to-use CVG Monotub Mushroom Bulk Substrate is ideal for mushroom monotub cultivation. This substrate is hydrated to field capacity, ensuring optimal moisture content for mushroom growth. This is the most popular substrate used for monotub cultivation.

 

Coco Coir + Vermiculite + Gypsum (CVG) Substrate: CVG is a popular bulk substrate that combines coco coir and vermiculite. These components offer excellent water retention with minimal nutrition. Gypsum is added for its sulphites and calcium, which supplement the mix and help keep the substrate aerated. Since mushrooms are 90% water, this substrate’s ability to absorb much water is crucial for sustaining mushrooms until the first flush. Sterilisation of the substrate dramatically reduces the risk of Trichoderma contamination, a common issue for first-time growers. However, it’s important to note that contamination isn’t completely avoidable if your growing area and processes aren’t clean. Most nutrition for mushroom growth comes from grains added during inoculation, making a higher grain-to-substrate ratio beneficial for substrates like CVG. Rye is theoretically the best-suited grain for this substrate, balancing the missing nutrition, but it tends to dry out quickly and can be challenging for beginners to colonise. Millet is a more manageable alternative, offering easier handling for first-time growers. This CVG Monotub Mushroom Bulk Substrate is often called the best Monotub Substrate.

 

Source and Quality of Coco Coir

Our coco coir is sourced from a supplier that washes it free of salts and does not inoculate it with Trichoderma, Leading to a faster colonisation and fewer chances of contamination.

  1. Take the bags out of it’s packaging as soon as possible, and keep them at room temperature, away from direct cold/heat sources.
  2. Do not store uncolonised bags in the fridge; only fully colonised bags can be kept to slow down the fungus and delay fruiting until ready.
  3. We recommend that the bags is colonised as soon as possible to minimise the chances of contamination or moisture loss.
  4. Work in front of a flow hood or a still air box or in a room with no air movement with the workspace adequately sanitised.
  5. Mix at least 15% grain spawn or higher of your desired species, mix it thoroughly in the bag, and let it colonise.
  6. Incubate at 22-24°C in a dark spot and keep all the bags at a distance from each other to avoid excess heat.
  7. Temperatures lower than 20°C make mycelium grow slowly, which could allow competing organisms to flourish. Temperatures above 24°C favour competing organisms rather than fungi, which increases the likelihood of contamination. Temperatures around 32-34°C will kill the mycelium.
  8. Prioritise airflow over, keeping the bag in a dark spot. If there is no air current during colonisation, the CO2 buildup inside the bag will not be able to be expelled out of the air filter patch. Excess CO2 buildup will suffocate mycelium, leading to slow growth and mycelium producing excess metabolite as a sign of stress, which changes the pH of the substrate and makes it easier for contamination to thrive.
