50/50 CVG – Pasteurized Bulk Substrate

Premium Mushroom Substrate – Sterile, Balanced & High-Performance Bulk Mix

SporeAura’s premium mushroom grow bags feature a professionally formulated bulk mushroom substrate, engineered for superior yield, consistency, and ease of use. Designed for reliable performance, this sterile grow bag delivers a perfectly balanced blend of 50% vermiculite and 50% coco coir, enhanced with gypsum to stabilise pH and support optimal mycelium development.

Pre-pasteurised and fully hydrated, this ready-to-use substrate eliminates preparation time while ensuring a clean, contamination-resistant environment. Each unit is sealed in a high-quality filter patch bag, allowing proper gas exchange while maintaining the sterility expected from professional mycology supplies.

Produced using advanced cultivation equipment, every bag undergoes automated pasteurisation at over 75ºC for 130 minutes, ensuring consistent quality and reliable results. The substrate can be stored in refrigeration for up to 14 days or frozen for extended storage, offering flexibility without compromising performance.

For best results, simply mix with fully colonised grain spawn to create an ideal bulk growing environment. Compared to fruiting directly from BRF cakes, this method significantly enhances yield potential and overall growth performance—making it a preferred choice for cultivators seeking larger, more efficient harvests.

Built for consistency, sterility, and ease of use, SporeAura’s mushroom grow bags provide a high-quality substrate solution that supports strong, healthy growth and maximises cultivation success.
