MGP Plus - Growth Promotion + Substrate Vitality

MGP Plus Mushroom Growth Promoter + Trichoderma Defense

MGP Plus is an advanced mushroom growth promoter designed to increase mushroom yields while helping protect substrates from the damaging effects of Trichoderma harzianum contamination. Formulated with a powerful blend of 10 beneficial microorganisms, MGP Plus supports vigorous mycelial growth, healthier substrate ecology, faster colonization, and larger, more consistent flushes.

Unlike standard mushroom supplements, MGP Plus combines mushroom growth promotion with biological contamination resistance. The included Bacillus microorganism forms a protective biofilm that helps reduce the risk of Trichoderma incursion, making this an ideal solution for mushroom growers dealing with recurring green mold contamination issues.

Perfect for hobbyist cultivators, monotub growers, commercial mushroom farms, and gourmet or medicinal mushroom cultivation, MGP Plus helps extend substrate longevity while improving overall fruiting performance.

Benefits of MGP Plus

• Increases mushroom yields and flush potential
• Supports aggressive, healthy mycelium growth
• Helps protect substrates against Trichoderma harzianum
• Encourages faster colonization and fruiting
• Extends substrate and cake lifespan
• Improves overall substrate microbiology
• Ideal for monotubs, bags, bulk substrate, and commercial grows
• Suitable for gourmet and medicinal mushroom cultivation

How MGP Plus Works

The beneficial Bacillus strain in MGP Plus creates a natural biofilm barrier that helps defend against contamination from Trichoderma. Because this protective layer takes approximately 8 days to establish, MGP Plus should be applied during the spawning-to-bulk stage for best results.

Directions for Use

Liquid Application

• Add 2 grams of MGP Plus to a 1L spray bottle
• Store in a cool area away from direct sunlight
• Use within 6 months for best performance
• Mist substrate thoroughly while mixing spawn with bulk substrate
• Use at least 8–10 sprays per 400g of bulk substrate material

Dry Application

• Add 1 gram directly into substrate and mix thoroughly before use

MGP Plus is an excellent choice for mushroom growers seeking higher yields, stronger mycelium, and biological support against contamination.
