Dr. Myc MGP Pure Microbes

Get better harvest yields and faster colonization times with the mushroom growth promoting bacteria in MGP Pure.

MGP stands for Mushroom Growth Promotion - and DRmyc's PureMGP is the world's first blend of micro-organisms exclusively targeted towards that purpose. This formula encourages drastic yield enhancement and is suitable for use by amateur mycologists, hobbyist mushroom growers, and mushroom farmers alike. With DRmyc's PureMGP blend, you can reliably expect an increase of between 30-70% in yields, while decreasing the time to fruit substantially.

Each pack of MGP products contains microbes selected specifically for their growth promoting properties. MGP Pure has a number of benefits when applied to your grain and substrate mixes, including decreased time to pinset, increased fruit size, and increased net harvest weight.

The MGP Line is cost effective and easy to use, with each 10g pack making enough ready-to-use spray to treat approximately 20 monotubs or 40 grow bags.

This blend utilizes microorganisms that have the following effects upon your substrate, to promote healthy mycelium and bountiful fruiting bodies:

• Solubize phosphate
• Fix nitrogen
• Solubize zinc
• Solubize potash
• Release VOC's that promote vigorous fruiting
• Decrease time to fruiting, sometimes as drastically as 50% versus untreated
• Increase yields substantially over the substrate lifecycle
• Increase the viability of secondary flushes & reduce contamination
• Strong passive resistance to bacterial contamination

If you have issues with Trichoderma harzianum, please check out either our TrichEVICT 80/20 MGP blend, or purchase a pure contaminant reducer alongside your MGP to mix together as needed for the severity of your contamination issue.

Usage

• Add 2 grams of MGP Pure or MGP Plus per 1L of non-chlorinated water (RO or Distilled is best) and add to a sprayer bottle.
• Mist colonized grain spawn directly when mixing spawn and bulk substrate material, and then mix it in. Avoid spraying substrate directly where possible, and do not overapply – usage rate is 1 “spray” per pound of substrate used.
• Apply once weekly if additional treatments are needed after pinset and fruiting have begun.
• Store extra mix in the refrigerator and uUse the contents of the bottle within 6 months for best results.
• ALTERNATIVE DRY USE: To use dry, add 1G per 2.5 Gallons of water to the grain soak and mix with grain/water.

When doing multiple flushes, MGP Pure can be used as a dunk additive for your colonized cakes between flushes, at a rate of .25 grams per block being dunked.
