    Improved Yields & Faster Harvests From Your Monotubs

    Each pack of MGP products contains microbes selected specifically for their growth promoting properties. MGP Pure contains a blend of microbes designed to promote fruiting and improve harvest yields.

    MGP Pure provides a number of benefits when sprayed as a mist onto colonized grain, including decreased time to pinset, increased fruit size, and increased net harvest weight. MGP Pure can also be used to support second flush harvest weights, maximizing the use of available nutrients in the substrate in a shorter time.

    A System for Mushroom Growing Success

    The MGP Pure and MGP Plus products are designed to be used as a system - use MGP PLUS to ensure a strong, contamination free monotub at the time of colonization, and supplement between or during fruiting phases with MGP Pure to maximize harvest yields.  Best of all, the MGP Line is cost effective for growers at any scale, with each 10g pack making enough ready-to-use spray to treat approximately 20 monotubs or 40 grow bags.

    Usage

    • Add 2 grams of MGP Pure or MGP Plus per 1 liter 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. Avoid spraying substrate directly where possible, and do not overapply - usage rate is 1 “spray” per pound of substrate used. 
    • Apply once weekly to colonized substrate if additional treatments are needed after pinset and fruiting has 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.

    NOTE:  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.
