Dr. Myc™ MGP Plus Microbes

Prevent Trichoderma Contamination in Monotubs

Each pack of Dr. Myc™ MGP Plus contains microbes selected specifically for their growth-promoting properties. MGP Plus contains a similar makeup of bacteria to MGP Pure, with added microbes designed to prevent contamination from harmful pathogens like Trichoderma.

MGP Plus has a number of benefits when applied to your colonized grain, including decreased time to pinset by 5 - 15 days, increased fruit size, increased net harvest weight, and reduced risk of Trichoderma contamination.

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.

When using MGP PLUS and MGP PURE as a system, use PLUS for contamination prevention and faster pinset, then supplement with PURE during fruiting and post-harvest. 

MGP PLUS INSTRUCTIONS

1. 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. . 
2. 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” (~1ml)  per pound of substrate used. 
3. Apply once weekly if additional treatments are needed after pinset and fruiting have begun. 
4. Store extra mix in the refrigerator and use the contents of the bottle within 6 months for best results.

ALTERNATIVE DRY USE:

• To use dry, add 1G per 10 Liters (2.5 Gallons) of water to the grain soak and mix with grain/water.

NOTE: MGP Plus can also be used as a part of the grain soak when preparing grains, creating metabolites hardy enough to withstand sterilization, resulting in faster colonization of your grain and lower contamination rates.

• Add to grain soak at a rate of 1G per 2.5 Gallons of water and mix with grain/water.
