Wild Harvest

CNG Mushroom certification covers cultivated mushrooms, not wild-crafted mushrooms. However, we include this section on the application for two reasons: #1 It is important to us that those who participate in our programs are mindful of the sustainability of the non-certified portions of their operations. #2 We want to give our members the opportunity to be transparent about their wild-crafting practices, and to minimize confusion about which mushrooms are certified.
Are any of the mushrooms you sell wild harvested (or "wildcrafted")? Yes/No *
What types of wild mushrooms do you harvest and sell? *
Chanterelles, Morels, Maitake, Honeys,
Please describe what measures you take to ensure that you do not over harvest these mushrooms, and that there will continue to be wild mushrooms of that variety in the locations where you found them. *
I make sure to leave more than I take, I also host forays where we disperse the wild mushrooms we find back into the forest.
Since CNG doesn't offer certification for wildcrafted mushrooms, you must agree not to market any wildcrafted mushrooms (or products made from them) as Certified Naturally Grown. Please indicate you agree to this requirement by typing your initials here. *


What water contamination experts have you consulted to identify which contaminants are typically found in area water, and determine the tests that should be conducted? Relevant experts may include local or state health department officials, Natural Resource Conservation Service agents, state environmental protection or pollution control agencies, local well drilling and water testing companies. (If you haven't yet done this, please indicate who you will approach, and by when you expect to have completed this program requirement.) *
Chemical Solutions Limited 971 N. 7th Street Harrisburg, PA 17102 717-697-7536
Have you tested your water at the point of use for heavy metals or other contaminants that were identified by local water quality experts? When? What were the results? (If you haven't yet done this, please indicate by when you expect to have completed this program requirement.) *
Test will be completed February 2019
Do you use well water to mist or irrigate fruiting bodies? *
Do you use surface water to soak logs or to irrigate non-fruiting substrate? Surface water includes water from ponds, streams, and reservoirs. *
Do you ever use surface water to mist or irrigate fruiting bodies? *


Do you purchase spawn or produce your own or some of each? (If purchased, please list the supplier.) *
Some of each. Most spawn comes from Mycopolitan in Philadelphia
CNG mushroom standards prohibit for spawn production the use of adhesives, byproducts of GMO crops, or other materials prohibited for use as substrate. Are you confident none of these materials were used as a growing media for the spawn? *

Pest & Disease Management

Describe your primary insect pest challenges AND methods of prevention and control. (Do not answer "none". You MUST indicate actual pest challenges or LIKELY challenges, and you must ALSO indicate how you manage or how you would manage them. If you indicate a product, also specify how often it's used.) *
Slugs, and Flies. I use fly paper in the outdoor tents and copper wire around the tent for slugs, also occasionally set beer traps.
Describe your primary disease challenges AND methods of prevention and control. If you indicate a product, also specify how often it's used. *
Bacterial or mold contamination is controlled by sterilization and pasteurization. If anything becomes contaminated in the fruiting space it is removed and composted in another part of the operation.

Site Location and Buffers

Is your operation either partially or entirely INdoors? *
Please describe neighboring land uses to the north, south, east and west of your INdoor operation. *
All residential homes
Do these uses pose a risk of drift or contamination? If so, please describe. *
How does your ventilation and air filtration system prevent possible contamination? *
Only cordyceps are grown indoors, they don’t require ventilation
If you share space with other producers, please indicate whether they use synthetic chemicals, and if so, how do you protect your production area from potential contamination? *
Is your operation either partially or entirely OUTdoors? *
Please describe neighboring land uses to the north, south, east and west of your OUTdoor operation. *
All residential
Do these uses pose a risk of drift or contamination? *
What is the distance between your outdoor production area and the nearest sources of possible contamination? *
What other factors mediate the risk of contamination? (Prevailing wind patterns, windbreaks, method of spray, etc.) *
Has your outdoor production area been treated with prohibited substances within the past 36 months? If so, by what was it treated, and when? *

Sustainability Initiatives

What measures have you taken to conserve energy, improve energy efficiency, and/or use energy from renewable sources? (This could include system design, siting, insulation, lighting choices, and more.)
All electricity is used for stelization, heating and cooling. We are working on a gasification machine to replace propane this year
Please use this space to highlight any other measures you take to reduce the environmental impact of your operation or to make it more sustainable in other ways.

Inspections & Networks

A core requirement of CNG certification is the on-site peer-review. Getting this completed is facilitated if you're a part of a network of mushroom producers who might serve as your inspector.
Are you a part of a network (informal or formal) of mushroom producers in your geographic area? *


I will not label, or in any way lead consumers to believe that a farm product not raised in accord with CNG standards is Certified Naturally Grown *
I understand that I have to complete at least one Inspection of another CNG mushroom producer in my area each year, if there is one within a one hour drive. *
I understand that the inspection I conduct will NOT be of the same producer that inspected me. *
I have reviewed the Certified Naturally Grown mushroom certification standards, I understand them, and I will abide by them. If I have any questions I may contact CNG for clarification. *
You may use this space to tell us anything else you think we should know about your operation.
