Cropping Cycle:
One crop indoors. Spawn can be placed outdoors for creating natural patches.

to encourage Black Morel fruitbody formation. A fine layer (1 inch) of moistened vermiculite aids
aeration. Since the physical separation of the the nutritional seed layer from the nutritionally poor
peat moss is not necessary, this technique is uniquely different than those which have been patented
by Ower et alia. The pH optima for fruiting falls between 6. 5-8. 0.

This is a proposed initiation strategy based on my observations of natural fruitings of the Morel and laboratory research

with Morchella angusticeps, the Black Morel. This strategy will be amended and improved over time.
