<p>Support capable of enhancing mushroom spawn growth and carpophore development, and containing an inert, porous granular substrate, such as expanded perlite, and a nutrient phase conveying, in particular, those chemical elements essential for spawn growth and carpophore development. The inert porous substate is in a virtually anhydrous state, has a relative density less than approximately 0.2, a particle size of 2-5 mm, and a volume void ratio of 20-40%. The invention also provides a method of obtaining said substrate.</p> |
