Abstract: A system for applying mushroom growing materials includes a hopper for the materials. A blower unit creates an air stream which acts as a carrier for blowing the material fed by the hopper through a transport hose wrapped partially around a reel. The hose communicates with and feeds the material to an applicating head which is mounted on a mushroom bed. The material is conveyed through the applicating head by being spread in a transverse direction by a distributor. The material is then fed to an applicating member which is preferably a conveyor belt. The conveyor belt deposits the material onto the mushroom bed.

Abstract: A process and device used to produce CO2 in an indoor environment is described. The device contains a container that contains a mixture of substrate and fungi. The container has at least one opening to permit the CO2 to enter the plant growth environment and a pump connected to the container to pump out the CO2 through said opening into the plant growth environment. The invention further relates to a kit that contains a container, substrate, fungi and a pump.
