So my friend was telling me last night about a certain type of mycelium, mycelium being the "leech" root system from which mushrooms grow. He was saying how they took this type of mycelium and it worked symbiotically with a pot plant, enhancing root growth and it also pulled more nutrients from the soil and in turn, fed the plant better. Now here's the question, is this bunk? or is this something someone on here knows and / or uses? Thanks fellow organic growers!
