Plagron expanded clay pebbles are obtained from volcanic rocks, now available in Alchimia. With them we can set up our soil (mixing between 10% and 35%) and give it a more porous texture, improving its drainage capacity.
Their capacity to provide the right ratio of water and air to the substrate - free from pathogens - ensure the proliferation of roots and improve plant's growth.
They can also be used as an inert substrate for hydroponic systems like Aquafarm .
