Plagron Promix is a mix of the very best, most carefully selected types of peat.The addition of various types of fibre results in a lightness and oxygen level found only in Plagron quality substrates. No nutrients have been added to Promix, only Plagron worm castings. The worm castings stimulate the growth of soil organisms and activate the organic fertilisers which have to be added at the first day of use.
