It’s more than just soil! Alpha-Mix is based on careful selections of black peat and white sphagnum peat extracted from sustainable Baltic sources. It is blended together with worm manure, lime and rich organic nutrients formulated for Growth Technology by a noted European agronomist. The product is designed for optimal plant production in pots and containers – indoors or out. Alpha-Mix is a light and friable medium fortified with specific nutrients for explosive growth. Pure lava sand is added for improved drainage and enhanced aeration. Lava sand is a superb addition – superior to the perlite used in other soil mixes. Unlike perlite it leaves no unsightly residue when old soil is discarded or used as mulch. Alpha-Mix is a sensational development in professional soil formulation. It is significantly drier than other soils on the market. It is designed to offer maximum aeration to the root zone and to resist water logging. This is the characteristic that delivers faster and more vigorous growth and is a product of the careful professional formulation of this product. What makes Alpha-Mix?
