This issue we cast the Hydromag eye over the current types of potting compost you will find gracing the shelves of all good grow stores, and even some of the not so good ones.
Soil? Why the bloody hell is a hydroponics magazine looking at soil? That is what we’re looking at here, isn’t it? I mean, everyone calls it that don’t they? How many times have you heard “Ten bags of that there soil me ol’ china, that’ll do me”? Must be called that then, eh? I’m sure you can see where this is going. Strictly speaking, none of this is soil. Not unless your local growshop is quickly nipping out the back door and scooping some dirt out of the ground and into a bag to sell you, which wouldn’t surprise me. The word ‘Soil’ directly means the upper layer of earth in which plants grow made from a mixture of organic matter and rock type particles. Maybe loads of broken glass, too if you are really lucky like on me on my allotment.
