For newcomers to indoor gardening and hydroponics the voluminous array of products on offer can be something of a headache: from choosing a system, lighting, ventilation, what to grow, where to grow, to considering nutrient solutions, and so on and so on. And then of course there’s growth media. There seems to be no end of options and permutations. It’s enough to make one throw one’s hands in the air and give up before even starting. But don’t despair - this is where you must let the paternal arm of HydroMag wrap around your shoulders.
Firstly, some of you just starting out might be wondering what “Growth Media” actually is (fortunately nothing to do with medical journals dedicated to discussing tumours). It’s essentially soil substitute (or substrate as it’s also known). As your plants’ nutrition will be derived from solution, not soil, the growth media we’re talking about is, in effect, just there to hold the plants in place (think Neo in The Matrix, after taking the red pill, waking up to find himself suspended in a strange liquid – or growth medium!).
