When it comes to the age-old debate over whether it’s better to grow cannabis in soil, or to grow the plant hydroponically, what we’re really talking about in 2017 is outdoor versus indoor growing. Why, you might ask? Simply put, it’s because no one actually grows indoors using real topsoil anymore, as our indoor “soils” are really soilless mixes that are coco-, peat- or sphagnum-based. And, technically speaking, these soilless mixes are, by definition, hydroponic mediums; today, the only real earth soil used is in outdoor gardens. So let’s examine the pros and cons associated with both growing outdoors in soil and growing indoors in hydroponic mediums.
