Definitely a premium soil, but you get what you pay for. I like the approach this soil takes. It's a inert clay/volcanic base that comes with nutrient capsules you place yourself. If you're planning long term and can afford it, their power sand is really great as a base substrate to have under this soil. If you're on a budget though, some lava rock or rubble can account for a lot of the aeration benefit you get with the power sand. Happy scaping everyone!
