Does anyone here use organic "super" soil to grow cannabis? This type of soil does not need any added nutrients. Just water your plants with a decent water source and let the soil do the work of adjusting pH and providing nutrients slowly over the course of a plant's life.
One way to make super soil is to first amend a good potting mix with extra ingredients like earthworm castings, blood meal, bone meal, guano, "good" fungus, etc (top pic). After mixing it together (middle pic) the soil is composted for a month or two (bottom pic) until it's nice and cooked. This creates a thriving colony of microorganisms and starts releasing some of the nutrients from the amendments into a form that can be easily absorbed by plant roots.
However, many of us don't have the time, space, or inclination to compost soil at home. Or maybe you only need a few gallons of soil at a time, so making a hundred pounds of soil in a compost pile isn't practical. That's why it makes sense for some growers buy pre-made super soil. One popular option is Kind Soil, which is available on Amazon for $35 per 5lb bag (good for a single 5 gallon pot). It is pretty expensive but seems to work great for cannabis when you follow Kind's instructions.
If you use composted soil to grow cannabis, where do you get your soil? Do you have any tips for new growers looking to get into organic growing for the first time? What about #notillgardening?
