I'm new to DIY farming and have invested in a vertical farming unit. I love the efficiency and effectiveness of these systems in providing nutrients, oxygen and water to the roots of plants in a small footprint.
The unit came with nutrients labelled A and B, which you would add ml of each to your water reservoir to make the water nutrient rich to grow tasty vegetables. This got me wondering... is it possible to extract my own plant nutrients from tons soil I have laying around?
is it possible and how would one achieve this?
