I want to set up a hydroponics system but don't want to buy commercial nutrient or medium.
Can i just flood the soil the plant is growing in for a temporary portion of the day?
I don't have a problem with the pump, just buying the nutrient / medium.
Can i just use soil and wet it down really well once a day and then drain it (out the bottom)? Would floating soil in the water being circulated through the system work? I could empty water / put more soil in on a regular basis.
