What toxicity issues exist with hydroponics? I know nothing about growing plants.
- emillon 14y agoWhen you grow plants with no soil (only neutral substrate such as clay or gravel), it is necessary to provide extra nutrients (esp. nitrates) that are hard to dispose properly. In the case of vegetables or edible plants, it is also necessary to "rinse" the system by running only water through eat before it's ready for consumption.
