Hydrophonics

So... exactly what is it? It is growing most any kind of plant without soil. Soil is mixed with plant nutrients or mineral salts put there by constant erosion and climactic action.
Fortunately mineral salt nutrients mix well with water so when plants take in water they are also taking in these nutrients.

Take away the soil leaving the mineral salts and you have what is termed 'a hydroponics growing system'.
This is probably as good a time as any to provide a bit of clarification. Throughout this site and this page I will be referring to 'nutrient solution'. This is merely water mixed with a small amount of hydroponics fertilizer that is composed of the required mineral salts.
