No, you guys dont want your medium soaked in water, u want it some what damp, the point to having your water level below the net pot is so your medium has a constant dampness and not soaked, id your using rock wool or rapid rooters you want you medium to be somewhat damp. if the water level is above the net pots your medium will become to wet, when your roots grow down they go into the water, its not the point of the roots being soaked in water as much as it is your medium, if your medium is too wet your can get root rot and slow growth along with other problems such as over watering. you need air to get to your roots.
