You need to rinse it twice a day with cool not cold water, just plain water. Sprouts do not need fertilizer. I put mine in the sink and fill the container then let it drain through several small holes I drilled in one end of the container. If I am running late I sometimes just mist them with a spray bottle but only once a day. They need the film rinsed off that is created with the sprouting process or you will get fungus or mold. I will add a few Picts later tonight. I've had so many questions I am making a PowerPoint and will post it on my FB page tonight or tomorrow. fintucky farms future homestead or Tri-city hydroponic gardeners.
