warmer than room temp. water
 

hello, I'm trying to start up an active hydro system, and have a few questions for you. we have everything set up but i needed to know if i can continuously run water through the medium.Or do i need to put the pump on a set cycle. If i can run a continuous flow of water through the pipes is there a certain level the water should be at. I have an air stone running in the system. Do I need warmer than room temp. water? can the roots be completely submerged under the water in the pipe? thank you tommy two toke

You can if you put an air stone in your tank to add a lot of oxygen but it's not recommended because your roots do need that ebb and flow action for healthy growth. NFT systems are continuous running and work well because the water is flowing and doesn't sit in almost stagnate water.
Room temperature is right for your water. Ron
