I know anything over 75 isn't considered good in Hydro and 68 degrees water temp is perfect. However Its winter and my rez water is getting below 65 degrees. What temp would you say is harmful to the plants or isn't that great?? Running below 62 degrees in the rez is that too low??
Also is dutch master root zone conditioner good for LOW temps?? I know its good for high rez temps
