hi im a beginer aswel but i know sum stuff. i think you will need i bubler in the tank to stop the nutrients settling at the bottom and to keep the mix mixing. you also need to keep the water warm to stop the plants from going into shock you can buy heaters online for cheap for this. you should clean out the tank and make a new solution every 1 or 2 weeks to stop algea from forming.I decided for my first grow to go hydro , but i'm worried what goes into the water. I know i have to maintain a certain pH level, but other than that I have no clue. Can someone help me out
