What ever kind of hydroponics you use the first thing to purchase is a monitor being a bluelab guardian or neptunes apex. A water level gage on your reservoir. It is very critical to monitor your system PPM, PH, Temperature, reservoir water level these 4 things will make or break your grow. Being able to monitor everything at a glance is key. When your PPMs go up and your water level goes down your nutrients are to strong (lockout) When your PPMs go down with your water level increase your nutrients. Perfect is PPMs will be stable and not change when water level drops. If you purchase the apex great controller sky is the limit on what you can do from your cell phone. Also consider a dissolved oxygen (DO) meter or oxygen reduction probe (ORP) for the apex. Using one of these will tell you what the oxygen levels are in your nutrient solution. Good luck .......
