Hi I've recently started a hydroponic grow and I've been hand feeding until now. I just connected a drip irrigation system but for the life of me I don't understand how it keeps dripping. I have a chemical res and a pump inside thats connected to 4mm tubing that goes to my 4 babies. They are about 20cm tall right now. I connected everything up and the pump runs off a timer and the timer turned off after its allocated 8 minute fast drip. I'm feeding them 800ml twice a day. Anyhow after the pump turned off it kept dripping so I restricted the valves to slow it down and I out this to water still being in the lines. So I waited and waited but it never stopped. I can only put this to the pipe and water started pressure and the more water coming out at the plants end started a vacuum and now its feeding itself. I understand people will say a 24 hr drip is better and will work better but I want to understand why this is happening. Can someone please explain
