hi there im watering 25 plants from a rez with 13mm pipe and 4mm pipe going to each pot ,i didnt put any type of dripper on the end of the spaghetti 4mm lines i just staked them and clipped the pipe on ,but when i switch on my pump it only pumps water out to the ones nearest the rez and the others are not getting watered ,do i need to get a bigger pump or do you need dripper emitters on the end of the line to build pressure so the pump will pump futher ...it would of worked great if it had to water evenly ,i would of only had to set the timer for 3 mins a day or so ,would a bigger pump sort me out ...thanks guys peace
