fasten the pvc piping down to the nutrient container?
 

i am making the 11 plant hydroponic system and i was wondering how should i fasten the pvc piping down to the nutrient container? thanx for your responoses!!

why? You growing in a hurricane. You can use bungee cords to hold the sucker down or if you need a more permanent way use elastic ties. Just ask the cops for some the next time you are busted. They use them for hand cuffs.
