Hi, I have a flood tray with a sheet of ABS suspending 5" netcups and i have 1/2gph drippers i want to try, using root riot plugs and hydroton only. could i use a regular 15min/24hour timer or do i have to buy drip timers? how long/many times per day should i run the drippers? and where should i place the dripper? place it to when its just barely hitting the plug?(which will still soak it) should i put 2 drippers on each pot? thanks for any help
