are there products with fewer than 12 emitters. and if you are only using 11 of the outlets can the remaining one be plugged?
A shopper on Sep 8, 2012
BEST ANSWER: There are smaller emitters and you can plug the ones you don't use but large plants take 3-4 hoses so you might need more emitters than you think and having more than you need leaves you room to expand.
Top- 300-DIG 12 Outlet (3.3 GPH per zone)
is it 3.3 GPH total for all 12 outlet ?
or for each outlet?
A shopper on Sep 6, 2011
BEST ANSWER: I have no idea how this 3.3 gph factor comes in to play. I hooked mine up to a 265gph pump I had purchased from Home Depot and it most definitely did not restrict it to 3.3gph.
