just bought my first hydro kit wilma 16, which drippers are which? flood and drip theres blue and black ones not shore which is which. and anyway wouldnt it be best to leave the drippers off to get more nutes to theroutes?

i also have a wilma and only had it a couple days but im pretty sure the black ones are the arrows and suitable for coco,soil etc the flood ones are for clay pebbles, rockwall cube and PU foam. Hopefully someone will shine some more light on the subject just incase

black = drip
blue = flood(continuous flow)

I got a wilma 3yrs ago with blue flood arrows and black drippers but i also bought a wilma last year and both the flood and drippers are black .Is it possible they change?. .A flood arrow has the water flow through it onto an edge that causes it to sort of fan out..Hope this helps and sorry for crappy arrow description and possible confusion
Plotty Pants..

better description than mine lads im worried about nutes to add tho
