Flush Question

Im not ready to flush yet, however I have herd so many different ways to do it. Including a dark 24 hour cycle...blah blah blah, whats the deal???? how do I do it properley? and for how long?...its hydro by the way...flood and drain

Hydro baby!!Flood and drain is the way.Love it! I flushed mine for 14 days with normal 12/12 lighting and plain water w/ph at 5.8 and you could hardly tell you were blowing smoke out.Smooth as a baby's ass baby.No chemical taste what so ever.Everybody commented on how smooth it was.Ya it sucks waiting but give it a try once.Good luck..
