it's so much easier and cleaner and no more little flies! I seen someone in here talking about it,      (think it was you Sub) so I looked on youtube to see what was needed and made the switch. now that I have the right nutrients it's so easy, I don't even need to PH using advanced nutrients, I still check it. can't believe how thick the stem gets. OK so here's my thoughts on it.                       DWC it's a good good thing!!!
