Sweet as. I recently started using one of these IWS DWC systems.

I had almost completely lost my first harvest due to some infection in the system. The second harvest looked much better however the buds didn't really fill out, but the plants were stunned early on from a slight infection again, however they took off once I dosed the hell out of them with Dutch Master Zone. The third cycle is currently growing and I'm having no bacterial type infection issues at all. I am however having some nutrient issues now, but I'm feeling like i'm making progress. The trick for me is to run pure hydroponic / synthetic nutrients with absolutely zero bio / natural ingredients at all, along with Dutch Master Zone and it keeps the system really really clean.
I started to do a grow journel of my first RDWC grow but gave up because I have having so much heart breaking trouble with basically losing crops. But if I get this one out of the way without any disasters I'll start documenting and photographing them again on here to show peeps how I did it. Because as far as I'm aware there's really not much (or nothing) in the way of RDWC grows on here.
