You lost me a bit m8, bear with me, it sounds like you got the rezz underneath with airstones in it and from this the mix feeds the dripper rings ? if so it just sounds like a reciculating wilma mukka with a few airstones in the rezz and better drip rings, so it`s a modded wilma to me with new airstones and dripper rings, i just don`t wan`t badbillybob thinking it`s RDWC if it isn`t that is all mukka or am i miles off in thinking that.
Well now its got the huge root balls in the res its more hybrid RDWC now with the added benefit of being top fed.
The are drinking a lot more now the roots are in the res.
To me is working just like a load of buckets as you do in RDWC except mines in one giant bucket with the (4000ltr/hr) pump in the middle recirculating the nuits around.
