The younger girls won't doing to well in my dwc because I was using pipe water and I had no ppm tester ... Was a constant battle to keep ppm down , anyway I just decided to plant them in pots and try to root clones from bub and Cairo for my dwc instead ! So I got my 4 in the soil pots and once my clones root well ill put them in the dwc system... The seedlings are under cfls and during the day I put them on the side of the flowering ones to get a little of the hps light but I don't put it directly under the hps ! But I started buying the 5 gallon bottles of r/o water which I will b using in my dwc once I get rooted clones ! I was also thinking about keeping my 2 seedlings as mothers so I don't mind leaving them in soil for now .... But thanks for asking Dutch ,...
