bingo GIMP works!
my BG next to my NYCD both went on flo at the same time? one in coco block the other in rock wool.
I think the coco works better in my system
I use a flood n drain system (IWS system) but im tryin to keep my tent in flo, but the only prob is new plants get the same watering as plants at the end of flo, and i dont want to under water them at the finish stage, so more experements to be done!
coco def drains better than wool!
