^^good point bozo, if things turn ugly they do it with the speed of light in any hydro system.
But, on the other hand have several members here also grown their first green in some kind of hydro system as ClosetDWC or one of the starting members named Roseman that also never used anything besides tonnes of CFLs and his rubbermaid DWC units - so t is doable but you have to on the watch all the time as you have to do all the read before you start, so better read it twice
