help yourself to the bubbler, I copied it from Opie Yutts :thumbsup: ... I don't feed anything to newborns, and use chlorinated tapwater to help prevent 'pythium wilt', etc. the first several days (I have no idea if the chlorine helps, but it seems logical) ... the cotyldons contain everything the seedling needs for its first two weeks ... two weeks in, I will add a 'weak' dose of Fox Farm 'Grow Big Hydroponic' version, etc ... as an aside: I do NOT use 'Superthrive' for anything, except some occasional cloning (over-rated, over-advertised, swill) :wtf: ... :jointsmile:
