thank u for the help another ? is how do i know when it's time to move the seedlings to the aero i have 5 lil plants growing i planted on the 14th and there about an inch now. the stems coming up is red on one side and a nice green on the other running up the stem the leafs are tough looking thick but when i touch the plant it seems loose in the rocwhol maybe the roots are'nt deep enough? and iv'e noticed 1 seed has not sprouted at all so i opened up the hole to look in it and there was white fuzz stuff on it and it was not sprouting at all.everything else seems fine other thani don't know what i can do about the water down in the tub im starting to feel a thin layer of slick stuff im guess it's alge and all the tubs i painted black and the tops black then white so im guess the light is getting through the clay balls around the edges so maybe sum plastic over top of them?
