ok so i got 3 sprouts under 6 27w cfl daylight 6500s i know u use them for vegging....i got 4 23w cfl and 1 68w cfl 2700 soft whites for flowering....can i just put both sets of light on the sprouts during veg to make the preflowers come out earlier to sex my plant..or my big question is will it work
they should show sex around week 3-4 normally...if not sure on what your looking for, you may need to flower them(switch lights to 12/12) adding different spectrum of light will not induce flowering.
should be able to see with your eyes...some take longer than others though, Ive had a few strains go longer but normally I can tell by week 4 at the latest.
