Buttered Grapes Indoor Led Grow

By week 4 these have each been topped and are ready to be transplanted into larger pots. I germinated 10 seeds and kept the 6 fastest growing, strongest looking seedlings knowing full well that since these are regular seeds, some of those slower growing seedlings may have been females. That’s okay for my purposes. I only need one or two good females so I wanna pick the plants that seem strongest right out of the gate. With 6 remaining plants I know statistically that at least 2 or 3 will be females.
