Fem seeds lack things that males bring to the table. Vigor, strength, height are the most obvious. I'm sure there are also many more too. I've grown the same way for 14 yrs. 5x a year, I plant 12 seeds. 11 regs and 1 fem. The fem plant is always the smallest and weakest of the 12. Visually, this is incredibly obvious. I am also concerned about what may be lacking that we can not see. Terps, cannabanoids, other medicinal components, immune system? Idk, but no reason to assume that these are complete plants. Moms should be vigorous, healthy, produce, in it for the long haul. Better chance of this with reg seeds. Complete Moms from regs. I've finished some great fem seeds over the years. Good yields, good bud. Really nice stuff. But when seen next to reg seeds, consistently, easy to see that they are inferior.
