You'll get seeds if you want them. You should definitely make a seed backup for yourself IMO- say, take the best male and the best female (yes, it's tempting to save the best female for bud, but good genes are money in the bank) and put them in a breeding box well away from your grow room, or put the MALE in the breeding box and only use him to donate pollen (use a Q-tip and gently dab a bit on the female that you have picked to breed).
Your bigger issue is the autoflower trait. Do not breed with any individual that does not autoflower, in this generation or the next, if you are trying to continue with a true aut strain.
