Hopefully can sex them in veg, not always possible though.
Like Reza said, you can take clones, put the donor plants in flower and chuck any corresponding clones that were taken from the males. Best option if you have a veg and flower room. From there you can also select the keeper/s based on the flowered donor, how they took to clone, no hermies etc. Or do the reverse if you want to keep the “seed” Mum.
Another option is to put all into flower, chuck the males if not wanted and monster crop the females at around week 3.
Or simply do it the way you did, which is what I do during a last run of a strain as I’m limited to a veg/ clone tent within my main room. Switch, sex, back to veg. I try to time it so I’ve got a batch of female clones ready to go out once the clean down and reset is finished, with enough to go back in as donors. From there select pheno/s from that run.
