male or female?

So I bought some regular seeds. Just wondering if there is anyway to determine sex during the vegative stage or do I have to go through the whole bloom cycle to look for nut sacks. Thanks!

The fastest, most effective way I have used is to veg for one week, then cut a clone off each plant and root it for 2 days. Then throw it into the flower room. Within a week or so, you will be able to tell what sex each plant is.

you should see pre flowers from 5 to 7 weeks in veg.
