female or male

I have just got hold of some thai super skunk seeds but they are not femanised so any advice will be greatly accepeted will i have to put plants into flower to find out sex.I have had male plants before but was wondering if there is any way you can tell without budding what i was gonna do is take 2 clones off each of the plants and any that look male cut down and get rid before pollen sacks open and bin clones off that plant.I have 3 that are about 6/7ince looking realy good and i have 10 more in propagation room these are about 3cm tall with seed leaves just started showing ones in prop room are about 6 days old.want to try any sexing advice on the 3 older plants they need to grow more b4 i take any clones though,That green bloke on you tube takes two clones and buds plant realy early to find out sex but if it is female he bins the plant because its to small i'm tight and hate to think i would be chucking a female away so if there is a way of telling without budding would be a great help how can a herb be a crime peace

U can tell the sex without forced flowering but it usually takes 7wks of veggin first. Don't cut down any plant just because u think it may be a male, make sure first, u've had males before so u'll know which ones to pull. U'd be kickin urself in the nuts if u threw out a female. So, if u just keep em veggin long enough, they will show sex but keep in mind that some plants will take more, or even less than 7wks. to show. Also, idk if space is of any concern to u as i don't know what ur workin with, but they will double in size, and sometimes even triple, during flowering so keep that in mind as well. 7wks for me is a long time to veg as i only have roughly 3 verticle feet to work with so i just flip the switch when theyre a foot tall.
