i was just wondering what the average length of time it takes before your plants start to show sex? I was thinking of sprouting some bag seeds (several) and just growing out untill i can sex a female and then take clones from the female to start a 2 plant dwc grow, that way i KNOW i have females. Probably will turn the first female into a mother or i will just take a clone from each plant before i put it into harvest to get a continual system. Thanx for any info!
I don't know in terms of weeks, and every grow is going to be different in that regard, but it's well into the flower stage. Your best bet is to start a few seeds. Clone while in veg - keep track of which clones came from which plants, then when the first few that you grew from seeds get into flower and show their sex, kill the males and all the clones that came from males. I don't think that it is possible at all to determine sex before flowering.
There are other options too. I have never personally done this, but a few friends have. They will take their plants, and go 12/12 almost right away until flowering starts and you can determine sex. Then go right back to 24/0 veg period lighting with your ladies. The plant will go back into veg phase, with a slight stall. I am sure it causes some stress, but it is another option you have, and I have seen this work and be successful. My .02 IslandMon
nah, you veg for a while and when preflowering starts you take a clone of each of the plants, put the clones on a 12/12 (the clones are the same age as the parent it is ready to be flowered right away) and see what ones show male and what ones show female
