Help with sex...

I get clones from the shop but want to order some seeds online, how can i tell if my plant is male or female and how long before you can tell this..

you have to veg and then flower to find out what they are going to be.

you could just buy feminized seeds think i spelled that wrong

feminized seeds make it so much easier. And we have a spell check on here. I think you spelled it right.

A more complicated way, but always works as well as the others suggested, you plant seed, you let it veg till it's a lil over a foot tall, take a clone of it, and put the clone to flower immediatly. Then you'll know. Get rid of the clone onced sexed. It'll be useless for anything else.

I do not recommend feminized seeds as they can be stressed seeds. I recommend vegging the seeds and cutting clones off of each of them. Flower the clones after they have rooted, and identify the males by looking for the pollen sacks (balls) and destroying both the male clone and the plant the male clone was cut from. This process will add two or so weeks to the total grow time, however you won't run the risk of contaminating all the plants with pollen (males).

you also could trow it into 12\12 until it shows and then re-veg it little bit stressful but it will work

Thank you all for the helpful info, think ill just top them and toss clone into 12/12... peace!
