    Takes about 6-10 weeks into veg growth, 1-3 weeks into flowering, and could be anywhere from 2-24 inches in height before it shows sex.

    you vegg 24/0 18/6 every day untill you start to flower, then you have to have 12 houre lite and 12/hours compleat darkness, unless growing outside,but its not the rite time of year to be growing outside yet.
    i vegg for 4 to 6 weeks and keep the lite on 24/0 all the time, this makes the plant grow.
    then when you switch to 12/12 thats when you start telling the plant to flower.
    and after you have been doing 12/12 for 2 to 3 weeks, then you will able to tell sex,
    you must go to 12/12 b4 you start growing buds, or to tell sex,.
    it isnt how big before you can tell the sex.
    btw. you must flower the plants for 6 to 10 weeks depending on strain.
    havent you even read up on the basics.lol
    faq read up.maybe the basics,maybe before you stert to grow.it help to know what your doing.
    any pics of your plants.

    If you really look close you can determine sex once you switch to 12/12 in as little as three days. Look for the real thin hairs between nodes.

    if you dont want trees, if you want to use less electric, less heat, if you got a good light just go 12-12 from seed....sex for males shows around 2 ish weeks and fems by 3 weeks............with a 400 hps you can pull 1 1/2 + dry oz per plant.......with a 600 hps im pulling up to 7+ oz dry per plant.......12-12 from seed rocks
