    THE LIFE CYCLE OF THE MARIJUANA PLANT



    Germination: [​IMG]


    This is the initial stage of growth and occurs when your
    seed’s embryo cracks open and the seedling produces a root. This root
    fixes itself into the soil and pushes the newborn seeding up and over
    the soil surface. Following surface contact two embryonic leaves open
    outwards to receive sunlight, pushing the empty seed shell away from
    the seedling. It takes anywhere between 12 hours to 3 weeks for seeds
    to germinate. Once the plant has reached this stage it goes into the
    seedling stage.


    Seedling Stage:[​IMG]


    After the first pair of embryonic leaves are receiving light
    (Figure 2.12), the plant will begin to produce another small set of new
    leaves. These leaves are different from the last and may have some
    Marijuana characteristics such as the three-rounded finger shaped
    points. As the seedling grows, more of these leaves are formed and
    bush upwards along with a stem. Some stems are very weak at this
    stage and need the support of a small thin wooden stake tied to the
    seedling with some fine thread. The seedling stage can last between 1
    and 3 weeks. At the end of the seedling stage your plant will have
    maybe 4 -8 new leaves. Some of the old bottom leaves may drop off.


    Vegetative Growth:[​IMG]


    The plant now begins to grow at the rate which its leaves can
    produce energy. At this stage the plant needs all the light and food it
    can get. It will continue to grow upwards producing new leaves as it
    moves along . It will also produce a thicker stem with
    thicker branches and with more fingers on the leaves. It will eventually start to show its sex. When it does this it is time for the plant’s pre-
    flowering stage. It can take anywhere between 1 and 5 months for the
    plant to hit this next stage.


    Pre-flowering:[​IMG]


    At this stage the plant slows down in developing its height
    and starts to produce more branches and nodes. The plant fills out in
    the pre-flowering stage. During this phase of the plant cycle your plant
    will start to show a calyx which appears where the branches meet the
    stem (nodes). Pre-flowering can take anywhere between 1 day to 2
    weeks. (See last page of this book for pre-flowering/calyx illustration)


    Flowering: [​IMG]


    During this stage the plant continues to fill out. The plant will show its
    sex clearly. The male plant produces little balls that are clustered
    together like grapes. The female plant produces little white/cream
    pistils that look like hairs coming out of a pod. Each of the plants will continue to fill out more and their flowers will continue to grow. It can take anywhere between 4 to 16 weeks for the plant to fully develop its flowers. During this time the male’s pollen sacks would
    have burst spreading pollen to the female flowers.


    Seed:[​IMG]


    The female plant will produce seeds at this point if she has received
    viable pollen from a male plant. The seeds grow within the female bud
    and can take anywhere between 2 weeks to 16 weeks, to grow to full
    maturity. The female pistils may change color before finally bursting
    the seedpods, sending them to the soil below. (Breeders like to collect
    their seeds before the seedpods burst.)


    These are the six stages of the life cycle of a cannabis plant. It
    is important to know that if the males are separated from the females
    and killed off then the females will not become pollinated. Let us go
    back a step and describe what happens here.

    Hello, thanks for the great info. I am new to this and have started my first grow and I have a few questions if you have the time to get back with me that would be great. Here is what I would like to know. I am at the start of my 3rd week in from planting 2 seeds, 1 Afghanistan diesel and 1 blueberry kush. Both have grown to only about 4 inches tall with the diesel being a tad shorter. Is this normal? I have watered approx. every 3 days and keep a temp at around 70-75 degrees and light 24 hours a day. It has its first leaf set and looks like the first picture you posted in your life cycle thread. Should I change the light schedule now or should it be taller than 4 inches? They both look healthy and I really want them to work out but I'm concerned they aren't growing as fast as they should be or maybe I have stunted the growth in some way.
    That's all the questions I have for now. I hope you can find the time to get back with me. Thanks in advance.

    I have a confusion ! the seed bank says flowering time : 60-70 days. does this mean total growing of the strain from germination is 60-70 which includes all stages of growing, or does it mean 60-70 days from the first day of flowering ?

    Great post should put this on newbie central,think new growers could use this for reference,I doing a blue dream next got two chickens of it under a t5,the front runner will be put under led,next time.

    I was going to run,the blue dream in my main room,but decided on Pineapple Express,got a real addiction to that strain now.what the smell like dude is it pungent .

    Finish times are usually from the first day of flowering, considering you veg the plant long enough that it is sexually mature. Sometimes these flowering times are a little off.

    I believe that in auto flowering strains the total time from germination to finish is listed and not days of flower.
