    i usually induce flowering at 12". if you have limited vertical space then flower sooner.

    I start flowering when the plant is mature enough to flower.

    I use the general rule of thumb that a plant will grow 2 to 3 times larger when flowering, so flower when about a third of your grow space is used up. Indicas are generally shorter and bushier and sativas are generally taller and lengthier, adjust with experience. Happy Growing!

    Well if your using an incandesant light its not gonna grow, it will die everytime. You need a cfl or fluorescent light wit a color spectrum of 5000k to 8000k. Go to walmart and buy 1 of their 10 dollar grow lights if u are just gonna grow 1 or 2 plants. That will veggem up to 12 inches nicely.

    bongsmilieI have 2 plants, white widow and green crack, both are clones. We started them growing them with an aerogarden for like 2 weeks, then we started switching them into the daylignt for about 8 hours then under the lights for another ten hours a day. They got up to about 2 feet when we decided to to put in 2 24 inch plant lights on the sides, 1 36 in light in the from near the bottom, and 2 48 inch plant lights directly above them, along with the aerograden mounted on the corner. We just switched to 12/12. They are both 28 inches tall. How much taller should they get during the budding process? The green crack is looking really bushy. We just switched them for 3 gallon pots to 9 gallon pots last week as well.

    2 ft is pretty tall By the time Ur done flowering They more likely to be 3 ft or even taller(No prob with that of course) But this one time I had a pretty tall(about 2.5ft) and skinny plant(OG), about 9 weeks into flowering 1 morning when I went to check them out, I found that OG bent from towards the bottom of the stem. I couldn't save it not even with support. But again it happened only once..

    Bro you can flower right from seed the height of the plant does not matter. Every grower has their own preference, mind if I ask how you failed on your past grows? Might be good to see if we can find out where you were having problems..

    Did you check your Ph regulary?
    If so what did you keep your PH around?
    What soil/growing medium did you use?
    What kind of nutrients and did you follow what the bottle suggested?
    Did ya leech your plants every so often to leech out the dissolved salts?
    Towards the end how did your leaves look (color and what not)?

    Just a few questions maybe we can help out to prevent anymore problems :weed:

    I sure hope you have your plants in at the very least a 2 gallon pot or better yet 3 gallons.

    The best way to figure this is to work backwards. Look at your flowering bulb and figure out how close a plant can come to the bulb without burning. That is the maximum height you can allow. Measure the distance from the floor to the maximum height and divide by 2. Most plants close to double in size while flowering. So, send them to flower when they reach 50% of your maximum height. Works 4 me, BigSteve.

    Flower at 8 weeks

    You will see pre flowers

    You can switch whenever you want it all depends on how much room you have to work with. After you switch to flower the plant usually doubles in size or in some cases triples all depending on strain of course. Good luck.

    Why are you growing 6 plants in the same pot? And fuck yes they are too young. This is a case for "Research Man" !!!
