You can plant marijuana outside in the late spring all the way through to the middle of July. Planting earlier basically ensures a much bigger plant. Starting late can prevent the plants from getting too large before flowering begins. The plants can be placed in garden soil where they generally do very well, or they can be grown in five- to twenty-gallon containers. Plants growing in larger containers will naturally produce more bud.

Pruning is sometimes a necessity to keep the marijuana plants at a manageable size. When the main stem is cut, the lower branches increase in size, and the plant grows several other strong branches. When these are pruned, the plant becomes bushier and puts less emphasis on growing taller. Plants with the main stem clipped will produce greater yield than un-clipped plants. Download my free marijuana grow bible for more tips about growing marijuana plants.

Fertilize the plant with vegetable fertilizer mix or liquid, or use a hydroponic, vegetative formula to maximize plant growth and yield. Follow directions precisely or use less fertilizer than suggested. Never use more than the suggested amount as it can throw chemical balances out of order.

The lengthening nights of the late summer trigger the plant’s flowering stage. Some varieties will cease growing vegetatively almost instantly, but others could continue growing and quadruple in size. It generally takes between 55 and 70 days for the buds to mature after the plants have started flowering. When the plant starts flowering, switch the fertilizer to a bloom formula so that the plants will acquire nutrients needed for larger buds.

Marijuana plants switch to flowering when the uninterrupted dark period exceeds the critical time period. This period varies by variety and is usually between 8 and 11 hours. If your plants respond to a shorter dark period, they are early season varieties. Plants that respond to a longer dark period are, of course, late season varieties. Outdoor plants with a short dark period are best suited to higher latitudes.

When growing marijuana, you must account for the effects of latitude on day length. For example, June 21 is the longest day and shortest night of the year. In San Diego, dusk to dawn lasts 8 hours and 44 minutes. In St. Louis, it last 8 hours and 3 minutes and, in Boston, it lasts 7 hours and 32 minutes. As you can see, Boston’s night length is 1 hour and 12 minutes shorter than San Diego’s.

Early season varieties growing at lower latitudes (a la San Diego) will be induced to flower early in the season and will remain small even during the maturation process. The generally shorter nights during the summer at high latitudes (a la Boston) give the plants a chance to grow before they flower. A late season variety growing in the north might trigger late in the season but won’t get a chance to develop mature buds. It will not trigger during the early summer in low latitudes but it will flower earlier as a result of the longer nights and milder climate.

Marijuana’s disparate flowering habits and the varieties that produce them have led to many strategies for growing. In northern areas, short season varieties are a necessity to ensure that plants mature before the weather turns.

By contrast, gardeners in the south grow long season varieties during the summer that ripen in the fall. Certain short season varieties will start to flower soon (a month or so after the summer solstice) and will be ready for harvest in early autumn. If short season varieties are not provided with extended exposure to daylight, they will not grow large enough to produce much of a yield. Long season varieties can be planted in the fall to mature a few months after planting.

In areas that tend to stay warm throughout the year, sativas and sativa-indica varieties can be planted in the fall. They will continue growing into the winter as they flower and will be ready in about 70 to 80 days after planting.

Regardless of the latitude you live in, you can trigger the flowering stage at any time during the summer by covering the plants for a portion of each day so that the “night” period is lengthened. For example, if dusk is at 8:00 p.m., the garden needs to remain enshrouded in darkness until 8:00 a.m. the next morning. With an opaque cover over the garden during the 12-hour dark period, the plants will only receive 12 hours of light every day and will thus be triggered into flowering.

Around week six of flowering, you will begin to notice that the buds are becoming more odoriferous by the day. The non-pollinated flowers are beginning to mature and, in two or three weeks, the flowers will be ripe and ready. This can be observed when the stigma dries, the ovary swells, and the capitate trichomes swell with resin and fluoresce. Buds that get the most light will ripen first in most cases. Remove them, but leave the unripe buds to continue ripening. They will be ready within 10 days.

    my first big grow ended in the catepillar take over they ruined my crop,,,,

    •  

      Marty, I feel your pain. The problem is a little white moth that is attracted to the smell of the buds. They land at night and lay eggs on the plant. Once hatched the little devils burrow into the buds to eat and grow bigger. They also poop inside the bud and that turns into mold which travels through out the bud destroying it. Now you have mold spores floating around and infecting other buds and other plants. It’s a two prong problem.
      The best you can do is try and save as much of the other non infected buds that you can. Cut off the infected buds and throw away. Disinfect the scissors with alcohol after each cut so you don’t transfer mold spores around. There’s a caterpillar dust made by “Safer” that will kill the worms, but the bugs have to ingest it through eating. It kills the caterpillars from the inside and is non toxic and dissipates after a few days. So repeated applications will be required. Good luck it’s a fight.

      Neem oil and a magnifying glass daily would have prevented all that.

    My plants are flowering

    •  

      What did you learn that’s the import thing we need you to tell us that.

      •  

        They were outdoor plants and I use Miracle Grow and I think I over did it . I just watered for a few weeks and that seemed to solve the problem. Also when the problem was happening there were 4 days that were over 100 degrees so that could have been a factor. The harvest went well and although I planted very late I still got 11 oz. from 3 plants. I top them every 4th set of leaves on the whole plant until flowering to increase my yield. Thanks for all the input. Can’t wait for this harvest!!

    My plants are flowering and on one of the plants some of the leaves have some brownish-rust color on them. But the weirdest part is that some of the leaves are turning themselves upside down? Any ideas-advise? Thanks

      Heat stress, and boron deficiency is the problem. http://www.growweedeasy.com/marijuana-symptoms-pictures

      •  

        Boron came to my mind too. Good call.

      •  

        List to Iris and educate the more you know the more you grow. My plants are 1/4 pound a 5 gal bucket 600 watt light growing 4 plants. But I am patient and will let them run way longer than 4 months for powerful meds.also bottom leaf maturity.

    •  

      Over feeding boron deficiency i could tell you how to fix it but you need to get a book and read it. But flush with distilled water. Normally i’d tell you how to distill your water but go buy 5 gallons and run it through you’ll see pee yellow water running out into the drain. Let it bounce back cut you food into 1/4 of what you were feeding assuming it’s a good food. What are you doing for the soil that it ended up that way do you check your ph levels i have a feeling you don’t.do you know what those #’s r 2 b?

  4.  

    you can use a chemical called cypro it keep the plant green an beautiful 10ml per gal frostogen put that heat in the roots i plant hot peppers an the same treatment applys to both plants an if u have no insecticide you can use your first morning urine mixed in water its natural an wrks an crushed oyster shells is also a natural source of calisium

    Also, if you need to top a plant(for damage or just to tall) take the top and trim off the fan leaves. Cut the stem at a 45 deg. angle and stick it in some most soil, covering a node or to. In about 10 days it will have rooted and you have a new plant to put outside!

    Should I pull up my 10 week old male (seeding) plant that is in the middle of my budding female plants. I was told my male plant will affect my other plants?

    i am a new grower and have 4 plants I have 2 that are tall and 2 that are short. The shorter plants leaves seem to be closer together. Why? Also on all 4 there are only 3 leaves in the fan not 5 Why am I doing something wrong? I still am not sure whether the plants are male or female?

    •  

      You need some books on plant variety around 6 weeks into the plants life pistles will sprout at the branch joints look up pistles the male has a seed sack the female doesn’t your plant may be of two variety’s an indica and sativa usually when the growth of a plant has alot of space between leaf sets its because you are not running your lights right. I veg 24 hours lights on and alaska lighting if you will speeds up my grow much stronger roots bigger production 1/4 l b per plant in 5 gal containers 1 600 watt super lumen digital light. There’s nothing wrong with t5’s high watt but you can’t crimp on the $.put a box under the shorter plants to compensate.

      •  

        “the male has a seed sack”? Back to the text books for you mate. Male pods only carry pollen, never seeds. Only females ( or herms) create seed.

  10.  

    also do you have to use fertilizer

    •  

      You are feeding your dirt not your plant dirt is everything learn about amending organic soils.This will produce worms and worm castings micro and macro neuts you find this info on Youtube but find it from educated sources. Less is always more. Black strap mollasses during flowering as opposed to chemicals that break down good carbs during flowering like Fox Farm are very harmful. But they have good vegitative line ups for the beginning of your grow cycle. Enzymes are important to carry the material to the plant. Neem oil is a great foliar feed and insecticide organic and can be used up to the end of grow but i would still cut out all processes 10 days prior to harvest and just water reduce room temps and the ladies will shut down on their own.

    I started my plants inside then put them outside and they started t0 go t0 bud. what is the best thing to do now that they are back to growing correct again?

  12.  

    hi some of my flowering buds have a black tinge to them whiles others on the plant are not dark…i have them in potting bags, i thought maybe the roots at the bottom weren’t drying out enough…so i put some thin pieces of wood underneath so they wouldn’t be touching the ground…also alot of the lower leaves are turning yellow, is this too much water?…thanx in advance for your answers! :)

Its a outdoor plant. HELP PLEASE!!

    •  

      Is it in the ground or a container if in a container 1 of 2 things i would flush no more food get some neem oil pure not that Safer crap it will be gold oil in a small jar mix 1tsp to a gal warm water add lemon liquid soap 1 tsp also keep mixing it well in a sprayer.spray under and over. This is a fungicide and insectice do it 3 apps every 3 days.then wait and see her bounce back.

    •

    I’m in northern Virginia and my outdoor plants are budding. There are red and white hairs and under a microscope the crystals are not fully milky yet but the leaves are slowly dying. What are some other ways to tell its time to harvest? Is it better to harvest too soon rather than too late? Thanks and happy harvests to you all!

  16.  

    How long does the plant take to finish flowering

  17.  

    Is it too late to move to bigger pots ( more soil) my husband has had my colon bud growing in a little 1 gal container and I know it stunting its growth.

  18.  

    Does my plant need 12hrs light/12hrs pitch dark for flowering stage

    Thanks for the free PDF guides! I live in Eugene, Oregon, as you know it is legal to not only buy, smoke, and consume cannabis, but also grow plants now. This is awesome! Even better you can bypass the whole germination process as they sell starts in many varieties. However, I want to grow some plants in my backyard. My problem is I don’t know when to plant them in the Pacific Northwest. I read late spring but I am not sure for my zone if that is the same. This is all so new (it being legal in the state) that there isn’t an easy site to go to that shows your zones and when to plant the starts unlike the many sites that describe say, when to plant tomatoes. If you could help I would be very grateful.

    I too live in Eugene Oregon and I’m starting my seeds now and putting them under metal halide untill beggining of April where I’ll go outside. You need 13 hours of light to veg outdoors so Google search “Eugene Oregon how many hours of light right now” and you can start to find the info you need it’s all recorded daily. You must go outside slowly though seeds or clones or teens they can only go out for few hours at first then more and more and then they’ll be ready to be outside permanently untill harvest. We are actually 15 minutes away from 12/12 so right now if you went out plants would things it’s time to flower. Early April we should be around 13/11 14/10 and ready to go outside now if your not looking for huge monsters or are a beginner i would read up on outdoor growing strategies and I would probably start in May. Get your plants as much light as possible give them good soil and support her limbs and she’ll produce. Watch out for bugs and don’t let her dry up this summer April=massive may=large June=hide able from neighbors.

    I have a plant that is about three feet tall and still no results to flouring yet it is in a little green house I built outside and is in the light for about 8 hours a day and has plenty of water but I have not seen any signs of flooring yet can someone help me understand why before my other plant gets any bigger. I am only growing one plant right now I am just starting out on trying this I live in southeast Washington state

    I grew my first set of weed along with tomatoes, egg plants, etc. last year. What I discovered was I did alright.
    All my plants did alright for the most part. Let’s get to what I want to ask. I had two plants less than 24″ tall but
    got at least 9 dry ounces off each. I pruned every two pair of branches and fertilized the plants like I do my lawn. When it starts to burn I just water. A couple days later all is OK. But a lot. I just realized when my mom cut the plants
    because it was growing to big she set the height limit at under 2′ and that’s when they started to flower. Secret. Ha-ha. I don’t think anyone wrote or knew about how to get such
    a yield from a 2′ plant. People who don’t have much space can really benefit from this. Timing would be the most important which I wouldn’t know much about but if you can add to this it can turn out pretty good.

  23.  

    Rabbits or I’m guessing rabbits raided 2 of my plant’s today and chewed off the lower branches and stripped the bark from the main stem,is there anything I can do to save the lower plant once bark has been stripped off_,,,,?
