In addition to making sure your plants are the proper height, you also want to train your plant canopy to be flat and wide before switching to the flowering stage. The best yields are achieved by filling the entire grow space front-to-back and left-to-right with a flat canopy because it lets all the buds be close to the grow light.

Although plants typically double in height after the switch, some particularly tall and short strains can stretch more or less than average! Always pay attention to what the breeder tells you about your strain and plan accordingly!
Most everything I read says to continue the Vegetative Stage until the plant is about 1/2 its desired height, then flip to Flowering Stage, because plants about double in height on average.

  • If you have a “tall” strain, switch to the flowering stage earlier than recommended (1/3 the final desired height)
  • With a “short” strain you should wait until the plant is taller before the switch (3/4 the final desired height), to ensure the plant is tall enough after it’s done stretching.

  • LED Grow Lights– Unfortunately, this depends a lot on the model. It’s partially a matter of trial and error because there’s no “standard” with LEDs like there are with other grow lights. A good rule of thumb is to take note of the length of your main colas after the switch to 12/12 (from a previous grow), then try to initiate flowering with your new plants when they’re about that height. So, if your main colas end up around 12″ long, initiate flowering when the plant is 12″ tall, etc. But if you aren’t sure yet, I recommend just sticking to the “half the final desired height” rule with LEDs, because that ensures that at least the plant will fit in your grow space and you’ll be able to learn what to expect from your LED model.

    So, now that you know that you can grow plants indoors for as long as you want, and that outdoors marijuana plants grow a larger branch structure, the question is: What would happen if you let your plants have a long growth period and then took them outside to flower?

    Growth timing is definitely a key element when trying to grow large plants due to the fact that once your plants move on to the flowering stage, they tend to get a lot bigger. This means that the bigger your plant grows during its growth stage, then the more they will develop during the flowering stage.
    Staking plants is essential if you want them to develop correctly and constantly, so you’ll need to start doing it during their first few days. You’ll need to start by staking the trunk and then wiring the branches that grow, which will give a higher yield thanks to being held up.

    When you grow your plants indoors and then take them outdoors they go from getting 18h of light a day to getting a lot less, so they immediately begin flowering. If it’s still growth season your plants will begin budding but then they’ll revegetate, losing potency in the process which is something you want to avoid, especially with a crop like this that takes a lot more work.
    However, if you take your plant outdoors to flower when the sun begins to set earlier, your plants will begin flowering normally and should be ready around the same time they would be ready if you had planted them outside from the beginning. The obvious difference is that these plants will be much larger and have a much higher yield; by using this method you can get plants that are over 4m tall.
    Indica and sativa hybrids obviously have characteristics from both genotypes, although depending on the strains used to create the hybrid and the percentage of indica vs sativa, they’re more likely to have certain characteristics. Generally, the biggest specimens will have a sativa percentage of over 60%; if the plant is indica-dominant then the specimens will be more compact but with a larger branch structure.
    There are also growers that like to fill their crop area with just one plant, giving it an enormous growth period as well as a large flowerpot; this makes for plants that would leave outdoor growers astonished. Some seed banks keep mother plants for over 10 years, so we know that you can give your plants all the growth time you want and rest assured that they won’t die (if you take care of them properly).
    For outdoor crops, growers have to depend on the seasons and the climate for their plants to switch periods, whereas indoors the grower decides when to change the light period, allowing him or her to choose how big their plants should grow. This means that indoor growers can play around with the number of plants and the timing of their crops; with a shorter growth period you can have more plants. This is how SoG systems were born; cuttings don’t need a growth phase and seeds only need two growth weeks.

    Cannabis crops are some of the most versatile crops on the planet, capable of adapting to almost any growers needs thanks to the amazing variation in how long some strains take to grow versus others. You can find spectacular autoflowering strains that are ready to cut in just about two months of cultivation, and then you can also find seasonal strains that need certain photoperiods (periods of light and darkness) to grow and flower. Today we’re going to talk about some tips and tricks to grow gigantic marijuana plants; to do this they’ll need a longer growth period and a whole lot of care, but you’ll be rewarded with the biggest specimens that you have ever seen.
