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.
Many growers have already seen astonishing images in which American growers are standing beside incredible 4 or 5 meter tall marijuana trees with an enormously dense branch structure that end up looking like big green balls. This phenomenon is quite typical in Humboldt’s seed catalogue and other American seed banks, as well as professional growers books and of course thousands of images and videos online.
Choose a good strain
Choosing a strain with a decent growth level is essential because your plants entire structure will depend on this specific characteristic. Sativa strains tend to have a much larger growth as well as a larger distance between nodes and a thinner, taller structure. Indicas, however, grow into more manageable plants with shorter distances between nodes, more branches and a stronger central stem.
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.
Make sure they get a good growth period
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.
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.
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).
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?
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.
Increase the number of branches through pruning
If you use the previous method it’s not hard to get gigantic plants, but large plants don’t necessarily have a lot of branches. If you’re looking to increase the number of branches on your plants then you’ll need to consider pruning them.
It’s actually quite common for indoor growers to prune their plants every now and then when they’re employing a long growth period. If done properly without stressing your plants too much, then your plants should grow various new branches per pruning. All you’ll need to do is use a revitalizer on your plants to reduce stress and a couple of weeks after pruning more branches will have grown. If you’re thinking of using a growth period of a few months then you’ll have enough time to repeat this process a good few times. Once they begin flowering the amount of branches will obviously be higher, making your plants incredibly leafy and bushy.
Stake or string your plants to increase strength
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 your plants have reached the production levels that we were talking about before, the stakes or string you’re using might not be strong enough to put up with the weight of the branches and buds; one of the most recommended systems is by using metal meshes. By doing this you can hold up each branch individually and with less stress on the mesh due to the fact that the weight of the plant will be evenly distributed. It’s also pretty easy to set up, all you have to do is extend the mesh over your plant, placing each branch in a hole making sure that light can still access all of them.
So, now you know that if you want to get monstrously huge plants you have to consider the strain, give them a much longer growth period, prune selectively, and make sure that it can deal with the weight of all of those amazing buds. If you follow all of these tips you’re guaranteed to produce enough per crop to keep you going in between seasons. We recommend using organic fertilizers to increase flavor and cannabinoid levels in your plants, so that way your gigantic marijuana plants will have an extremely high production rate as well as powerful and flavorful buds.
Learn how to grow gigantic marijuana plants, you'll get an enormous yield without using any chemical fertilizers that could alter the final product.
What To Do When Your Cannabis Plants Grow Too Tall
Everybody loves big cannabis plants, but sometimes they can get too tall. This is bad news in a restricted space or for the stealth outdoor grower. Find out how to control your overeager marijuana plants with this informative blog from Royal Queen Seeds.
WHEN CANNABIS GROWS TOO TALL
When marijuana is exposed to prime growing conditions, it should fulfill its genetic potential. Sometimes, this means your plants will grow too tall. This can easily happen with sativas that stretch substantially or Kush varieties that tend to have generous distances between nodes. Some species of cannabis stretch notoriously when they enter the flowering phase, even doubling their vegetative height in some cases. Although the whole idea is to get the largest of plants with the heaviest yields of mature flowers possible, depending on the situation, plants that are too tall can be inconvenient.
Often, space is limited indoors and plants that are too tall can exceed the height of the grow space. If the grow room is a multi-strain grow, raising the lights to suit the taller plants can deprive shorter plants of sufficient lighting. Outdoors, especially in stealth grows, plants that are too tall can attract unwanted attention. Controlling the height of your marijuana plants is not very difficult and can be done in a number of ways. Here are a few techniques that can keep the height of your marijuana under control.
If you are well aware that the strain you are growing is going to be tall, then height control starts in the early vegetative phase. Alternatively, the size of your grow space may require height control no matter the strain. Topping or fimming when plants are young encourages a shorter, but bushier plant. Grow room space still needs to be considered, however, as you are exchanging height for floor area.
Air circulation is a priority when plants become bushier in tight quarters. Controlling the height of your crop, only to suffer from mould or fungus due to lack of circulation is definitely a no-no. Lollipopping your plants will guarantee good air circulation below the canopy, preventing pathogens from taking hold. This also has the added bonus of chunkier and weightier colas come harvest, with less unwanted popcorn buds.
LST or low stress training is the art of gently tying the branches of your plants to grow more horizontally. Either the main stem is tied down, encouraging the side branches to be dominant, after which the side branches are also tied down; or the plants are topped a number of times and the new growth is tied down in the mainlining style. LST and mainlining have the benefit of exposing more of the plant to light, therefore encouraging weightier flowers all over.
What’s great about these techniques is an even canopy instead of one main cola. The extreme of this style is ScrOGging, in which the whole plant is encouraged to grow horizontally. A screen of netting is used to hold down all new growth until the plants form a mat. Appropriately called “screen of green,” one or two plants may fill an entire grow space.
Letting your plants grow untouched during the vegetative phase, then topping just prior to flowering also controls height. When your plants are about to enter the flowering stage, top all branches. This has the effect of reining in the flower stretch. The plants are urged to produce new flower growth instead of focussing energy on stretching out.
Occasionally, pre-flower topping needs to be a full pre-flower pruning. If your plants fill the grow space during the vegetative phase, there is no way there will be enough room for flowering. It is time to get drastic. Aggressively prune the plants to half their size and switch lights to the 12/12 flower cycle. Don’t worry, cannabis is very hardy and can even recover from being reduced to a stalk with only one or two leaves remaining. Try not to beat yourself up about the loss of time and reduced final yields. All lessons are good lessons on the way to becoming a weed growing expert.
Cannabis plants transpire a substantial amount of water. Marijuana prefers a relative humidity (RH) of 50-65%. When they get too big, humidity can become a problem as the plants constantly release water vapor into the air. Water then gathers on leaves and other surfaces in the grow room, potentially causing mould and other issues. If humidity is becoming a problem, the use of a dehumidifier or increasing exhaust fan power can help. Defoliating can also increase airflow to control humidity. Remove lower and mid-level fan leaves only. This has the added benefit of increasing light penetration to the lower flowering branches.
As with humidity, when plants get too big, temperature in the grow-op can rise. Reduced airflow and excessive height can drive up temperature and position plants too close to grow lights. Cannabis thrives when the temperature averages 25°C. When temps exceed this, plants are more likely to stretch. High temperatures can also affect leaf and flower formations, as well as final bud flavours and potency.
If your plants are getting too tall or too hot and you have the room, simply raise the grow lights as high as possible. Remember, lights that are too far from the tops of your plants can also cause stretching, so make sure to achieve the ideal light positioning.
Light intensity can be adjusted as a method for controlling growth speed and height. Some grow lights have adjustable outputs. If your plants are getting unruly, reduce the intensity. If you are using more than one lamp, simply turn some off.
During the flowering phase, growth can be controlled by reducing the photoperiod – but only if your plants have been flowering for at least six weeks. Reducing leaf production and stem stretching can be achieved by reducing the “lights-on” period from 12 hours to 11 or 10 hours.
Appropriate strain choice can help avoid height issues before they even arise. If you have limited space, your dreams of cultivating a classic sativa will need to remain just that, dreams. Stout indicas and hybrids or autoflowering genetics can keep heights under control. Many autoflowering strains are ideal for indoor growing as they have relatively no vegetative period. Some strains will not grow taller than 50cm, but will still provide excellent yields per m².
DON’T WORRY, BE HAPPY
With a little bit of consideration and forethought, height need not be an issue when growing marijuana. Some research into strain characteristics is the first, very important step. Then, appropriate growing techniques will make sure you get lots of yummy buds with no drama. Happy growing!
Cannabis is a hardy plant that can grow too tall for your grow space if you just let it go. Sometimes you need to take charge to keep things under control.
