Everyone loves large marijuana plants, but they sometimes get too tall. It is not a good thing especially if you cultivated them in a restricted area. Even a stealth outdoor cannabis grower will not be happy to see his marijuana seeds Canada growing taller than the expected.
This post will tell you what to do just in case this issue happens to your cannabis plants. Read on to find out how you can effectively control the overeager cannabis plants from growing taller and taller.
When Marijuana Seeds Canada Grow Too Tall
If you leave your marijuana seeds Canada exposed to good growing conditions, then they must fulfill their genetic potential. At times, it means that the plants will thrive too tall. It can easily take place with cannabis sativa plants which stretch substantially and to Kush varieties which have the tendency to develop generous spaces between the nodes.
Some cannabis species stretch too much once they move to the flowering stage. The same case can happen even while they are on the vegetative phase. These plants tend to have twice the normal height they should have.
Growing taller cannabis plants sounds a good idea. But these plants can be very inconvenient to grow depending on the scenario.
If you grow cannabis plants indoors, your primary concern will be the limited space to grow them. In this situation, overgrown marijuana plants can exceed the grow room’s height. If you are growing different strains of cannabis, elevating the lights for the benefit of taller plants may deprive the shorter plants of adequate lighting.
The County of Sonoma recommends growing medical marijuana strains in a wide area measuring 100 square feet. If you choose to grow recreational marijuana strains, grow up to 6 plants.
When you cultivate cannabis outdoors, overgrown plants may sacrifice your privacy as they can attract attention. Controlling your plants’ height is not actually difficult, and you can do it in different ways. Here are some techniques which can keep your plants’ height under control.
#1. Think About It in Advance
If you’re aware that the cannabis strain you’re growing has the tendency to overgrow, then you must start controlling the plant height within the early vegetative stage. Otherwise, the size of the grow space might require effective height control regardless of the strain you choose to grow.
Fimming or topping when cannabis plants are young promotes a shorter but bushier plant. However, grow room space still requires consideration as you’re exchanging the height for the floor area.
You should prioritize air circulation when cannabis plants become shaggier in constricted quarters. Controlling your plants’ height just to suffer from fungus or mold because of poor circulation is a big no.
Why not try lollipopping your cannabis plants? It guarantees proper air circulation underneath the canopy and prevents the pathogens from destroying your crop. Also, it will guarantee the perks of having weightier and chunkier colas with less unpleasant popcorn buds.
#2. Low-Stress Training
LST is the practice of gently tying the twigs of your cannabis plants to encourage them to grow horizontally. In doing LST, you have to tie the biggest stalk to encourage the side branches to become dominant. At the same time, you have to tie the side branches.
If not, you may top the plants several times and tie down the new growth in a mainlining style. Mainlining and LST have the advantage of exposing further the plants to light, thus promoting weightier buds all over.
What is good regarding these techniques is the flat and smooth canopy instead of the main cola. The most popular is ScrOGging. This technique encourages the entire plant to grow horizontally.
In this technique, you need a mesh screen for holding down the new growth until you see the plants forming a mat. You can call it the “screen of green” or 1 or 2 plants might fill the whole grow space.
#3. Pre-Flowering Topping
Allowing your cannabis plants to thrive on their own throughout the vegetative stage and topping them before the flowering process begins will also help control their height. When the plants are about to move into the flowering phase, you should top the branches. It comes with the impact of reining within the bud stretch. Your plants will produce new flowers instead of spending their energy in stretching out.
Occasionally, pre-flower topping should be a complete pre-flower pruning. When your plants fill the grow space throughout the vegetative stage, there’s no way there would be adequate room for flowering.
It’s time to get extreme. Aggressive pruning your cannabis plants to half the size and switching the lights to 12/12 flowering period. Marijuana is extremely hardy and will even recover from being reduced to the stem with just 1 or 2 leaves.
Marijuana plants transpire a huge volume of water. Cannabis prefers a humidity of 50 to 65 percent. If they grow too tall, humidity may become an issue as the cannabis plants consistently produce water vapor to the air.
Then, the water will gather on the leaves and on other surfaces within the grow room. potentially causing mold and other problems. When humidity becomes an issue, you can solve the problem in two ways. First, you can use a dehumidifier. Second, you may increase the power of your exhaust fan.
Defoliating may also help. It increases the airflow for controlling humidity. Remove the mid-level and lower fan leaves. It will increase light penetration to bottom flowering branches.
The same with humidity, when cannabis plants are getting too big, the temperature may escalate. Excessive height and reduced airflow may increase temperature and encourage the plants to be in close contact with the grow lights.
Cannabis grows if the temperature increases to 25 degrees Celsius. If the temperature goes more than that, plants may likely stretch. High temperatures may also affect the flower and leaf formations, including the potency and bud flavors.
#6. Light Intensity
When your cannabis plants are too hot or too tall and you have the room, just elevate the grow lights as high as you can. Keep in mind that putting the grow lights in the far distance from the top of the plants can cause stretching, too. Be sure to attain the right light positioning.
Adjusting the light intensity can also be a good method for controlling your plants’ speed, growth, and height. Some grow light models in the market have flexible outputs. When your plants become unruly, you must decrease the intensity. If you’re using two or more lamps, just turn off some of them.
Throughout the flowering stage, you can reduce the growth of your plants by minimizing the photoperiod – only when your plants are in the flowering phase within the last 6 weeks. Reducing stem stretching and leaf production can take place by minimizing the light period from 12 hours to just 10 to 11 hours.
