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.

10 Tall Weeds With Thick Stalks That Might Invade Your Garden

Anna Brown Added: June 17, 2020 Updated: June 17, 2020

Tall weeds with thick stalks are invading your yard or garden and don’t know what kind of plants are those? I made a list of plants with thick and tall stems to help you identify the intruders.

A few days ago, my friend has asked me if I can help him identify a plant with a thick stalk and large leaves that was growing in a corner of his yard. He didn’t know if that was a weed or some kind of tree. I didn’t know either because it was not a plant I’ve seen before.

Fortunately, I had a few apps for identifying plants installed on my phone and I was able to quickly find out the name of the weed by simply taking a photo of one of its leaves. That also gave me the idea of making a list of tall weeds with thick stalks that sometimes grow unexpectedly on someone’s property.

Some of these plants have more particularities, hence, they are easier to identify in any life stage. Others are harder to recognize when they are young.

While a blooming agave is probably the champion when it comes to plants with tall thick stalks, I have omitted from including it in the following list because it’s not usually a plant that simply pops in someone’s yard out of the blue.

So, here are some mysterious plants that could match this description.

1. Paulownia Tree

I have included the paulownia tree first because this was the mysterious weed growing in the yard of my friend.

Paulownia is one of the fastest-growing trees in the world and belongs to a genus of about 17 species of flowering plants in the family Paulowniaceae.

This plant is native to central and western China and is often used as a decorative plant in landscaping across the world.

In several regions of the US, shrubs from the paulownia genus are considered an invasive species due to their fast-growing nature. Hence, it is not unusual for these trees to expand even five meters in a single year.

When are only saplings, the paulownia tree can be easily mistaken with a gigantic weed if you’ve never seen one before. It has a thick and tall stalk and large flat green leaves.

When it matures, paulownia grows into a lovely flowering tree. Yet, during winter, it makes some brown fruits, which many find ugly.

2. Pokeweed

Pokeweed is a perennial weed in the Phytolaccaceae family, native to eastern North America, the Midwest, and the Gulf Coast, as well as to some European and Asian countries.

This plant has several other names such as phytolacca Americana, dragon berries, American pokeweed, or poke sallet.

Pokeweed holds a potent toxin, which is extremely poisonous to humans, pets, cattle, and other farm animals. Its fruits look like berries but are also very toxic. However, there are some species of birds and small animals that are immune to this poisonous substance and consume them.

The easiest way to identify pokeweed is by its fruits that look like berries, or similar to a black grape with small rounded grains.

When pokeweed doesn’t carry fruits, you should be able to recognize this plant by its thick purple stems with green-to-white flowers or lance-shaped green leaves.

Because its ability to spread quickly, pokeweed is considered an invasive and harmful weed. It can form dense bushes and overwhelm other plants. Plus, due to its toxicity, it’s a real threat for children, pets, and livestock.

3. Sunflower

Common sunflower is a large annual herbaceous flowering plant generally grown for its seeds. It is a part of Helianthus, a genus including about 70 species of plants.

Everyone has chewed sunflower seeds, but there are many people that cannot identify a sunflower plant without seeing the well-known yellow flowering head that turns after the sun.

There are multiple varieties of sunflowers, some with varying colors for the flower heads and different sizes.

You can usually identify the Sunflower plant by its stem, large rough heart-shaped leaves, and flowering head. The stalk is thick, has a green color, grows upright, and is usually covered by a thin coat of hair.

Besides the production of oil and food, some species of sunflowers are also used as ornamental plants in landscaping.

4. Ricinus

Ricinus (Ricinus communis), also known as the castor bean or castor oil plant, is a fast-growing perennial shrub in the spurge family. It is a plant native to Asia and Africa and grown as an ornamental plant in many parts of the world. Ricinus can reach the size of a small tree, about 12 m (40 ft), in hot climates.

Despite its pleasant appearance, Ricinus is one of the most poisonous plants in the world. All its parts, especially the beans-like-seeds, contain a deadly naturally occurring toxin called “ricin.” Ricin can be lethal for both humans and animals.

You can typically recognize this plant by the following particularities.

Ricinus has a thick stalk, which is usually of a purple-to-reddish color. It has large glossy leaves, similar in shape with an open palm that has about 5 to 11 fingers, with prominent centered veins that unite with the leaf stem. The color of the leaves is typically dark reddish-purple when the plant is young and gradually changes to a dark green when the plant reaches maturity.

Its fruits are spiny green or reddish-purple capsules that contain large, oval, bean-like seeds with different brownish patterns.

Castor bean is considered an invasive plant in several countries, particularly in the tropics.

5. Japanese Knotweed

Japanese knotweed, also known as Asian knotweed, Japanese bamboo, or Reynoutria japonica, is a large perennial plant indigenous to Japan, China, and Korea. It was assumedly introduced to the United States and Europe in the 1800s as an ornamental plant. It became trendy due to its bamboo look and because it didn’t have extraordinarily demanding growing requirements.

The identification of Japanese knotweed is not always straightforward, especially when they are young. Several other plants can be easily mistaken for being knotweed because of the similar appearance of leaves and stems.

A mature plant has hollow robust stems with distinct raised nodes similar to those of bamboo. These can grow up to 13 ft (4 m) each season.

The leaves of Japanese knotweed are green, oval with a truncated base. The flowers are tiny, white or cream, produced in upright racemes in late summer and early fall.

Japanese knotweed is considered an invasive plant and has been listed on the noxious weeds list of many US states due to the danger it poses for the native plants. It likes to grow in dense bushes, crowding out the native plants and eventually killing them.

6. Wild Lettuce

Wild lettuce is an annual or biennial herb in the family of Asteraceae (same family as dandelions). It is widely considered a weed and is the closest wild relative of cultivated lettuce.

Wild lettuce is native to Europe, North Africa, and Asia, but has quickly spread almost everywhere. There are several varieties of wild lettuce. Two of the most popular are Lactuca virosa and Lactuca serriola.

This weed can reach an impressive size about the maturity time. In the proper climate, it can even grow to 7 or 8 feet (2 – 2.5 m) in height.

The plant develops a single tall stem wich becomes more robust once with age. Depending on the variety, it can be sometimes covered with thin spines. The color of the stem usually varies from one species to another, and it can be greyish-green, green, purple, or brownish-red.

The wild lettuce leaves are green, elongated, and have serrated edges (excepting the ones at the bottom of the plant). On the inferior side, they have a strengthened vein along the midline that has spikes on its entire length.

Wild lettuce contains a milky sap that has analgesic and sedative effects.

7. Giant Hogweed

Giant hogweed (scientific name Heracleum mantegazzianum) is a perennial flowering shrub in the family of Apiaceae (same family as carrots). This plant is indigenous to the western Caucasus region of Eurasia. Just like many other weeds, Giant Hogweed has spread as an ornamental plant to numerous countries, and it is now on the noxious weed list of many.

The name “giant hogweed” gives us an excellent representation concerning the growth potential of this plant. Hence, if it has the proper environmental conditions, it can reach even more than 18 ft (5.5 m) in height.

Giant hogweed has a stiff stalk that can grow more than 4 m (13 ft) high and up to 10 cm (3.9 in) in diameter. A mature plant has gigantic incised and intensely lobed leaves that can reach between 1 and 1.5 m (3-4 ft) wide.

This plant is also easily identifiable when it’s in the blooming period due to its sizeable white inflorescence that consists of multiple short flower stalks that spread from a central point, similar to an umbrella.

Because it looks very similar to cow parsnip, a plant from the same family, these two are usually easily mistaken with each other. The difference between these two plants is that giant hogweed grows larger than cow parsnip, has sharper serrated leaves, and has purplish spots on the stalk.

8. Creeping Thistle

Creeping thistle (Cirsium arvense) is a herbaceous perennial plant in the family of Asteraceae with origins in Europe, western Asia, and northern Africa. It later spread in many other regions of the globe.

This plant can typically grow up to 1.5 m (5 ft) height, forming vast clonal colonies from the expanded root system that send up several vertical shoots throughout the growing season. Its stalks are smooth, green, branched, and mostly lack spikes. The leaves are typically dark green, lobed, present many thorns, and can grow up to 20 cm long and about 3 cm wide, their size gradually decreasing in the upper part of the plant.

The flowers of creeping thistle are of a pink-purple color, all have a similar form, and are composed of many thin petals.

Because of its adaptive nature and with seeds that are dispersed by winds, creeping thistle is seen as one of the most invasive weeds globally.

9. Common Mullein

Common mullein (Verbascum thapsus) is a biennial plant original to Europe, Asia, northern Africa, and introduced in the US and other countries.

The first thing that can help us to identify this plant is by its velvety leaves. Because of this quality of his, some commonly refer to mullein as “cowboy toilet paper.”

During the first year of life, the plant only produces a rosette of leaves on the ground, and only in its second year, it develops a stalk that can grow up to 2 m (6.5 ft) tall. This ends in a dense inflorescence that can occupy up to half of the stem length. The flowers are yellowish and have very short pedicels.

A layer of hair covers all parts of the plant, giving these plants a silvery appearance. However, the densest is found on the surface of the leaves.

Common mullein spreads by prolifically producing seeds, and while it doesn’t represent a problem in many areas, it has become invasive in the temperate climates where it grows the best.

10. Himalayan Balsam

Himalayan balsam (scientific name Impatiens glandulifera) is also commonly known as policeman’s helmet, copper tops, gnome’s hatstand, Ornamental jewelweed, Indian jewelweed, bobby tops, touch-me-not, as well as a few other names.

It is a large annual herbaceous plant native to the Himalayan mountain range in Asia. While this plant can tolerate various types of soils, it habitually prospers on the banks of rivers. However, it can also be found in forests, wetlands, sides of roads, and can even occupy people’s yards or gardens.

Himalayan balsam normally reaches up to 2 m (6.5 ft) high. It has a green or slightly red stem that thickens when the plant reaches maturity. The leaves are lance-shaped with a pointy top. The flowers are typically pink or white, with a hooded shape. Hence, its popular name of “policeman’s helmet.”

After the flowering season, Himalayan balsam forms seed pods that pop when something touches them, dispersing the seeds up to 7 m (23 feet) distance.

Impatiens glandulifera endangers some of the native species of plants and alters the behavior of the pollinating insects. Hence, it is regarded as an invasive weed species in many areas.

Final Word

These are ten plants with a tall thick stalk that might pop up in your yard or garden without your allowance. The list could probably go on and on since there are a lot of other weeds that would fit these criteria.

Hopefully, this post will help someone identify a mysterious plant growing in his or her yard one day.

If you still cannot find an enigmatic plant among the ones in this article, I recommend you install a plant identification app (check out my list of best apps here) on your phone and simply take a photo of a leaf or another part of the plant. That should help you recognize the plant in no time.
