Growing giant marijuana plants may seem like an almost impossible task, but it is not like that because a gardener with the essential supplies who maximizes his yield can obtain a monster weed plant like the ones you see in magazines. In this tutorial, we are going to give you general tips so that you have the basic notions of how to grow your monster cannabis plant, either indoors or outdoors.

Never forget that practice makes perfect and if you add study and knowledge to that, you will achieve optimal results. In addition to reading this guide, look for additional sources of information to help you cultivate that monstrous plant that you want so much.

Select the right cannabis strain for you

First of all, for the cultivation of large cannabis plants both indoors and outdoors, it is necessary to select the right marijuana genetics. For this reason, it is good to point out that the mostly indica cannabis strains and the hybrids produce the heaviest harvests with good-sized and easy-to-grow plants that will not cause  a lot of trouble.

Here, we can highlight easy-to-grow strains such as Skunk Diesel, mostly indica genetics, and the new generation of strains including Critical Green Crack which is a hybrid cannabis strain. Other strains that are going to revolutionize the gardens of the world include the incredible indica, Blue Colombian Kush.

Measure the growing space

It is important to measure the space where you plan to cultivate because that way you can figure out the number of plants you can use. For example, in a space of 1m x 1m, you can have between 2 and 4 plants depending on the size of the pot. For outdoor cultivation, you can have cannabis plants in 25 liter pots and per square meter, you will have space for 1 plant.

If you are worried about the number of plants, don’t worry because in the following tips, we are going to teach you how to maximize the yield with some cultivation techniques. The larger the pot size, the larger your plant and harvest will be. With 50L pots, you can obtain the maximum size with specimens that can exceed 2 meters in height and harvests ranging from 400 gr to 600 gr of dried buds.

The size of the pot

The essential thing for the development of a giant-sized, monstrous plant is the size of its roots. That’s why, as we already told you, the selection of a large pot is essential. For this reason, we recommend using pots from 20 liters and up. If you want to grow in a larger pot such as 25 liters, you will be able to grow 5 giant marijuana plants in a space of 5 m2 either indoors, in a greenhouse, or outdoors.

If you take a 25 liter pot as an example, you will be able to obtain a considerable harvest from 200 gr to 350 gr of dry buds. This is a remarkable amount considering that with 5 plants in pots of this size, you will get up to 1 kilo of dry marijuana.

Healthy soil

It is essential to have good soil for cultivation and a good substrate must have an aerated texture so that the roots of the plants can develop properly to ensure good growth. In addition, the substrate must be rich in nutrients and must contain certain non-pathogenic fungi that help protect and enhance the roots of the plant. 

You can also make your own compost for cultivation. If you are a cannabis purist, this allows you to recycle all the organic waste from your kitchen and help the environment, avoiding contaminating it with more garbage. Good compost is usually made up of organic green matter as well as brown matter. A balanced compost that can meet the nutritional needs of a cannabis plant is composed of between 25%-50% green organic matter and 75%-50% brown organic matter. Natural Micorrizas fungis is ideal for the roots of a cannabis plant.

Fertilizer and Nutrition

Regarding fertilizers and nutrition, it is good to recommend that minimum or medium doses be used in each irrigation. At the beginning, it is best to promote the growth and strengthening of the roots and then move on to the nutrition of the plant and the development of its main stem, lateral branches, and buds during the flowering season.

In the first phase, a base rooting agent and a stimulant to protect the roots is sufficient. As the plant progresses, other fertilizers and enhancers can be applied. If you want to develop a homemade rooting agent, you can do so with the roots of lentils previously macerated in water. The roots of beans can also be used and in both cases, these homemade rooting agents will make the roots of your plants fatten and expand throughout the substrate in a remarkable way.

Time of Growing

In general, a giant plant outdoors can take up to 2.5 months of growth and even 3, depending on the genetics and its speed of development. On the other hand, indoors, you can grow a cannabis plant in just 4 weeks and then go into flowering. However, because you want to grow a giant marijuana plant, it will most likely take up to 2 months of growth as you will have to apply some techniques that can slow down development.

Many gardeners get impatient when they start to grow, especially the most novice cultivators. However, it is good to have patience because the growth and flowering of a plant is a waiting process. The growth time of a plant is relative depending on the way in which it is cultivated. A plant to which cultivation techniques have not been applied will tend to go faster than a plant that has undergone cultivation techniques such as Scrog, LST, or some types of pruning.

Techniques of cultivation for the giant cannabis plant

If you want giant, high-yielding plants then we recommend growing techniques like LST, Topping, FIM, Lollipopping and the ScrOG method. It is good to combine these techniques to obtain the maximum size, whether in an indoor or outdoor grow. Indoors, giant plants are ideal to grow with Scrog techniques and mostly sativa or hybrid strains are the ones that best adapt to this method. Also, SCROG is applicable outdoors and many gardeners use it vertically to control the lateral arms of giant plants to maximize performance.

At the same time, with FIM, Apical, and topping type pruning, you will be able to multiply the arms of the plants with which you will obtain more tips and much more robust and powerful buds in the upper part of the plant. For its part, the lollipoping techniques are intended for indoor use to help you control the size of the plant in case you do not scrog. You can also use it outdoors in case you want a gigantic and discreet plant that it is not seen outside of your area if you have a guerrilla grow.

Lights vs Sun

Indoor lighting and outdoor sun are essential when growing which is why it is recommended to use proportional lighting with respect to the growing area. So, a person who grows in a 1 m2 space can grow with 400 w or 600 w sodium lighting or its equivalent in LED lighting. If the space is larger, that is, 3 m2 can grow with 1000 w sodium lighting or its equivalent in led.

Regarding outdoor cultivation, it is good to point out that a plant peaks when it begins to go from growth to flowering when the natural light cycle goes from 18 hours to 12 hours, that is, at the end of the summer season. Remember that to ensure that your mutant marijuana plant is harvested in optimal conditions outdoors, you must be aware of the climate in your area in order to know when to plant and thus begin the entire cultivation process until the harvest without risking the buds.

Skunk Diesel

Skunk Diesel is a mostly Indica strain that was born from the crossing of NYC Diesel x Sensi Skunk. It is characterized by its great outdoor productions where you can harvest up to 550gr/plant. On the other hand, indoor growers who want a giant plant can obtain up to 450gr/m2 of dried buds.

As it is a strain that has Skunk genetics, it is easier to cultivate. For this reason, gardeners who wish to have an authentic tree of this strain should not worry excessively about possible complications in the cultivation because it does not require much work. Another relevant detail is that the effect manifests itself in a relaxing and calm way, especially after a long day of work or when sharing with friends.

Critical Green Crack

This is another perfect variety to grow as a monster outdoors or indoors. Critical Green Crack is characterized by its large size that can reach 2 meters outdoors and indoors. The best way to control it is with Scrog techniques to achieve a large mutant plant. Without a doubt, this strain is easy to grow and does not provide many complications thanks to its Critical parent which also brings great bud production both indoors with harvests of up to 450gr/m2 and outdoors, reaching up to 700gr/plant.

For outdoor growers, cultivation techniques such as LST are recommended to control the lateral branches. It is also appropriate to apply defoliation in the lower part of the plant so that the upper tips gain strength and the flowers develop well. In this type of strain, it is recommended to have good ventilation and air circulation so that the buds are not affected by humidity, parasites, or harmful fungi. The use of diatoms and non-pathogenic fungi add more preventive controls throughout the cycle and are essential if you want to grow your monster plant outdoors.

Blue Colombian Kush

This girl will amaze you if you are a fan of Indica strains because her harvests are gigantic with 500g/m2 indoors and 550g to 600g/plant outdoors in a flowering period of 75-80 days. Despite being a mostly indica strain and having the classic round and bushy shape, Blue Colombian Kush can get you there. It grows up to 2 meters outdoors, so we recommend using cultivation techniques to obtain maximum yield.

For example, to maximize this strain indoors, you can use cultivation techniques such as Lollypop and LST, stretching so that the light penetrates its leafy foliage better. For outdoor gardeners, it is recommended to use cylindrical lateral mesh as a vertical Scrog to hold the lateral branches and thus help the plant allocate its energy to the production of the precious buds that give off flavors and aromas of Kush, lemon, and pine.
