How to grow big cannabis plants

Updated: December 5, 2021

When growing cannabis plants, there are many variables to consider in order for plants to grow as efficiently and of course BIG as possible. Here are some tested solutions to help you figure out what are the best ways to grow BIG cannabis plants and get huge yields.


Nutrients are an important factor in the metabolism and overall strength and structure of your plants. There are two groups of nutrients known as micro and macronutrients. Microelements are composed of the primary nutrients nitrogen, phosphorus, and potassium and are the most commercially known. However, there are a number of trace elements that must be available and in balance with plant growth at the molecular level. Macro elements or "trace elements", as they are known, consist of calcium, magnesium, boron, zinc, sodium, manganese, sulfur, and copper. If you make sure that your growth medium has a healthy balance of micro and trace elements, this will allow your plants to grow with real and abundant growth.

Cultivation media

As stated above, the growth medium must contain all the basic building blocks that the roots must absorb from the food. Not only do you want to consider a growth medium that is airy, lightweight, has excellent water retention and high drainage capacity. It is important to look at the medium from another perspective and consider the nutritional value of the medium and how that medium retains nutrients, which it retains and which it does not. Thus, you can increase growth if you are aware of the nutritional side and texture of the medium.

A very user-friendly and organic medium is a blend of coconut fiber, worms, perlite, vermiculite, dried seaweed and some compost additives. In terms of drainage and medium consistency, coconut fiber, perlite and vermiculite will allow air pockets throughout the pot, while the rest of the castings will blend into a smooth mixture that can be obtained with molasses and other carbon-based liquid feeds.

Training your plants

There are various techniques that are classified under low stress or high stress. The low-stress technique is to tie the plant to the ground with a string. This encourages the canopy to grow wide and bushy with several main shoots growing from the top of the canopy. Another low-stress workout is to press the tops of the growth tips so that two new shoots can appear. Another technique is like pinching the strings.

High voltage techniques or high stress are more demanding, as they require pressure on the cell walls. You can do this with a simple press, with your finger and thumb, press until you feel and hear a bang or create the feeling that you may have slightly squeezed the stem. The walls of the inner cells will now be repaired with the calcined joint where the original fracture took place. This technique is called super cropping and is very beneficial as the plant will send natural growth hormone by itself to repair deviations.

Large roots mean larger buds

The complexity and integrity of the roots are often overlooked because we only see what is above the growth medium. As we delve deeper into the medium, we will notice a network of root hairs and beneficial bacteria working together in a symbiotic relationship. The large root area allows the plant to be better watered at maximum capacity. The role of beneficial bacteria, however, is the degradation of nutrients in the medium and the degradation of food into chelated proteins of smaller size.

Seaweed is an excellent nutrient for promoting the growth of large roots, as it contains cytokinins and natural growth regulators. Felt growing pots are another great way for roots to breathe and develop. Of course, they will decompose themselves or. open, which will allow the roots to expand and enlarge the root zone.

Adding molasses

We all know how plants use sugar to convert it into energy. Black molasses is a mineral-rich syrup obtained by squeezing sugar cane and is the only sweetener that acts alkaline and does not acidify the body. There are several types of molasses, and the most prized is the darkest, which has a slightly bitter taste. Bright is sweeter, but contains much less vitamins and minerals. The quality depends on the ripeness of the cane and on the extraction method and the amount of sugar obtained. Black molasses is a real treasure trove of nutrients, it contains calcium, iron, magnesium, potassium, manganese, B vitamins, copper and chromium. Beneficial bacteria feed on carbon, which allows them to convert food to the root zone. Adding molasses to the nutrient solution dramatically increases the final weight of the crop.

In the end, no matter if you are a grower indoors or outdoors, you need to consider a number of things. They are all too big to ignore. By maintaining a balanced and organic medium, you will grow your plants in the healthiest and most efficient way. It is advisable to learn about microbiology, or at least delve into it, to understand how soil and plants communicate with each other.
