Trellising is a method of providing support and structure to cannabis plants, helping them grow vertically and improving overall plant health. In this article, we'll explore the concept of cannabis trellising, its benefits, and the different types of trellis systems available for cannabis cultivation.

What is Trellising in Cannabis Cultivation?​

Trellising is a horticultural technique that involves using a framework of horizontal and vertical supports to guide and support the growth of plants. In cannabis cultivation, trellises are used to provide structural support, promote air circulation, and maximize light exposure to the plants.

The main goal of trellising is to create a more organized and efficient growing environment, which can lead to higher yields and better-quality buds. By providing support for the plants, trellises help reduce the risk of damage from strong winds, heavy rainfall, and other environmental factors.

Benefits of Trellising in Cannabis Cultivation​

There are several benefits to implementing a trellis system in your cannabis garden:

Improved Light Exposure​

By training cannabis plants to grow vertically, trellising allows for better light exposure across the entire plant canopy. This increased light exposure can lead to more significant growth, increased bud development, and higher yields.

Better Air Circulation​

Trellises help to promote better air circulation around the plants, reducing the risk of mold, mildew, and other moisture-related issues. Improved air circulation also helps to regulate temperature and humidity levels, creating a healthier growing environment for the plants.

Increased Plant Support​

A trellis system offers support for the plants, reducing the risk of branches breaking under the weight of heavy buds. This support ensures that your plants can develop healthier, more robust branches and stems, leading to more significant bud production.

Enhanced Pest Control​

By promoting better air circulation and improving overall plant health, trellising can help to reduce the risk of pest infestations in your cannabis garden. A healthy, well-ventilated plant is less likely to attract pests and more resistant to damage from insects and other pests.

Types of Trellis Systems for Cannabis​

There are several types of trellis systems available for cannabis cultivation, each with its advantages and drawbacks. Some of the most common trellis systems include:

Horizontal Trellis​

A horizontal trellis system consists of a series of horizontal support structures placed at various heights throughout the cannabis garden. This type of trellis is ideal for low-stress training (LST) techniques, which involve gently bending and training the branches to grow along the horizontal supports.

Vertical Trellis​

A vertical trellis system features vertical support structures that allow the cannabis plants to grow upwards, creating a wall of greenery. This type of trellis is perfect for the Screen of Green (SCROG) technique, where plants are trained to grow through a mesh screen and develop a flat, even canopy.

Netting or Mesh Trellis​

A netting or mesh trellis system involves placing a net or mesh structure over the cannabis plants, allowing them to grow through the openings. This type of trellis is ideal for the Sea of Green (SOG) method, where multiple plants are grown in close proximity, creating a dense canopy of buds.


Cannabis trellising is a valuable tool for any cultivator looking to improve plant health, increase yields, and create a more efficient growing environment. By providing support and structure to your plants, trellising can help to optimize light exposure, promote air circulation, and reduce the risk of pest infestations. With several trellis systems available, it's essential to choose the one that best suits your cannabis cultivation needs and preferences.
