Successfully cultivating high-quality cannabis isn’t just about light and nutrients—trellis systems play a critical role in supporting your plants and maximizing yields. However, improper use of these systems can lead to major setbacks. Whether you’re using cannabis netting or investing in a full cannabis growing kit, avoiding common pitfalls can make the difference between a strong, healthy canopy and a failed harvest.
Let’s break down the top mistakes growers make with cannabis trellis netting and how to fix them before they impact your grow.
Skipping Trellis Planning Early in the Grow
One of the biggest mistakes new growers make is waiting too long to install trellis netting for cannabis. If the structure isn’t in place before your plants begin to stretch, you risk damaging stems during setup or missing the optimal window to effectively train the canopy. To avoid this, plan your cannabis trellis layout during the early vegetative stage and install the netting before the plants reach it. This allows you to guide their growth properly and ensures a stronger, more manageable canopy.
Using Low-Quality or Improperly Sized Netting
Not all netting is created equal. Using generic or flimsy material can result in broken branches or sagging support, especially in commercial setups.
What to Do Instead? Opt for strong, flexible trellis netting cannabis that can withstand the weight of heavy colas without restricting growth. The correct mesh size ensures better airflow and easier canopy management.
Overcrowding Plants Under a Single Trellis
Trying to support too many plants with one canopy trellis can limit airflow and create mold-prone environments. Overcrowding also reduces light penetration to lower bud sites. Stick to recommended plant spacing and avoid cramming multiple strains into one grid. Use multiple layers of netting if needed for larger operations.
Overcrowding Plants Under a Single Trellis
Installing trellis netting isn’t enough—it requires daily or weekly interaction to guide branches through the grid. Many growers miss this step, letting their plants grow wild. Best Practice: Train branches outward and downward through the net to form a flat, even canopy. This maximizes light exposure across all bud sites.
Choosing the Wrong Strains for a Trellised Grow
Not all strains respond well to trellising. Some indica-heavy plants grow short and bushy, making them difficult to spread evenly through netting.
How to Choose Wisely? Select strains with vertical and lateral growth tendencies. Use data from previous runs to see which strains thrive in a cannabis trellis netting system.
Failing to Monitor the Canopy After Stretch
During the flowering stretch, plants can rapidly outgrow their netting. Neglecting this phase leads to uneven canopies, broken branches, and light inefficiency.
Pro Tip: Add a second layer of trellis netting for cannabis above the first to control stretch. Monitor plant height and adjust as needed throughout the flowering phase.
Overfeeding or Underfeeding Trellised Plants
Once plants are spread through a trellis, signs of nutrient burn or deficiency can be harder to identify quickly.
Avoid This by maintaining a regular nutrient schedule, observing leaf health closely, and using pH-balanced feeding. With trellised plants, consistency is key to avoid hidden stress.
Poor Airflow Around the Trellis
When airflow is blocked beneath a dense canopy, mold and mildew flourish. Trellis netting cannabis systems, when mismanaged, can trap moisture .
Fix the Flow
Trim lower growth and lollipop plants. Position fans beneath and above the canopy. Keeprelative humidity in check, especially during flower.
Final Thoughts
Trellising your cannabis plants doesn’t have to be complicated—but it does require the right tools and knowledge. Avoiding these mistakes can significantly improve your plant structure, yield, and overall grow efficiency.
