Proven techniques to achieve XXL harvests
.jpg "Proven techniques to achieve XXL harvests")
These high-yield cannabis strains combine robust genetics with proven performance, making them ideal for growers of all experience levels. But to push your yields into XXL territory, it's not enough to choose the right strain; you also need to train and shape your plants smartly.
When growing some of the highest-yielding strains indoors, methods like ScrOG (Screen of Green), LST (Low Stress Training), and topping are staples for maximizing light penetration, flattening the canopy, and encouraging multiple main colas. ScrOG is especially effective in indoor setups, while LST and topping work well both indoors and outdoors to balance vertical growth. For best results, start training during the vegetative stage so plants have time to recover before flowering. Combining these methods with good airflow, nutrition, and pruning will help unlock the full yield potential.
For a deep dive into exactly how and when to apply each technique, check out our full guide on training methods.
