Plants in an indoor garden tend to grow straight toward the lights, almost in a single file. With a technique known as “low-stress training” you can help your plants become bushier, with more leaves to gather energy from the lights. At the same time, you can dramatically increase the number of flower buds they produce. Low-stress training, often referred to as LST, is simple, requiring no special equipment or skills – even a first-time grower can have success with it. Here’s what you need to know:
Low-Stress Training Creates More Buds
Many growers remove the top tier of foliage before starting LST. While not necessary, cutting or pinching off the uppermost leaf clusters stimulates the plant to begin branching out and it gives you a symmetrical base to start the training.
What to Use with Low-Stress Training
To hold the stem in place, loop the end you’re holding of the twist-tie to the container. If there are no openings or handles on the top edge of your containers to which you can secure the twist-ties, you may need to punch a few holes yourself. Some growers attach ties to fishing weights to hold down the stems, while others anchor them with hooks pushed into the soil. However you decide to tie down your plants, be sure you don’t attach them to something immobile, so that you can still move the containers, if necessary.

Some plant stressors are counterproductive to growth as they inhibit the plants’ ability to absorb light for photosynthesis, constrain appropriate amounts of leaf transpiration, increase susceptibility to pest/disease attack, and potentially cause the plants to develop genetic abnormalities (hermaphroditism); all of which could devastate an entire flower crop.

Because commercial operations require cameras in every room of the grow, look for cameras and other emergency lights that have green indicator lights instead of red and then securely cover the light with a piece of electrical tape.
Bad Stress for Cannabis
There are a variety of good types of stress that can be introduced throughout the growing cycle. Exposing cannabis plants to good stress will result in robust plants that are more likely to produce more resin and larger buds. The best plants are the ones that not only survive doses of good stress, but actually thrive on it. To ensure you are growing the best plants, it is important to cull plants at each stage of growth.
