In other words, the areas that get more light grow more. Most flowers are at the top and the lower parts of the plant don’t get too much light. Since the lower parts are light-deficient, they obviously produce fewer flowers. LST attempts to rectify this problem. The basic premise of this technique is to help the plants get more light.
If the plant starts producing preflowers, avoid topping because the window to train the plant has passed by already. So, try to top the plant within the first 20 days so that the plant has enough time to recuperate and produce healthy, fascinating flowers.
Basically, you’re stressing the plant to produce more, and they will comply. It’s very critical to know when to top, though. For instance, photoperiod plants are topped in their vegetative stage when the plant is still growing. Similarly, autoflowers need to be topped when they are in their growing stage.
FIM stands for Fuck, I Missed, and this method originated when a grower who attempted to top his plants failed miserably. He failed to cut the tip of the plant entirely but was successful with FIMming. He let the plant grow as usual but was surprised when the plant developed several colas instead of two as he had originally planned.
LST is nothing but Low-Stress With this method, you’re stressing the plants very minimally to induce more buds. It also helps if you have plants like Pineapple Express that tend to grow very tall. In a way, you’re not only making the plant yield more, but you’re also reducing the vertical space.
Unlike LST, Topping is actually a High-Stress Training technique. It induces a little more stress than LST and that’s perhaps why growers avoid it entirely. However, topping produces more buds than you can imagine. When you cut off the tip, the lower parts of the plant get more light. When the leaves get more light, they produce more buds and your yields increase automatically.
You can also top the remaining colas to make sure that the plant produces more. When cannabis plants grow normally, they produce a few colas. But when you cut off the tip, the colas multiply and you end up with more buds.
LST is better than other techniques because it doesn’t stress the plant too much. With autoflowers, it’s a good idea to train less since you might stunt the plant if you overdo anything. Since autoflowers have a preset cycle, it may not have a lot of time to recover if you stress them a lot. So, take fewer risks and stick to the plan.

Many cannabis growers hesitate to train their autoflowering cannabis plants. This is because they worry about stunted growth. Typically, an autoflowering plant
