What Is Low Stress Training? Cannabis Training
Topping, FIMing, SCROG, SOG… it’s so easy to feel overwhelmed by these cannabis training terms. The good news is it isn’t as hard to do as you think! Here is a crash course on Low Stress Training cannabis.
Low Stress Training
LST involves tying a plant stem down so it grows horizontally, rather than vertically. Used in conjunction with topping, it is a great way to encourage your plants to perform without punishing them with stress.
With the aid of a few soft wire ties (that you’re sure won’t cut the plant), simply tie down the main stem so that it’s parallel to the soil. This helps the side branches receive additional light and airflow. This produces more colas.
Thereafter, you can repeat this procedure for the side branches too, extending the plant canopy wider for huge yields. It’s fine to perform Low Stress Training in either the vegetative or flowering stage.
High Stress Training (HST):
HST is an advanced version of LST. By introducing stress to the plant by actually bending or even breaking a stem, the plant will force energy into the other parts of the plant. Additionally, the damage will create a knuckle.
The plant should keep growing above the bend and will probably prosper. Nevertheless, you have to be very careful to not break the branch all the way off. That will essentially “top” the plant at the break. Try crushing the stem between your fingers before bending. This will crease the stem instead of causing a nasty break.
Most growers implement HST during the vegetative stage. However, some growers perform during flowering.
How To Accomplish Low Stress Training
Training a plant isn’t that difficult, it just takes a little time and patience.
- Grow a plant until it has 3 – 5 sets of leaves. Aim for waiting as long as you can but not so long that the stem becomes woodier and harder to gently bend. If you damage the main stem too severely you can kill the plant.
- Pick the tie that will be used: hooks, pipe cleaners, bread ties, string, etc. Ideally, choose something you can adjust as the plant grows.
- Plan how to tie the plant. Again, hooks can secure the plant into the ground. Alternately, the plant could be tied down onto the pot.
- Gently tie the plant around the last internode – the region between the last and second to last set of leaves.
- The top part of the plant which was just bent will bend back up towards the light. This may take as long as an entire day or as few as 3 hours.
- Continue waiting. Tying shouldn’t be done until a new leaf set has formed. New branches will start forming at the sides of the plant, as a lot more light is getting to the main stem.
- When new leaf sets start forming, you can repeat step 4 until you’re out of room in and around the container.
- By this time there should be enough new growth to let you bend the stem horizontally around the interior of the container. Secure with soft ties or metal hooks.
- Repeat #7 & #8 as growth continues and side branches continue to form and reach up towards the light.
- Wait for the plant to flower. It’s probably about time to turn the plants over to a 12/12 light cycle to promote flowering.
Some growers choose to turn the lights off 2 days that are full before harvest. Starving the plant of light prompts it to release all of the resin into the buds that have formed. At harvest time, these buds will be covered in beautiful crystal!
