Low-Stress Training is a method of plant manipulation that involves bending stems or branches to reshape and optimize the plant’s canopy. Low-Stress Training, or LST, does not include cutting or topping and is often preferred for auto-flower grows.
I’ve done Low-Stress Training a few times but have always used plant wire to bend and shape the plants. This typically involves drilling holes in the pots or using safety pins through the fabric pots to hook wires and pull the plant’s branches downward.
3D Printed LST Clips
These printable plastic clips can be used over and over again to bend and shape your plants without drilling into your pots and using a bunch of disposable fasteners.
Download 3D Printer STL file
If you have access to a 3D printer you can download the same instructions for the clips I used in my LST video. These clips are 45 degree angle, which seems ideal for most.
I do not take credit for these clips or the design of the STL file. This file is widely distributed on the internet and I do not know who originally created it. Please leave a comment if you can help identify.

No 3D Printer? Local 3D Printers are a thing!
You don’t need your own 3D printer to utilize these clips. Many local libraries have 3D printers available to use with very minimal charges. You can also use a local 3D printing service – even Staples offers affordable 3D printing! Find a nearby 3D printing service.
If you’re looking for LST clips that you can buy instead of printing, these are available on Amazon and have good reviews.
These clips look pretty rad, they’re fully adjustable to a full range of angles. These clips can even be used to make incremental bends on fragile plants!
