High Stress Training Methods For Maximized Yields

Mainlining Weed Plants

High stress training or HST in short requires you to break or damage your plants therefor the plants go into shock and could slow the growth for up to a week or more. Although HST training is more stressful on your plants the outcome is usually well worth it. High stress training can be used inside in the grow room our outside in the field and is very popular among cannabis growers worldwide. The main reason for high stress training is to help increase yields and to help get the most out of your grow area.  My favorite HST technique is the topping method. After growing for 10+ years I still continue to top all my plants at least once or twice during the veg stage. Why have 1 top when you can have 8 or 16. 

Low Stress Training VS High Stress Training 

Both high stress training and low stress training are different methods of training your plants with the end goal to maximize and increase yields. The only real difference between the two is Low stress training dose not require you to break or damage the plant in any way your simply bending and manipulating the plant to grow in the direction you wish. High stress training requires you to break or damage the plant and the plant needs to take time to recover. Click here if you want to view all the low stress plant training methods.

Super cropping cannabis is the high stress training technique that involves pinching  the branch with your thumb and index finger and bending the branch over to even out the canopy and allow the light to penetrate the growth below. Super cropper is great to use when you have plants stretching .  An uneven canopy equals lower yields.
