Abbreviation for High Stress Training. A cannabis cultivation technique where growers deliberately apply physical stress to the plant, such as cutting, bending, or topping, to manipulate its growth pattern and encourage the plant to produce more flower sites and improve overall yields. The idea behind HST is to redirect the plant’s energy from vertical growth toward creating a more even canopy, maximizing light exposure to all parts of the plant and boosting flower production.

HST techniques need recovery time built in. Stress the plant and then let it bounce back before harvest.
