Chow_13answered grow question 3 years ago You cant stop it from growing up, But you can slow it down or even bend it so it is lower.
HST - high stress training.
- "Topping" will slow down the growth as it will have to recover as it starts growing out the lower nodes.
- "Supercropping" bending the branch so it has a sharp bend in it to lower the canopy.
LST - low stress training
-Bending over the branch so it is lower but keeps its stem structure intact.
- SCROG putting a new above the plant and as it grows into it bending it back down so it keeps a flat canopy.
