Topping and low-stress training (LST) help open the canopy, while SCROG setups can boost yield and uniformity.

Keep temps between 68–78°F (20–25°C); slightly cooler nights can help bring out purple coloration.

Use a balanced vegetative nutrient line early, then transition to bloom-specific nutrients with higher potassium and phosphorus.
