About Knockout Og

Knockout Og delivers dense, resin-coated buds and a strong physical high that suits evening use. The genetics combine OG Kush x Northern Lights to produce compact growth, heavy trichome production and a flavour leaning toward pine, citrus and fuel. In a greenhouse this variety rewards attentive environmental control with generous yields and consistent potency. Growers in damp coastal regions should focus on airflow and humidity control to protect flowers during late bloom.

Grow Difficulty:

Grow difficulty is moderate and benefits from hands-on attention to environment and training. In a damp coastal climate you must manage humidity and maintain strong airflow to prevent mould.

Flowering Time:

Indoor flowering completes in about eight to ten weeks. Outdoor timing follows a similar window depending on local season and light.

Yield:

Yield potential is medium to high when plants receive consistent feeding and canopy management. A controlled greenhouse often improves final harvest weight.

Height:

Plants reach a medium to tall stature with a strong central cola and side branching. They respond well to topping and low-stress training to control vertical growth.

Environment:

Indoors Knockout Og performs reliably in a greenhouse or controlled tent environment. Outdoors it flowers well in Edinburgh where summers are short but generally mild.

Climate:

Growing Knockout Og in Edinburgh requires vigilance against mould because of the damp coastal climate. Use raised benches, dehumidifiers and robust ventilation in a greenhouse to keep buds dry and healthy.
