About White Dwarf

White Dwarf is a compact indica-dominant hybrid selected for small spaces and reliable resin. It carries THC in the high teens to low twenties and offers a sedative, relaxing effect suitable for evening use. The plant stays very short and branches densely, making it a good choice for tents, low ceilings and SCROG setups. In Perthshire growers commonly run controlled indoor rooms to manage the cool, wet conditions and reduce mould risk. With seven to nine weeks’ flowering and steady environmental control, White Dwarf delivers medium yields and potent, aromatic flowers.

Grow Difficulty:

Growing White Dwarf is moderately demanding under humid indoor grow rooms because of mould risk. Good airflow and regular inspection cut the biggest risks.

Flowering Time:

Flowering usually completes within seven to nine weeks. Some phenotypes finish closer to the seven-week mark.

Yield:

Yields are medium for a compact plant, often around 400 to 450 grams per square metre indoors. Outdoor harvests tend to be smaller where summers are cool.

Height:

Plants remain very short and bushy, commonly between 40 and 70 centimetres tall. The compact frame suits low-ceiling tents and SCROG methods.

Environment:

Indoors this strain thrives under controlled lighting and ventilation in Perthshire. Outdoors in Perthshire it performs acceptably only in sheltered, sunny microclimates.

Climate:

In Perthshire growers prefer indoor cultivation to manage the cool, damp season and control humidity in humid indoor grow rooms. The strain responds well to dehumidification and steady temperatures when cultivated in Perthshire.
