Permanent Whitemarker is a feminised hybrid bred by Growers Choice from Permanent Marker BX1 and White Truffle. Its genetic make-up is roughly seventy percent indica and thirty percent sativa, so the plant leans towards the indica side. The stated THC content is 30 percent. Flowering time is around eight weeks. Indoors, plants are expected to reach roughly 100 to 130 centimetres, while outdoor plants can grow considerably taller, to around 160 to 220 centimetres. Quoted yields are 750 grams per square metre indoors and 750 grams per plant outdoors. Seeds are offered in feminised form, which means they are bred to produce female plants. This indica-leaning cross combines two parent lines, making it a choice for growers who want a compact indoor flower with a clear genetic background.
