London Marker
London Marker is an indica-leaning hybrid from Seed Junky Genetics that crosses London Pound Cake #75 with Permanent Marker. Growing Pains identifies its selected production cut more specifically as London Pound Cake #75 crossed with Permanent Marker Genotype #18. That pairing comes through loud, with sharp marker funk cutting into sweet berries, cream, and heavy gas. Earthy spice and woody depth fill out the aroma, while the flavor swings between ripe berry, nutty dough, and a lingering chemical bite.
People who reach for London Marker often report a euphoric, uplifting head change that eases into a relaxed, creative headspace, which is why many keep it around for evening wind-downs and creative sessions. Reviewers frequently mention a returning appetite, so it's smart to have a snack nearby. Fans of the strain tend to call the experience easygoing rather than heavy, though the effects can shift from one bud to the next. Up close, the flowers are chunky and tight, forest green nugs shot through with purple and wrapped in a sticky coat of trichomes that catches the light.
London Marker is a moderate-difficulty strain, a solid pick for growers with a little experience under their belt. It runs a flowering window of roughly 8–9 weeks and can be raised indoors or outdoors, though it does best in a warm, dry, Mediterranean-style climate. Temperatures in the 68–80°F range keep it comfortable, and it's worth holding humidity on the lower side through flowering to protect those tight, resinous colas. Precise yield and height figures aren't consistently published for this specific cross, so plan for the compact, chunky structure typical of its Seed Junky heritage.
