Permanent Marker is the kind of strain that leaves a mark, just as the name suggests. Royal Queen Seeds built it in two steps: first Biscotti was crossed with Sherbert BX1, then the strongest keeper from that union was married to Jealousy. The result is a 70% indica / 30% sativa photoperiod with serious potency, dense resin production and a nose that is impossible to ignore.
Each parent brings something specific. Biscotti supplies cookie-jar sweetness and a compact, chunky frame. Sherbert BX1 layers in a creamy, sherbet-shop candy tone and can tint the late-bloom buds with colorful fades. Jealousy finishes the job with Cookies-lineage strength, an extra coat of trichomes and a multi-layered bouquet that keeps developing in the jar after a slow cure.
Indoors, Permanent Marker stays manageable at 3 to 4 feet (90–120 cm) and produces 18 to 19 oz/m² (510–540 g/m²) under strong lighting. Flowering takes 55–65 days (about 8–9.5 weeks), a practical window that lets you fine-tune ripeness, resin and aroma before the chop.
Outdoors she grows to 5 to 6 feet (150–185 cm) and yields 18 to 21 oz/plant (510–595 g/plant), with harvest arriving in October in suitable climates.
Candy, Fuel and a Long-Lasting High
The first pull is all sugary candy sweetness, then a savory herbal layer and a crack of black pepper roll in, and a diesel tail hangs around on the exhale. Snap a cured bud in half and the scent turns sharper still, as gas and spice cut through the sugary surface. It is the kind of contrast that keeps you sniffing the jar long after the session.
With THC up to 28%, Permanent Marker is a heavy hitter. The high opens with a bright, euphoric lift that feels creative and upbeat, a great window for music, art or conversation. As time passes, the indica weight takes over and settles into a deep physical relaxation. It is long-lasting and potent, yet the terpene profile gives it more nuance than a simple stoned finish.
Think of it as sketching a brilliant idea on a whiteboard, then sinking into a beanbag to admire it: inspired first, then fully at ease.
Growing Permanent Marker
Her colas get remarkably dense, so keep fans moving air through the canopy during the last weeks of flowering to stop moisture from building up inside the buds. Light training and moderate defoliation open the canopy, improve light penetration and help the lower bud sites develop evenly. Watch the late-flower colors closely: the Sherbert side can bring attractive fades as temperatures drop.
