RS11 is an indica-dominant hybrid prized for deep relaxation and euphoric calm, while Permanent Marker is also indica-leaning but leans harder into sedating, full-body effects that many users choose for unwinding at the end of a long day. If you want a balanced, mood-lifting experience that still lets you sink into the couch, RS11 is often the pick. If you want something heavier and more knock-out in character, Permanent Marker tends to be the go-to. Both sit in the upper tier of modern cannabis cultivars, but they serve slightly different crowds.
What Is RS11?
RS11 – short for Rainbow Sherbet #11 – is a cross of Pink Guava and OZK, bred by Doja Exclusive. It sits on the indica-dominant side of the hybrid spectrum, typically testing between 25% and 33% THC with negligible CBD. The terpene profile leans heavily on caryophyllene (peppery, earthy), limonene (bright citrus), and linalool (floral, slightly lavender). Together, those aromatics give the flower a sweet, tropical, almost candy-like scent with a subtle fuel note underneath.
The effects tend to arrive as a wave of euphoria that settles into a warm, relaxed body state. Many users report staying mentally clear enough for conversation early on, with heaviness building over the first hour. It is often chosen for evening stress relief, creative daydreaming, and winding down without fully shutting down.

What Is Permanent Marker?
Permanent Marker is a cross of Biscotti, Jealousy, and Sherb Bx1, popularized by Doja Exclusive and Seed Junky Genetics. Like RS11, it tests high – typically 28% to 35% THC – with very low CBD. The dominant terpenes are myrcene (musky, herbal), caryophyllene, and ocimene (sweet, woody, slightly floral). The aroma is gassy and pungent, with a chemical sharpness that explains the name, undercut by a sweetness reminiscent of candy and earth.
Effects are heavily sedating for most consumers. The head effect arrives quickly – a dense, hazy euphoria – but the body component tends to dominate the experience within 30 to 45 minutes. Many users report that Permanent Marker is difficult to stay active on, making it a cultivar best suited to late-evening or nighttime use. Understanding how terpenes like myrcene and caryophyllene shape the experience is worth exploring further – our guide on THCA and terpenes breaks down exactly how those compounds interact.

Effects Comparison
RS11 tends to open with a noticeable cerebral lift – an optimistic, almost giddy feeling that many users describe as warm rather than wired. Within 20 to 30 minutes, that head effect softens into a full-body relaxation that is comfortable but not necessarily couch-locking. Evidence suggests the limonene in RS11 contributes to its mood-elevating quality, while linalool may add a calming, tension-easing layer on top. The experience typically lasts two to three hours, with a gentle fade rather than an abrupt drop.

Permanent Marker hits differently. The onset is similarly fast, but the euphoria carries more weight to it – less energetic, more enveloping. The high-myrcene profile is widely associated with sedating, body-heavy effects, and most users report that Permanent Marker lives up to that reputation. By the 45-minute mark, physical heaviness typically dominates. Duration is comparable to RS11, but the intensity of sedation is generally rated higher. If you find RS11 still lets you hold a conversation, Permanent Marker may make that feel like more effort than it is worth.
Both strains are high-THC, so new consumers or those with lower tolerance should approach either one carefully. The start-low, go-slow principle applies especially here.
Which Strain Is Better for Sleep?
For sleep, Permanent Marker is the stronger candidate of the two. Its myrcene-heavy terpene profile is often associated with sedation, and many users report that the body-heavy effect makes it easier to stay horizontal and drift off. Evidence suggests that high-myrcene cultivars may support sleep onset more reliably than those dominated by limonene or caryophyllene alone.

RS11 is not a bad nighttime option – its relaxing, mood-lifting effects can quiet a busy mind – but it is less likely to tip you into sleep compared to Permanent Marker. If racing thoughts are the main obstacle, RS11 may actually serve you well. If physical restlessness or difficulty staying asleep is the issue, Permanent Marker’s deeper body sedation is probably the better fit.

Frequently asked questions
Is RS11 stronger than Permanent Marker?
On raw THC numbers, Permanent Marker edges RS11 slightly, with reported averages often landing between 28% and 35% compared to RS11’s 25% to 33%. That said, THC percentage alone does not tell the whole story. Many users report that Permanent Marker feels more intense in terms of sedation and body effect, likely due to its myrcene-dominant terpene profile rather than THC alone.
What are the effects of RS11 vs Permanent Marker?
RS11 tends to produce euphoric, mood-lifting relaxation with a moderate body effect – social and pleasant without being overwhelming. Permanent Marker leans into heavier sedation, with a dense, hazy head effect that quickly transitions into a full-body heaviness. Both are indica-dominant and best suited to evening use, but Permanent Marker is the more sedating of the two.
Which is better for sleep – RS11 or Permanent Marker?
Permanent Marker is generally the better choice for sleep. Its high-myrcene terpene profile is widely associated with sedation, and many users report it is more effective at promoting sleep onset than RS11. RS11 can quiet a racing mind and ease evening tension, but it is less likely to produce the physical heaviness that helps most people fall – and stay – asleep.
What does RS11 taste like compared to Permanent Marker?
RS11 has a sweeter, more tropical profile – think candy fruit, citrus, and a faint gasoline edge. Permanent Marker is sharper and more pungent: gassy, chemical, and earthy, with a sweetness underneath that softens the blow. If you prefer sweet and fruity, RS11 is the easier choice. If you enjoy loud, fuel-forward cultivars, Permanent Marker delivers.
Can you mix RS11 and Permanent Marker?
You can, and some consumers intentionally blend high-THC cultivars to layer terpene profiles and fine-tune effects. Mixing RS11 and Permanent Marker would likely produce a deeply relaxing, euphoric experience with a strong sedating lean – probably best reserved for a night when you have nowhere to be the next morning. Given the potency of both, starting with a small amount of each is strongly advisable.
