Royal Highness

Royal Highness Cannabis Seeds by Royal Queen Seeds

Royal Highness is a CBD-rich feminised cannabis seed from Royal Queen Seeds, bred specifically for growers who want medicinal-grade buds without the heavy sedation. A cross between Respect and Dancehall — both renowned CBD cultivars — this slight sativa-dominant hybrid delivers a clear, functional effect alongside generous yields. If you've been searching for a strain that won't glue you to the sofa, this one belongs on your shortlist.

Why Royal Highness CBD Seeds Stand Out

Most cannabis strains lean hard into THC, which is fine if that's what you're after. But if you want a balanced cannabinoid profile — meaningful CBD content alongside moderate THC — your options narrow quickly. Royal Highness was designed to fill that gap. The parent genetics tell the story: Respect brings the high CBD and sativa structure, while Dancehall reinforces the CBD content and adds a manageable flowering time of just 8 to 9 weeks.

The result is a plant that produces approximately 425 to 475g of dried bud per plant outdoors — a yield that puts it comfortably above average for a CBD-focused strain. We've seen a lot of CBD varieties come through over the years, and the common complaint is always the same: low yields, boring terpene profiles, or both. Royal Highness sidesteps those issues. The buds carry a sweet, fruity aroma with unmistakable skunk undertones — proper dank, not the bland grassiness you sometimes get from medicinal-leaning genetics.

The smoke itself is full-bodied and smooth. No harshness, no coughing fit. The effect is clear-headed and active — you can skin up and still get your to-do list done. That combination of CBD and THC working together is what makes this strain genuinely useful rather than just novel. According to a systematic review published by the National Academies of Sciences, Engineering, and Medicine (2017), there is evidence that cannabinoids, particularly CBD and THC in combination, may be effective for the treatment of chronic pain in adults (NCBI NBK425767). That's the kind of research that gives strains like Royal Highness their credibility.

Genetics and Growing Royal Highness Feminised Seeds

Royal Highness is a feminised seed, meaning every plant you grow will be female — no need to watch for males and cull them mid-cycle. The genetics lean slightly sativa-dominant, but the plant doesn't grow like a typical sativa. You won't be dealing with an unruly 2-metre monster stretching into your lights. The Dancehall parentage keeps the structure manageable, and the 8 to 9 week flowering period is closer to what you'd expect from an indica-leaning hybrid.

This is genuinely a good strain for newer growers. She's forgiving of minor mistakes — slightly off pH, a missed feed, a temperature swing overnight — without punishing you with hermaphrodites or stunted growth. That said, if you're running an indoor setup, keep your humidity below 50% during late flower. Those dense, resinous buds can hold moisture, and mould is the one thing that'll ruin an otherwise perfect run.

Aroma, Flavour, and the Royal Highness Effect

Crack open a cured bud of Royal Highness and the first thing that hits you is the sweetness — ripe fruit, almost tropical, with a sticky-resinous quality that clings to your fingers. Underneath that top note sits a musky skunk base that gives it depth. It smells like proper cannabis, not like a fruit bowl someone left near a grow tent.

The smoke mirrors the nose. Sweet and smooth on the inhale, full-bodied on the exhale, with none of the throat-scraping harshness you get from poorly flushed buds. The effect comes on gently — no sudden rush, no racing thoughts. You'll notice a sense of physical ease settling in while your head stays sharp. It's the kind of effect where you could sit down and read a book, have a conversation, or get some actual work done. The combination of CBD and THC appears to modulate each other, which is consistent with what researchers call the entourage effect — the idea that cannabinoids work better in concert than in isolation.

One honest limitation: if you're chasing a heavy, couch-lock sensation, Royal Highness won't deliver that. She's not built for it. This is a daytime strain, a functional strain. If you want something that hits harder on the THC side, look at something like Royal Gorilla from the same seed bank. But if you want to stay sharp and still enjoy a smoke, Royal Highness is one of the best CBD-rich strains we've come across.

Who Should Grow Royal Highness Seeds

This strain was bred with medicinal users in mind, and it shows. The balanced CBD-to-THC ratio means you get the reported therapeutic properties of both cannabinoids without being overwhelmed by either. According to the National Academies review (2017), there is substantial evidence that cannabis is an effective treatment for chronic pain in adults, and that oral cannabinoids are effective antiemetics in the treatment of chemotherapy-induced nausea (NCBI NBK425767). Royal Highness, with its high CBD content, fits squarely into that medicinal category.

But here's the thing — you don't need a medical reason to grow this strain. If you're a recreational smoker who wants to cut back on THC without giving up the ritual entirely, Royal Highness is a smart rotation strain. Smoke it during the week when you need to function, save your heavier strains for the weekend. We've had customers tell us this approach completely changed their relationship with cannabis — less tolerance buildup, better sleep patterns, and they actually enjoy their high-THC strains more when they do reach for them.

Traditionally, CBD-rich cannabis has been used for easing bodily tension, supporting relaxation, and managing everyday stress. The strain's terpene profile — those sweet, fruity, skunky notes — suggests a mix of myrcene, limonene, and caryophyllene, which are themselves the subject of ongoing research into their potential synergistic effects with cannabinoids.

How to Grow Royal Highness Cannabis Seeds

1. Germinate your seeds using the paper towel method: place seeds between two damp paper towels on a plate, cover with a second plate, and keep in a warm spot (20–25°C). Taproots typically appear within 24–72 hours.
2. Transfer germinated seeds to small pots (0.5L) filled with light, airy soil or coco coir. Plant the seed 1–2cm deep with the taproot pointing down. Keep the medium moist but not waterlogged.
3. Once seedlings have developed 3–4 sets of true leaves, transplant to their final containers — 11L pots for indoor grows, 20L+ for outdoor. Royal Highness responds well to both soil and hydroponic setups.
4. During vegetative growth, maintain 18 hours of light and 6 hours of darkness. Feed with a balanced nitrogen-rich nutrient at half the manufacturer's recommended strength for the first two weeks, then increase gradually.
5. Switch to a 12/12 light cycle to trigger flowering. Expect the transition to take about a week before you see the first pistils. Reduce nitrogen and increase phosphorus and potassium in your feed schedule.
6. Monitor humidity closely during weeks 5–9 of flower. Keep it below 50% to prevent mould in those dense bud sites. A small oscillating fan pointed at the canopy makes a real difference.
7. Harvest when 70–80% of trichomes have turned milky with a few amber ones appearing. For a CBD-rich strain like Royal Highness, harvesting slightly earlier (more milky, fewer amber trichomes) tends to preserve a higher CBD-to-THC ratio.
8. Dry your buds in a dark room at 18–21°C with 55–60% humidity for 7–10 days, then cure in glass jars for a minimum of 2 weeks. The flavour improves significantly with a 4-week cure.
