Autoflowering Mix by Royal Queen Seeds
The Autoflowering Mix is a feminized seed sampler from Royal Queen Seeds that lets you grow 3 or 5 different autoflowering strains in a single run — then pick your favourite for the next round. Rather than committing to a full pack of one genetics, you get a side-by-side comparison of RQS' best-selling autos, from seed to harvest in 8-10 weeks flat.
Which Pack Size?
The 3-seed pack contains Royal Kush Automatic, Diesel Automatic, and Quick One — one seed of each. Go for the 5-seed pack and you also get Royal Jack Automatic and Royal Bluematic added to the mix. If you want a proper side-by-side comparison with indica-leaning, sativa-leaning, and hybrid genetics all in one tent, the 5-pack is the one we'd grab.

Complete your setup with a propagation kit to give these seeds the best start. A root stimulator and light, airy soil mix with perlite will keep your autoflower seedlings happy through those critical first two weeks. If you're growing indoors, pair this mix with a 60x60 or 80x80 grow tent — 5 autos fit comfortably in an 80x80 with room to breathe.
Why Grow an Autoflowering Seed Mix?
Autoflowering seeds flower based on age rather than light cycle changes — a trait inherited from Cannabis ruderalis genetics. According to a review in Frontiers in Plant Science (PMC10421669), photoperiod insensitivity in cannabis appears to be governed by specific genetic loci, meaning these plants are genuinely hardwired to flower on their own schedule regardless of how many hours of light they receive. No timer adjustments, no light leaks to worry about, no 12/12 flip.
The practical upside? You can run a full cycle — seed to chop — in 8-10 weeks. That's roughly half the time of a photoperiod grow. According to research published in Genes (PMC7968383), autoflowering cannabis varieties reach maturity in approximately 2-3 months compared to 4-6 months for photoperiod strains. For anyone growing in a short outdoor season or wanting multiple harvests per year indoors, that speed is hard to beat.
Now, the mix format specifically: it solves the "analysis paralysis" problem. We've seen customers spend weeks agonising over which single strain to commit to. With the Autoflowering Mix, you grow 3 or 5 different genetics simultaneously, compare them side by side under identical conditions, and then you know — from actual experience — which one deserves a full pack next time. It's a taste test, not a blind commitment.
What's in the Autoflowering Mix — Strain Breakdown
Each strain in this mix brings something different to the table. Here's what you're working with:
| Strain | Genetics | THC | Cycle | Character |
|---|---|---|---|---|
| Royal Kush Automatic | Sweet Special Auto x Kush | 13% | 8-9 weeks | Spicy, resinous, uplifting daytime smoke |
| Diesel Automatic | Diesel lineage | ~14% | 9-10 weeks | Fuel-forward aroma, energising |
| Quick One | Lowryder-based | ~13% | 8 weeks | Compact, fast, beginner-friendly |
| Royal Jack Automatic (5-pack) | Jack Herer auto | ~16% | 9-10 weeks | Sativa-leaning, cerebral, peppery |
| Royal Bluematic (5-pack) | Blueberry auto | ~14% | 8-9 weeks | Fruity, sweet, relaxing |
Royal Kush Automatic is the standout for resin production — thick, sticky buds with a spicy Kush nose that fills the room when you crack a jar. It grows taller than most autos (120-150cm outdoors), which translates to heavier-than-average yields. At 13% THC, it's a proper all-day smoke — functional without being overwhelming.
Quick One is the speed demon. Based on Lowryder genetics, it's one of the fastest autoflowers you can grow. Compact, discreet, and forgiving of beginner mistakes. Not the biggest yielder, but it finishes before everything else in the tent, which is satisfying in its own right.
The honest limitation here: because this is a mixed pack, you get one seed of each strain. If one doesn't germinate (rare with RQS, but it happens), you've lost that strain from your comparison. Handle germination carefully — we'd recommend the paper towel method or direct sowing into a small pot of moist coco/perlite mix.
How to Grow Autoflowering Seeds from This Mix
- Germinate each seed using the paper towel method: place seeds between two damp (not soaking) sheets of kitchen paper on a plate, cover with another plate, and keep at 20-25°C. Taproots should appear within 24-72 hours.
- Plant each germinated seed directly into its final pot — 11-15 litre fabric pots work well. Autoflowers don't love transplanting because their short lifecycle doesn't give them time to recover from root disturbance.
- Use a light, airy growing medium. A mix of coco coir with 30% perlite is ideal. Autoflowers have a shorter life cycle and benefit from substrates that don't hold too much moisture around young roots.
- Keep your light schedule at 18/6 or 20/4 from start to finish. Unlike photoperiod plants, these don't need a 12/12 switch to flower — they'll begin flowering automatically around week 3-4.
- Go easy on nutrients for the first 2-3 weeks. A good potting mix provides enough food initially. When you do start feeding, use 1/4 to 1/2 the dose recommended for photoperiod plants. Autoflowers are lighter feeders.
- Watch for the first pre-flowers around day 21-28. Once you see pistils forming, transition to a bloom nutrient. Keep doses conservative — overfeeding is the number one mistake we see with autos.
- Harvest when trichomes are mostly cloudy with a few amber ones appearing. Each strain will finish at slightly different times, so check them individually rather than chopping the whole tent at once.
Autoflowering Seeds: Benefits for Indoor and Outdoor Growers
Autoflowering cannabis seeds offer a shorter path from germination to harvest than photoperiod varieties. According to a study on Cannabis tissue culture (PMC7968383), autoflowering varieties reach very early maturity in approximately 1.5-3 months. That compressed timeline opens up possibilities that photoperiod grows simply can't match.
Indoors, you can run 4-5 cycles per year under a fixed 18/6 or 20/4 light schedule. No need for a separate vegetative and flowering room. No light leak paranoia. Outdoors, the short lifecycle means you can start a batch in late spring and harvest before the worst of autumn weather arrives — or run two successive plantings in a single season if your climate allows.
According to research on Cannabis photoperiod responses (PMC10004775), the autoflowering trait likely reflects the geographical origin of Cannabis ruderalis genetics — plants that evolved in northern latitudes with short summers adapted by flowering based on age rather than day length. Modern breeders have crossed that trait into high-potency genetics, giving you the best of both worlds: speed and quality.
The trade-off? Autoflowers generally produce slightly smaller plants than photoperiod varieties given unlimited vegetative time. But in a controlled indoor environment with good light, the difference in final yield per square metre is narrower than most people think — especially with modern genetics like those in this RQS mix.
Frequently Asked Questions
What are autoflowering seeds and why do growers use them?
Autoflowering seeds produce plants that flower based on age (typically 3-4 weeks after germination) rather than changes in light cycle. Growers use them for faster harvests — 8-10 weeks total — and simpler light management. No need to switch to 12/12 lighting to trigger flowering.
What is the best soil for autoflowers?
Light, airy mixes work best. Coco coir with 30% perlite, or a light potting soil with added perlite and vermiculite. Autoflowers have smaller root systems and shorter lifecycles, so heavy, waterlogged soils cause problems. Avoid heavily pre-fertilised mixes that can burn young seedlings.
How much nutrients should I give autoflower plants?
Start with 1/4 to 1/2 the dose recommended for photoperiod plants. No nutrients at all for the first 2-3 weeks if your potting mix is decent. Autoflowers are lighter feeders with less time to recover from overfeeding — less is genuinely more here.
Can I grow different autoflowering strains together in one tent?
Yes — that's exactly what this mix is designed for. The main consideration is that different strains finish at slightly different times (8-10 weeks), so you'll harvest them individually rather than all at once. Height differences are manageable with LST (low-stress training) if one plant stretches more than others.
What light schedule is best for autoflowering cannabis seeds?
Most growers run 18 hours on, 6 hours off (18/6) from seed to harvest. Some push to 20/4 for slightly faster growth. Unlike photoperiod plants, autoflowers don't need a 12/12 switch — they flower regardless of light hours. The extra light simply gives them more energy to produce bigger yields.
How do Royal Queen Seeds autoflowers compare to other seed banks?
RQS has built a strong reputation in European autoflower genetics specifically. Their autos consistently produce denser buds and higher THC than budget alternatives. If you want to compare directly, grow this mix alongside a competitor's auto — the side-by-side will tell you more than any review.
Will all seeds in the Autoflowering Mix germinate?
RQS feminized seeds have a high germination rate — typically above 95%. But no seed bank guarantees 100%. Use proper germination technique (paper towel method at 20-25°C) and plant taproots gently downward. With only one seed per strain in this mix, careful handling matters more than usual.
