RS11 x Banana OG Cannabis Seeds
RS11 x Banana OG is an indica-dominant hybrid seed from a joint breeding project between Barney's Farm and Doja Exclusive, combining elite genetics for 25–31% THC and yields up to 1500 g/plant outdoors. This is next-generation cannabis breeding — two heavyweight names pooling their best stock into a single seed. If you've grown Barney's Farm strains before, you know the structural quality. Doja Exclusive brings the Californian flavour genetics. The result is a plant that grows like a tank and smokes like dessert.
Choose Your Pack Size
RS11 x Banana OG seeds come in two pack sizes. The 3-seed pack (SKU: CSBF0214) works if you want to run a single pheno hunt or fill a small tent. The 5-seed pack (SKU: CSBF0215) gives you room to select the best phenotype and still keep a mother — we'd go with the 5-pack every time, because having two extra seeds means you can afford to lose one to a germination hiccup without scrambling.
RS11 x Banana OG Terpene Profile and Flavour
The terpene profile on RS11 x Banana OG is layered and genuinely complex — not just "fruity" the way half the seed catalogue claims to be. On the nose, you get zesty lemon hitting first, followed by a warm spice note that sits somewhere between cinnamon and clove. There's a subtle cherry sweetness underneath that rounds the whole thing out. When you actually smoke or vape it, bright grapefruit takes over alongside smooth banana — the kind of creamy, ripe banana flavour that you can actually taste, not just imagine because someone told you it was there.
We've handled a lot of banana-cross strains over the years. Most of them deliver a vaguely sweet, slightly tropical note that you need a vivid imagination to call "banana." RS11 x Banana OG is one of the few where the banana genuinely comes through on exhale. The grapefruit on the inhale keeps it from being cloying. It's a proper two-stage flavour experience.
Growing RS11 x Banana OG Seeds — Indoor and Outdoor
RS11 x Banana OG grows with strong structural integrity, which means she responds well to training techniques like LST, topping, and ScrOG. Indoors, expect plants between 120–150 cm tall — manageable in most tents without extreme height control. Outdoors, she stretches to 150–200 cm, which is substantial but not unruly.
| Specification | Detail |
|---|---|
| Genetics | RS11 x Banana OG (Barney's Farm x Doja Exclusive) |
| Type | Indica-dominant hybrid |
| THC Content | 25–31% |
| Indoor Height | 120–150 cm |
| Outdoor Height | 150–200 cm |
| Indoor Yield | Up to 600 g/m² |
| Outdoor Yield | Up to 1500 g/plant |
| Flowering Time | 65–70 days |
| Outdoor Harvest | Third to fourth week of October |
| Pack Sizes | 3 seeds / 5 seeds |
Indoor growers can pull up to 600 g/m² with proper lighting and feeding. That 65–70 day flowering window is slightly longer than some fast-finishing indicas, but the extra week pays off in density and resin production. Outdoors, the numbers get serious — up to 1500 g/plant in optimal conditions. Harvest falls between the third and fourth week of October, which gives you a decent window before the worst autumn weather rolls in across Northern Europe.
RS11 x Banana OG Indoor vs Outdoor Comparison
Choosing between indoor and outdoor comes down to your setup and what you're optimising for. Here's a side-by-side breakdown of what to expect from RS11 x Banana OG in each environment.
| Factor | Indoor | Outdoor |
|---|---|---|
| Height | 120–150 cm | 150–200 cm |
| Yield | Up to 600 g/m² | Up to 1500 g/plant |
| Flowering Period | 65–70 days from flip | Harvest 3rd–4th week October |
| Training Response | Excellent — LST, topping, ScrOG | Good — topping recommended for bushier growth |
| Best For | Controlled environments, consistent quality | Maximum yield, warm climates |
The honest limitation here: that late-October outdoor harvest means growers in the UK, northern Germany, or Scandinavia are gambling with the weather. If your autumn tends to turn wet and cold by mid-October, you'll want to have a plan for covering or moving plants. Southern European and Mediterranean growers will have a much easier time hitting those 1500 g/plant numbers.
Complete your grow setup with a proper germination kit — the paper towel method works well for RS11 x Banana OG at temperatures between 21°C and 32°C. A humidity dome and seedling heat mat make the first few days far more reliable. If you're growing indoors, pair these seeds with a quality LED panel and a carbon filter — at 25–31% THC, the flower is going to be pungent.
Why RS11 x Banana OG Seeds Deserve a Spot in Your Garden
We've been stocking Barney's Farm seeds since before most online seed shops existed. Their genetics are consistently stable, germination rates are solid, and the plants grow with the kind of structural reliability that makes training straightforward rather than stressful. Adding Doja Exclusive to the mix brings in Californian breeding stock that's been selected specifically for terpene expression and potency — two things that European genetics have historically been weaker on.
The 25–31% THC range puts RS11 x Banana OG firmly in the heavy-hitter category. But what makes this strain interesting isn't just raw potency — it's the effect profile. The effects unfold progressively: deep physical relaxation paired with mental clarity and focus. That combination means you're not locked to the sofa unless you want to be. You can smoke this and still hold a conversation, work on a creative project, or go for a walk. Or you can sink into the couch and let the indica side do its thing. It's versatile in a way that pure sedative strains aren't.
Compared to running straight Banana OG, this cross adds the RS11 genetics which contribute that cherry and grapefruit complexity to the terpene profile. If you've grown Banana OG before and found it a bit one-dimensional on flavour, RS11 x Banana OG is the upgrade. Compared to other Barney's Farm heavy-hitters like Gorilla Zkittlez, this one trades a bit of raw brute force for a more layered flavour and a cleaner headspace.
How to Germinate and Grow RS11 x Banana OG
- Use the paper towel method: place your RS11 x Banana OG seeds between two damp (not soaking) paper towels on a plate. Cover with a second plate and keep at 21–32°C. Check daily — most seeds crack within 24–72 hours.
- Once a white taproot appears (roughly 1–2 cm), transfer the seed root-down into a small pot with light, airy seedling soil or a root plug. Plant about 1 cm deep.
- Keep seedlings under gentle light (18/6 cycle) with humidity around 65–70%. A humidity dome helps enormously in the first week.
- Once the plant has 3–4 nodes, begin training. RS11 x Banana OG responds well to topping and low-stress training. Her strong structural integrity means branches won't snap easily under bending.
- Flip to 12/12 when the canopy fills your space. Flowering takes 65–70 days — don't rush harvest. Check trichomes with a loupe: milky with 10–20% amber is the sweet spot for this strain's balanced effect profile.
- Outdoor growers should transplant to final position after the last frost. Feed heavily during stretch and early flower. Plan your harvest for the third to fourth week of October.
Frequently Asked Questions
What is the THC content of RS11 x Banana OG?
RS11 x Banana OG tests between 25–31% THC. That puts it at the top end of what's commercially available. Expect strong effects even from small amounts — dose accordingly if you have a lower tolerance.
How long does RS11 x Banana OG take to flower?
Flowering time is 65–70 days indoors from the light flip. Outdoors, harvest falls in the third to fourth week of October. The slightly longer flowering period compared to 8-week strains pays off in denser, more resinous buds.
What does RS11 x Banana OG taste like?
Zesty lemon and warm spice on the nose, with a subtle cherry sweetness underneath. When smoked or vaped, bright grapefruit and smooth banana dominate. It's one of the more genuinely complex terpene profiles we've seen from a banana cross.
How much does RS11 x Banana OG yield outdoors?
Up to 1500 g/plant in optimal outdoor conditions. That requires a long, warm growing season, good soil, and proper feeding throughout flower. Northern European growers will likely see lower numbers due to shorter autumns — 800–1000 g/plant is more realistic in the UK or Netherlands.
Is RS11 x Banana OG suitable for beginner growers?
Yes, with a caveat. The plant's strong structure makes training straightforward, and Barney's Farm genetics are known for stability. The 65–70 day flowering window is slightly longer than beginner-friendly fast finishers, so you need patience. Start with the 5-seed pack so you have room for a learning curve.
What training techniques work best for RS11 x Banana OG?
LST, topping, and ScrOG all work well thanks to the plant's strong branching. Indoor growers get the most from ScrOG to maximise that 600 g/m² potential. Outdoor growers should top early to encourage bushier lateral growth and support heavy colas during late flower.
What is the best germination temperature for RS11 x Banana OG seeds?
Between 21°C and 32°C using the paper towel method. Keep the towels damp but not waterlogged. Most seeds crack within 24–72 hours at this range. Transfer to soil root-down as soon as the taproot reaches 1–2 cm.
