Cloud Walker Cannabis Seeds by Greenhouse Seeds
Cloud Walker is a feminised cannabis seed from Greenhouse Seeds that pairs Colombian landrace genetics with Californian breeding stock for a tall, colourful, resin-heavy plant. A cross between a select Punto Rojo phenotype — a famous Colombian landrace — and Mendo Breath out of Mendocino, California, this hybrid delivers a distinctive uplifting head effect that transitions into a relaxing body stone. The tropical pineapple, vanilla, and caramel flavour profile is genuinely smooth, the kind of smoke that makes you pause and actually taste it rather than just inhale.
We've carried Greenhouse Seeds since the early days, and Cloud Walker is one of those strains that stands out on paper and then actually delivers in the jar. The Punto Rojo lineage is the star here — Colombian landraces are where cannabis breeding started getting interesting, and that near-psychedelic head character is something you don't find in your average hybrid. If you've grown mostly indica-dominant strains and want something with genuine sativa energy, this is a strong place to start.
Which Pack Size?
Cloud Walker feminised seeds come in three pack sizes: 3, 5, or 10 seeds. If you're running a single tent or a small outdoor patch, the 3-pack gives you enough to select a strong phenotype without overcommitting. The 5-pack is the sweet spot for most growers — enough genetic variation to find a keeper, with a spare or two for a second run. Go for the 10-pack if you're planning a full outdoor season or want to pheno-hunt seriously. Every seed is feminised, so you won't lose half your count to males.

Growing Cloud Walker: What to Expect
Cloud Walker grows tall. That's not a casual observation — she can reach 200cm indoors and will stretch two to three times her vegetative height once you flip to bloom. If you're growing in a 120cm tent, you need to flip early or train aggressively. We'd recommend topping at the fourth or fifth node and running a SCROG net to keep the canopy flat. Without height management, you'll end up with colas pressed against your light, and nobody wants bleached buds after 9 weeks of patience.
The flowering period runs 63–70 days, which is moderate for a strain with this much sativa influence. Outdoors in a temperate European climate, expect to harvest around mid-October. She'll need support — stakes or a trellis — because those densely packed buds get heavy, and the branches are long. The good news: at the end of flower, Cloud Walker puts on a genuine colour show. Purples, deep greens, and orange pistils all over. She's a plant you'll want to photograph before you chop.
Yield potential outdoors is up to 600g per plant, which is serious weight for a sativa-leaning hybrid. Indoors, expect proportionally less depending on your setup, but the resin production is impressive regardless of environment. The trichome coverage on mature buds is thick and visible — this is a strain that looks like it's been dipped in sugar.
Flavour and Effect: The Colombian Landrace Difference
Most modern hybrids taste like some variation of "kush with fruit." Cloud Walker is different. The Punto Rojo genetics bring a tropical pineapple note that's genuinely distinct — not candy-sweet, but fresh and sharp, like cutting into a ripe pineapple. That sits alongside vanilla and caramel undertones from the Mendo Breath side, and the whole thing blends into a smoke that's remarkably smooth. No harshness, no coughing fits. Just flavour.
The effect profile is where the Colombian lineage really shows. Cloud Walker starts with an uplifting head effect that builds quickly — a few draws and you'll notice it. The initial onset is cerebral, energetic, and at higher doses can feel genuinely intense in its clarity. After some time, that head effect settles into a relaxing body stone that takes the edge off without putting you on the sofa. It's a morning-to-afternoon strain, the kind of thing that pairs well with a walk, a creative project, or just sitting in the sun doing absolutely nothing productive.
One honest note: the stretch is the main challenge with this strain. If you don't plan for it, she'll outgrow your space. We've seen growers underestimate sativa stretch before, and it always ends the same way — a frantic late-veg supercrop and a prayer. Plan your flip timing, and you'll be rewarded with one of the more interesting flavour and effect combinations we've seen from Greenhouse Seeds.
How Cloud Walker Compares
If you're looking at Cloud Walker, you're probably also considering other sativa-leaning strains from Greenhouse Seeds or similar seed banks. Compared to a classic like Super Silver Haze, Cloud Walker offers a more varied flavour — that pineapple-vanilla-caramel combination is more complex than the spicy-citrus profile of SSH. The flowering time is comparable (63–70 days vs. 63–70 for SSH), but Cloud Walker's stretch is more aggressive. Against something like Amnesia Haze, Cloud Walker finishes faster and is generally easier to manage in terms of feeding sensitivity. The Colombian landrace genetics also give her a character that feels less "Dutch coffeeshop" and more "something you haven't tried before."
| Trait | Cloud Walker | Typical Sativa Hybrid |
|---|---|---|
| Flowering Time | 63–70 days | 65–80 days |
| Stretch | 2–3x (aggressive) | 1.5–2x (moderate) |
| Outdoor Yield | Up to 600g/plant | 400–500g/plant |
| Flavour | Pineapple, vanilla, caramel | Citrus, haze, spice |
| Colour Display | Strong purples and greens | Varies |
| Landrace Genetics | Yes (Colombian Punto Rojo) | Rarely |
Running Cloud Walker indoors? A SCROG net and adjustable plant stakes are worth picking up — she'll stretch hard during bloom and those dense buds need support. If you're growing outdoors, a quality pair of trimming scissors will save you time at harvest when you're processing 600g of resinous bud per plant.
How to Grow Cloud Walker Cannabis Seeds
- Germinate your Cloud Walker feminised seeds using the paper towel method or directly in a starter plug. Keep the environment warm (22–25°C) and moist. Taproots typically emerge within 24–72 hours.
- Transplant seedlings into their final container once they've developed 2–3 sets of true leaves. Use a well-draining medium — coco-perlite or a light organic soil mix both work well with this strain.
- During vegetative growth, top the plant at the fourth or fifth node to encourage lateral branching. Cloud Walker stretches 2–3x during bloom, so keep veg height under control if you're growing indoors. A SCROG net set at roughly 40cm above the pot rim helps distribute the canopy evenly.
- Flip to 12/12 when the plant reaches about one-third of your available vertical space. She'll fill the rest during the stretch phase. Expect vigorous upward growth in the first 2–3 weeks of bloom.
- Support branches with stakes or a trellis from mid-flower onward. The buds pack on density and resin quickly, and unsupported branches will lean or snap.
- Harvest at 63–70 days of flowering (indoors) or mid-October (outdoors). Look for mostly cloudy trichomes with a few amber heads for the best balance of head and body effect. Dry slowly in a dark room at 18–20°C and 55–60% humidity for 10–14 days, then cure in glass jars for at least 2 weeks.
Frequently Asked Questions
Is Cloud Walker sativa or indica?
Cloud Walker is a hybrid with strong sativa-dominant character, thanks to her Punto Rojo Colombian landrace mother. The Mendo Breath father adds some indica-side body relaxation, but the overall growth pattern, stretch, and head-focused onset are distinctly sativa-leaning.
How tall does Cloud Walker grow indoors?
She can reach up to 200cm and stretches 2–3 times her vegetative height during bloom. If you're growing in a standard 200cm tent, flip to flower when she's no taller than 60–70cm, or use training techniques like topping and SCROG to manage height.
What does Cloud Walker taste like?
The flavour profile combines tropical pineapple with vanilla and caramel undertones. It's a smooth smoke with no harshness — the pineapple note is fresh rather than candy-like, and the caramel comes through on the exhale.
How long does Cloud Walker take to flower?
Flowering takes 63–70 days indoors. Outdoors in a European climate, expect to harvest around mid-October. The relatively moderate flowering time is impressive given her sativa-heavy genetics — many comparable strains need 75–85 days.
What yield can I expect from Cloud Walker outdoors?
Greenhouse Seeds lists outdoor yields of up to 600g per plant, which is achievable in a warm climate with a long growing season. In northern Europe, yields may be somewhat lower depending on sunlight hours and autumn weather. Support branches from mid-flower to handle the weight.
Does Cloud Walker need support during flowering?
Yes. The combination of tall growth, long branches, and dense resinous buds means she'll lean and potentially snap without stakes or a trellis. Start supporting from around week 4–5 of bloom when bud weight starts building.
