Santa Marta Haze (Seedstockers)

Santa Marta Haze Cannabis Seeds by Seedstockers

Santa Marta Haze is a sativa-dominant feminised cannabis seed that crosses Amnesia Haze with Colombian Jungle Haze to produce a towering, resin-drenched plant with a 10-week flowering time. Bred by Seedstockers, this cultivar pulls its Colombian lineage straight from the jungle — and you can taste it in every fruity, peppery note the buds throw off. If you want a sativa that actually delivers on yield without making you wait half a year, this is the one we'd point you towards.

Why Santa Marta Haze Seeds Deserve Your Grow Space

We've sold a lot of Haze genetics over the years, and the common complaint is always the same: flowering takes forever, yields are disappointing, or the plant stretches so wildly it becomes unmanageable. Santa Marta Haze sidesteps most of those problems. The Colombian Jungle Haze parent brings vigour and structure that Amnesia Haze alone doesn't have, while Amnesia contributes the resin production and that unmistakable cerebral edge.

The result is a plant that finishes in roughly 10 weeks of flower — fast for a sativa of this calibre. In optimal outdoor conditions with plenty of direct light, expect her to reach 3 to 4 metres. That's not a typo. If you're growing indoors or on a balcony with limited headroom, you'll want to top early and consider low-stress training (LST) or a SCROG net to keep things under control. Left to her own devices outdoors, she'll grow like a small tree and reward you with staggering yields of dense, trichome-coated buds.

One honest limitation: this strain demands vertical space or active management. If your grow tent is 1.5 metres tall and you don't want to train, pick something shorter — Seedstockers' own Northern Lights Auto would be a calmer ride. But if you've got a 2-metre tent, a greenhouse, or an outdoor plot with good sun exposure, Santa Marta Haze will fill every cubic centimetre with bud sites.

Flavour and Aroma Profile of Santa Marta Haze

Crack open a cured jar of Santa Marta Haze and the first thing that hits you is a wave of tropical fruit — mango, papaya, something almost like overripe guava. Underneath that sweetness sits a spicy, peppery backbone that sharpens as you break the buds apart. According to research published by the NIH, beta-caryophyllene is the most available sesquiterpene in cannabis plants and extracts, and it's responsible for that characteristic pepper-spice note you'll find throughout this strain's terpene profile (The Cannabis Terpenes, PMC, NIH).

The smoke (or vapour, if you're running it through a dry herb vaporiser) leans heavily on those fruity top notes on the inhale, with the spice rolling in on the exhale. It's loud. Your carbon filter will earn its keep during the final weeks of flower, because the smell fills a room — and then the hallway, and then the neighbours start asking questions. Plan accordingly.

Growing Santa Marta Haze Seeds: What to Expect

Santa Marta Haze is a feminised photoperiod strain, meaning you'll need to switch your light cycle to 12/12 to trigger flowering. Here's a practical rundown of the grow cycle from seed to harvest.

1. Germinate your seeds using the paper towel method or directly in a propagation plug. Taproots typically emerge within 24 to 72 hours.
2. Transplant seedlings into their first pot (1 to 2 litres) once the first set of true leaves appears. Keep humidity around 65 to 70 percent and temperatures between 22 and 26 degrees Celsius.
3. Veg under 18/6 or 20/4 light for 3 to 5 weeks. This is your window to top and train — we'd recommend topping once above the 5th node, then spreading branches with LST ties or a SCROG net.
4. Flip to 12/12 when the canopy fills roughly 60 to 70 percent of your available space. She'll stretch significantly in the first 2 to 3 weeks of flower, sometimes doubling in height.
5. Support heavy branches from week 6 onwards. The buds get dense and the lateral branches will sag without stakes or a trellis net.
6. Harvest after approximately 10 weeks of flowering. Check trichomes with a jeweller's loupe — mostly cloudy with a few amber heads signals peak potency for a cerebral, energetic effect.

Santa Marta Haze Compared to Other Sativa Seeds

Choosing between sativa-dominant strains can feel like splitting hairs, so here's how Santa Marta Haze stacks up against two other popular options we carry.

If you want the Colombian jungle genetics and don't mind managing a tall plant, Santa Marta Haze is the best sativa seed for growers chasing big yields and complex terpenes. If you'd rather keep things compact, HulkBerry is easier to tame indoors.
