Strain Overview

Origin

Alien OG Fem comes from crossing Tahoe OG with Alien Kush. Originally bred in California, it blends the best of old-school Kush lineage with a trippier, more cerebral edge. The result is a West Coast heavyweight that now has fans all over the globe.

Effects & flavours

Expect lift-off. Fast. The high starts behind the eyes and quickly spreads down the spine with a warm, fuzzy blanket of calm while your brain does somersaults. Creative thoughts spark up, stress drops out, and before you know it, you’re grinning at the ceiling like an idiot. flavour-wise? Earthy pine meets sour citrus with a touch of fuel. Classic OG profile, just sharper and louder.

THC & CBD Levels

THC levels are seriously no joke. Alien OG routinely clocks in at 24 percent or higher. This is not one for newbies or lightweights. CBD content is under 1 percent, so the experience is all about the full-on psychoactive ride.

Terpenes

Myrcene, limonene, and caryophyllene dominate here. You’ll notice the citrus right away, followed by that peppery, herbal, deep pine vibe that sticks around your palate long after the exhale. It’s loud and it lingers.

Growing Alien OG Seeds

Grow Difficulty

Moderate. Alien OG Fem isn’t a complete walk in the park, but she’s not going to punish you either. She’s sturdy, holds up well to training, and responds well to topping. The challenge lies in dialing in humidity and airflow late in flower because those buds get dense. mould risk is real if you’re not on top of your environment.

Indoor vs. Outdoor Growing

Alien OG does great indoors if you’ve got solid airflow and lights that can really push those trichomes to the limit. Indoors, plants stay under 63 inch. Outdoors, it performs well in drier, sunnier climates, especially in zones with consistent temperatures around 21 °C. Outdoor plants can stretch up to 79 inch, so give them some room. High humidity areas might be tricky unless you’re consistent with pruning and defoliation.

Flowering Time & Yield

You’re looking at a flowering period of around 8 to 10 weeks. Indoors, yields range between 14.1 oz and 19.4 oz. Outdoors, you can expect up to 21.2 oz per plant when conditions are dialed in. Buds are rock-hard, frosty like a ski slope, and stink in the best way. Carbon filters highly recommended.

Tried my hand at Alien OG this season in my outdoor setup.. Had some issues with humidity causing a bit of mold, but after adjusting my watering schedule, it went back on track..flowered well, and gives a relaxed and euphoric high. I already recommended this to my friends., great buy from WSE.

No major issues, just the usual nutrient tweaks. The best part is the smoke, smooth with a sweet pine flavor. The high is balanced, starting with a bit of a buzz and settling into a relaxed body high. Compared to the Blue Dream I grew last time, Alien OG is way more potent.
