Fatso FAQ
- Is Fatso indica or sativa?
- Fatso is classified as hybrid. Treat that as shorthand rather than a guarantee — terpene profile, dose, and your own chemistry shape the experience more than the indica/sativa label does.
- What is Fatso crossed with?
- Fatso comes from GMO Cookies × Legend OG. Breeders and cultivators can select different phenotypes from the same cross, so two growers' versions of Fatso can smell and test noticeably differently.
- What effects does Fatso have?
- Across community reviews, the effects reported most often for Fatso are relaxed (44%), happy (30%), and euphoric (26%) — the percentage is the share of reviewers who mentioned each one. This is aggregated opinion, not a lab measurement or a medical claim.
- What does Fatso taste like?
- The flavor notes reviewers mention most for Fatso are earthy, diesel, and chemical. Terpenes degrade with heat, light, and age, so a fresher package usually reads closer to that description.
- How strong is Fatso?
- Fatso generally tests around 27.1% THC, but potency swings by cultivator and harvest. Every product at Atrium has a certificate of analysis with the actual figure for that batch.
