Amphetamine Seeds
Hard-Hitting Indica Power, Auto-Ready in Under Ten Weeks
Amphetamine autoflower seeds deliver a potent 16% THC indica with indoor yields reaching 550g/m², making this one of the more productive autoflowering indicas available for sale today. The strain carries a mild CBD presence (0.1-0.5%), which gives the effect profile a slightly rounded edge without pushing it into hemp territory. If you want a heavy-yielding, fast-finishing indica that does not require a dedicated veg room, Amphetamine seeds are a straightforward buy.

Amphetamine Seeds: Frequently Asked Questions
What THC level can I expect from Amphetamine seeds?
Amphetamine seeds are verified at 16% THC, which places them in the moderate-to-strong range for an autoflowering indica. This is not a high-THC outlier like a Gorilla Glue Auto or a Wedding Cake Auto pushing 24-26%, but 16% from an autoflower that finishes in 8-10 weeks and yields up to 550g/m² indoors is a solid return. The 0.1-0.5% CBD content is low enough that it will not noticeably dilute the THC-driven effect, but it does add a slight body-softening quality that pure THC-dominant indicas at this percentage sometimes lack.
Is Amphetamine a good strain for beginner growers?
Amphetamine carries a moderate difficulty rating, which means it is not the most forgiving autoflower on the market for a first-time run. Beginners who have never grown an autoflower before would be better served starting with something like Easy Bud or Quick One, both rated easy. That said, moderate difficulty for an autoflower mostly means the plant responds noticeably to environmental stress rather than being fragile. Growers with one or two previous grows under their belt should handle Amphetamine without major issues, particularly given the 8-10 week turnaround that limits the window for things to go wrong.
Is Amphetamine worth the price compared to similar strains?
Amphetamine's 450-550g/m² indoor yield at 16% THC in under ten weeks is competitive with mid-range autoflowers like Auto Northern Lights and Amnesia Auto, which typically sell at similar price points. The main variable that affects value here is the unverified lineage. Strains with documented genetics, like those from Dutch Passion or FastBuds with published parent crosses, give you more predictability across multiple packs. If you are buying Amphetamine seeds for a single run or a small test grow, the price-to-yield ratio is reasonable. For large-scale repeat purchases where phenotype consistency matters, the unknown lineage is a factor worth weighing against strains with a clearer genetic paper trail.
Where can I buy Amphetamine seeds online?
You can buy Amphetamine seeds online through Herbies Seeds and Seed City, both of which carry the autoflower version. Herbies Seeds is generally the stronger option for buyers in North America due to their established discreet shipping routes and germination guarantee, which matters for a moderate-difficulty strain where seed quality directly affects germination rates. Seed City is a solid alternative for UK and European buyers who want flexible pack sizes. Both retailers stock Amphetamine autoflower seeds, so compare current availability and pack options at each before ordering.
