Red Devil
A lesser-documented mostly-indica cannabis strain sold by several seed banks, with sparse verified lineage and no strain-specific clinical evidence.
Red Devil is one of those strain names that shows up in multiple seed bank catalogs with slightly different genetics attached to it. There is no peer-reviewed literature on this specific cultivar, no chemovar analysis in published databases we can point you to, and lineage claims trace back to breeder marketing rather than verifiable pedigree records. Treat the reported effects, THC numbers, and terpene claims here as vendor-supplied estimates, not measured facts. If you buy seeds labeled Red Devil, you are trusting the seller's word.
Overview
Red Devil is a strain name that appears in the catalogs of several European seed banks, including Weed Seeds Express and historically other vendors. Beyond seed bank product pages, there is essentially no independent documentation — no peer-reviewed chemovar analysis, no cannabis-industry lab data we can cite, and no coverage in journalism or reference books. That absence is worth stating plainly: most of what circulates online about Red Devil is copy written to sell seeds.
What vendors generally agree on is that it is marketed as an indica-dominant hybrid with a relatively short flowering time and moderate THC. Beyond that, descriptions diverge.
Chemistry: cannabinoids and terpenes
There is no publicly available, third-party lab dataset breaking down Red Devil's cannabinoid or terpene profile No data. Vendor listings typically claim THC in the mid-to-high teens and negligible CBD, which is unremarkable for a modern hybrid.
Any claim about a "dominant terpene" in Red Devil (myrcene, caryophyllene, limonene, etc.) that you see online is almost certainly extrapolated from general indica folklore rather than measured on this cultivar. The broader research on cannabis chemovars shows that terpene profiles vary widely between phenotypes of the same named strain and between grows [1][2]. In other words, even if one Red Devil sample tested high in myrcene, another from a different seed batch or grower might not.
The popular idea that a specific terpene threshold (like "myrcene above 0.5% makes it sedating") predicts effects is not supported by controlled human data Disputed[3].
Reported effects
Vendor and forum descriptions typically call Red Devil relaxing, body-heavy, and useful for evening use — standard indica-hybrid marketing language Anecdote. There are no clinical trials, observational studies, or structured user surveys published on this specific strain.
More broadly, the assumption that "indica" labels reliably predict sedating effects and "sativa" labels predict stimulating effects is not supported by chemical analyses of commercial cannabis; the indica/sativa split has been shown to correlate poorly with actual chemotype Strong evidence[1][4]. Effects depend on dose, individual biology, tolerance, route of administration, and the specific chemovar you actually receive — not the marketing category.
Lineage
Red Devil's lineage is disputed and poorly documented Disputed. Different vendors describe different parent crosses, and no breeder record with verifiable provenance (dated breeding notes, preserved cuts, or lab-confirmed parentage) is publicly available for this name.
This is common in the cannabis seed market: strain names are not trademarked in most jurisdictions, so multiple breeders can and do sell unrelated genetics under the same name. If lineage matters to you — for example, if you are trying to reproduce a specific phenotype — treat any parentage claim on a Red Devil listing as unverified marketing until you see supporting evidence.
Cultivation basics
Based on vendor listings (not independent grow trials), Red Devil is generally described as:
- Flowering time: ~8–9 weeks indoors
- Indoor yield: around 450–500 g/m² under good conditions
- Height: medium, manageable for tent grows
- Difficulty: suitable for beginners with basic environmental control
These figures are ranges reported by sellers and should be read as best-case estimates under skilled cultivation, not guarantees Anecdote. Real-world yield depends heavily on light intensity, medium, training, and phenotype variation within a seed batch. General cannabis cultivation guidance — on light, nutrients, VPD, and IPM — applies here as it does to any hybrid; there is nothing published that suggests Red Devil requires unusual handling.
Marketing vs. reality
The honest summary: Red Devil is a product name, not a well-characterized cultivar. The gap between what is claimed (specific THC percentages, specific effects, specific lineage) and what is actually verifiable (essentially nothing outside seller copy) is large.
This is not unique to Red Devil. A significant portion of named strains on the market share this pattern: repeated vendor descriptions with no underlying chemical, genetic, or clinical data Strong evidence[1][2]. If you are choosing seeds, the practical takeaways are:
- Judge by the seller's reputation and germination guarantees, not the romance of the strain name.
- Expect phenotype variation within any seed batch.
- Treat THC percentages, terpene claims, and effect descriptions as marketing until proven otherwise by a lab test on your actual harvest.
