Red Tiger
A novelty autoflower strain sold for red foliage, with minimal independent documentation.
Growing, buying or possessing cannabis and seeds is legal only in some places. Check the law where you live before acting on this information.
Red Tiger circulates in small European seedbanks as a visual novelty — it may turn red or magenta during flowering — but has no published breeder record, chemotype data, or widely available lab reports. Any THC, CBD, terpene, lineage or effect claim you read about it is unverified. If you grow or buy it, a certificate of analysis is your only reliable information source.
What we could verify
Red Tiger is sold as a cannabis seed novelty by a small number of European seedbanks. The stated selling point is visual: leaves and bracts that turn red, pink, or magenta during flowering. The red coloration itself is real and reproducible in some plant phenotypes. It is generally attributed to anthocyanin pigments expressed under specific genetic and environmental conditions — cool nights, certain soil pH ranges, and light spectrum can all influence pigment accumulation Strong evidence[1]. This biology is well understood in plants generally.
Beyond that visual trait and the claim that some plants express it, independent documentation stops. There is no published breeder pedigree, no peer-reviewed chemotype study, no widely circulated certificate of analysis (COA), and almost no presence in U.S. dispensary menus or strain databases. No data
What the name suggests — and why that is not evidence
The "Tiger" naming convention has no regulated meaning in cannabis. Multiple distinct plants carry names ending in "Tiger" — Bay Tiger, Queen Tiger, River Tiger — and there is no standardized pedigree, chemotype profile, or even breeder common to them. Strong evidence[2]
Cannabis cultivar names are not protected, genetically verified, or required to correspond to a single genetic source. The same name can refer to genetically distinct plants from different sellers, and breeders are under no obligation to publish lineage, selection criteria, or chemical analysis. Strong evidence[2] This is routine in the industry, not a red flag specific to Red Tiger — but it does mean that any claim about "Red Tiger" genetics, effects, or chemistry without a linked breeder record or lab report is provisional at best.
Marketing copy commonly describes Red Tiger as an autoflowering mild hybrid with earthy or fruity notes. None of these claims has a verifiable source.
What to check if you see it for sale
If you encounter Red Tiger seeds or flower for sale and want to make an informed choice, look for:
- A certificate of analysis (COA) from an accredited lab, tied to a specific batch or harvest date. A Certificate of Analysis (COA) will show THC, CBD, terpene profile, and microbial testing results. Without this, any THC or cannabinoid claim is an estimate, not a measurement. Strong evidence[3]
- A named breeder or seed company with a verifiable website. If the vendor cannot name the breeder or link to one, the provenance is unclear. Ask for selection notes, parent line IDs, or pedigree documentation if lineage matters to you.
- Photos of multiple phenotypes from independent growers. A single vendor photo under ideal conditions tells you nothing about what you will grow. Search cannabis forums or social media for unsponsored grow logs.
- Realistic yield and potency expectations. Vendor-claimed THC levels and yields are not independently verified and often inflated. Strong evidence[3] If a breeder has published lab data alongside their claim, that is more trustworthy; if not, halve the number and adjust expectations downward.
- Clarity on growth habit. Confirm whether this is an autoflower or photoperiod plant. Autoflowers flower on a clock (~8–10 weeks total) regardless of light; photoperiods require a 12/12 light cycle to flower and allow longer veg and training.
Similar documented strains
If you are interested in colorful foliage or mellow autoflowering varieties with more public information available, consider:
- Lunar Sun — documented autoflower with reported purple/blue tones
- Cinnamon Cake — autoflower with reported earthiness and color expression
- River Moon — known for stable phenotypes and published grower reports
- Pure Princess — widely grown autoflower with multiple independent COAs available
These are not necessarily similar in effect or chemistry to Red Tiger; they are simply strains with more public cultivation records and lab data if you want to compare before choosing.
Frequently asked questions
Is Red Tiger indica, sativa, or hybrid?
The question itself reflects a outdated folk taxonomy. The Indica/Sativa Myth explains why this distinction does not reliably predict effects or growth characteristics in modern cannabis. Red Tiger is sold as an autoflower — meaning it flowers based on age, not photoperiod — but "autoflower" and "indica/sativa" refer to different plant traits. Autoflowers are typically small and fast, but that says nothing about whether their effects feel relaxing or energetic, and that feeling varies enormously by individual, dose, tolerance, and context anyway. Strong evidence[4]
How much THC does Red Tiger have?
There is no verified THC level for Red Tiger. Seed vendors often claim 10–15% THC, but these are estimates without lab backing. The only way to know the THC in your batch is to test it with a COA. No data
How long does it take to flower?
Vendor descriptions mention 8–10 weeks from germination to harvest for autoflowers labeled Red Tiger, but this is not independently verified and will vary based on light, temperature, and feeding. Anecdote
Who bred Red Tiger?
