Spirit Tree

Overview

Spirit Tree is a cannabis strain name that appears occasionally on dispensary menus and informal seed-trading forums, but it has no documented breeder of record, no widely available seed release, and no independent lab certificate of analysis that we could verify. That puts it in the same category as most "boutique" or one-off named cultivars: a name attached to a specific batch of flower, sometimes reused by unrelated growers later.

Unlike well-documented cultivars such as Chemdog or OG Kush, where at least partial pedigrees and chemotype data exist in peer-reviewed literature Strong evidence, Spirit Tree has no such paper trail. Everything below is either genre-level information about cannabis strains or explicitly labeled as vendor folklore.

Chemistry

There is no publicly available certificate of analysis (COA) for Spirit Tree from any recognized cannabis testing lab that we could locate. Any THC, CBD, or terpene numbers you see attached to this name on retail menus reflect a single batch tested for that retailer — not a stable strain-wide chemotype No data.

That caveat matters because peer-reviewed chemotyping work has repeatedly shown that flower sold under the same strain name can vary dramatically in cannabinoid and terpene content between growers, and that many "strains" are not genetically distinct from one another ^[1][2] Strong evidence. Without at least several independent COAs from different grows, no honest chemistry profile can be given for Spirit Tree.

If you have flower labeled Spirit Tree in hand, the COA for that batch is the only chemistry data that applies to it.

Reported effects

We have not found any published user survey, clinical study, or aggregated review dataset specific to Spirit Tree. More broadly, there are essentially no strain-specific randomized clinical trials for any cannabis cultivar — effects research is done on cannabinoids and, occasionally, whole-plant extracts standardized by chemotype, not by strain name ^[3] Strong evidence.

The "indica vs. sativa" shorthand that vendors use to predict effects is not supported by the genetic or chemical evidence; the terms don't reliably map onto how flower actually makes you feel ^[1][4] Strong evidence. So even if a menu labels Spirit Tree as "relaxing indica" or "uplifting sativa," treat that as marketing language, not a prediction.

Lineage

The lineage of Spirit Tree is disputed and undocumented Disputed. Various online strain aggregators list speculative parents, but these sites frequently republish unverified user-submitted pedigrees and have been criticized in peer-reviewed work for propagating inaccurate lineage claims ^[1][2].

Without a named breeder, dated release, or genetic analysis (e.g. via a service like Phylos or Medicinal Genomics), no lineage claim for Spirit Tree can be verified. If you see a confident "Spirit Tree = Strain A × Strain B" claim, ask where that information originated. In most cases the answer is "an anonymous forum post."

Cultivation basics

No breeder grow notes for Spirit Tree are publicly documented. Any flowering time, yield, or difficulty figure would be invented.

In general, for an unverified boutique cultivar you should assume: photoperiod (not autoflower) unless the seller says otherwise; roughly 8–10 weeks of flowering, which covers the vast majority of modern hybrids; and standard indoor practices for hybrid cannabis — moderate feeding, 40–55% RH in flower, and pest scouting for powdery mildew and spider mites [evidence:strong, but genre-level, not strain-specific]. Treat the first run as a data-gathering grow.

Marketing vs. reality

"Spirit Tree" is an evocative name, and evocative names sell flower. That's the honest read on most rare-strain listings: the name does marketing work that the underlying genetics may or may not back up.

A few reality checks worth repeating:

• Strain names are not trademarks in most jurisdictions. Two growers can sell completely unrelated flower under the same name, legally ^[4] Strong evidence.
• Genetic studies have found that many differently named strains are nearly identical, and same-named strains from different sources are often not ^[1][2] Strong evidence.
• The "entourage effect," terpene-based effect prediction, and folklore like the myrcene 0.5% indica threshold are not established science — they're plausible hypotheses at best, and marketing shorthand at worst ^[3][5] Weak / limited.

If Spirit Tree flower in front of you smells great, tests clean, and the COA looks reasonable, enjoy it. Just don't pay a premium for the name alone.
