1. Summary
Apollo 13 is a Brothers Grimm hybrid of Genius, a female clone that came from the same Sensi Smile Jack Herer bud as Princess, and a P.75 male. P.75 is the second backcross generation of the Cinderella 99 cubing program. A breeder description dated "circa 1998" gives 45β55 days of flowering.1 MrSoul, quoted by Subcool in 2010, said "The father of Apollo 13 was P.75 whereas Apollo 11's dad is Cinderella 99."2 Relaunch-era Brothers Grimm texts say the same thing.34 A second claim, found only on forums and lineage lists, names a Princess 88 / Cinderella 88 father instead.567 The two claims are recorded as disputed. The original seed run was small: the "only 500 seeds" figure is repeated but no primary source for it was found.8 The line survived in three forms:
- clones, notably Subcool's cutting, which TGA used for Vortex and Apollo 13 BX;8910
- open-pollinated seed lines carried from F1 to F6;11
- a Brothers Grimm recreation made c. 2016β17 by crossing an original Apollo 13 female back to a P75 male grown from stored seed. That version is now discontinued.112
2. Identity
- Names: Apollo 13, A13, Apollo-13, "Apollo13" (SeedFinder spelling). Not the same as TGA's Apollo 13 BX or the Reserva Privada "Apollo 13 (Indica)/(Sativa)" listings.913
- Type as reported: "delicate balance of indica/sativa" (c.1998). SeedFinder's basic info calls it "mostly indica". Growers describe sativa-type and indica-type expressions.11415
- Era: c. 1998 original; recreated c. 2016β17.116
- Breeder: Brothers Grimm Seeds (MrSoul, with Sly).
- Propagation: seed (original regulars, which were scarce) and clone (several elite cuts, e.g. Subcool's cut and a "Puffs cut").817
- Region: USA, from Amsterdam bagseed through the Genius mother.
3. Genetics & lineage claims
3a. Genius Γ P.75 (breeder)
Confidence: verified (breeder statement, quoted). Disputed with 3b. MrSoul (quoted by Subcool, 2010): "Apollo 11 & 13 are from the same mother plant (Genius). The father of Apollo 13 was P.75β¦"2 Relaunch-era BG texts give the same father: "P75 is also the father of Apollo 13"3 and "Apollo 13 (genius x p75)".4 Subcool's 2008 article,8 DNA Genetics' Reserva Privada store (2008, "Genius mother x P75 father")13 and the Mota Rebel F4 line1118 all repeat Genius Γ P75. P.75 = Princess Γ P.50 (a P.50 male backcrossed once to Princess), per the C99 dossier.19
3b. Genius Γ Princess 88 / Cinderella 88
Confidence: reported (forum and lineage lists only) A long-time Overgrow grower wrote in 2018 that MrSoul probably no longer has "the C88 father of Apollo 13".5 A THCFarmer lineage list (seen only as a search snippet) gives "Genius X Princess 88",6 and Strainpedia (snippet only) gives "Genius Γ Princess".7 No breeder text supporting a C88 father was found.
3c. Origin of the mother (Genius)
Confidence: verified that this is the breeder's account. Contested at its root (see princess dossier). MrSoul (quoted 2010): Apollo 13's mother "was bred from a mysterious hybrid of Jack Herer crossed with an unidentified male".2 Genius is a sister of Princess and CafΓ© Girl.19
3d. "Only 500 seeds"
Confidence: folklore Subcool (2008) attributes the figure to "the original information on this Brothers Grimm strain".8 NorStar's copy repeats it.15 No primary BG text containing the figure was found.
4. Timeline
- c. 1998: Apollo 13 description written (45β55 days; 120β150 cm; 400 g/mΒ²).1
- 2008: Subcool writes about his "old and hard to work with" original Apollo-13 cutting, used to make Sputnik, Vortex and The Void.8 DNA Genetics / Reserva Privada lists Apollo 13 (Indica) and (Sativa), both Genius Γ P75.13
- by 2010: TGA offers Apollo 13 BX (Apollo 13 Γ a Vortex male).2920
- 2011β2012: Growers discuss A13 BX and Vortex as the available ways into the line.2114
- 2012β13: Mendel releases an Apollo 13 F4 under the Motarebel label. It came from NorCal growers' F1βF3 greenhouse populations.11
- c. 2016β17: BG recreation (original A13 female Γ P75 male). Packs and freebies appear in shops by May 2017.11622
- 2024: "Even" auctions an open-pollinated F6 line.11
- 2026: Apollo 13 and "A13 Haze" are on BG's discontinued list.12
5. Notable cuts / phenotypes / remakes
- Subcool's cut (TGA): vine-like, needs nutrients, fox-tails when warm, peppery rotting-fruit smell, harvest window day 54β65, famous for red bubble hash.8
- TGA Apollo 13 BX: the Apollo 13 cut Γ a Vortex male, which took 60 plants and a year to select. Mostly sativa, 55β60 days, "rotting fruit, citrus, and baby poo".920
- Vortex (TGA): Apollo 13 Γ Space Queen.10
- Mota Rebel F4 β Even F6: kept through open pollination with no culling. Phenotypes: gorilla-arm (~1/6), pineapple (~1/4), fewer Genius types than in A11, "baby dump" (~1/10).11
- BG recreation (2016β17): original A13 female Γ P75 male. Squat, citrus-mango, 50β60 days.1
- Duke Diamond: "Apollo 13 x SSGH" and "Apollo 13 Puffs Cut x TGA Vortex".17
- X13 (Webfish, Cannabis World era): Airborne G13 Γ Apollo 13.23
6. Historical descriptions by era
- c. 1998 (breeder): "This skunky girl will make your eyes water with her pungent perfume". The high is clear and cerebral "without a hint of paranoia", citrus flavour, 45β55 days.1 MrSoul describes a "Lemon Pledge" citrus scent over acrid skunk, and says A13 is as strong as Cinderella but a more "happy, social high" with no couch-lock.2
- Original-era grower memory: it stretched more than his other BG cut, "but still manageable".24
- 2008β2012: see Β§5. One grower found A13 had more body buzz than A11, with fox-tails and a spicy funk.14
- 2016β2024: recreation at 50β60 days, 4β8 oz per plant.1 F6 line at 55β60 days.11
7. Cannabinoid & terpene profile
Caveat: strain names are not reliable chemotype identifiers. None of these lots can be traced to Brothers Grimm seed or to an original clone.
| Source | THC avg (median) | CBD median | CBG avg | Terpenes | n |
|---|---|---|---|---|---|
| Cannlytics MI/CO/MA flower named "Apollo 13" (2015β2023, 14 producers)25 | 18.3% (19.0%) | 0.02% | 0.58% | myrcene 0.54, caryophyllene 0.38, limonene 0.17 (n=2), Ξ±-pinene 0.10 | 50 (terpenes n=6) |
The maximum values (THC 36.7%, CBD 17.8%) are outliers. A terpene panel of n=6 is too small to define a profile. Growers describe the aroma as lemon and pepper, but myrcene and caryophyllene lead in these panels.
8. Community sentiment
Sample: about 40 forum posts (Rollitup 2008, 2011 and 2012; MarijuanaPassion 2010; Overgrow 2017β2026) and about 15 Reddit post titles. No aggregator ratings were read.
- Grail status and scarcity: common.82111
- Clear, social, less paranoid than C99: common.214
- Lemon / peppery / rotten-fruit funk aroma: common.282627
- Finicky, floppy clone: occasional, negative.8
- Doubt that relaunch versions match the original: occasional.225
- Hash quality: occasional, positive.821
Representative paraphrases:
- MrSoul: A13 and Cindy are equally strong, but A13 is the happier, social one.2
- A TGA A13 BX keeper rated "better than 90%" of high-grade weed.21
- The original A13 was mostly fruity, with an underlying skunk funk from Genius.26
Score: 80/100 (sample small).
9. Open questions / could not verify
- Was the father P.75 (MrSoul as quoted) or P.88/C88 (forum claim)? No 1998β2001 catalog page for Apollo 13 was read.
- The exact release date and seed count. The "500 seeds" figure has no primary source.
- Where Subcool's cut and the "Puffs cut" came from.
- Whether the 2008 Reserva Privada versions were seed lines made from BG stock.
- Seeds Direct 2001 items bg03βbg08 and bg12β16 were not re-fetched (Wayback 429).
