Appearance

Apollo 13 typically produces long, spear-shaped colas with moderate density. The buds are usually lime to deep green, often exhibiting slight foxtailing. They are generously coated in trichomes, giving them a frosted appearance, and are interspersed with copper or tangerine pistils.

The plant's leaves are slender with narrow leaflets, characteristic of its sativa genetics. Moderate internodal spacing allows for elongated bud development, especially in well-managed canopies.

Aroma & Flavor

The aroma of Apollo 13 is often dominated by terpinolene, presenting notes of fresh pine and lime zest, sometimes with hints of mango. Underlying scents can include subtle skunk and peppery spice, alongside floral or sweet undertones. Grinding the buds intensifies the citrus and pine, while also releasing woody and peppery aromas.

On the inhale, the flavor profile typically starts with lemon-lime and pine notes, transitioning to herbal and floral tastes. Some phenotypes may offer a faint tropical sweetness. The exhale often leaves a lingering peppery spice.

Effects

Apollo 13 is known for its quick onset and uplifting cerebral effects. Users often report a boost in mental clarity and energy, making it suitable for creative endeavors. The experience is generally described as invigorating and clear-headed without significant sedation.

Terpenes & Cannabinoids

Terpinolene is frequently the most abundant terpene in Apollo 13, contributing to its pine and citrus profile. Other common terpenes include myrcene, limonene, caryophyllene, and ocimene, which add complexity to the aroma and potential effects. THC levels are typically reported between 17-25%, with CBD content remaining very low, often below 0.5%.

Origins & Lineage

Bred by Brothers Grimm Seeds, Apollo 13 emerged in the late 1990s as a cross between Genius (a Jack Herer phenotype) and Princess 75. This lineage places it within a family that also includes Cinderella 99 and Apollo 11, all tracing back to the Princess/Genius genetic lines. The strain was developed to combine the rapid onset and uplifting qualities of Genius with the structural stability and yield of Princess 75.

Growing

Apollo 13 is generally considered a sativa-dominant hybrid with a relatively fast flowering period compared to other sativas. Growers often note its manageable stature and the development of elongated, spear-like colas. Phenotypic variability can occur, with some plants leaning more towards the Genius parent's stretch and aroma, while others exhibit a stockier structure.
