When you talk about legendary sativas from the late 90s, you can't ignore Apollo 13. Originally cracked out of a tiny seed run by the legendary Brothers Grimm, this cut comes from crossing Genius—a very specific, mind-blowing Jack Herer pheno—with their P75 male. The original drop was stupidly limited, maybe 500 seeds total, turning it into a mythical clone-only cut that guys would trade limbs for on old forums. Zenseeds stepped up to rework this classic into regular seed form, and they honestly did the old girl justice. They kept that freaky, vine-like growth structure that demands some serious trellising if you want to support the heavy, resin-soaked colas she pumps out.

But you don't run Apollo 13 just to look at it. You run it for the smoke, and man, it hits like a freight train. The aroma is this absolute funk of sharp, spacey citrus and sour lemon wrapped up in a pungent, skunky pepper that instantly stinks up the whole room. Growers often note that the leaf-to-calyx ratio on the Zenseeds version is fantastic, making trim jail a breeze. She’s a fast finisher for a sativa-dominant plant too, usually wrapping up around 63 days, which is crazy quick for this kind of heady payload.

The high is exactly why old heads still hunt for these genetics. We're talking a clear, euphoric rocket ride that goes straight to the dome. It's the kind of smoke that gets you out of bed, grabbing your tools, and tearing through a project you've been putting off for weeks. If you're looking for that vintage, motivational daytime buzz without the paranoid edge some modern sativas push, Zenseeds' Apollo 13 is a time capsule worth popping.

Growing Apollo 13: what to expect

As a sativa-leaning plant, plan for a big stretch after the flip (often 100–200%) — flip earlier than feels natural and keep training options ready. Sativa-leaning plants also generally prefer a lighter feed than heavy indicas. Growers familiar with Apollo 13 will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
