About Apollo 13 Feminised

Read Apollo 13 backwards from the harvest: 400 g/m2 under lights, 500 grams outdoors, with resin filling out towards 25% THC. This 5/95 cultivar spreads its weight gain across the whole of bloom instead of front-loading it the way a quick indica does. Cutting early out of nerves about the weather is the most expensive mistake made with plants of this shape. In Britain that means holding through late September and into October depending on your latitude, because the terpinolene-led profile only fills out in the closing fortnight.

Getting the weight out of this plant

Three stretches of the 45-55 days of bloom decide whether you reach the top of this strain's range (400 g/m2 indoors, 500 grams outdoors). The rest is maintenance.

The first ten days of flower. What the plant does during the stretch sets canopy height, and canopy height sets how evenly the light lands. It can add half again its height. Supercrop anything that breaks the line of the canopy inside the first week or you will spend the rest of bloom lighting one branch properly and five badly.

Weeks three to five. Terpinolene production climbs through here, and it responds to a day-night temperature gap of 6-8°C. British autumn nights hand that to outdoor growers for free from September; indoors you have to build it, at roughly 25-26°C lights-on and 18-20°C lights-off. Bloom feed goes potassium-heavy around EC 1.6-1.8.

The last ten to fourteen days. Stop feeding and run pH-corrected water. Check trichomes daily under a 60x loupe — cut at 5-10% amber to keep the clear, lifted character intact. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Flowering: 45-55 days. Indoor yield: 400 g/m2. Outdoor yield: 500 grams. Rated intermediate difficulty.

What Apollo 13 is actually like

Growers report happy, energetic, creative as the defining characteristics and our own notes agree. At 25% THC this sativa sits where most people find a workable window. Vaporised at 175-185°C the first effect is lift and mental energy, suited to work that benefits from it, a long walk, or an afternoon with company. The body stays light throughout, which makes it a genuine daytime option for anyone with a tolerance. The Terpinolene/Limonene pairing leaves a finish that keeps changing across a session.

Best suited to creative work, company, getting outdoors, and daytime use generally.

Terpene breakdown

Primary: Terpinolene · Secondary: Limonene · Tertiary: Ocimene. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with terpinolene; after three or four weeks sealed in glass at 16-18°C the ocimene underneath comes up and the whole thing gains a layer. Vaporising between 180°C and 195°C catches the widest span of them, since the lighter ocimene molecules are the first thing heat destroys.

Who it suits

Apollo 13 suits growers with the basics in place. Understand pH, rough nutrient ratios and light cycles before you commit to it; it asks for competence rather than expertise. Photoperiod genetics leave plant size and harvest date under your control — veg longer for bigger plants, or flip early when space is short. The April to October season accommodates a bloom of 45-55 days comfortably for outdoor growers across the country.
