About Couch Lock Mixpack Feminised

Read Couch Lock Mixpack backwards from the harvest, with resin filling out towards 26% THC. Weight goes on evenly across bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 49/51 split gives you calyx density and an even spread of resin rather than one at the cost of the other. Outdoors, late September to mid-October is the window that misses the wettest of the finish across most of the country while still letting the caryophyllene arrive.

What's Inside the Couch Lock Mixpack Feminised

The Couch Lock Mixpack Feminised is an assortment of three separate strains rather than a single cultivar, and every pack splits evenly between them. The 3x5=15 option is 5 seeds of each strain, 3x10=30 is 10 of each, 3x15=45 is 15 of each, and 3x20=60 is 20 of each.

  • Granddaddy Purple — a classic indica with deep grape and berry flavours and a heavy body stone.
  • OG Kush — a West Coast legend with earthy pine and sour lemon notes, full-body relaxation and a euphoric head.
  • Strawberry Cheesecake — an indica-leaning hybrid, sweet strawberry over creamy cheese, deeply sedating and suited to the evening.
The specifications listed elsewhere on this page describe the pack as a whole; each strain has its own flowering time, structure and terpene profile.

Getting the weight out of this plant

Three stretches of bloom decide whether you reach the top of this strain's range. 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. Somewhere around a third is typical. One pass of low-stress training over the tallest shoots keeps the top flat.

Weeks three to five. Caryophyllene 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 10-15% amber for the middle of the range. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Rated intermediate difficulty.

What Couch Lock Mixpack is actually like

Growers report sleepy, calm as the defining characteristics and our own notes agree. At 26% THC this hybrid sits where the balance is the selling point. Taken small it stays functional; taken larger it relaxes properly. The ${indica}/${sativa} split means the direction is set by how much you take rather than fixed by the genetics. The Caryophyllene/Myrcene pairing leaves warmth and spice that dries slightly on the exhale.

Best suited to most occasions — the dose does the steering.

Terpene breakdown

Primary: Caryophyllene · Secondary: Myrcene · Tertiary: Humulene. How this profile survives the journey from flower to vapour depends on temperature. Low vaporisation, 180-188°C, keeps the myrcene and humulene audible over the caryophyllene base. Run it hotter, or burn it, and the three collapse into one note — pleasant enough, but none of the complexity that made it worth choosing.

Who it suits

Couch Lock Mixpack 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 the bloom period comfortably for outdoor growers across the country.
