About Heavy Duty Fruity Feminised

Read Heavy Duty Fruity backwards from the harvest: 400-600 g/m2 under lights, Up to 600 gr outdoors, with resin filling out towards 20% THC. Weight goes on evenly across the 8-9 weeks of bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 60/50 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 myrcene arrive.

Getting the weight out of this plant

Three stretches of the 8-9 weeks of bloom decide whether you reach the top of this strain's range (400-600 g/m2 indoors, Up to 600 gr 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. Somewhere around a third is typical. One pass of low-stress training over the tallest shoots keeps the top flat.

Weeks three to five. Myrcene 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.

Flowering: 8-9 weeks. Indoor yield: 400-600 g/m2. Outdoor yield: Up to 600 gr. Plant height: 120-160 cm. Rated intermediate difficulty.

What Heavy Duty Fruity is actually like

Growers report happy, relaxed, uplifted as the defining characteristics and our own notes agree. At 20% 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 Myrcene/Limonene pairing leaves earth and faint sweetness on the palate, with fruit at the end.

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

Terpene breakdown

Primary: Myrcene · Secondary: Limonene · Tertiary: Pinene. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with myrcene; after three or four weeks sealed in glass at 16-18°C the pinene 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 pinene molecules are the first thing heat destroys.

Who it suits

Heavy Duty Fruity 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 8-9 weeks comfortably for outdoor growers across the country.
