About Cluster Bomb Feminised
Will Cluster Bomb handle a South African summer outdoors? Yes. Put this 79/21 indica in the ground between September and November and you will be cutting from March to May. It stays low enough not to clear a boundary wall, and the short frame carries more weight than its size suggests. Bloom runs 7-9 weeks, placing harvest between March and May across most provinces.
What yield is realistic? 700-795 g/m² indoors is reachable under decent LED with steady feeding. Outdoors, 800 grams a plant is normal in 50 litre pots or straight into prepared ground in full sun. At 20% THC with caryophyllene in front, the return on effort is good.
How much can go wrong before it shows? Some. Anyone who understands pH, a feeding schedule and a light cycle will be fine. Neglect it entirely and it will suffer, but a single missed watering will not undo the grow.
Further Questions from South African Growers
Which medium suits it best? Depends what you are optimising for. Organic soil cut with 30% perlite and amended with bone meal, rock phosphate and kelp meal gives the fuller flavour, and all three are stocked by garden centres, agricultural co-ops and hydro shops countrywide. Coco under automated fertigation at EC 1.4-1.8 through bloom gives the bigger number. This indica genetics performs in either.
Does it cope with real summer heat? Reasonably. The dense foliage shades itself, so a spell above 28°C slows growth without stalling it. Mulch the root zone and water before 7am and heat stress stays manageable through most of the country.
When do I switch to bloom feed? As soon as pistils show, not a fortnight later. The 79/21 genetics changes its demand sharply at the transition: phosphorus and potassium uptake rises while nitrogen demand falls away. Soil growers can top-dress with guano and sulphate of potash; coco and hydro growers should move to a low-N, high-PK formula immediately.
Indoors or outdoors? Indoors buys control over the 7-9 weeks environment. Outdoors, across a September-to-May season, gives you sunlight intensity no LED at any price reproduces, and the full 800 grams. Difficulty: medium. In flower for 7-9 weeks. Stands 90-140 cm. Indoors it returns 700-795 g/m². Outdoors, 800 grams a plant.
Aroma, Flavour and Effect
The first thing Cluster Bomb does at 20% THC is settle a warm peppery spice at the back of the throat. The euphoric, creative, focused, calm effects follow within minutes, starting as weight behind the eyes and working down through the shoulders and limbs. Fifteen minutes in there is a physical stillness — not sedation so much as a disinclination to get up. Two to three hours at a moderate dose. Myrcene sits underneath all of it, adding more body, reinforcing the physical side.
The Aromatic Three
Leading with Caryophyllene, then Myrcene, and Bisabolol underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, caryophyllene leads. After three or four weeks in sealed glass at 16-18°C the bisabolol undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile bisabolol molecules are the first thing you lose.
Suitability and Recommendations
Who does well with Cluster Bomb? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. It is rated medium, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions.
