About Cactus Feminised
The way to plan Cactus is backwards from the day you intend to cut, with up to 200 g/m2 per square metre indoors and up to 300 g/plant per plant outdoors as the figures you are working toward, at 23% THC. Count 55-65 days back from that date and you have your flip date. This one does not dump its weight in a fortnight the way a short indica will; it adds through the whole bloom. Growers who panic about autumn rain and chop a fortnight early routinely hand back a fifth of the crop. Depending on your province the honest window runs from late March into May, and the pinene-led profile only arrives in the last fourteen days.
Where the Weight Actually Comes From
Yield on Cactus — the up to 200 g/m2 indoors and up to 300 g/plant outdoors quoted above — is decided in three short stretches of the 55-65 days bloom rather than evenly across it.
The first ten days after the flip. Whatever stretch happens here sets your canopy, and an uneven canopy wastes light for the remainder of the grow. Stretch runs to 50-60% of pre-flower height. Supercrop anything breaking the canopy line inside the first week or you will be lighting empty air.
Weeks three to five. This is when pinene production climbs, and it answers to the gap between day and night temperature rather than to either number on its own. Keep at least 6-8°C between them. Outdoor growers in the interior provinces get that swing free in March and April; indoors, aim for 25-26°C lights-on against 18-20°C lights-off, with potassium-led bloom feed at EC 1.6-1.8.
The last ten to fourteen days. Stop feeding, flush with pH-corrected water, and read trichomes daily under a 60x loupe. Cut at 5-10% amber, before the clear-headed character starts sliding toward sedation. Outdoors that usually lands between late March and mid-April.
Difficulty: easy. In flower for 55-65 days. Stands Medium. Indoors it returns up to 200 g/m2. Outdoors, up to 300 g/plant a plant.
Aroma, Flavour and Effect
The first thing Cactus does at 23% THC is arrive clean and resinous, like a pine plantation in the mist belt after rain. The creative, happy, relaxed effects follow within minutes, as a sharpening rather than a lift: colour reads more saturated, music holds more detail, conversation wanders further than it would have. It runs two to three hours on a plateau instead of a peak, so nothing drops out from under you at the end. Limonene sits underneath all of it, adding a brightness that offsets any heaviness.
The Aromatic Three
Leading with Pinene, then Limonene, and Caryophyllene underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, pinene leads. After three or four weeks in sealed glass at 16-18°C the caryophyllene 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 caryophyllene molecules are the first thing you lose.
Suitability and Recommendations
Who does well with Cactus? 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 easy, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions.
