How to grow Green Haze
THC 12% 
Flowering 98 - 140 days Taste
Seb's take
A pure sativa built from Colombian, Indian and Thai stock, patient enough to flower for up to twenty weeks and green enough, top to bottom, to justify the name without much effort. Wood and spice over mango on the nose; the high is social, euphoric and energetic — daylight territory. Best suited to warm, coastal climates and growers who don't mind waiting.
Where it comes from
Ace Seeds built Green Haze from pure sativa stock — Colombian, Indian and Thai lines, a classic equatorial pedigree with not a trace of indica in it. That heritage explains everything about the plant: the height, the long flower, the soaring character. The record notes it grows completely green, top to bottom, which the name reflects plainly enough. A landrace-descended purist's sativa, for those with the patience it demands.
Nose & flavour
Wood and spice lead, with a ripe mango sweetness lifting the top — an exotic, incense-adjacent nose typical of the equatorial sativas it descends from. Clean and aromatic rather than pungent. The sort of profile that has grown rare as modern hybrids have crowded the field.
The high
Social, euphoric and energetic — a bright, cerebral, daylight high with no sedation whatsoever, exactly as a pure sativa should give. At 8 to 12% THC it is gentle by modern standards, more about clarity and sociability than force. Uplifting company for the day, and easy to keep pace with.
Growing it
Regular seeds, and a project — flowering runs 98 to 140 days, or fourteen to twenty weeks, with plants growing tall on their sativa heritage. Outdoors she ripens late, into December or January, and wants a warm, coastal climate at latitudes between 20 and 37. The record praises her resistance and vigour, and notes she needs only low levels of nutrients throughout. A greenhouse often helps her finish. No height or yield figures are fixed, so none are claimed. One for the patient.
