Two strains with entirely different lineages carry the name Burmese Kush. As a rule, the name refers to the cross by the Dutch breeder TH Seeds, who crossed an indica from Burma of unknown ancestry with OG Kush; in Amsterdam the short form Buku is in common use. Kera Seeds lists a cross of Trainwreck and White Widow under the same name. According to several strain descriptions, High Times added the TH Seeds version to its top 10 list of strains in 2007.
Genetics and Origin:
There is no agreement on the OG Kush side. In the description attributed to TH Seeds, the second parent is simply called OG Kush, whereas US producers state SFV OG Kush in some cases and Burmese Kush x OG Kush in others. The indica share is also quantified inconsistently; strain descriptions give 50, 60 or 70 %.
The strain appears as a parent in crosses by other breeders: Cabin Fever combined it with Loompas Headband for Burmese Headband, Sagemasta Select used it with Mesa Cookies for Desert Python, and ADKGrass's Burma Glue contains Buku together with Sour Glue.
Versions from Different Breeders:
For the TH Seeds version, the description attributed to the breeder states 9 weeks of flowering, a height of 100 cm and more than 400 g/m². Other strain descriptions deviate from this: one from 2012 speaks of 7 weeks, another of about 53 days, a third of 7 to 8 weeks at 600 to 700 g/m². Regular as well as feminized seeds are documented.
Kera Seeds describes its Burmese Kush as 90 % sativa and lists it only as feminized. The breeder gives around 9 weeks of flowering, 350 to 400 g/m² indoors at 55 to 65 cm in height, 115 to 165 g per plant outdoors at 90 to 140 cm, and an October harvest; it puts the THC content at 20 %. Royal King Seeds also lists an autoflowering Burmese Kush with 55 to 65 days of flowering and, by its own account, 15 % THC, without naming its parent lines.
THC and CBD Content:
For the TH Seeds line, the values vary widely. Strain descriptions give 13 to 25 % THC; one of them puts the CBD content at 0.01 to 0.18 %, another additionally lists 1 % CBG. Consumers report batches with 23 to 27 % THC without naming the underlying analysis.
Aroma and Flavor:
TH Seeds describes the flavor as earthy and woody with pine and citrus. US producers add turpentine, cinnamon, cocoa and spice, and another mentions honey and sage alongside a pine-like scent. Grow reports mention hashish, sandalwood and a musky note. Consumers describe a broader spectrum, from grapefruit and sour citrus through fruity and peachy notes to a cheesy, pungent undertone with a hint of diesel.
Strain descriptions list caryophyllene, myrcene and limonene as the dominant terpenes. US producers, by contrast, put terpinolene first in their information, followed by caryophyllene and limonene or by myrcene and caryophyllene; one user report also mentions a batch rich in terpinolene.
Effects:
Relaxation, euphoria and an uplifted mood form the core of the user reports. Several consumers describe a delayed onset, after which the effect gradually builds. How strongly the body is involved is perceived differently: some reports describe a focused or creative state with a mildly activating side, others a heavy physical effect extending to drowsiness and couch lock. Some consumers found the strain weak, and one mentions a short duration of effect. Reported side effects are dry mouth and dry eyes, in isolated cases a mild headache; one strain description also mentions rarely occurring paranoia and dizziness.
Cultivation:
TH Seeds emphasizes the low amount of leaf on the flowers and designates the strain for small grow spaces; a strain description from 2012 derives from this a low trimming effort. Another warns of mold and powdery mildew in warm, humid weather, a third of hesitant growth in the first weeks.
Grow reports paint an inconsistent picture. In one indoor grow, the plant grew bushy and vigorous, stretched from about 15 to 80 cm after the switch to flowering, tolerated topping of the main shoot and formed hard, compact buds after 60 days of flowering; the seeds germinated with difficulty because of their hard shell. In the documented grow by an LED manufacturer with topped plants, 1090 g of dry weight came from a 3 × 3 ft tent after 68 days of flowering.
Outdoors, a plant in Florida in a pool area enclosed by a lattice grew in a fir-tree shape, required nitrogen until the last weeks and was harvested in mid-July after around 48 days of flowering. Another grower reports branches that became so weak in late flowering that they broke in rain, and a disappointingly small yield.
