About Russian Haze
Crossing a Russian landrace with Haze gives this sativa a lineage that leans toward patience: expect a flowering run of ten to eleven weeks, longer than many modern hybrids, which rewards growers willing to let the plant finish on its own schedule. Flash Seeds lists it at 80 percent sativa to 20 percent indica, and the genetics show in the frame the plant wants to take, especially outdoors where it can stretch to 200-250cm and return 500-600 grams per plant by the end of the season. Kept indoors and trained, it settles into a more manageable 100-150cm while still producing 400-500 g/m2, numbers that put it in solid but not exceptional territory for yield. THC sits between 18.8 and 21.2 percent, respectable rather than extreme. Difficulty is rated moderate, so it isn't a strain for a first-time grower, but anyone with a season or two of experience should be able to manage the height and the long finish it demands.
