Howdy Cc420, I do not know because of several factors; first, I do not know how old the plant s are or how long they have been in flower, secondly, the environment of the growing space (wattage and type of lighting, etc.), thirdly the time required to mature varies from strain to strain and plant to plant (within a given strain).
With my setup (220 watts of CFL lamps at 5000°K and 2700°K (mixed 50/50)) my grows have varied from 21 weeks to 28 weeks. I have only grown from some old 'bag seed' that I had saved over the years, so I do not have any direct experience with any of the newer strains. The best thing that I can tell You is to watch the condition (clear, cloudy, or amber) of the tricomes to determine when to harvest. If You want the most THC (as much as the genetics will allow) then harvest when all of the tricomes are completely cloudy. If You want a more relaxing effect, let them go until some of the tricomes turn amber. I prefer mine at around 20% amber.
