Planting usually begins between March and April and lasts until September or October. About half of all plants started from seed will be male, which are worthless for marijuana. Flowering should begin around July or August, when males can be identified and eliminated.
each seed and strain are different
Sativa plants are generally from 8-14 weeks AFTER VEGETATION
Indica plants are more from 7-10 weeks AFTER VEGETATION
Check with the seedbank you bought from and it should tell you
Remember you have to wait till your plant gets big enough before you switch it to flowering (aka 12 12 light cycle)
When the white hairs are turning rust colored, and the tiny tricromes ( the crystal looking stuff on the buds and leaves) are turning from a milky color to a light amber color it is ready. you will need a magnifying glass to see this best. if left to long it will lose its potency so look for about 10% of the tricromes to turn amber then pick, this is the peek. it can take 6 to 12 weeks for the buds to reach this stage.
6-9 weeks from the beginning of flowering (the start of the 12/12 hour light/dark cycle) for indica or indica dominant strains, 10-18 weeks from the beginning of flowering for sativa or sativa dominant strains.
According to what I read it depends on how long the farmer wants to keep it in the vegetative stage. Usually 2-3 months is the minimum, for growing 3-5 foot plants (unless its pure indica, which is short, but naturally bushy).
There should be no buds longer than 3 inches long. Harvest them before your buds reach this length. You also don't want them to be too dark in color.
Depends the quality of the weed if its good it could take hours if its swag wont take to long.

Once you smoke, it never leaves your system. It might be gone for the most part, but you will always have Weed in your body. It is very, very unhealthy to smoke.
Depending on the THC toxicity of the weed, no more than 2 weeks.
