hi how long will it be till i harvest my plant its been in flower for about 3 weeks its my frist grow i got it under 200v light can some one help me thanks
Now that we have that out of the way, the question depends upon the strain. It could be anywhere from 8-10 weeks for an indica and 10-12+ weeks for a sativa.
you still have a long way to go. just go to radio shack an buy a $10 microscope and look at the tricomes and when they are about 50% brown 50% cloudy time to pick.
