Two great questions. The answer is going to vary a little based on strain/grower. In general, though, you want to start flushing when you reach 15/20 percent amber trichomes. A week flush before you finish is standard but we go two. Flushing your plants every week to two weeks during their lifespan doesn't hurt either.

Are you doing soil or hydro?
