My plants are 16 weeks now into flowering. They are half and half, sativa/indica. Combined in the strain are ww, ice, and good bag seed. They look healthy and filled out. trics are 80% milky. Last week i cut a sample and let it air dry for 6 days. Its not strong enough. If I cut a peice tomorrow and quick dry would it be stronger? Can a week make much difference in this stage?
