Picking A Sativa Male

Picking which male to keep in a regular sativa run is harder than choosing a female, because you cannot smoke the result and the plant gives you fewer clues. Stem rub smell, early vigour, tight node spacing relative to siblings and how his sisters behave are the usual criteria. The male selection guide at https://hazesativaseeds.com adds a simple test cross method that only takes one extra plant and a few weeks. Most people keep the biggest male, which is usually a mistake.
