Introduction

Terraced fields on a mountain slope in the Western Himalayas.

Cannabis cultivation is the growing of the cannabis plant and the work that turns its crop into products: preparing a field, sowing and tending the crop, harvest and the processing that yields ganja, charas, hashish, bhang and hemp fibre. This portal covers those practices where landrace populations are grown, together with what farmers know about them.

In the licensed ganja tract of colonial Bengal a specialist called the poddar went through each field before it flowered and broke the stalks of the male plants, since a few males left standing set the crop to seed. In the Himalayas resin is rubbed off the living flowering tops between the palms to make charas. In Afghanistan the dried plants are threshed and sieved into a resin powder that is pressed into hashish. In north-east Thailand seedless flowering tops were tied around slivers of bamboo to make the Thai stick, exported from the late 1960s until the 1980s. In the Rif of Morocco European demand from the 1960s and 1970s turned growers from kif to hashish.

The topics below are grouped by the portal's fifteen categories.

Did you know...
  • ...that in the licensed ganja fields of colonial Bengal a specialist called the poddar, or "ganja doctor", went through each field several times before it flowered, breaking the stalks of the plants he judged to be male?
  • ...that David Prain found the mark by which poddars told young male plants from female: solitary female flowers, often abortive, growing where the first male flower clusters would be expected?
  • ...that the Indian Hemp Drugs Commission of 1893–94 found only two ways of collecting charas in use on any considerable scale: rubbing the flowering tops between the palms and beating dried plants over cloth?
  • ...that flat ganja in Bengal was trodden flat by four or five people holding one another by the shoulders?
  • ...that the British Government Chemist rated Thai material the best-quality herbal cannabis it received in the mid-1970s, the years of the Thai stick trade?
  • ...that the Arabic word ḥashīsh, which gave hashish its name, means dry grass or herbage?
