Before feminized cannabis seeds were invented, the only option for home growers was to use regular cannabis seeds with them approximately producing 50% male and 50% female plants. In order to grow potent SENSIMILLA (Spanish for without seeds), the male plants had to be identified and thrown away to prevent them pollinating the females which would fill the plants with seeds and reducing THC levels.

In the 1990s DUTCH PASSION developed and introduced feminized seeds and with it created one of those few discoveries that have genuinely changed the way millions of people grow their own cannabis.

The introduction of feminized seeds means that only half as many cannabis plants need to be grown and allows the grow-room to be smaller, use less energy and be more efficient.
